Pricing

Sophos uses custom quoting, making direct comparison difficult. Microsoft Defender for Business starts at just $3/user/month if you’re already paying for Microsoft 365—a significant advantage for SMBs already invested in the Microsoft ecosystem. However, Sophos’s bundled MDR upgrade path may offset higher per-seat costs for organizations prioritizing managed response.

Features & Deployment

Both deploy via cloud-managed consoles. Sophos Intercept X emphasizes ransomware protection (CryptoGuard) and optional MDR services through Sophos Central, making it a stronger choice if you want to scale from self-managed EDR to fully managed detection and response. Microsoft Defender for Business leans on tight M365 integration, auto-investigation, and threat/vulnerability management—ideal if your entire stack is already Microsoft.

Sophos’s tiering complexity can confuse buyers; Microsoft’s per-user model (covering multiple devices) is simpler but licensing nuances require careful review.

Ratings & Verdict

G2 Scores: Sophos Intercept X (4.6/5, 350 reviews) edges Microsoft Defender for Business (4.4/5, 300 reviews).
Our Score: Sophos 8/10 | Microsoft 7.8/10

Choose Sophos Intercept X if:

• Ransomware protection is non-negotiable
• You want a potential upgrade to managed EDR/MDR
• You prefer vendor independence from Microsoft
• You can negotiate volume pricing

Choose Microsoft Defender for Business if:

• You’re already committed to M365 Business Premium
• Budget is tight and you want native cloud integration
• Simplicity and auto-investigation appeal to you
• Your team is familiar with Microsoft’s security posture

Sophos has a slight edge on specialized threat protection and flexibility; Microsoft wins on cost-of-ownership within its ecosystem and ease of deployment for Microsoft-centric shops. For pure SMB EDR, neither is a runaway winner—context (existing stack, ransomware risk, budget) determines the better fit.
