Product teams should own the content of each row, because they know why an integration exists. A single central owner, usually security or platform engineering, should own the template, the tooling and the review cadence. Shared ownership with no named lead is how inventories go stale.
Why a pure central model fails
A security team that tries to maintain the whole list by itself learns about new integrations after the fact. It sees a vendor domain in a log, then chases someone to explain it. The list is always behind, and the people doing the chasing become a bottleneck.
A pure team model fails the other way. Every team keeps its own spreadsheet in its own format, and nobody can answer a simple question such as "which services call this vendor?" when that vendor reports a problem.
A workable split
| Role | Owns |
|---|---|
| Product team lead | Accuracy of their rows, adding a row before a new integration ships, retiring rows when integrations are removed |
| Engineer who adds the integration | The initial entry: vendor, purpose, data sent, credentials location |
| Security or platform owner | The template, the discovery checks, the quarterly review, the escalation path |
| Privacy or legal contact | Review of rows that send personal data |
| Procurement or finance | Matching paid vendors to rows |
What the central owner actually does
- Publishes one template. Keep it short enough that people fill it in. Hostname, vendor, owner, purpose, data classes sent, environments, and last confirmed date cover most needs.
- Runs discovery. Compare the inventory against dependency scans and outbound traffic, and send each team a short list of mismatches.
- Sets a review rhythm. Quarterly is common. High-risk rows may deserve more often.
- Defines what blocks a release. For example, a new integration that sends customer data must have a row and an approver before launch.
- Reports upward. Coverage, stale rows and unowned rows, in plain numbers.
Putting it in the workflow
The cheapest control is a question in the pull request template or design review: does this change add a new third-party SDK or API? If yes, link the row. That puts the ownership moment where the decision is made.
Name a backup owner for each row. People change teams, and a row whose owner left is the most common reason an old integration is forgotten.
Try it yourself
In the demo below, look at how a gate evaluates a pull request. A rule that asks for an inventory row on new dependencies could sit in the same place.

Quick check
Should security own every row?
No. Security owns the system. The team that uses the integration owns the facts in the row.
What if two teams use the same vendor?
Keep one row per integration per team, linked by vendor, so you can see all users of a vendor at once.
Safeguard offers SBOM and dependency scanning and asset discovery that can feed this kind of inventory. You can run a free scan at gold.safeguard.sh/scan.
