Pros & cons
Acuvity (now Proofpoint)
Pros: Enterprise DLP for AI products — protects against data exfiltration via memory writes/reads; backed by Proofpoint's enterprise channel.
Cons: Enterprise-tier pricing and complexity; smaller mind-share than Lakera or Microsoft Defender for AI.
Mem0 Security / OpenMemory
Pros: Native privacy / governance hooks inside Mem0 — encryption, masking, retention policies as first-class config rather than bolt-ons.
Cons: Mem0-only; OpenMemory protocol is still emerging and lacks broad ecosystem support.
