PromptArmor

PromptArmor is a platform for assessing and monitoring AI-related risk in third-party vendors. It addresses the challenge that traditional cybersecurity tools are not designed to handle the novel security threats introduced by AI systems, such as indirect prompt injection and data exfiltration. The platform provides continuous risk intelligence for what it terms the "agent supply chain," helping organizations evaluate new AI assets and monitor changes efficiently.

The platform offers risk scoring across 26 risk vectors, mapped to established frameworks including NIST AI RMF, OWASP LLM Top 10, and MITRE Atlas. Its capabilities are organized into modules for TPRM (vendor reports with AI-specific risk scores), InfoSec (indirect prompt injection risk assessment), Data Privacy (visibility into vendor data training and data flows), and Legal (insight into training data opt-out policies and data retention). The platform continuously monitors vendor portfolios for changes such as new models, expanded data access, or new features, and alerts users to shifts. It includes role-based access control, API access, and supports OAuth or SSO identity management.

The platform is built for security teams at enterprises, including those in Fortune 50 companies, law firms, and healthcare organizations. It is offered with a free trial covering up to five applications, which includes risk assessment and one month of continuous monitoring. An Enterprise edition provides coverage scaled to the full vendor ecosystem, with API access, role-based access control, dedicated research guidance, and premium support.
