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 Vigilance compared at SMB scale. Plus the MSP-delivered path most small businesses actually use.

Why this matters now

The cyber risk reality for SMBs

Attack target

43%

of cyberattacks target small businesses (Verizon DBIR)

Average breach cost

$3.3M

for SMB-class breaches in 2026 (IBM Cost of a Data Breach)

Closure rate

60%

of small businesses that suffer a breach close within 6 months

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

#1Huntress Managed EDR$3-9 / endpoint / mo

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.

#2Sophos MDR Essentials~$7-10 / endpoint / mo

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%.

#3Arctic Wolf MDR (entry tier)$44K/year for up to 100 users

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.

#4SentinelOne Vigilance~$7-15 / endpoint / mo combined

When already on SentinelOne platform

MDR add-on layer on top of Singularity platform licence. No hard endpoint minimum which is unusual. Combined cost of platform + Vigilance 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

If you already have an MSP, ask them what MDR they include or recommend before pricing direct. Many MSPs have negotiated partner pricing significantly below what you can get directly, and they're motivated to protect their managed service margin by offering you a competitive bundled rate.

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.

FAQ

Small business MDR questions

What's the cheapest MDR for small business?

Huntress Managed EDR at $3-9 per endpoint per month is the cheapest credible MDR option for SMBs. Through MSP partners the price drops to $2.50-3.50. For 100 endpoints that's $3,600 to $10,800 per year, which is dramatically cheaper than enterprise alternatives. The trade-off is no contractual SLA and limited cloud workload coverage.

Can a small business afford MDR?

Yes, in 2026 even very small businesses can afford credible MDR. Huntress at 50 endpoints (the minimum) costs $1,800 to $5,400 per year. Sophos MDR Essentials at 100 endpoints lands around $8,400 to $12,000 per year through partner pricing. Both are within reach for businesses generating $1M+ in revenue, especially given the cyber insurance premium offsets.

Is MDR cheaper than hiring one security person for a small business?

Almost always yes. A junior security analyst in 2026 costs $80,000 to $110,000 fully loaded. That same money buys 5-10 years of Huntress for a 100-endpoint SMB, or 2-3 years of Sophos MDR Essentials. And one analyst can't provide 24/7 coverage; an MDR can.

Do small businesses really need MDR?

The data says yes. 43% of cyberattacks target small businesses. Average breach cost for an SMB is $3.3 million. 60% of small businesses that suffer a breach close within six months. Cyber insurance carriers increasingly require managed detection as a precondition for coverage. The risk of not having MDR has become significantly larger than the cost of having it.

How do MSP-delivered MDR services work?

Your managed service provider (the IT company that handles your patching, helpdesk, and Microsoft 365 administration) wraps MDR into their monthly service contract. They typically resell Huntress or Sophos MDR with a markup. You see one bill, one point of contact, and the security service is integrated with the rest of your IT support. For most SMBs this is the path of least resistance and the lowest total cost.
