How I Migrated from GitHub Advanced Security (GHAS) to Snyk Across Multiple Repositories

I recently worked on migrating our security setup from GitHub Advanced Security (GHAS) to Snyk across multiple repositories.

This wasn’t just about switching tools. The main focus was to make sure security checks stayed consistent in our CI/CD pipelines without affecting developer workflows.

Why we moved:

• Needed better visibility across projects
• Wanted a more flexible setup for SAST and dependency scanning
• Improve how developers get feedback during PRs

What I worked on:

• Disabled GHAS features gradually across repos
• Integrated Snyk into GitHub Actions pipelines
• Set up scans for code, dependencies, and container images
• Configured scans on pull requests and commits

Challenges I faced:

• Making sure nothing was missed during migration
• Handling pipeline failures caused by new security checks
• Getting teams comfortable with the new setup

How I handled it:

• Did the migration step by step instead of all at once
• Tuned the pipelines to reduce noise from false positives
• Shared simple guidance with developers on how to fix issues

Result:

• Better visibility into vulnerabilities
• Faster feedback during development
• More consistent security checks across repositories

Overall, it was a good experience working on improving how security fits into the development workflow without slowing things down.
