Direct answer
Penetration testing proves what can be exploited today. A Secure SDLC review improves how you build so issues stop recurring. An architecture security review challenges design assumptions before they become expensive production debt. Most product teams eventually need more than one — sequenced to the decision they need to make now.
Quick comparison
- Penetration testing — point-in-time attack simulation; best for release assurance and evidence-backed findings.
- Secure SDLC review — process and tooling maturity; best when the same issue classes keep returning.
- Architecture security review — design and trust boundaries; best before major builds or platform changes.
- AI SDLC review — product AI features plus AI coding tools; best when LLMs or coding assistants change your risk surface.
Which should you buy first?
If a customer or board needs assurance on a live system, start with a pen test. If you are designing a new multi-tenant platform, start with architecture review. If engineering velocity is high and security feels bolted on, start with Secure SDLC. If AI features or coding assistants are rolling out, add an AI SDLC review.
Can these run together?
Yes. A common sequence is architecture review → build with secure-by-design practices → pen test before major launch → SDLC review to lock in gates. Overlap is fine when scopes are explicit in the statement of work.
