The OWASP Testing Guide defines how to test web apps for security flaws. Learn its testing categories, tools like ZAP, and SAST mapping.

Pen test software simulates attacks to find exploitable vulnerabilities. Learn the main tool categories and how continuous scanning complements manual tests.

Threat modeling for web apps identifies security risks before code ships. Learn STRIDE, PASTA, and LINDDUN frameworks for agile teams.

Vulnerability scanning software finds security flaws in code, dependencies, and infrastructure. Learn key features and how to choose a scanner.

A security vulnerability assessment identifies and prioritizes weaknesses in your applications. Learn the six-step process with automated scanning.

Compliance security scanning automates evidence collection for SOC 2, HIPAA, PCI DSS, and GDPR. Map scanning tools to controls and stay audit-ready.

Free online vulnerability scanners help you find security flaws without upfront cost. Learn what free scanners offer, their limitations, and when to upgrade.

Security audit of the most popular MCP servers reveals 50 vulnerabilities including 11 critical — from SSRF and command injection to authentication bypass and AWS credential exposure. These servers run with elevated privileges in developer environments worldwide.

Web security scanners detect vulnerabilities before attackers exploit them. Learn scanner types, how they work, and where code-level scanning fits in.

Learn what DAST is, how dynamic application security testing works, what vulnerabilities it catches, and how it compares to SAST and IAST.

Compare application security testing tools across SAST, DAST, SCA, and IAST. Build a testing stack that catches vulnerabilities without slowing CI/CD.
