Protect People From Supply Chain Attacks at the Source
Real-Time Protection & Zero Friction
Every package installation request is analyzed before reaching public repositories. Malicious, vulnerable, and policy-violating packages are automatically blocked before they can enter your systems, preventing rather than just detecting threats.
Install once at the OS or container level, protect everywhere. Developers continue using standard package manager commands (like 'pip install') with no new workflows or tools to learn. Security happens transparently in the background.

Frequently Asked Questions
Where can I read technical documentation?
Full technical documentation is available at https://docs.safetycli.com. If you require further guidance or support, please contact us at support@safetycli.com.
Does Safety work with Github?
Yes! Safety is built to work with most commonly-used development systems, including GitHub, GitLab, Docker, BitBucket, and more. For GitHub specifically, Safety has a GitHub Action that makes implementing Safety scans into your CI/CD workflow a breeze.
Why is scanning in CI/CD alone not advised?
Attack vectors like typosquatting mean that a single typo in an install command can expose developers to malicious packages or critical, exploitable vulnerabilities. For example, this malicious package was downloaded over 1,300 times. Even though PyPI took it down, those machines were still infected until the package was detected and removed. This is why scanning in CI/CD is too late: Development machines must be protected from the installation of such packages at the source.
Safety is designed to provide end-to-end protection against vulnerable, malicious, or non-compliant open-source packages. Whenever a developer tries to install an open-source library, the request is routed through Safety and either allowed or blocked based on the policy you have applied. This ensures only packages that meet your security requirements are installed.
Why is CVSS Not Enough for Assessing Vulnerabilities?
CVSS is useful for measuring vulnerability severity but lacks critical context like exploitability, reachability, and real-world impact. High scores can lead to alert fatigue, while lower-scored vulnerabilities may still pose serious risks.
Safety goes beyond CVSS by manually verifying vulnerabilities and incorporating additional intelligence and reachability analysis, ensuring teams prioritize real threats and reduce noise. Please read this article for more information.
How much does Safety cost?
We have plans that cater to teams of all sizes, from solo developers to large enterprises.
Our free plan is ideal for solo developers working on non-commercial projects, while our Team and Enterprise plans are built for teams developing commercial applications and who require the most comprehensive supply chain security available.
How does the Free plan differ from paid plans?
Our free-for-life plan is intended for solo developers working on non-commercial projects. This plan is limited to a single developer seat and uses open-source vulnerability data when performing scans. Our paid plans are intended for teams working on projects and leverage Safety’s full proprietary vulnerability database when performing scans. Our vulnerability data contains data roughly 4x more vulnerabilities and malicious packages than other providers, meaning our paid plans offer unparalleled levels of security.
