The ISC2 Certified Secure Software Lifecycle Professional (CSSLP) is the world’s leading certification for software development and security professionals who need to incorporate security practices into every phase of the software development lifecycle (SDLC). The CSSLP validates advanced technical knowledge and skills in authentication, authorization, and auditing throughout the entire software lifecycle — from design and requirements through implementation, testing, deployment, and supply chain management. Accredited to ISO/IEC 17024 by ANAB and recognized under the U.S. Department of Defense (DoD 8140) framework, the CSSLP is trusted globally by employers who need to know their software teams can build and maintain secure applications from the ground up, not just patch vulnerabilities after the fact.
Audience Profile
- Software Architects and Software Engineers responsible for designing secure systems
- Software Developers building security into code from the earliest stages
- Application Security Specialists and Penetration Testers
