Securing cloud functions is challenging because serverless workloads are small, short‑lived, and difficult to monitor, with dependencies that are often hard to fully identify. Their ephemeral nature allows security issues to spread as functions are reused across development. It is essential to secure functions before deployment and to protect them at runtime with mechanisms purpose‑built for serverless environments. Given the speed and scale at which functions operate, organizations need comprehensive visibility and enforcement to detect malicious activity and maintain strong security across rapidly changing cloud native applications.
