Intercept Security Scans with Vulnerability Webhooks

Security scanning provides an opportunity to target, track, and trace vulnerabilities introduced to your packages as soon as Cloudsmith has received a complete package upload. However what happens when you want to intercept the results of a scan immediately. An early warning can make a difference when distributing vulnerable packages to hundreds, thousands, or even millions of developers, devices, or systems globally.


Top vulnerability assessment and management best practices

By implementing these vulnerability assessment and vulnerability management best practices you will reduce the attack surface of your infrastructure. We’re human, and many things we build aren’t perfect. That’s why we take our cars for a periodic inspection, or why we have organizations certifying that products are safe to use. Software is no different.
