Mirror Security VectaX vs Witness AI for Employees: Side-by-Side Comparison (2026)

Mirror Security VectaX

Enterprise and mid-market security teams protecting vector databases and RAG pipelines should evaluate Mirror Security VectaX if encryption of AI model inference is a hard requirement, not a nice-to-have. The fully homomorphic encryption approach means queries run directly on encrypted embeddings without decryption, which addresses NIST PR.DS data security controls that most vector database tools skip entirely. Skip this if your priority is cost-efficient security or you're still in pilot phases with non-sensitive data; FHE's compute overhead is real, and deployment complexity demands teams comfortable with cryptographic infrastructure.

Witness AI for Employees

Mid-market and enterprise security teams dealing with shadow AI sprawl should start here; Witness AI for Employees maps employee LLM usage across your org and blocks prompt injection and jailbreak attempts before they become incidents. The platform covers ID.AM and PR.AA across the NIST CSF 2.0 framework, meaning you get real asset discovery of AI tools plus enforced access controls tied to actual policy, not just detection logs. Skip this if your org hasn't yet standardized on which AI tools employees can use; you'll need that baseline before Witness can protect it.
