Vendor review
Vendor security review checklist
A vendor security review does not always need to start with a long questionnaire. A useful first step is to review what the vendor domain exposes publicly and whether the company appears organized, maintained, and ready for scrutiny.
External checks worth reviewing first
- Domain and DNS posture
- Email security signals such as SPF, DKIM, and DMARC
- SSL and certificate health
- Visible services and ports
- Public subdomains or legacy assets
- Basic browser-side controls such as security headers
What these signals tell you
No single signal proves whether a vendor is secure. Together, they help you understand whether the vendor looks well maintained, whether obvious gaps are visible, and whether deeper follow-up questions are likely to be needed.
Questions to ask after the initial scan
- Who owns public-facing infrastructure and domain changes?
- How often are exposed services and legacy assets reviewed?
- Is there a process for handling customer security questions?
- What is the escalation path for high-risk findings?
Why this is useful before procurement deepens
Early external review helps teams prioritize attention. It can reduce wasted time, surface obvious issues sooner, and make formal procurement conversations more efficient.
