Sublime Security competitors and assessment
Company assessmentDirect peers
- IRONSCALES: AI-powered email security platform focused on phishing protection, inbox-level detection, and abuse-mailbox automation. Closely comparable in target buyer (mid-market to enterprise) and AI-driven detection approach.
- Abnormal Security: AI-native email security platform protecting against BEC, phishing, and account takeover. Direct competitor targeting the same enterprise buyers with a similar AI-first architecture and managed detection approach.
- Avanan (Check Point Software): Cloud email security platform (now part of Check Point) protecting Microsoft 365 and Google Workspace from phishing, malware, and account takeover. Direct competitor in API-based email security with similar architectural approach.
Broad incumbents
- Proofpoint: Established enterprise email security leader offering threat protection, information protection, and compliance. Competes head-on in inbound email security with broader portfolio reach and deeper enterprise entrenchment.
- CrowdStrike Falcon: Endpoint and broader XDR platform that increasingly extends into email and identity threat detection. Represents the broader-incumbent threat as platform consolidation brings native email security into the XDR stack.
- Mimecast: Long-standing email security and resilience vendor covering email filtering, DLP, and archiving. Competes directly in the same enterprise email security RFPs with a more traditional signature-and-policy architecture.
- Microsoft Defender for Office 365: Native email security bundled into Microsoft 365 E3/E5 licenses. The primary price-anchored competitor for any third-party email security vendor, increasingly incorporating AI-based detections.
Regional players
- KnowBe4: Security awareness and phishing simulation leader that acquired Egress to expand into email security. Adjacent competitor addressing the human-layer email attack vector with overlapping enterprise security buyer.
Others
- Valimail: Email authentication (DMARC, SPF, DKIM) and anti-spoofing platform, and Sublime's announced partner. Complementary rather than competitive — together offering combined outbound authentication and inbound threat detection.
Emerging players
- Material Security: Email security and data protection platform that uses the inbox as a control plane for detection and response. Comparable in modern architecture and enterprise targeting, with overlap on abuse-mailbox automation.
