Acquisition Upsell Opportunity Tessian's integration into Proofpoint creates a built in pathway to cross sell AI driven email security and data loss prevention to Proofpoint's large enterprise customers. Target organizations already invested in Proofpoint ESM who need enhanced protection against phishing, BEC, and insider threats, and position Tessian Respond and the M365 add in as complementary capabilities for faster remediation.

Legacy Gateways Replacement Tessian markets itself as an AI powered cloud email security layer that stops threats beyond legacy Secure Email Gateways, addressing gaps in traditional tooling. This positions it well against enterprises still relying on SEG based security; sales approach: quantify risk, show ROI of upgrading to cloud, integrated DLP and threat detection.

Independent Validation Forrester Wave Strong Performer (2023) provides independent validation for procurement teams and can shorten evaluation cycles; leverage this in RFPs and executive briefings when speaking to security leaders evaluating email security providers.

MS365 Integration Product milestones in 2023 including M365 Add in and Tessian Respond demonstrate ease of deployment and proactive threat hunting in Microsoft 365 environments; target mid market and enterprise customers migrating or expanding to M365 who seek seamless integration and faster incident response.

Security Culture Value Tessian emphasizes coaching users about security threats in the moment, enabling a security aware culture and reducing user caused data loss; this can be a differentiator when selling to organizations prioritizing user behavior risk and security training as part of a broader security program.
