Zero day risk hides in plain sight inside the procurement process

Every dependency, vendor API, and third-party service can be a silent entry point. When you sign a contract or integrate a library, you inherit every flaw in its code. If one of those flaws is undiscovered—a zero day—it can become your weakest link.

The procurement process is more than price negotiation. It is a gate. Allowing unsafe components through that gate makes every downstream system vulnerable. Security teams often focus on perimeter defenses, but modern attacks move through supply chains. A single zero day in vendor software can bypass firewalls, endpoint security, and even cloud controls.

Zero day risk management starts before you agree to buy or integrate. That means continuous vendor assessment, software composition analysis, and contractual requirements for disclosure. Check version histories. Demand patch timelines. Monitor threat intelligence for chatter about your suppliers. If a vendor cannot give clear answers about their security posture or update policies, the risk is higher than the reward.

Procurement teams and engineers must work together. Automated scanning should flag risky components before they reach staging. Every dependency added to your systems must pass security review. Build a process where no code enters production without full visibility into its origin, age, and known vulnerabilities.

Zero day exploitation works fast. Your defenses must work faster. By treating procurement as a security checkpoint, not just a business workflow, you close the gaps attackers want to exploit. That is how you cut zero day risk before it spreads through the chain.
