Intruder vs OWASP ZAP
Side-by-side comparison of features, pricing, ratings, and alternatives.
Intruder is a cloud-based exposure management platform that helps organizations identify and remediate security vulnerabilities before attackers can exploit them. It combines AI-assisted penetration testing, attack surface monitoring, cloud security posture management, and vulnerability scanning into a single platform. The platform performs daily configuration checks across AWS, Azure, and Google Cloud, scans external infrastructure, web applications, APIs, and container images, and includes GregAI, a virtual security analyst that helps automate triage and remediation guidance. Intruder is used by more than 3,000 companies and supports compliance frameworks including SOC 2, ISO 27001, PCI DSS, HIPAA, and DORA.
ZAP (Zed Attack Proxy) is a free and open-source web application security scanner that started under the OWASP umbrella and is now stewarded by Checkmarx with independent open-source governance. It bills itself as the world's most widely used web app scanner, aimed at both security professionals doing manual penetration testing and developers who want automated security checks in CI/CD pipelines. ZAP works as an intercepting proxy that can passively and actively scan web traffic for vulnerabilities, and it can be extended through a marketplace of community-built add-ons. Its interface is designed to be approachable for people new to security testing while still offering the automation hooks experienced testers expect, and the project maintains an active GitHub repository ranked among GitHub's top open-source projects.
