Secure development lifecycle (SDLC): how to answer it in a security questionnaire

Usually asked as: “Describe your secure development lifecycle (SDLC).”

Updated

What the buyer is really asking

Buyers want to see security built into how you ship, not bolted on at the end. List the actual steps: design review, code review, automated testing, and controlled deployment.

Other ways buyers ask it

Every one of these wants the same answer:

  • “Describe your secure software development lifecycle.”
  • “Do you follow a secure SDLC framework?”
  • “How is security integrated into development?”

Evidence to have ready

  • An SDLC or change management policy
  • Branch protection and required review settings
  • CI pipeline configuration showing security checks

How Tyrvar answers this

Tyrvar treats every wording above as one question. You write the answer once, attach the evidence, and revisit it when your setup changes. Each buyer gets that approved answer no matter how their questionnaire words it. If you have not answered it yet, Tyrvar flags the question for you and does not make something up. Try it on your own questionnaire.
