CSSLP — Certified Secure Software Lifecycle Professional
ISC2's software security certification covering the full secure software development lifecycle — from security requirements through secure design, coding, testing, deployment, and operations. DoD 8140 approved and the primary credential for application security professionals operating at a program or architecture level rather than hands-on testing. Requires four years of paid SDLC experience. The theory-heavy format means it validates process and management knowledge rather than technical application security skill. Most valuable for application security managers, architects, and program leads in organizations with formal SDLC processes — less relevant for hands-on penetration testers.
