How to evaluate Application Security
This is how the CIOPages Research Team evaluates this category. It is not an assessment of OWASP ZAP. It comes from our DevSecOps & Application Security Testing buyer guide.
25%
Finding Accuracy & Risk Prioritization
False-positive and false-negative rates on your own code; reachability analysis (is the vulnerable function actually called?); runtime/exposure context; EPSS/CVSS-based scoring; how a flood of findings collapses to a short, ranked, defensible work queue
20%
Developer Workflow Integration
Native IDE plugins, PR/MR checks and inline comments, SCM (GitHub/GitLab/Bitbucket/Azure DevOps) and CI/CD integration, quality/security gates, credible one-click autofix, and how little context-switching a developer needs to remediate
20%
Scanning Coverage & Engine Depth
SAST, SCA, secrets, IaC, container, and DAST/API coverage; supported languages and frameworks; vulnerability and malicious-package intelligence; SBOM generation and open-source license analysis; scan speed on large monorepos
15%
ASPM & Consolidation
De-duplication and correlation across first- and third-party scanners, code-to-cloud/runtime context, application risk graph or single risk score per app, policy-as-code, and openness to ingesting tools you already own rather than locking you in
10%
AI-Generated Code Security
Detection of AI-assisted/AI-authored code, guardrails for coding-assistant and agentic workflows, security of LLM/MCP integrations and open-source AI models, and whether the platform keeps pace with code generated faster than humans review it
10%
Governance, Compliance & Deployment
RBAC/SSO, audit trails and attestation, policy gates mapped to PCI-DSS/SOC 2/NIST SSDF, SBOM/VEX export, SaaS vs. self-managed/air-gapped and FedRAMP options, and clean API/data export for your own reporting
