Checkmarx One is a paid web application-security platform focused on source-code analysis. It integrates with CI/CD workflows, scans pull requests, and supports IDE use so security checks can occur during development. Teams can define custom security rules and custom rules for their requirements, while automated fixes assist with remediation. The listed analysis target is source code. Pull-request scanning provides a way to examine proposed changes, and CI/CD integration connects checks with delivery processes. IDE support places analysis in developer tooling. Checkmarx One has no free plan, and pricing is available on request. The company was founded in 2006. Its web delivery model combines configurable security policies with automated assistance for addressing findings, without listing additional analysis targets or a free tier.

Nuclei is a free, open-source vulnerability scanner for applications, infrastructure, cloud platforms, and networks. It uses YAML templates to define checks, drawing on more than 6,500 community-contributed templates; users can also create custom templates. Bulk and parallel scans, multiple target formats, and inclusion and exclusion filters are supported. Modules cover HTTP, DNS, TCP, headless, JavaScript, code, and file scanning, and authentication options include HTTP basic authentication and JWT. Nuclei can run in CI/CD pipelines, including through GitHub Actions, and export SARIF results to GitHub Code Scanning. It is distributed under the MIT License and is primarily a standalone CLI tool, with installation options including Go, Homebrew, Docker, GitHub, downloadable binaries, and Helm. It is actively developed, but has no LTS or stable version, so updates may bring breaking changes. Some templates can fuzz or take actions that risk denial of service; these are tagged and excluded from default scans. The tool is intended for security engineers, analysts, red teams, DevOps teams, bug bounty hunters, and penetration testers.
