Best MDR for Small Business 2026 - Affordable Managed Detection Under $50K/Year
Small businesses face the same cyber threats as enterprises but with a fraction of the budget. 43% of cyberattacks target small businesses, and the average cost of a data breach for companies with fewer than 500 employees is $3.3 million. You cannot afford a $300,000/year enterprise MDR solution, but you also cannot afford to leave your endpoints unmonitored. This guide ranks the most cost-effective MDR options for small businesses and provides concrete budget recommendations by endpoint count. The good news: genuine managed detection and response is now available for as little as $3,600/year.

Budget MDR Options Ranked for Small Business
Huntress is the clear winner for small business MDR on a budget. The MSP partner pricing of $2.50-3.50 per endpoint makes it accessible to businesses with as few as 50 endpoints. The base price includes managed EDR, identity threat detection, security awareness training, and managed SIEM - capabilities that other vendors charge separately for. The 50-seat minimum and monthly billing model remove the upfront commitment risk that annual enterprise contracts create. For a 100-endpoint company, annual cost ranges from $3,600 (MSP) to $10,800 (direct).
Sophos MDR Essentials provides 24/7 monitoring with threat notification and guidance. The Complete tier adds active response but costs 30-50% more. Sophos MDR works best when paired with other Sophos products (Intercept X, Sophos Firewall) because the integrated telemetry improves detection accuracy. Channel partner pricing varies, so get quotes from at least two Sophos partners. For a 100-endpoint company, annual cost ranges from approximately $8,400 to $12,000.
Arctic Wolf's entry-level MDR Basic starts at $44,000 per year for up to 100 users. This is a step up in both cost and capability from Huntress and Sophos. You get a dedicated Concierge Security Team, monthly posture reviews, and broader coverage scope including network and cloud. For businesses that can afford the $44K annual commitment, Arctic Wolf provides a more comprehensive managed security experience. The concierge model is particularly valuable for businesses without any internal security expertise.
If your business already runs SentinelOne Singularity for endpoint protection, adding Vigilance MDR is a cost-effective way to get managed monitoring without switching platforms. The incremental cost of Vigilance at $17-50 per endpoint per year on top of your existing platform licence is less than migrating to a bundled MDR provider. For a 100-endpoint company already on SentinelOne Complete, adding Vigilance costs approximately $1,700-5,000 per year incremental.

What to Prioritise on a Small Budget
If your budget is tight, not all MDR features are equally important. Focus your spend on the capabilities that provide the highest security return per dollar. The number one priority is 24/7 monitoring - this is what cyber insurers require and what prevents the most common breach scenario of alerts being ignored outside business hours. Everything else is valuable but secondary if budget forces trade-offs.
1. 24/7 Monitoring
The core value proposition of MDR. Without round-the-clock monitoring, alerts generated at 2 AM on a Saturday go unnoticed until Monday. 60% of breaches involve threats that dwelled in the environment for days or weeks because nobody was watching. This single capability is worth the entire MDR investment for most small businesses.
2. Threat Hunting
Proactive threat hunting catches sophisticated attacks that automated rules miss. Advanced persistent threats and living-off-the-land attacks evade signature-based detection. Human threat hunters look for patterns and anomalies that automation cannot identify. Most MDR vendors include basic threat hunting in the base price.
3. Identity Monitoring
Business email compromise and credential theft are the top attack vectors against small businesses. Identity monitoring for Microsoft 365 and Active Directory catches compromised accounts before they lead to data theft or ransomware. Huntress includes this in the base price.
4. Incident Response
When a threat is confirmed, someone needs to contain it. Basic MDR provides guidance on response. Premium tiers like Sophos MDR Complete actively contain threats for you. For businesses without IT security staff, active response is worth the premium because you may not have the expertise to execute containment instructions.
5. Cloud Monitoring
If you run production workloads in AWS or Azure, cloud monitoring adds visibility into a critical attack surface. However, many small businesses primarily use cloud for email (Microsoft 365) and storage rather than production infrastructure. Cloud workload monitoring is most valuable for SaaS companies and tech firms.
6. Compliance Reporting
MDR vendors provide security monitoring reports that satisfy cyber insurance requirements and compliance frameworks. While not a primary security capability, these reports save hours of manual work and can reduce audit costs. Most MDR vendors include basic compliance reporting in the base price.
MSP-Delivered MDR: The Cheapest Path for Small Business
The most cost-effective way for small businesses to access MDR is through a Managed Service Provider. MSPs get wholesale pricing from vendors like Huntress at $2.50-3.50 per endpoint and resell with their management services included. Beyond the pricing advantage, MSPs handle deployment, configuration, policy updates, and coordination with the MDR vendor - tasks that would otherwise require internal IT security expertise that most small businesses do not have. When evaluating MSPs, ask specifically which MDR vendor they use, what their per-endpoint pricing includes, and whether they provide a dedicated security point of contact for your account. The best MSPs act as an extension of your team rather than just a billing intermediary.
MDR for Small Business FAQ
What is the cheapest MDR service for small business?
Huntress is the most affordable MDR for small business at $3-9 per endpoint per month. For a 100-endpoint company, Huntress costs approximately $3,600-10,800 per year. MSP-delivered Huntress pricing is even lower at $2.50-3.50 per endpoint through a managed service provider. Sophos MDR Essentials is the next most affordable option at roughly $7-10 per endpoint per month. Both provide 24/7 monitoring and are well-suited to small business environments.
Do small businesses really need MDR?
Yes. 43% of cyberattacks target small businesses, and the average cost of a data breach for companies with fewer than 500 employees is $3.3 million. Small businesses rarely have dedicated security staff, which means alerts from EDR tools go unmonitored. MDR provides 24/7 monitoring and response for as little as $3,600 per year for 100 endpoints through Huntress. Cyber insurers are increasingly requiring MDR or equivalent 24/7 monitoring as a policy condition, and MDR can reduce insurance premiums by 15-25%.
How much should a small business budget for MDR?
For 50 endpoints, budget $1,800-$5,400 per year with a vendor like Huntress. For 100 endpoints, budget $3,600-$10,800 per year. For 250 endpoints, budget $9,000-$27,000 per year. These ranges represent the difference between MSP partner pricing and direct retail pricing. The cheapest path is usually through an MSP who resells Huntress or Sophos MDR at partner pricing. If your budget allows $30,000 or more per year, Arctic Wolf's entry tier becomes an option at $44,000 per year for up to 100 users.
Should a small business buy MDR through an MSP?
For most small businesses, buying MDR through an MSP is the most cost-effective and practical approach. MSPs get wholesale pricing from vendors like Huntress at $2.50-3.50 per endpoint that they pass along with a reasonable markup. More importantly, MSPs handle deployment, configuration, and ongoing management of the MDR tool, which eliminates the need for internal IT security expertise. The MSP also manages updates, policy changes, and coordinates with the MDR vendor on threat response.
What should small businesses prioritise when choosing MDR on a budget?
On a tight budget, prioritise 24/7 monitoring first since this is the core value of MDR and what your cyber insurer cares about most. Next prioritise threat hunting capability which catches advanced threats that automated detection misses. Incident response retainer hours are a nice-to-have but can be purchased separately if needed. Cloud workload monitoring and identity monitoring are valuable but can be deferred if budget is the primary constraint. A basic MDR that provides 24/7 endpoint monitoring is dramatically better than no MDR at all.
What are the red flags when evaluating budget MDR providers?
Watch for vendors that only provide automated alerting without human analyst review - that is just EDR with a notification layer, not MDR. Avoid vendors without clear SLAs for response time. Be cautious of extremely low pricing that omits critical capabilities like threat hunting. Check whether the vendor has a real SOC with named analysts or just forwards alerts from automated rules. Ask how many customers each analyst manages - ratios above 100 to 1 indicate thin coverage. Request references from businesses similar in size and industry to yours.
