Evaluate the risk of every model in use

Enrich the discovery sources you already run to evaluate the risk of every model in your environment, across first and third parties.

What's in every model report

PromptArmor traces where a model comes from, benchmarks how it performs, then red-teams it for the cyber and alignment risks it brings into your environment.

Compare models side by side

Put two models side by side on provenance, benchmarks, cyber and alignment risk, and data retention.

Tuned to how you'll use the model

The same model can be low-risk for coding and high-risk for handling patient data. PromptArmor re-scores cyber risk, alignment risk, cost, and benchmarks for the specific job you are putting it to.

Coding

Scored for code generation and agents: whether it can be driven to write malware, leak secrets, or run code it should not.

Cyber workflows

Scored for SOC and detection work: tool abuse, data exfiltration, and how it holds up running as an autonomous agent.

Legal

Scored for legal work: client confidentiality, privilege, and how often it fabricates citations.

Healthcare

Scored for clinical use: how it handles PHI and how often it invents facts in a medical answer.

Finance

Scored for finance: handling of material nonpublic information and susceptibility to fraud and social-engineering prompts.
