Tessian Pricing FAQ

01 Can I still buy Tessian as a standalone product?

No. Proofpoint completed the Tessian acquisition in 2024 and folded the technology into two Proofpoint SKUs: Core Email Protection API and Adaptive Email DLP. The tessian.com pricing page now 301-redirects to a Proofpoint merger announcement.

02 What happened to existing Tessian customers?

Direct Tessian contracts are honored through their term, after which renewals migrate to the equivalent Proofpoint SKU. Renewal pricing is handled through Proofpoint sales, not a published price list.

03 Was Tessian's technology actually preserved?

Yes, per Proofpoint's announcement. The behavioral-AI engine powers Core Email Protection API (inbound anti-phishing) and Adaptive Email DLP (outbound misdirected-email prevention) — the two original Tessian capabilities.
