Alright, let's cut through the marketing fog. I'm looking at our upcoming AppSec stack renewal and the usual suspects are on the table. We've had Checkmarx (SAST) for years, and the security team is now pushing hard for Black Duck (SCA) from the same parent company. The sales narrative is, predictably, one of beautiful synergy and seamless integration.
My experience tells me that when two expensive tools from the same vendor umbrella are sold together, the overlap is often exaggerated and the TCO balloons under the guise of "platformization." I need to separate the slideware from reality.
So, for those of you in the trenches actually *running* both in production across a sizable, polyglot codebase:
* Where is the genuine workflow integration, and where is it just a shared login screen? Does a vulnerability found by Black Duck genuinely trace through to the Checkmarx findings in the IDE or CI pipeline, or am I just toggling between two different portals with different taxonomies?
* How much **actual duplication of effort** are you seeing? Specifically, does Checkmarx's limited SCA component detection now just become noisy, redundant background noise since Black Duck is the designated source of truth? Are you effectively paying twice to scan the same open-source libraries?
* On the operational side, what's the resource hit? Are we talking about two independent agents chewing through pipeline minutes, two separate sets of tuning to reduce false positives, and two different reporting streams that my app teams have to reconcile?
* Most importantly, from a procurement and vendor management standpoint: did bundling them give you meaningful leverage on the total contract value, or did it just lock you deeper into a single vendor's ecosystem with its associated annual "business review" and premium uplift?
I'm particularly skeptical of the "unified risk view" promise. In my world, that usually means a dashboard that requires another six-figure professional services engagement to make functional. Concrete experiences on operational overhead, true complementarity, and negotiation points are what I'm after. The glossies are already on my desk.

Ran both for about two years on a 500+ repo estate. The integration is mostly theater.
>Where is the genuine workflow integration, and where is it just a shared login screen
It's a shared login and a unified dashboard that repackages separate findings. The "trace through" they promise is weak. Black Duck finds a vulnerable lib, but linking that to the exact line of code in Checkmarx where it's called? That's manual work. In CI, they're just two different plugins that fail the build independently.
Checkmarx's SCA component detection is absolutely redundant noise once Black Duck is in place. You have to actively turn it off in the Checkmarx scan configs, which they don't tell you upfront. Otherwise, you get duplicate, often conflicting, severity ratings for the same CVE. Triage effort doubles.
They're complementary in function (SAST vs SCA), but the "synergy" is a tax. You're maintaining two scan engines, two result databases, and two sets of false positives. The real value is forcing a single procurement contract, not a better security workflow.

Your experience mirrors what I've seen in several large scale integrations. The disconnect between the marketing narrative of traceability and the actual triage workflow is significant.
You're right about disabling Checkmarx's component detection, but it's worth checking if your pipeline is using the "ScaResolver" configuration flag. Even with that, the correlation is typically at the file level, not the line of code. The promised "single pane of glass" consolidates alerts but doesn't unify the underlying data models, so you're still reconciling two separate vulnerability objects with different metadata.
The operational burden you mention, two scan engines and two result databases, is the hidden cost. It often necessitates building custom middleware to deduplicate and normalize findings before they hit the ticketing system, which defeats the purpose of buying an integrated platform.
