About

PromptArmor is a comprehensive AI governance and third-party risk management (TPRM) platform designed for enterprise security and compliance teams. As AI becomes embedded in nearly every vendor product, organizations face a new class of risk that traditional security reviews are ill-equipped to handle. PromptArmor closes that gap with purpose-built intelligence and automation. The platform works across five core workflows: Identify AI (discover which vendors are leveraging AI and what type), Assess AI (evaluate LLM behavior and data interactions across 26 risk vectors mapped to OWASP LLM Top 10, NIST AI RMF, and MITRE ATLAS), Monitor AI (receive alerts when AI scope, permissions, or functionality changes), Map AI (visualize relationships between AI assets and the data they touch), and Assurance (help your own organization showcase its AI controls to accelerate security reviews and close deals faster). PromptArmor serves cross-functional AI Governance Committees spanning TPRM, Information Security, GRC, Privacy, and Legal stakeholders. It is trusted by Global 2000 software companies, Fortune 50 healthcare and technology firms, Am Law 100 law firms, and major credit unions—collectively protecting over $2 trillion in market cap. By accelerating AI vendor assessments and providing continuous monitoring, PromptArmor enables security teams to show business value faster while maintaining a defensible AI risk posture.

Pros

Dramatic Time Savings on AI Vendor Reviews: Customers report massively reduced time to evaluate AI vendors, enabling security teams to demonstrate business value faster and keep pace with the rapid adoption of generative AI tools.
Comprehensive Framework Coverage: Risk assessments are mapped to multiple authoritative frameworks (OWASP LLM Top 10, NIST AI RMF, MITRE ATLAS), giving security and compliance teams defensible, audit-ready documentation.
Cross-Functional Platform for Entire AI Governance Committees: Designed to serve TPRM, InfoSec, GRC, Legal, and Privacy stakeholders from a single platform, reducing tool sprawl and improving cross-team alignment on AI risk.

Cons

Enterprise-Only Pricing: PromptArmor targets large enterprises and is available via sales demo only, making it inaccessible or cost-prohibitive for smaller organizations or startups.
Focused Solely on Third-Party / Vendor AI Risk: The platform is specialized for evaluating AI in vendor products rather than managing risk of internally built AI systems, which may require additional tooling for complete coverage.
