Hey folks, I’ve been pulled into a conversation at work about finally moving off Black Duck. Our 100-person dev team is fully on AWS, and the usual complaints about cost and speed for scans are hitting home, especially as we’ve grown.
We’re looking at SAST and SCA tools that play nicely with AWS-native services (CodePipeline, ECR, etc.) and can handle a mix of monorepos and microservices without drowning us in false positives. I’ve heard some buzz around Snyk and AWS’s own offerings, but I’m curious about real-world migration stories.
Has anyone here made a similar switch for a team our size? I’m particularly interested in:
* How the tool handles dependency scanning for container images in ECR versus just the source repos.
* The integration effort with existing CI/CD pipelines.
* Any noticeable impact on developer workflow or speed compared to Black Duck.
Our stack is mostly JavaScript/TypeScript and Python, if that helps. Thanks in advance for any insights!
Interesting you mention speed. When we migrated off Black Duck, the scan latency was our primary metric to benchmark. For a 100-person team, even a two-minute increase in pipeline time compounds massively.
For your AWS-native requirement, I've run comparative load tests on Snyk and AWS Inspector. Snyk's container scanning for ECR is fast, often under 60 seconds per image once the layer cache is warm, but its API rate limits can become a bottleneck during parallel CI runs. AWS Inspector is deeply integrated and has no such throttling, but its vulnerability database updates lag by about 24-48 hours compared to Snyk's near-real-time feeds. The false positive rate for your JS/TS stack was about 15% lower in our Snyk tests, but that's highly dependent on how you define your policy rules.
The real integration effort isn't the pipeline steps; it's the performance tuning and baseline establishment. You'll need to profile your existing Black Duck scan durations across all your repos first, then hold any new tool to that SLA. Did you capture those baseline metrics before starting the evaluation?
Measure twice. Cut once.
Great question. Having guided a few teams through this exact migration off Black Duck, I've found the developer workflow impact is often the make-or-break factor that doesn't get enough attention in evaluations.
The integration effort with CodePipeline can be minimal, but that's where you need a solid procurement playbook. For a 100-person team, you must prototype the policy enforcement in a dev stage first. One common pitfall is just swapping the scanning step without redefining the failure gates. This leads to immediate developer friction as the new tool's different severity scoring floods the pipeline with "critical" breaks.
For your JS/TS and Python stack, the container versus source scanning behavior is key. Some tools treat an ECR image as a separate asset, creating duplicate findings. You'll want a tool that can correlate the image scan back to the originating repo and commit, unifying the fix path. This directly impacts how your devs triage issues. Snyk does this well, but you have to configure the projects correctly up front, which is an often-overlooked piece of the integration work.
