In their own words
OWASP ZAP
OWASP ZAP is a web application scanner and proxy for security testing. Its tools include active and passive scanning, a spider, alerts, and scan policies. ZAP’s Automation Framework uses YAML plans to coordinate jobs such as scanning, spidering, API imports, and report generation. It can import OpenAPI, GraphQL, SOAP, and Postman definitions through jobs or add-ons. GitHub Actions are available for baseline, full, and API scans via Docker-packaged scans, and the project publishes Docker images, including a minimal image for CI. Add-ons come from an online Marketplace and are generally installed or removed without restarting ZAP. The software is free and open source, with a free plan at free. It supports Linux, macOS, Windows, API use, and self-hosted deployment. Windows and Linux installers require Java 17 or later; the macOS installer includes Java 17. ZAP says it can support only its latest full release, and current releases are unsigned, though checksums are provided.
ZeroThreat
ZeroThreat is an AI-powered penetration-testing platform for web applications and APIs, accessible through web and API. It continuously discovers, exploits, and validates vulnerabilities, with findings backed by reproducible request-and-response evidence and exact payloads. Web testing supports authenticated workflows, including SSO, MFA, and role-based access, as well as rendering for React, Vue, and Angular single-page apps. API testing covers REST, GraphQL, SOAP, and gRPC, including internal APIs, shadow endpoints, BOLA, and BFLA. ZeroThreat says it detects more than 130,000 vulnerabilities, spanning OWASP, CWE/SANS, Nuclei, and monthly updated CVE intelligence. Integrations include CI/CD, project-management, and messaging tools, connected through native connectors, APIs, or webhooks. On-premises deployment is listed as air-gap ready. The free plan provides five sign-up scan credits valid for 15 days, then one scan credit per month for one target. Professional costs $100 a month; Pay Per Scan costs $125, paid once.
