Checkmarx vs Prompt Armor

Prompt Armor focuses exclusively on AI third-party risk: it identifies which vendors use AI, assesses LLM interactions across 26 risk vectors aligned with OWASP LLM Top 10, NIST AI RMF, and MITRE Atlas, and provides continuous monitoring for scope changes. Its threat intelligence has uncovered real vulnerabilities like data exfiltration via indirect prompt injection in ChatGPT for Google Sheets. It integrates with TPRM and GRC tools like ServiceNow and Archer. In contrast, Checkmarx is a broad AppSec platform covering SAST, Secrets Detection, IaC Security, API Security, SCA, Container Security, and AI-specific features like AI-BOM generation and DAST for AI-powered apps. Its Checkmarx MCP Server enables agentic workflows for triage and remediation. While Prompt Armor secures vendor AI, Checkmarx secures your own AI-generated code. Both are enterprise-focused, but their feature sets are complementary rather than overlapping.

Both Prompt Armor and Checkmarx require contacting sales for pricing, indicating enterprise-level investment. Prompt Armor targets TPRM, InfoSec, and GRC teams, likely pricing per monitored vendor or risk assessment volume. Checkmarx, as a full AppSec platform, typically scales with developers, applications, or scan volume. Neither offers a free tier or self-service pricing, so budget-conscious buyers should expect significant costs. Prompt Armor's focus on AI vendor risk might be more affordable for companies with a limited number of AI vendors, while Checkmarx's breadth could be cost-effective for organizations consolidating multiple security tools.
