Comparison
Best LLM security platforms: what enterprise buyers should evaluate.
The best LLM security platform is not simply the tool with the most detectors. Enterprise buyers need coverage across prompts, sensitive data, provider traffic, audit evidence, and governance workflows.
Control
Policy first
Map every AI interaction to allow, flag, mask, or block decisions.
Data
DLP aware
Detect sensitive prompts, regulated data, and document leakage risk.
Traffic
Gateway aligned
Apply controls before prompts reach external model providers.
Evidence
Audit ready
Keep explainable records for security, risk, and compliance reviews.
Evaluation criteria
A platform should control the full AI interaction, not just classify one prompt.
Buyers should compare whether a platform includes a prompt firewall, AI DLP, secure gateway architecture, governance, and enterprise audit. A detector-only product can help, but it often leaves rollout, policy, and evidence for internal teams to build.
Coverage
Surface coverage
Browser AI, applications, provider APIs, gateway routes, and developer workflows.

DLP
Data controls
Sensitive data detection, masking, document leak checks, and policy-aware decisions.
