Hey everyone,
I've been helping a few teams set up Wiz for their cloud environments, and there's a recurring question popping up: how well does it handle the serverless world, specifically scanning AWS Lambda functions? While Wiz does a solid job with containers and VMs, its depth for serverless always feels a bit secondary.
For teams with heavy Lambda use, the feedback I'm hearing is that the scanning can be a bit shallow—it often catches the obvious IAM misconfigurations or publicly exposed functions, but doesn't always dive deep into the actual function code, dependencies, or runtime-specific risks. The ephemeral nature of serverless seems to trip up some of the traditional agentless approaches.
So I'm curious: what are you all using as alternatives or supplements when Wiz isn't cutting it for your serverless security? I'm looking for tools that can:
* Perform deeper code and dependency analysis within the Lambda deployment package.
* Integrate into CI/CD pipelines for functions, not just the infrastructure.
* Handle the rapid scaling and short lifespans without creating alert fatigue.
I've heard names like Snyk, Prisma Cloud (formerly Twistlock), and even some AWS-native tools like Inspector thrown around. Real-world experiences with these, especially on cost and integration complexity, would be super helpful.

Keep it civil, keep it real.
Your observation about traditional agentless scanning struggling with ephemeral assets is spot on. I've run side by side tests on several platforms to address this exact gap.
For deep package and code analysis, Snyk Code and Snyk Open Source integrated directly into the CI/CD pipeline have provided the most granular findings, catching issues in third party dependencies that infrastructure scanners miss. However, its posture management for the serverless function configuration itself is weaker.
Prisma Cloud's serverless module does a better job at correlating code risks with runtime configuration, but the deployment model can be heavy. The most effective setup I've seen uses a specialized tool like Snyk for the code layer, paired with AWS Config and custom rules for the IAM and trigger posture, feeding into a consolidated dashboard. This separates the concerns of static analysis from dynamic runtime posture.
Have you considered this bifurcated approach, or is the team insistent on a single pane of glass?
You're right about the scanning depth, and the CI/CD ask is key. The Wiz API approach can work for some, but it's a hack.
Most teams I've seen go multi-tool. Snyk for the code and deps, but then you still need something to watch the live config drift. I've had better luck with AWS-native tools than adding another heavyweight platform.
Consider splitting the problem:
* GuardDuty for runtime threats, tuned for Lambda.
* A few custom Config rules for IAM and network exposure, which Wiz often misses.
* Snyk or Checkov in the pipeline for the package itself.
It adds overhead, but the all-in-one platforms still treat serverless as a second class citizen.
Your CRM is lying to you.
