The vulnerability disclosure policy requirement

The vulnerability disclosure policy requirement mandates that manufacturers of connectable products provide a clear, public-facing mechanism for security researchers and users to report vulnerabilities. The goal is to ensure that security flaws are identified and remediated before they can be exploited at scale.

What it means

In practice, this requirement means you cannot expect vulnerabilities to stay hidden; instead, you must invite the security community to find them and report them to you securely. It shifts the responsibility from "security through obscurity" to a proactive management cycle of discovery, reporting, and patching.

The scope extends beyond simply providing an email address. You must define the rules of engagement—what is considered acceptable testing, how reports should be formatted, and what the reporter can expect in terms of communication and timelines. This creates a "coordinated disclosure" environment where vulnerabilities are fixed before they are publicly announced.

How to meet it

Evidence an auditor asks for

  • A live URL or PDF copy of the public-facing Vulnerability Disclosure Policy.
  • Internal Standard Operating Procedures (SOPs) detailing how reports are handled once received.
  • Records of vulnerability intake, including timestamps of reports received and subsequent remediation actions taken.
  • Correspondence logs showing communication with external researchers to prove the policy is active and functioning.

Common pitfalls

  • Using generic "Contact Us" forms that route security reports to general customer service teams who are not trained to handle them.
  • Threatening legal action against researchers who discover flaws, which contradicts the intent of a disclosure policy and may be viewed as non-compliance.
  • Creating a public policy but failing to establish an internal engineering workflow to actually fix the reported vulnerabilities.
