Checkmarx One (2026 Edition)

An enterprise-grade AppSec platform centered on 'Agentic AI.' The 2026 version features autonomous AI agents for real-time remediation, 'Supply Chain Threat Intel' to block malicious OSS packages, and a unified 'Code-to-Cloud' dashboard. While its depth across 30+ languages is unmatched, its opaque pricing and $30k+ minimum contract values make it highly restrictive for small-to-mid-sized teams.
