Detecting and Preventing Secret Leaks in Code

A practical guide to secrets detection, management, and keeping sensitive information out of your codebase.

The growing number of secret leaks highlights the challenge. With developers pushing code faster and the attack surface widening, secrets are increasingly exposed, providing tempting targets for bad actors.

In 2024, GitHub developers alone used secret scanning to detect over 39 million secret leaks, a startling reminder of the need for a robust strategy to secure sensitive information. The consequences of leaked secrets are serious, often leading to breaches of proprietary, financial, or customer data.

In this guide, you'll discover:

  • The current landscape of secret security and why leaks are on the rise.

  • The principles of secrets detection and management — from identifying leaks early to preventing unauthorized access.

  • Considerations for securing secrets in your code without sacrificing speed or developer productivity.
