Safety CLI is a command-line tool for scanning Python project dependencies against a proprietary vulnerability database to detect security issues in open-source packages. It scans dependency trees across multiple stages of the software development lifecycle, including local development environments, CI/CD pipelines, and production environments. The tool identifies vulnerable packages and provides remediation guidance, including specific version upgrade recommendations. Key capabilities include: - Detection of vulnerabilities across Python requirements files and environments - Policy-based scanning, with scan policies fetched from the Safety Platform - Identification of vulnerabilities with unique IDs and detailed technical advisories - Suggested fixes with verified upgrade paths to resolve detected vulnerabilities - Support for ignoring specific vulnerabilities based on defined policies - Integration with the Safety Platform for viewing and managing scan results Safety CLI uses a proprietary security intelligence database, maintained by a team of cybersecurity researchers who monitor open-source package releases and code changes. The tool claims to detect more vulnerabilities than public databases such as the National Vulnerability Database (NVD) by incorporating AI-assisted analysis of vulnerability signals. Results include the number of dependencies tested, vulnerabilities found, vulnerabilities ignored per policy, and fixes suggested. Scan output links to the Safety Platform for detailed result viewing.
