The shared responsibility line moves: you no longer patch the OS, but you are fully on the hook for function code, dependencies, IAM permissions, event triggers, and secrets. The solutions here close the gaps that traditional agents and host-based scanners cannot reach, because there is no host to put an agent on. Security teams running cloud-native or event-driven architectures use this category to find vulnerable dependencies, over-permissioned roles, and runtime abuse before an attacker chains them into something worse. 1 commercial products · [What is Serverless Security?](https://cybersectools.com/glossary/serverless-security) ## Featured on CybersecTools Paid placement: Featured vendors pay for a plan and show first.

Serverless security is the protection of function-as-a-service workloads such as AWS Lambda, Azure Functions, and Google Cloud Functions. Because the cloud provider manages the underlying servers and runtime, your responsibility shifts to the function code, its third-party dependencies, IAM permissions, event-source configuration, and any secrets it touches. The goal is to catch vulnerable code, excessive privileges, and runtime abuse without a host to install an agent on. ### How is serverless security different from container or CWPP security? Container and broader cloud workload protection (CWPP) solutions usually assume a long-running host or node where you can deploy an agent and watch processes. Serverless functions are ephemeral and run on infrastructure you cannot touch, so the same approach does not apply. Serverless-focused solutions lean on static analysis of code and dependencies, IAM and configuration checks, and lightweight in-function runtime defenses instead of node-level agents. ### What should serverless security solutions actually cover? Look for dependency and code vulnerability scanning, least-privilege analysis of the function's execution role, configuration checks on triggers and environment variables, and secrets detection. Stronger options add runtime protection that blocks unexpected outbound calls, file writes, or child processes during execution. Coverage across AWS, Azure, and Google Cloud matters if your functions are not all in one place. ### How do I choose a serverless security solution? Start with where your functions run and which platforms a solution genuinely supports, not just the names listed on a website. Decide whether you need shift-left scanning in CI, runtime defense in production, or both. Weigh how it handles IAM right-sizing, how noisy its findings are, and whether it fits your existing pipeline and cloud security posture solutions rather than adding a disconnected silo. ### Do I need a dedicated serverless solution or does my cloud security platform cover it? Many CNAPP and cloud security posture platforms now include some serverless coverage, which may be enough if your function footprint is small or low-risk. Dedicated or runtime-focused solutions tend to go deeper on in-function behavior, dependency analysis, and least-privilege tuning. The honest answer depends on how much of your business logic runs in functions and how much blast radius those functions carry. --- Source: https://cybersectools.com/categories/serverless-security For AI agents: every CybersecTools shortlist is listed at https://cybersectools.com/shortlists.md.
