Vendor audit requires a vulnerability management policy, where do we start preparing the document?

Enterprise auditors review hundreds of vendor documents; they can spot generic copy-pasted text from the first paragraph. Never put anything in the policy that you cannot actually do. For example, if you write 'Third-party penetration tests are conducted monthly,' they will ask for the invoice and the report, and you can't budget for monthly pen tests on a 45,000 EUR deal. Just document what you actually do.

Don't back yourself into a corner with your timelines. Small teams that write 'Patches deployed within 24 hours' for critical vulnerabilities end up putting their contracts on the line during the very first incident. Set 7 days for critical 30 days for high, and 90 days for medium. Keep emergency patching separate from routine maintenance windows.

Reference the CVSS scoring framework directly in the document. Set clear technical thresholds, such as 'Vulnerabilities with a CVSS v3 score of 9.0 and above are classified as critical.' Also split your vulnerability sources into two buckets: external dependencies (open-source packages) and infrastructure/server OS patches. You track and handle the two differently.

Downloading a template and sending it off might buy you peace of mind temporarily, but if the client is an enterprise French firm, they will ask for technical proof right after approving the paperwork. If you don't have an actual scanning tool, version history, and resolution tickets to show, generating pure paper could turn into legal liability down the line.

we used a template for a similar audit but appended export formats from the free scanners we use. auditor asked straight up for the latest scan report showed it and had no issues. doc by itself isn't enough keep an export file handy.

Large enterprise buyers in France audit suppliers under binding contracts per supply-chain security regulations. Once signed, the policy document legally acts as an appendix to the commercial agreement. Because of this, the patching timelines you commit to must strictly match your company's actual technical bandwidth.

dont overthink it, nobody expects a 50-page defense-contractor standard from a 9-person software shop. btw a practical 3-to-4-page document that lays out a clear process names the person responsible, and gies a dedicated email address is more than enough to satisfy most auditors.

once this document is drafted, are we required to get it certified by an independent third-party auditor or notary or are a company stamp and a founder's signature considered sufficient?

The most overlooked point about vulnerability management is this: Most incidents start with a leaked password, not a vulnerability.

Proven by experience.

Three different views emerged, they all complement each other. I mean forgotten test environments are more often the entry point than live systems.

Thats all, sorry if I went on too long.

Quick summary for newcomers: If the notification path is long, notifications don't arrive; missing notifications mean delayed incident detection.

Just leaving this note it might be useful.

Yes, that's exactly how it is with vulnerability management. Security isn't absolute; it's about making attacks not worth the effort.

The discussion got scattered, let me summarize. When making decisions, write down the worst-case scenario too, not just the best.

Quick summary for newcomers: When we decide without measuring, we always end up in the same place.

That's all sorry if I went on too long.

I have no experience with vulnerability management, so I'm asking. Taking measures without an inventory leaves doors you haven't seen open.

Quick summary for newcomers: When you try to change everything at once, nothing settles.

Everyone rushing into vulnerability management gets stuck at the same point. If you have questions, write them; I'll answer as best I can.

I'm in the same situation, that's why I'm asking. Don't hesitate to ask; those who don't ask always pay more.

Trying to do this alone is the most expensive way. Just leaving this note, it might be useful.

I'm writing this so you don't make the same mistake. Mistakes made on the vulnerability management side are usually reversible but expensive.
