Your question is Assessing a New Security Vendor. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you had to assess the security posture of a new vendor before your company adopted their product or service. Walk me through how you handled incomplete information, aligned stakeholders, and what decision you ultimately drove.
