GLIMPS Email Security for M365 vs Sophos Email: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise security teams running Microsoft 365 need GLIMPS Email Security for M365 if phishing and BEC attacks are bleeding through your native defenses; its 500+ specialized detection rules and sub-3-second analysis time catch what basic M365 filters miss. The deep learning zero-day attachment scanning and real-time URL database backed by multi-engine antivirus scanning covers Detect and Data Security functions effectively, though this tool prioritizes blocking threats over post-incident response orchestration. Skip this if you're looking for a platform that also handles endpoint detection, incident response, or identity-based attacks; GLIMPS is email-only and expects your other tools to finish the job. Mid-market and enterprise teams already running Sophos endpoint or MDR will extract real value from Sophos Email because the threat intelligence flows both directions, catching BEC and supply-chain phishing that isolated email gateways miss. The 20+ ML models and native integration with Sophos X-Ops means suspicious emails trigger endpoint investigations automatically without manual handoffs. Skip this if your organization needs email security completely decoupled from your endpoint vendor, or if you're heavily invested in a non-Sophos EDR and want to avoid vendor consolidation.
