CSSLP® - Certified Secure Software Lifecycle Professional

The Application Security Certification from the Industry Leader

With the CSSLP certification from (ISC)², your application security competency within the software development lifecycle (SDLC) will be validated. You'll not only be seen as an industry leader in application security, but also as a leader within your organization, a status you'll rightly deserve because you'll have proven your proficiency in:

  • Developing an application security program in your organization
  • Reducing production costs, application vulnerabilities and delivery delays
  • Enhancing the credibility of your organization and its development team
  • Reducing loss of revenue and reputation due to a breach resulting from insecure software


Application vulnerabilities affect our everyday lives. In order to make the cyber world a safer place, we must ensure web application security is a priority. It's no wonder that application vulnerabilities were ranked the #1 threat to information security professionals in the 2013 (ISC)² Global Information Security Workforce Study.

Who is the CSSLP credential for?

The Certified Secure Software Lifecycle Professional (CSSLP) is for everyone involved in the SDLC with at least 4 years of cumulative paid full-time work experience in 1 or more of the 8 domains of the CSSLP CBK. Download a CSSLP brochure.
