Pros & cons

Lakera Guard / Lakera Red

Pros: Memory-aware guardrail product — Guard for runtime + Red for adversarial testing; covers prompt-injection-into-memory specifically.

Cons: Closed SaaS; rule library is opaque; per-call cost can be meaningful at high volume.

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.
