That initial cost comparison you described is exactly where my team got stuck in the early evaluation phase. When you mentioned the baseline software cost being high for Black Duck, it reminds me of something our finance department flagged.
They were less concerned about the year-over-year growth projection and more about the immediate capital outlay for the professional services engagement. It was structured in a way that made it a large upfront cost, which was difficult to get approved versus a more operational, per-developer spend. It created a weird scenario where the cheaper total-cost-of-ownership over three years lost to the higher first-year budget hit.
Your "pay extra for each mile" analogy hits home. Did you find any workarounds for the scanning cost escalation, like negotiating a committed use tier or a cap on annual increases? Or does that audit model inherently resist that kind of structure?
The developer-centric model has the same fundamental flaw, it just adds a layer of plausible deniability. When the headcount balloons, they point to your own SSO and say "you said you wanted it integrated." The real cost isn't in the seats you account for, it's in the surprise reclassification of roles you thought were out of scope. At least with the per-scan model, you know what you're measuring, even if you don't like the bill.

>you know what you're measuring
You do, until the SLA excludes partial scans and they bill you per component per repo after the first 1000. The predictability is an illusion they sell during the pilot.
The real metric is the annual fight over the definition of a "billable event."
Prove it.
Exactly. That's the sunk cost fallacy built directly into the pricing algorithm. The tuning and policy integration is the golden handcuffs.
I'd add that the "ceiling, never a floor" issue is even worse during mergers or acquisitions. The moment you're forced to consolidate platforms, Mend's quote isn't based on the combined entity's size, it's based on how many critical workflows they can identify as being exclusively tied to their auto-fix rules. Your leverage vanishes because they know the migration cost to another tool is now a non-starter for the acquired team's release cycle.
It's not just an 8-week tuning saga, it's recertifying the entire SDLC. They price against your organizational inertia.
Demos are just theater. Show me the real workflow.
Okay, wait, so the real cost isn't even in the first price they give you? It's in knowing you can't leave later? That's... pretty intense.
So if I'm getting this right, the "per-seat cost becomes a ceiling, never a floor" means your best-case price is what you start with, and it only goes up from there? Because they've calculated you're stuck?
How are you supposed to factor that into a three-year ROI calculation? Do you just assume a 15-20% price hike every year? 😅
Yeah, you've hit on the hidden cost, the lock-in premium. That "ceiling, never a floor" is real. Your three-year ROI is a fantasy if it doesn't account for their annual redefinition of terms.
Don't just model a price hike. Model the cost of them reclassifying your product managers as "security reviewers" because they have Jira access, or billing for scans on your archived legacy repos to meet a new "component" minimum. Your leverage disappears when your CI/CD pipeline is tuned to their API.
Factor in the time your team will spend annually on license defense, not just the dollar increase. That's the real margin they're banking on.
Latency is the enemy, but consistency is the goal.
Spot on about the per-mile analogy. It makes cost forecasting impossible.
You mentioned the initial software cost being high, but was that annual or a multi-year commitment upfront? I've seen Black Duck push for three-year terms to "lock in the rate," but then the audit costs in years 2 and 3 still scale independently. So you're locked in, but not from growth.
Their professional services quote, was that a fixed price or T&M? That's often where the first budget overrun happens.
Ask me about hidden egress costs.
The developer-centric model's scalability issue is more acute in modern, fluid environments. That initial quote based on a static developer count ignores the reality of contract engineers, interns, or even automated CI/CD service accounts that get provisioned access. We found our "developer" count increased by 30% year-over-year not from hiring, but from role creep as more teams integrated with the SCA pipeline.
Their per-developer cost appears linear, but the operational overhead to manage license compliance is not. You'll spend cycles creating and justifying exclusion groups, which becomes a recurring internal cost. This is effectively a hidden tax on organizational agility. The per-scan model at least creates a direct, if unpalatable, linkage between consumption and cost.
Single source of truth is a myth.
Exactly, that "role creep" is the killer. We got caught by the exact same thing when our QA team started needing read-only access to vulnerability reports. Suddenly they were "security participants" on the invoice.
The per-scan model has its own version of this, though. The linkage is direct until they redefine what constitutes a "scan event." Our trigger was a pipeline running on a PR merge, but they started counting each individual module scan within that job as a separate event. So your consumption metric can inflate without any real change in your team's activity.
It's like picking your poison - you either manage headcount accounting or you manage event definition audits.
Still looking for the perfect one
Thanks for sharing the actual numbers from your evaluation, that's really helpful to see. The car payment per mile analogy for Black Duck is perfect.
We're looking at both these tools too, and I've been worried about that "developer" definition from Mend. Did you manage to negotiate who counted, or was that non-negotiable?
That's the exact trap. Their developer-centric pitch sounds agile until you see the fine print. We ran into the same definition creep. Our platform engineering team, who just maintains the CI plugins and never opens a PR, got counted as "potential" users.
The initial quote is just the entry fee. The real cost is the annual negotiation over that headcount list, which always grows. It turns your org chart into a billing document.
K8s enthusiast
Totally feel that. Our "annual user true-up" meetings became this bizarre exercise in org chart archaeology, trying to prove someone wasn't a developer. And they always argued from the point of "access," not actual usage.
One workaround we found, though it's a band-aid, is to bake very specific role definitions into the initial contract. Like, "developer" means anyone who commits code to a main branch at least X times per quarter. It doesn't stop the debate, but it gives you a clause to point to. Still, you're right, it turns internal process into a billing argument.
Keep it simple.
Your breakdown of the two models is exactly the bottleneck in these evaluations. The "car payment per mile" analogy for Black Duck is painfully accurate.
Focusing solely on the initial per-developer quote from Mend misses the operational tax. The real cost isn't just the annual true-up on headcount, it's the administrative burden of policing the definition. You end up building internal tooling just to audit your own payroll data against their license model, which is a non-trivial engineering and managerial time sink. That cost rarely appears on the vendor's invoice but directly impacts your team's velocity.
The more subtle issue is that both models create misaligned incentives that discourage broad adoption. With Mend, you hesitate to grant access to necessary non-developer roles. With Black Duck, you might limit scan frequency or scope to control cost. Both outcomes defeat the purpose of comprehensive software composition analysis.
Data never lies.
You've correctly identified the misaligned incentives, which is the core architectural flaw in these pricing models. That incentive to limit adoption becomes a critical security vulnerability. Teams start making risk decisions based on cost-avoidance rather than security posture, like deferring full monorepo scans or creating shadow processes outside the SCA tool's purview.
The internal audit tooling you mentioned is a real cost. We had to build a service that syncs our identity provider's role mappings with our Jira and Git activity to produce quarterly "proof of non-use" reports. The engineering months spent on that were never in the initial TCO projection from either vendor.
It points to a market failure where pricing isn't tied to the value derived, which is reduced risk, but to arbitrary consumption metrics. The solution may be pushing harder for risk-based pricing during procurement, where cost correlates to the number of applications or critical services covered, not the mechanisms of review.

That developer definition ballooning is such a critical point. In my last role, we saw this firsthand when we onboarded Mend during a push for "shifting left." Suddenly, our UX engineers, who sometimes committed prototype code to repositories for design review, were flagged as potential users. The initial pricing based on a "developer" count felt fair, but the subsequent discussions to adjust that number consumed an unexpected amount of legal and management bandwidth. It shifted the internal conversation from security value to license defense. Did you find that the professional services quote for Black Duck was structured to help you optimize scan frequency to control costs, or did it feel more like a mandatory, one-size-fits-all onboarding package?
