Pros & cons
HiddenLayer AISec Platform 2.0
Pros: Strong on adversarial ML threats (model evasion, training-data poisoning) extending into memory poisoning at runtime.
Cons: Broad ML-security positioning means memory specifically isn't the focus; pricing is enterprise-tier.
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.
