Best MDR for small business: affordable options under $50K/year
Real vendor recommendations with concrete budget numbers. Huntress, Sophos MDR Essentials, Arctic Wolf entry tier, and SentinelOne Wayfinder MDR compared at SMB scale. Plus the MSP-delivered path most small businesses actually use.
The short answer
The most affordable credible MDR for a small business in 2026 is Huntress Managed EDR at $3-9 per endpoint per month (about $2.50-3.50 through an MSP partner). On a budget under $5,000 a year that covers roughly 50 endpoints across its full price range, or up to about 100 endpoints at MSP/entry pricing. Step up to Sophos MDR Essentials (~$7-10/endpoint/mo) when you want a higher service ceiling, and to Arctic Wolf (from ~$44K/year for up to 100 users) only once you want a named Concierge Security Team.

Huntress, ~50-100 endpoints

$44K+/year
Arctic Wolf, up to 100 users
Named Concierge Security Team and posture coaching. For matured SMBs.
Full per-endpoint breakdown at 50/100/250/500 endpoints, and the MSP-delivered path most SMBs actually use, are below.

Cyber insurance carriers have responded by tightening underwriting. Managed detection is increasingly required as a precondition for coverage, and the premium discounts for buyers with MDR in place are meaningful (15-25% off baseline). The risk equation has shifted: not having MDR is now more expensive than having it.
Top picks
Budget MDR options ranked with real pricing
Best value for SMBs under 200 endpoints
MSP partner pricing: $2.50-3.50/endpoint. Includes managed EDR, identity threat detection, and security awareness training in one bundle. 50-seat minimum, monthly billing in arrears, no annual lock-in.
Good fit for Sophos ecosystem buyers
Channel-led pricing through partners. Works alongside Microsoft Defender if you don't want a full Sophos rollout. 24/7 monitoring with 8-hour response SLA. Multi-year deals reduce annualised cost by 15-25%.
When SMBs want named analyst relationship
Most expensive option on this list at SMB scale, but the only one with a Concierge Security Team and posture coaching. Right answer when SMB maturity has outgrown Huntress and you want a real conversation about security strategy.
When already on SentinelOne platform
MDR add-on layer on top of Singularity platform licence (Wayfinder MDR, formerly Vigilance). No hard endpoint minimum which is unusual. Combined cost of platform + managed layer lands around $18 per endpoint per month at standard tiers.
Budget examples
What you'll actually pay at SMB scale
| Endpoints | Huntress | Sophos Essentials | Arctic Wolf entry |
|---|---|---|---|
| 50 | $1.8K-5.4K/yr | $4.2K-6K/yr | Below minimum |
| 100 | $3.6K-10.8K/yr | $8.4K-12K/yr | $44K/yr (base) |
| 250 | $9K-27K/yr | $21K-30K/yr | $36K-54K/yr |
| 500 | $18K-54K/yr | $42K-60K/yr | $72K-108K/yr |
For most small businesses, the realistic decision is between Huntress (the cheapest credible option) and Sophos MDR Essentials (slightly more expensive but with a higher service ceiling at scale). Arctic Wolf becomes interesting around 250-500 endpoints when the relationship-led model justifies the premium.
Priorities
What to prioritise on a small budget
- 24/7 monitoring over fancy threat hunting. Most SMB attacks happen on weekends and nights when you're not watching.
- Identity threat detection alongside endpoint coverage. Microsoft 365 account compromise is a leading attack vector for SMBs.
- Bundled security awareness training. If your budget is tight, Huntress gives you SAT for free as part of MDR rather than as a separate KnowBe4 contract.
- MSP delivery over direct purchase. Single bill, integrated support, your MSP knows your environment.
- No multi-year lock-in when starting out. Huntress's monthly billing lets you switch as your needs grow.
MSP path
Why most SMBs end up with MSP-delivered MDR
The numbers strongly favour going through your existing MSP rather than buying MDR directly. For a 100-endpoint SMB:
Through MSP
- One bill, one vendor relationship
- Integrated with patching, helpdesk, M365 admin
- MSP handles tier-1 incident response
- Often $5-12 per endpoint per month bundled
- No separate contract negotiation needed
Direct purchase
- Lower per-endpoint cost (you skip MSP markup)
- Direct relationship with vendor
- You handle integration with your tooling
- You own tier-1 incident response triage
- Suits SMBs with strong internal IT teams
Talk to your MSP first
Red flags
What to avoid when evaluating budget MDR
- No 24/7 SOC. If a vendor only monitors during business hours at the entry tier, walk away. Attackers don't keep office hours.
- Long contract lock-in with no out clause. 3-year contracts can save money but only if you can terminate for cause.
- No documented response SLA, even non-contractual. The vendor should publish target response times.
- Hidden onboarding fees not disclosed in the headline price. Ask explicitly.
- Required EDR replacement if you've already invested in Microsoft Defender for Business or similar. Sophos and Expel work alongside existing tools; insist on this if it matters to you.
