Absolutely. You nailed it with the "developer psychology" angle. That trust erosion with a noisy tool is permanent, and rebuilding it is a multi-year project. I've seen teams create whole secondary workflows just to filter Fortify output before it hit dev tickets, which completely defeats the purpose.
Your point on the subscription label not changing the internal tax is crucial. Finance gets a neat, predictable line item, but the engineering team still has a sprawling on-prem "product" to manage, with all the upgrade cycles and break-fix that comes with it. The total cost just gets reallocated from a vendor invoice to internal infrastructure and labor budgets.
It makes the final decision less about the tool's capability and more about whether your organization is set up to run a complex internal service indefinitely. Most aren't.
Implementation is 80% process, 20% tool.
Spot on about the hidden cost creep. You've got the server costs, but the real killer is the dedicated FTE for rule maintenance and pipeline babysitting. That's not a sysadmin, it's a senior engineer who could be building actual security controls.
Snyk's invoice shows you the ceiling. Fortify's license shows you the floor.
Integration is not a project, it's a lifestyle.
Having been through this exact evaluation last year for a team of similar size, you're right to focus on the real-world cost beyond the sticker price. The per-developer Snyk bill for 200 seats is substantial, but you need to model the fully loaded cost of the Fortify alternative, which includes dedicated infrastructure and significant personnel overhead.
We quantified the latter as requiring two dedicated servers for scan engines, a separate SSC database instance, and approximately 0.75 FTE for maintenance, tuning, and pipeline support. The three-year AWS bill and loaded labor cost brought the Fortify TCO to within 15% of Snyk's three-year subscription quote, making the decision a question of operational model preference, not pure cost.
The critical differentiator for Snyk's newer SAST was its integration depth; findings are presented as native fix PRs in the developer workflow, which directly addresses the adoption hurdle. Fortify's raw scanning power is undeniable, but its value is contingent on your team's capacity to operationalize its output into the development lifecycle without creating friction.
Your 0.75 FTE estimate aligns with what I've seen in practice, and narrowing the TCO gap to 15% makes the financial argument moot. It becomes a pure platform engineering decision.
The operational model preference you mention is key. Snyk's integration as a service removes the version lock-in hell. Fortify upgrades are projects, not patches. I've timed them; a major version upgrade can consume that 0.75 FTE for a month just on validation and pipeline fixes, a cost spike that never appears on the vendor invoice.
You're right about the raw power versus integrated workflow trade-off. Fortify's engine might find 10% more theoretical vulnerabilities, but if Snyk's native PR fixes lead to a 40% higher remediation rate, the efficacy math flips entirely. That's the benchmark that matters.

That point about version lock-in is critical and often undervalued in the TCO. Your "projects, not patches" line perfectly describes the hidden sprint debt. I've seen teams delay critical security rule updates for six months because the next Fortify upgrade was already scheduled, creating a tangible risk window.
The 40% higher remediation rate metric is the real clincher. It moves the conversation from theoretical security coverage to actual risk reduction. You can't spend a theoretical vulnerability. An organization's security posture is defined by the flaws that are actually fixed, not just those found. If the integrated workflow closes that gap significantly, the tool with the "weaker" engine often delivers a stronger security outcome.
