Prompt Armor
AI vendor risk intelligence for enterprise TPRM teams
Prompt Armor is essential for large enterprises with heavy AI vendor dependencies. Its research-led threat intelligence on prompt injection and data exfiltration is unmatched, covering platforms like Claude, Google, Slack, and Writer.com. Overkill for small teams; choose Vanta or OneTrust if you need broader GRC without deep AI specialization. The free trial for 5 applications is a low-risk starting point, but full coverage requires a custom Enterprise plan.

About Prompt Armor
Prompt Armor is an AI risk intelligence platform for TPRM, InfoSec, privacy, legal, and GRC teams. It identifies which vendors use AI, assesses LLM interactions with data across 26 risk vectors aligned with OWASP LLM Top 10, NIST AI RMF, and MITRE Atlas, and continuously monitors for AI scope changes. The platform includes an assurance module for showcasing AI controls, and provides threat intelligence on novel AI attacks like indirect prompt injection. Recent research highlights vulnerabilities in Atlassian Rovo, Claude, Google, Slack, and Writer.com. It's designed for large enterprises with heavy AI vendor dependencies.
Behind the Verdict
Prompt Armor fills a specific niche: third-party AI risk. It's not a general GRC tool; it's a specialist that digs into how vendors use AI, what data flows into their models, and how those models could be exploited. The recent research on Atlassian Rovo shows they're actively uncovering vulnerabilities that general tools miss. If you're a large enterprise with hundreds of AI vendors, the continuous monitoring and threat intelligence are invaluable. But for smaller teams with limited AI exposure, the cost and complexity may not be justified. The free trial for 5 applications is a low-risk way to test value, but full coverage requires an Enterprise plan. Integration with ServiceNow, ProcessUnity, ZScaler, Netskope, and Archer helps fit into existing workflows, but the pricing is not public, so you'll need to engage sales.

Real-world workflow fit
Concrete scenarios for the personas Prompt Armor actually fits — and what changes day-one when you adopt it.
You need to assess AI risk for a new vendor. Use the free trial to run a full assessment across 26 risk vectors, review the AI-specific risk score, and check if the vendor trains on your data by default. You receive a report mapped to OWASP, NIST, and MITRE frameworks.
Outcome: You quickly identify high-risk areas and make a data-driven decision on whether to proceed with the vendor.
You set up continuous monitoring for a portfolio of AI vendors. You receive alerts when a vendor expands AI permissions or data access, such as Microsoft Copilot adding screen and camera analysis in voice sessions.
Outcome: You can proactively address potential data exfiltration risks before they become incidents.
You need to generate compliance reports for AI governance reviews. Using Prompt Armor's assurance module, you document your own AI controls and produce reports aligned with OWASP, NIST, and MITRE.
Outcome: You accelerate security reviews with partners and regulators, demonstrating strong AI governance.
Use Cases
- Assess AI risks of vendors during procurement
- Monitor third-party AI tools for changes in LLM permissions or data handling
- Generate compliance reports for AI governance reviews
- Map data flows between vendors' AI assets and corporate data
- Accelerate TPRM evaluations with automated AI risk scoring
- Showcase your own AI controls to partners for faster security review
- Prioritize remediation based on threat intelligence of novel AI attacks
Limitations
- Prompt Armor focuses on assessing and monitoring third-party AI vendor risk rather than providing runtime protection.
- Pricing requires sales engagement for enterprise plans, with only a free trial for up to 5 applications.
- It may be more suitable for larger organizations with complex vendor ecosystems.

Featured Head-to-Head Comparisons
Checkmarx vs Prompt Armor
If your primary concern is monitoring AI risks across your vendor ecosystem—especially detecting prompt injection and data exfiltration in third-party LLMs—Prompt Armor is the specialized choice. But if you need to secure AI-generated code in your own development pipeline, with SAST, SCA, and agentic workflows, Checkmarx is the stronger fit. Both are enterprise-grade with contact pricing; your decision hinges on whether you worry more about external vendor AI or internal code-level AI risk.
Alloy vs Prompt Armor
Pick Prompt Armor if your primary concern is AI-specific third-party risk and you need deep framework alignment (OWASP, NIST, MITRE). Choose Alloy if you're a regulated financial institution needing a unified identity, fraud, and compliance orchestration platform with broad data partner integration.
