APISec Platform vs Checkmarx API Security

APISec Platform is an application security tool for validating exploits against APIs and applications. It discovers applications, builds a dynamic model of their behavior, and runs attacker-like tests at runtime. The model can capture endpoints, parameters, authentication flows, roles, permissions, object ownership, and business logic without documentation or developer interviews. Tests cover business logic, data access, permissions, configuration, infrastructure, and controls such as injection and token handling. For validated exploits, the platform returns the request sequence, data reached, blast radius, replay, and a suggested resolution. APISec says it can find APIs across infrastructure, source, gateways, ingress and authentication paths, web apps, development tools, and CI/CD, as well as agents, MCP servers, and LLM call sites. Public APIs run against its cloud; private and on-premises APIs can use a Kubernetes or Docker container, while cloud deployments can run in a customer’s GCP, Azure, or AWS environment. The free plan covers public API testing and basic simulations. Standard costs $690 a month per 100 endpoints; Pro costs $2,750 a month per 100 endpoints.

Checkmarx API Security discovers APIs in application source code and documentation, including undocumented shadow APIs and abandoned zombie APIs. It builds a global inventory showing vulnerabilities and supports remediation prioritization by business risk. The scanner supports Java Spring, ASP.NET Web API and Python Flask, and examines OpenAPI, Swagger and Postman collections for documentation mismatches. An API Change Log records history, including the commit and developer linked to a vulnerability-introducing change. Checkmarx DAST findings can be correlated with SAST findings in the same inventory to identify runtime-confirmed issues. Integrations include GitHub, GitLab, Bitbucket, Azure DevOps, Jenkins, GitHub Actions, VS Code, JetBrains, Jira, Slack and Microsoft Teams. Security statements cover AES-256 encryption at rest, HTTPS with TLS 1.2, annual SOC 2 Type II audits and GDPR-aligned privacy practices. Deployment is cloud or hybrid. Pricing is custom, based on modules, deployment model and developers in scope; no self-serve trial is offered.
