Managed Detection and Response (MDR) for Small Businesses: Best Providers

The Security Gap Most Small Businesses Don’t Know They Have

Ransomware attackers dwell inside compromised networks for an average of 16 days before launching their final attack. During those 16 days, they move laterally from device to device, escalate their privileges, identify your backup systems, and disable your defences. The actual ransomware deployment — the thing that locks your files — is the last step of an attack that started weeks earlier.

Traditional endpoint security tools — antivirus, EDR — detect threats at the device level. They’re excellent at stopping known malware. They’re less effective at catching the stealthy pre-attack phase: the living-off-the-land techniques where attackers use legitimate Windows tools, the credential theft that looks like normal login activity, the persistent footholds installed quietly in scheduled tasks and registry keys.

Detecting that pre-attack activity requires human analysts watching your environment around the clock — people who know what normal looks like and can spot the subtle deviations that automated tools classify as routine. Most small businesses can’t afford to hire those people. That’s what Managed Detection and Response (MDR) provides.

An MDR service combines threat detection technology with a 24/7 Security Operations Centre (SOC) staffed by human security analysts. When something suspicious happens on your network — at 3am on a Saturday, or in the middle of a holiday — those analysts investigate, determine whether it’s a genuine threat, and either contain it directly or send you a plain-English report telling you exactly what to do. You get a security team without hiring one.

The honest caveat before we review providers: MDR is not magic. It closes specific gaps that self-managed endpoint security leaves open. If your business doesn’t have basic hygiene in place — regular patching, MFA on every account, a tested backup — MDR will catch more of what gets through, but it won’t compensate for unpatched systems that let attackers in easily. MDR is the right next step after you’ve got the fundamentals right.

Top pick for most small businesses: Huntress is the most accessible MDR for businesses under 200 devices, with the best price-to-protection ratio in the category and a 4.8/5 G2 rating from over 1,000 verified reviews.

Quick Picks: Best MDR for Small Business 2026

• Best overall for SMBs: Huntress — purpose-built for small and mid-sized businesses, 24/7 human SOC included, persistent foothold detection, $2.50–$9/endpoint/month depending on channel.
• Best for mid-market businesses wanting a named security team: Arctic Wolf — Concierge Security Team model with named analysts, broader coverage (network, cloud, identity), higher price point (~$36+/user/month).
• Best for Sophos ecosystem users: Sophos MDR — natural add-on for businesses already running Sophos Intercept X, full IR on MTR Complete tier, ~$7–$17/endpoint/month.
• Best for Microsoft 365-heavy environments: Huntress with ITDR — Huntress Managed Identity Threat Detection and Response covers Microsoft 365 session hijacking and account compromise alongside endpoint protection.

What MDR Is (and What It Isn’t)

Before comparing providers, the distinction between three commonly confused terms is worth establishing clearly.

EDR (Endpoint Detection and Response) is software installed on your devices that monitors for suspicious behaviour and generates alerts. It doesn’t have humans watching those alerts. You — or your IT person — are responsible for reviewing them.

MDR (Managed Detection and Response) is EDR plus a team of human analysts who monitor those alerts around the clock. When the software detects something suspicious, a human investigates it, determines whether it’s a real threat, and either takes action or contacts you with guidance. You don’t review alerts. You receive phone calls or reports when something actually matters.

SIEM (Security Information and Event Management) collects logs from across your environment and correlates them to identify patterns. MDR services often use a SIEM component internally, but buying a SIEM and managing it yourself is a different, more complex undertaking. The SIEM article elsewhere on SmallBiz Defense covers that in detail.

The question for a small business is simple: do you have someone who will watch the alerts that your security tools generate? If the answer is yes — an IT administrator with security knowledge who actively reviews alerts daily — you may do well with self-managed EDR. If the answer is no — the IT function is the owner, a generalist admin, or an MSP who doesn’t actively monitor security alerts — you need MDR.

MDR is the right choice if:

• You have no dedicated IT security function at your business
• Your IT provider manages your systems but doesn’t actively monitor security alerts
• You’ve experienced a security incident and want ongoing professional monitoring
• A cyber insurance policy or compliance framework requires demonstrable 24/7 security monitoring
• You want to know immediately if something is happening on your network, not hours or days later

How We Evaluated These Providers

We assessed each MDR provider against five criteria specific to small business needs.

Response model: Does the provider take action on your behalf (isolating devices, terminating processes, blocking connections) or do they alert and advise? The difference between an MDR that contains a threat autonomously and one that sends you an email at 3am telling you to do something is significant.

SMB accessibility: Minimum contract sizes, per-endpoint minimums, pricing transparency, and whether the service model works for a 20-person business without a security team.

Coverage scope: Does the service cover endpoints only, or does it extend to Microsoft 365, cloud infrastructure, network traffic, and identity systems? The scope directly affects which attacks the provider can detect.

Alert quality: Do analysts filter out false positives before contacting you? The value of MDR relative to self-managed EDR is fewer, higher-quality alerts — not more of them.

Pricing clarity: Can you estimate your annual cost without going through a week of sales calls? Transparency matters for SMB budget planning.

We reviewed G2, Gartner Peer Insights, and PeerSpot user reviews, sourced pricing from independent MDR pricing databases (MDRCost.com, verified July 2026), and cross-referenced with MSP community reporting.

Individual Reviews

Huntress — Best Overall MDR for Small Businesses

Huntress was founded by former NSA operators in 2015 with a specific mission: make enterprise-grade threat detection accessible to small businesses that can’t afford a security team. In 2026 it remains the most purpose-built MDR for the SMB and MSP market, with a 4.8/5 rating on G2 from over 1,086 verified reviews and a 9.4/10 on PeerSpot — the highest independently measured SMB satisfaction scores in the managed detection and response category.

What it is: A modular managed security platform combining Managed EDR (endpoint detection and response), Managed ITDR (Identity Threat Detection and Response for Microsoft 365), Managed SIEM, and Security Awareness Training. Every product includes 24/7 monitoring from Huntress’s human-led, AI-assisted SOC. The SOC reviews every alert before it reaches the customer — MSP partners and direct customers receive fewer than 1% of raw alerts as actual incidents.

What we liked:

Persistent foothold detection is Huntress’s most distinctive technical capability and the one most directly aligned with how real attacks unfold. Rather than focusing exclusively on malware execution, Huntress specifically hunts for persistence mechanisms: the scheduled tasks, registry run keys, service installations, and startup entries that attackers use to maintain access even after the obvious entry point is blocked. In the 16-day pre-attack dwell period described above, these persistent footholds are what attackers establish. Huntress finds them.

One-click remediation with step-by-step guidance is the operational model that makes Huntress work for non-security staff. When a genuine threat is confirmed, the Huntress SOC sends a plain-English incident report explaining what happened, what the impact is, and exactly what to do — written for a business owner or generalist IT person, not a security analyst. With pre-authorisation, the SOC can also contain threats autonomously — isolating a compromised device, terminating a malicious process, quarantining a file — without waiting for human approval.

The MSP channel model is how most small businesses access Huntress at the lowest cost. Huntress sells primarily through Managed Service Providers who aggregate multiple small clients to meet volume thresholds. MSP partner rates run approximately $2.50–$3.50/endpoint/month — significantly below the direct retail rate of approximately $8.99/endpoint/month. For a 20-device business whose IT is managed by an MSP, Huntress-powered security is often already available as an add-on to the existing IT management relationship.

Microsoft 365 ITDR coverage addresses a gap that endpoint-only MDR misses. Huntress Managed ITDR specifically monitors for account compromise, session hijacking, MFA bypass, OAuth app abuse, and privilege escalation within Microsoft 365 — attacks that never touch the endpoint and therefore bypass EDR entirely. For a business where employees primarily work in Microsoft 365 (email, SharePoint, Teams, OneDrive), ITDR adds meaningful detection coverage that pure endpoint MDR doesn’t provide.

What we didn’t like:

The 50-endpoint minimum on direct purchases creates friction for very small businesses. A 10-person company with 12 devices can’t purchase Huntress directly without paying for 38 unused licences. The practical solution is purchasing through an MSP partner who aggregates multiple small clients — but this requires having an MSP relationship in the first place.

Coverage scope is narrower than enterprise MDR providers like Arctic Wolf. Huntress focuses on endpoints and Microsoft 365 identity. Network traffic monitoring, cloud infrastructure (AWS, Azure, GCP), and complex SIEM integrations are not Huntress’s primary focus. For businesses with significant cloud-native infrastructure, Arctic Wolf or Sophos MDR with broader telemetry scope may be a better fit.

No published contractual SLA for response time. Huntress does not commit to specific Mean Time to Detect or Mean Time to Respond figures in a contract. For businesses with cyber insurance or compliance requirements that specify response time SLAs, this is a gap to address before signing.

Pricing (verified July 2026): Direct retail approximately $8.99/endpoint/month for Managed EDR. MSP channel rates approximately $2.50–$3.50/endpoint/month (aggregated into MSP managed services billing). Add-ons: Managed ITDR approximately $4.80/identity/month; Managed SIEM approximately $4.00/data source/month. 50-endpoint minimum on direct accounts. 12-month standard term, monthly billing in arrears.

Best for: Small and mid-sized businesses (50–500 devices) accessed through an MSP, or direct businesses with 50+ endpoints. Best fit for Microsoft 365-centric environments where endpoint plus identity coverage is the primary need.

Rating: 4.8/5

Arctic Wolf — Best for Mid-Market Businesses Wanting a Named Security Team

Arctic Wolf is the MDR provider for a small business that has outgrown the “set and forget” model and wants an ongoing relationship with named security professionals who understand their environment. The Concierge Security Team model — where every customer is assigned a named team of analysts who hold regular security reviews — differentiates Arctic Wolf from volume-managed SOC services where your environment is one of thousands being monitored by rotating shift analysts who’ve never heard your company’s name.

What it is: A full-stack managed security platform covering endpoints, network, cloud, and identity. Arctic Wolf’s Security Operations Cloud collects telemetry from across the environment and analysts — supported by AI-driven detection — conduct continuous threat hunting, incident response, and quarterly security journey reviews. The platform covers Microsoft 365, Azure, AWS, on-premise network infrastructure, and physical endpoint devices from one engagement.

What we liked:

The Concierge Security Team model delivers relationship-led security at a level that most small businesses have never experienced. Your named team conducts monthly security reviews, tracks your organisation’s security posture over time, and proactively recommends improvements — not just responding to incidents but helping you reduce the conditions that enable them. Multiple G2 and Gartner Peer Insights reviewers specifically describe Arctic Wolf as functioning like an extended member of their own team rather than a remote monitoring service.

Coverage breadth is the strongest in this comparison for SMBs reaching mid-market scale. Arctic Wolf monitors endpoints, network traffic, Microsoft 365, Azure AD, cloud infrastructure, and on-premise servers from one platform. Threats that move laterally from a compromised endpoint into Azure infrastructure, or from a phished email account to a cloud application, are visible across the full chain in a way that endpoint-only MDR cannot see.

The $3 million breach warranty with qualifying bundles demonstrates meaningful confidence in the service’s effectiveness — and provides some financial backstop for the business in the event of a qualifying breach incident.

What we didn’t like:

The price is significantly higher than Huntress for comparable SMB deployment sizes. Arctic Wolf entry pricing typically starts around $44,000/year for 100 users — approximately $36+/user/month — compared to Huntress at approximately $3/endpoint/month through an MSP. For a 20-person business, that price gap represents thousands of dollars per year.

Arctic Wolf’s response model is primarily guided rather than autonomous. When a threat is confirmed, Arctic Wolf advises your team on what to do rather than automatically taking containment action. For a business without any IT staff, receiving a recommendation to isolate a device at 2am requires someone to act on that recommendation. Huntress’s autonomous response model (with pre-authorisation) is more appropriate for businesses with no in-house IT capability.

Annual price escalation clauses of 3–7% are standard in Arctic Wolf contracts. Over a three-year commitment, this compounds meaningfully. Negotiate the escalation clause down or out before signing.

Pricing (verified July 2026): Starting approximately $44,000/year for 100 users on MDR basis. Per-user rates approximately $36–$40/user/month at SMB volumes of 100–500 users. Multi-year contracts with 3–7% annual escalation clauses. Custom quotes required.

Best for: Small businesses with 50–500 users that want a named security team, proactive security posture coaching, and broader coverage across network, cloud, and identity — and can justify the higher price point for relationship-led service.

Rating: 4.5/5

Sophos MDR — Best for Sophos Ecosystem Users

Sophos MDR is the natural evolution for businesses already running Sophos Intercept X endpoint protection or Sophos firewalls. It layers 24/7 human-led monitoring and response on top of the Sophos platform’s existing detection capability — and critically, it benefits from Synchronized Security, where threat intelligence is shared across endpoint, firewall, and email in ways that create correlated detection unavailable to technology-agnostic MDR providers.

What it is: A managed detection and response service built on Sophos’s platform, available in Essentials and Complete tiers. MDR Essentials provides 24/7 monitoring, threat containment, and guided remediation. MDR Complete adds full incident response — Sophos analysts actively investigate and remediate threats on your behalf, not just advise — and includes a breach warranty. Both tiers monitor endpoints, network (via Sophos Firewall integration), email, and cloud environments.

What we liked:

The Synchronized Security integration is the core reason to choose Sophos MDR over a technology-agnostic provider if you’re already in the Sophos ecosystem. When Sophos Intercept X detects a threat on an endpoint, the Sophos Firewall automatically blocks network traffic from that device. When Sophos Email Security detects a phishing campaign, that intelligence enriches endpoint detection for the same sender. Sophos MDR analysts see all of this in one correlated view — a threat chain that a technology-agnostic MDR watching only endpoint telemetry cannot see.

MTR Complete tier provides genuine incident response — analysts actually investigate and remediate threats, not just detect and notify. For a business with no IT security function, the difference between “we detected a threat and sent you an email” and “we investigated, contained, and remediated the threat” is the difference between a security incident becoming a breach and not.

Integration with over 350 third-party security technologies means Sophos MDR can ingest telemetry from non-Sophos tools, making it viable even for businesses with mixed security stacks. Though the strongest value is in Sophos-native environments, the 350+ integration library makes it functional alongside other vendors.

What we didn’t like:

G2 reviewers who are small businesses consistently flag the price as a barrier. Sophos MDR is priced in the $7–$17/endpoint/month range, above Huntress’s SMB-friendly rates. Multiple reviewers describe the cost as the primary obstacle to adoption.

MDR Essentials does not include full incident response. Guided remediation — sending recommendations to your team — is not the same as actually doing the work. For businesses without IT security staff who need someone to take action when it’s 3am, Essentials falls short of what MTR Complete provides. Verify which tier you’re purchasing and what the response model actually includes.

Linux server protection requires a separate Sophos Workload Protection subscription rather than being included in the MDR tier.

Pricing (verified July 2026): Approximately $7–$17/endpoint/month depending on tier and volume. Complete tier (full incident response) at the higher end of that range. Custom quotes required; Sophos sells through resellers and partners.

Best for: Businesses already running Sophos Intercept X endpoint protection or Sophos firewalls, where Synchronized Security delivers correlated detection that a technology-agnostic MDR cannot replicate.

Rating: 4.4/5

Blackpoint Cyber — Best Mid-Range Option Between Huntress and Arctic Wolf

Blackpoint Cyber occupies the space between Huntress’s SMB-optimised pricing and Arctic Wolf’s concierge-relationship model. It provides genuine 24/7 SOC monitoring with active threat response, covers endpoints across Windows, macOS, and Linux, and is primarily distributed through the MSP channel — making it accessible at sub-enterprise pricing for small businesses managed by an IT provider.

What it is: A managed detection and response platform with a proprietary SNAP-Defense technology that specifically focuses on lateral movement detection — catching attackers as they move from a compromised device to other systems on the network, which is the phase traditional EDR typically misses. Offered through MSP partners; direct purchasing is possible but less common.

What we liked:

SNAP-Defense lateral movement detection is the distinctive technical capability. Where most endpoint MDR tools detect threats at the point of entry or execution, Blackpoint’s architecture is specifically designed to catch attackers after they’ve established a presence and are attempting to spread. This directly addresses the 16-day dwell period problem — it’s monitoring for the behaviour that characterises the pre-ransomware phase.

SOC analysts take active response actions — not just alerting and advising. When a threat is confirmed, Blackpoint’s SOC isolates the device, terminates the process, and contains the threat autonomously with appropriate pre-authorisation. The response model is more active than Arctic Wolf’s guided approach and comparable to Huntress.

MSP channel distribution makes Blackpoint accessible at approximately $8–$12/endpoint/month through most providers — above Huntress but below Arctic Wolf for comparable protection.

What we didn’t like:

Coverage scope is primarily endpoint-focused. Network traffic analysis and extensive cloud infrastructure monitoring are less prominent than Arctic Wolf’s full-stack approach. For businesses with significant cloud-native infrastructure beyond Microsoft 365, coverage may not match the breadth of Arctic Wolf.

Less established review volume than Huntress or Sophos MDR. While user reviews that exist are positive, the smaller review count provides less certainty than providers with 1,000+ verified reviews.

Pricing (verified July 2026): Approximately $8–$12/endpoint/month through MSP channels. Direct pricing available through Blackpoint’s partner network.

Best for: Mid-sized small businesses (50–200 devices) managed by an MSP that want more active lateral movement detection than Huntress provides but don’t need Arctic Wolf’s full concierge model.

Rating: 4.3/5

SentinelOne Vigilance — Best for Existing SentinelOne Customers

SentinelOne Vigilance is the managed detection and response add-on for businesses already running SentinelOne Singularity. It layers 24/7 SOC monitoring and human analysis on top of SentinelOne’s AI-driven autonomous detection — combining the world’s most capable autonomous threat response with human oversight for the threats that AI doesn’t fully resolve.

What it is: A managed SOC service sold as an add-on to SentinelOne Singularity Commercial and above. Vigilance analysts provide 24/7 monitoring, threat hunting, and guided remediation. One-click Rollback — SentinelOne’s autonomous ransomware recovery capability — operates independently of Vigilance and remains active regardless.

What we liked:

One-click Rollback is available without the Vigilance add-on — it’s part of the underlying SentinelOne platform. Vigilance adds human oversight on top of a product that already autonomously contains and reverses ransomware. For a small business that has invested in SentinelOne’s autonomous AI, adding Vigilance upgrades from “autonomous response I’m not monitoring” to “autonomous response with humans watching for what AI misses.”

MITRE ATT&CK framework alignment in Vigilance’s investigation methodology provides consistent, structured analysis that documents how threats mapped to known attack patterns.

What we didn’t like:

Managed detection and response requires SentinelOne Singularity Commercial or above ($229.99/endpoint/year) before Vigilance can be added. The platform entry cost is higher than Huntress’s all-in price. For a business not already running SentinelOne, the total cost of the platform plus Vigilance is difficult to justify over Huntress or Sophos MDR.

Pricing (verified July 2026): SentinelOne Vigilance pricing is approximately $229.99/endpoint/year inclusive — but this requires the underlying Singularity platform. Total cost for Singularity Complete (with Vigilance) is available through SentinelOne’s reseller network.

Best for: Businesses already deployed on SentinelOne Singularity that want to add professional monitoring without switching platforms.

Rating: 4.2/5

Comparison Table: Best MDR Providers for Small Business 2026

Buyer’s Guide: What a Small Business Actually Needs From MDR

What should a small business look for in an MDR provider?

The single most important question is not “how many threats do they detect?” — every provider in this review has strong detection. The question is: what does the provider actually do when they detect a threat?

There are two fundamentally different response models in this market:

Active response: The SOC takes action on your behalf — isolating a device from the network, terminating a malicious process, blocking a connection, disabling a compromised account. This happens automatically (with pre-authorisation) or on confirmation from the analyst, without requiring you or your IT team to do anything. Huntress and Blackpoint Cyber operate this model.

Guided response: The SOC detects a threat, investigates it, and sends you or your IT team instructions on what to do. You or your MSP take the action. Arctic Wolf (base tier) operates primarily this model. Sophos MDR Essentials is similar.

For a small business with no IT security function — where the person receiving the 3am alert about a compromised device is the business owner — guided response is not adequate. You need a provider who can contain the threat while you sleep. Verify the response model explicitly before signing.

After response model, prioritise: coverage scope (do they monitor where your business operates — endpoints, Microsoft 365, cloud?), minimum commitment size relative to your device count, and pricing transparency.

What’s the difference between MDR and hiring a security analyst?

A skilled security analyst in the US earns approximately $95,000–$130,000/year in base salary, plus benefits, training, and overhead. Security analysts typically work business hours and need coverage for nights, weekends, and vacations — so a genuine 24/7 SOC requires three to four analysts per shift position, minimum. Building a 24/7 internal SOC for a 30-person business would cost $500,000+/year before you factor in the technology.

MDR provides the equivalent of that coverage at $3–$17/endpoint/month — for a 30-device business, $1,080–$6,120/year. The economics are not subtle. For any small business, outsourcing the security operations centre is dramatically more cost-effective than building one internally.

How much should a small business expect to pay?

For a 20-device business accessed through an MSP with Huntress: approximately $600–$840/year in managed security cost (at MSP channel rates of $2.50–$3.50/endpoint/month). This is the most accessible price point for genuine 24/7 MDR.

For a 50-device business buying Huntress directly: approximately $5,394/year ($8.99 × 50 × 12).

For mid-market MDR (Sophos MDR Complete or equivalent) at 50 devices: approximately $4,200–$10,200/year.

For Arctic Wolf at 100 users: approximately $44,000/year.

The right budget anchor for most small businesses: if your current managed IT provider isn’t already including Huntress or a comparable MDR in your monthly IT service fee, adding it separately typically costs $3–$10/endpoint/month depending on provider and volume.

What to Avoid

Don’t confuse “monitoring” with “response.” Several products in this category advertise 24/7 monitoring but provide only detection and alerts, not containment. If the service sends you an email when your network is compromised rather than actively containing the threat, that is monitoring — not managed detection and response. Before signing, ask specifically: “What actions does your SOC take without requiring my approval?” If the answer is “none — we advise and you act,” that service is closer to managed detection than managed response.

Don’t sign an MDR contract without understanding the minimum commitment. Enterprise MDR providers routinely require 12-month contracts with device minimums of 100, 200, or more. A 20-device small business forced into a 100-device minimum pays for 80 unused licences every month. Access Huntress through an MSP partner — where the MSP aggregates multiple small clients to meet volume thresholds — or confirm explicitly that the provider can accommodate your actual device count.

Don’t buy MDR before fixing the basics. MDR detects and responds to attacks after they begin. If your business has unpatched software, weak passwords, no MFA, and no backup, attackers will find easy entry points that MDR will be constantly managing. The return on investment from MDR improves significantly when you’ve addressed the conditions that let attackers in easily. Patch all software, enforce MFA on every business account, and implement tested backup before or alongside MDR deployment.

Final Verdict

For most small businesses, Huntress is the right starting point for MDR. It’s the only provider in this roundup purpose-built for the SMB and MSP market, with pricing accessible through an MSP partner at rates that most small businesses can absorb, a human SOC that takes active response on your behalf, and persistent foothold detection that addresses the pre-attack dwell period that endpoint security alone misses. The 4.8/5 G2 rating from over 1,000 verified reviews is the strongest independent user satisfaction signal in the managed detection and response category.

If your business has grown past 50 devices, wants broader coverage across network, cloud, and identity systems, and can justify a higher investment in a named security team relationship: Arctic Wolf is the right next step. The Concierge Security Team model and posture coaching capability turn MDR from reactive incident response into ongoing security programme development.

For Sophos ecosystem users already running Sophos Intercept X or Sophos firewalls: Sophos MDR Complete is the natural addition, providing correlated detection across Sophos’s integrated platform that a technology-agnostic provider can’t replicate.

Whatever you choose: the gap between endpoint security that detects threats and managed detection and response that contains them is the gap ransomware operators exploit. Closing it with 24/7 human monitoring is not a luxury reserved for large enterprises. The pricing in 2026 makes it accessible to any business with a modest monthly IT budget.

Frequently Asked Questions

What is the difference between MDR and EDR?

EDR (Endpoint Detection and Response) is software that detects and records suspicious activity on your devices. It generates alerts when something looks suspicious. You — or your IT team — are responsible for reviewing those alerts, investigating threats, and responding. MDR (Managed Detection and Response) is EDR plus a team of human security analysts who do all of that on your behalf, 24/7. The alerts still get generated, but they go to trained analysts who investigate them, filter out the false positives (which typically represent over 99% of raw alerts), and contact you only when a genuine threat is confirmed. For a business without dedicated IT security staff, MDR turns EDR from a tool that generates unread alerts into an active protection service.

How long does MDR take to set up?

Huntress deployment across a small business fleet typically completes in under 30 minutes from account creation to all devices reporting to the SOC. The Huntress agent is lightweight, requires no reboots, and begins monitoring immediately. Sophos MDR requires the underlying Sophos Intercept X agent to already be deployed, and the MDR service activation adds a few hours of configuration. Arctic Wolf’s onboarding is more involved — connecting the platform’s sensors to your environment and completing the Concierge Security Team intake typically takes 2–4 weeks from contract signature to full operational coverage. For businesses that need protection running today, Huntress’s rapid deployment is a meaningful advantage.

Does MDR replace my antivirus?

It depends on the MDR provider. Huntress installs its own lightweight agent and manages Microsoft Defender Antivirus as part of the deployment — so it supplements your existing Windows protection without requiring a separate antivirus purchase. Sophos MDR requires Sophos Intercept X, which includes next-generation antivirus, so the MDR package replaces your standalone antivirus. Arctic Wolf is technology-agnostic and typically works alongside your existing endpoint security rather than replacing it, with sensors that monitor across your environment without requiring a specific antivirus product. Clarify with your chosen provider whether their MDR service replaces or supplements your current endpoint security before deployment.

Can a very small business (5–10 employees) afford MDR?

For direct purchases, most MDR providers have minimum commitments (50 endpoints for Huntress direct) that create friction for very small teams. The practical solution is accessing MDR through an MSP who manages multiple small clients and aggregates volume to meet provider minimums. An MSP offering Huntress-powered MDR typically includes it at $3–$5/endpoint/month as part of a managed IT services package — for a 10-person business with 12 devices, that’s $36–$60/month added to an existing managed IT relationship. For a business already paying $500–$1,000/month for managed IT services, adding MDR at $60/month is entirely accessible.

What happens when MDR detects a real threat at 3am?

With a provider using active response (like Huntress with pre-authorisation enabled): the SOC investigates the alert, confirms it as a genuine threat, autonomously contains it — isolating the compromised device from the network, terminating the malicious process, quarantining the associated file — and then sends you a plain-English incident report explaining what happened, what was done, and what follow-up is required. You wake up to a report, not an active breach. With a guided-response provider: the SOC detects and investigates the threat, then contacts you or your MSP with instructions on what to do. The action still requires a human to execute it. For businesses with no one on call at 3am, active response is the only model that provides genuine around-the-clock protection.
