PTaaS vs Traditional Pentest Consulting: Cost Shape, Coverage, and When to Choose Which (2026)
Cobalt explains its credit model on its own page and consultancies explain their engagements on theirs. This page puts the two shapes side by side, using only what the vendors publish.
Same annual spend. PTaaS buys continuous coverage (shallower but current). SOW buys deep one-time methodology attestation. Neither is universally better; the right choice depends on your risk model.

When PTaaS Wins vs When SOW Wins
- You ship code continuously and need up-to-date security testing
- You want to accumulate credits and test on your own schedule
- You have multiple small apps rather than one large one
- You want a platform for tracking findings across engagements
- You plan to test 2+ times per year (platform fee amortises)
- You need a single clean attestation report for a compliance audit
- Your architecture is highly complex and needs custom methodology
- You need specific certifications (CREST, CHECK, FedRAMP)
- Your target is hardware or embedded (IOActive lists embedded devices)
- You test once per year and don't want a platform commitment
12-Month TCO Worked Example: $50k Budget
- One 3-4 week engagement with a specialist consultancy
- Web + API + cloud, 60-80 endpoints
- Full technical report + executive brief
- Retest included (90-day window)
- Coverage: 4 weeks per year, deep methodology
- Annual package of testing credits on a platform
- Tester hours spread across the year
- Multiple smaller tests (new features, quarterly)
- Reports per test, continuous visibility
- Coverage: quarterly, shallower per engagement
Neither option is wrong. The SOW buys depth once; the credit programme buys breadth continuously. How many hours $50k buys on a platform depends on a quoted credit price, which Cobalt, for one, does not publish. Match the choice to your actual security risk model.
For compliance-driven pentest requirements (SOC 2, PCI DSS 11.4, ISO 27001, HIPAA), the scope and deliverables each framework expects are covered on what’s included in a pentest.
