Case Study: Reddit achieves automated, scalable application security across 1,000+ repositories with Snyk

How Reddit used Snyk’s API to automate & scale application security

Reddit, a major social media platform, needed to scale application security across a rapidly growing and diverse codebase while operating with a very small AppSec team. The company adopted the Snyk platform—specifically leveraging the Snyk API and its Python client—to avoid manual UI work across more than 1,000 repositories and to integrate security into developer workflows.

Using Snyk’s API and the pysnyk wrapper, Reddit automated vulnerability scanning, built a GitHub Enterprise integration (snyk-sync) that runs weekly to synchronize repos, and enforced PR checks that fail on new vulnerabilities—shifting remediation to developers. The Snyk-powered rollout covered the majority of the codebase in a couple of weeks, delivered scalable open-source dependency scanning across 1,000+ repos, reduced operational burden, and lowered total cost of ownership.
