What is EDR, and how is it different from antivirus, MDR and XDR?

EDR (endpoint detection and response) is security software that continuously records activity on laptops, desktops and servers, flags suspicious behavior, and lets a defender investigate and contain an attack, for example by isolating a device from the network. Traditional antivirus focuses on blocking known malicious files. EDR assumes some attacks will get through and gives you the visibility and tools to respond.

• Antivirus / next-gen antivirus (NGAV): prevention, often using behavior and machine-learning models rather than only signatures.
• EDR: detection, investigation and response on each endpoint, usually operated by your own IT or security staff.
• MDR (managed detection and response): EDR plus a service where an outside team watches alerts and responds for you. CrowdStrike sells this as Falcon Complete, and SentinelOne’s Commercial tier includes managed threat hunting.
• XDR: extends detection beyond endpoints to identity, email, cloud and network data.

The practical question for a small business is not the acronym but who will act when an alert fires at 2 a.m. If the answer is “nobody”, a managed option or an automated tool like Defender’s automatic attack disruption matters more than extra features.

Best EDR solutions compared (pricing as of October 2026)

1. Microsoft Defender for Business: best value among the best EDR solutions

Price: $3.00 per user per month on an annual subscription. Limits: up to 300 users, up to five devices per user, no minimum device requirement.

Defender for Business bundles next-generation antivirus, AI-powered endpoint detection and response with automatic attack disruption, and automated investigation and response. Microsoft 365 Business Premium ($22.00 per user per month billed yearly) includes Defender for Business plus Intune Plan 1, so if you already pay for Business Premium you may already own EDR and only need to switch it on.

Pros

• Lowest published cost of the three, and per-user pricing covers several devices per person.
• Natural fit if you already use Microsoft 365, Entra ID and Intune.
• Automated investigation and attack disruption reduce the work for a small IT team.

Cons

• Not a managed service: someone needs to review alerts or you need a partner to do it.
• Strongest in Microsoft-centric environments.
• 300-user cap, so larger companies will outgrow it.

That combination of price, limits and automation is why Defender for Business sits among the best EDR solutions for small business. Choose it if you use Microsoft 365 and want solid EDR at the lowest cost. Skip it if you need a vendor-run 24/7 service or you run mostly non-Microsoft systems.

2. CrowdStrike Falcon: best dedicated platform among the best EDR solutions

Price: Falcon Go $59.99, Pro $99.99, Enterprise $184.99 per device per year, or $7.99, $14.99 and $19.99 per device billed monthly.

All three bundles include next-gen antivirus, device control, endpoint detection and response, and threat intelligence and hunting. The page also lists mobile device protection, identity protection, IT hygiene, Next-Gen SIEM and Express Support across the bundles. Pro and Enterprise add firewall management, and Enterprise has the most detailed descriptions of EDR and threat hunting, including hands-on hunting by expert analysts. Purchases of Falcon Go are limited to 100 devices. Falcon Complete, the fully managed service, is priced through sales, and Falcon Elite pricing is not published on the page.

Pros

• Clear, published per-device pricing with annual and monthly options.
• EDR, threat intelligence and hunting included even in the entry bundle.
• A managed option (Falcon Complete) when you want CrowdStrike to run it.

Cons

• Costs more per endpoint than Defender for Business.
• Falcon Go’s 100-device cap pushes growing teams to higher bundles.
• Managed service pricing is quote-only.

CrowdStrike earns its place among the best EDR solutions because even the entry bundle includes EDR, threat intelligence and hunting. Choose it if you want a dedicated, security-first EDR and have budget of roughly $60 to $185 per device per year. Skip it if you only need baseline protection and already own Defender through Microsoft 365.

3. SentinelOne Singularity: best managed-hunting option among the best EDR solutions

Price: Singularity Complete $179.99 and Commercial $229.99 per endpoint per year; Enterprise by quote. The page applies the price to 5 to 100 workstations.

Complete includes AI-driven protection for endpoints and cloud workloads, real-time threat detection and response, 14 days of data retention and an AI security assistant. Commercial adds identity detection and response, 90 days of data retention and managed threat hunting. Enterprise adds an AI SOC analyst for automated triage, full visibility and forensics, and expert-led onboarding. Purchases go through authorized partners, whose pricing controls if it differs from the page.

Pros

• Commercial tier includes managed threat hunting and 90-day retention.
• Identity detection and response available without jumping to Enterprise.
• Covers cloud workloads as well as endpoints.

Cons

• Highest published per-endpoint price of the three.
• Buying through partners means you must confirm the quote.
• 14-day retention on Complete may be short for investigations.

Among the best EDR solutions, SentinelOne is the one that bundles longer retention and managed hunting into a single tier. Choose it if you want longer data retention and managed hunting in one package. Skip it if price is the main constraint; the next table puts all three side by side.

How much do the best EDR solutions cost for 10, 50 and 100 devices?

Illustrative annual maths from the published list prices above. Defender is priced per user, so the figure assumes one user per device. Taxes, services and reseller discounts are excluded.

If your people each use two or three devices, Defender’s per-user model gets even cheaper per device, while CrowdStrike and SentinelOne price every endpoint.

Best EDR solutions by use case

The best EDR solutions differ depending on who will run them and how many devices you protect. Here is how the best EDR solutions line up for common situations.

Best EDR for small business on a budget

Microsoft Defender for Business at $3 per user per month.

Best EDR for a company that has no security staff

Choose a managed option: CrowdStrike Falcon Complete (quote) or SentinelOne Commercial with managed threat hunting ($229.99 per endpoint per year).

Best EDR for Microsoft 365 environments

Defender for Business, which is included in Microsoft 365 Business Premium.

Best EDR for 100 devices or fewer with threat intelligence

CrowdStrike Falcon Go, capped at 100 devices, or Pro if you want firewall management.

Best EDR with longer log retention

SentinelOne Commercial lists 90 days of data retention against 14 days on Complete.

How to choose between the best EDR solutions

Every one of the best EDR solutions looks good in a demo, so decide with a checklist instead of a feature count. Use these eight steps to shortlist the best EDR solutions for your size, budget and staff.

1. Inventory what you already pay for. Microsoft 365 Business Premium already includes Defender for Business.
2. Decide who responds. EDR creates alerts, and someone must triage them. If that is nobody, buy managed detection and response or a partner service.
3. Count endpoints and users separately. Defender prices per user, while CrowdStrike and SentinelOne price per device.
4. Check operating system coverage. Confirm Windows, macOS, Linux and mobile coverage for your fleet before you buy.
5. Look at retention and reporting. Longer retention helps investigations and audits.
6. Ask for a written quote when you buy through a partner, particularly for SentinelOne.
7. Check your cyber insurance. Insurers often ask whether you run EDR, so confirm what your policy expects.
8. Run a pilot on 5 to 10 devices for two weeks before rolling out.

Rollout checklist for the best EDR solutions

Whichever of the best EDR solutions you pick, a careful rollout decides whether it actually protects you.

1. Export an asset list of every laptop, desktop and server.
2. Remove or disable older antivirus agents to avoid conflicts.
3. Deploy to a pilot group and review alerts for false positives.
4. Write a one-page response plan: who triages, who isolates a device, who contacts the vendor.
5. Roll out in waves and confirm every device reports in.
6. Review alerts weekly for the first month and tune exclusions carefully.

Common mistakes when buying EDR solutions

Even the best EDR solutions fail when they are bought or deployed badly. Avoid these mistakes before you commit.

• Buying EDR with no one assigned to respond. Alerts without action are a false sense of security.
• Running two full EDR agents on one device, which can cause conflicts and performance problems.
• Comparing per-user and per-device prices directly. Convert to a cost per protected device first.
• Ignoring retention limits. Short log retention can limit how far back you can investigate.
• Skipping the pilot. Test with real applications before rolling out company-wide.
