+### Security Release Stewards
+
+When possible the commitment to take slots in the
+security release steward rotation is made by companies in order
+to ensure individuals who act as security stewards have the
+support and recognition from their employer to be able to
+prioritize security releases. Security release stewards manage security
+releases on a rotation basis as outlined in the
+[security release process](./doc/contributing/security-release-process.md).
+
+The current set of security release stewards is as follows:
+
+* Data Dog
+  * [bengl](https://github.com/bengl) -
+    **Bryan English** <<bryan@bryanenglish.com>> (he/him)
+  * [vdeturckheim](https://github.com/vdeturckheim) -
+    **Vladimir de Turckheim** <<vlad2t@hotmail.com>> (he/him)
+* NearForm
+  * [mcollina](https://github.com/mcollina) -
+    **Matteo Collina** <<matteo.collina@gmail.com>> (he/him)
+* Red Hat and IBM
+  * [mhdawson](https://github.com/mhdawson) -
+    **Michael Dawson** <<midawson@redhat.com>> (he/him)

+## Security release stewards
+
+For each security release a Security steward will take ownership for
+co-ordinating the steps outlined in this process. Security stewards
+are nominated through an issue in the TSC repository and approved
+through the regular TSC concensus process. Once approved they
+are given access to all of the resources needed to carry out the
+steps listed in the process as outined in
+[security steward on/off boarding](security-steward-on-off-boarding.md).
+
+The current security stewards are documented in the main Node.js
+[README.md](https://github.com/nodejs/node#security-stewards).
+
+The current rotation is as follows:
+
+| Company    | Person   | Release Date |
+| ---------- | -------- | ------------ |
+| NearForm   | Matteo   | Oct 21       |
+| Data Dog   | Bryan    | Jan 22       |
+| RH and IBM | Joe      |              |
