SME EDR 2026: Bitdefender vs Sophos vs Defender.
Comparison of the 3 SME EDRs. Criteria, pricing, recommendation by profile.
Bitdefender GravityZone Premium
SMEs 10-500 seats, demanding performance + simplicity
- ✓99.8% blocked in the AV-Comparatives Real-World Protection Test, March to June 2026, level with the best scores in the panel
- ✓Anti-ransomware with native file rollback
- ✓Unified cloud console for endpoints + servers + cloud workloads
- ✓Low CPU/RAM footprint on the workstation
- ✓EU vendor (Romania): GDPR native
- ✓Optional integrated MDR
- −Console offers less rich analytics than Sophos/CrowdStrike for an in-house SOC
- −ANSSI/NIS2 compliance reporting needs manual enrichment
SMEs without an in-house SOC, prioritising detection and a simple console
Sophos Intercept X Advanced with XDR
SMEs 20-500 seats, multi-vendor security
- ✓CryptoGuard anti-ransomware (rollback) + Deep Learning
- ✓Cross-source XDR (endpoint + firewall + email + cloud)
- ✓Synchronized Security with Sophos Firewall (auto-isolation)
- ✓Sophos MDR 24/7 available (English-speaking)
- ✓Very comprehensive Sophos Central console
- −Slightly higher workstation resource usage
- −Synchronized Security requires Sophos Firewall for the full benefit
- −Premium Sophos MDR pricing
SMEs running Sophos Firewall or looking for pre-integrated cross-source XDR
Microsoft Defender for Business
SMEs already on M365 (5-300 seats)
- ✓Included if M365 Business Premium is already purchased
- ✓Native AD/Entra/Intune integration
- ✓Anti-ransomware + EDR with attack surface reduction
- ✓Console in the unified Microsoft 365 Defender for email/endpoint/identity
- ✓Free ASR rules + threat & vulnerability management
- −Average detection vs Bitdefender/Sophos (top 5 but not top 1 on AV-TEST)
- −Console UX sometimes slow, multiple Microsoft portals
- −Support during a serious incident: escalation at Microsoft is painful
- −No full Linux endpoint support (Defender for Linux is limited)
SMEs that are 100% Microsoft 365 ecosystem and want to minimize the number of vendors

Recommendation by profile
→ Bitdefender GravityZone
Tied for the top score in the panel of the latest AV-Comparatives test, simple console, European vendor. Suited to teams without an in-house SOC.
→ Sophos Intercept X with XDR
Synchronized Security = automatic network isolation if an endpoint is compromised. Maximum ROI with a Sophos ecosystem.
→ MS Defender for Business
Already included in the license. Native AD/Entra/Intune integration. Sufficient for a moderate risk profile.
