There are currently multiple locations to sign up for notifications from MongoDB.
A central location on the Support Portal UI would help Customers to get the information relevant to them.
Current options include:
The MongoDB Alerts page lists critical alerts and advisories for MongoDB Products.

RSS feed of all CVE vulnerabilities, which allows customers to subscribe and receive new CVEs alerts as they are published.
The CVE RSS feed can be accessed here: https://www.mongodb.com/alerts/rss

The Standard security alerts page is here.
Please also see the KB: How can I track security updates from MongoDB?.

You can subscribe to MongoDB Cloud related status updates here.

There is also a MongoDB Release Announcements newsletter for Enterprise products (Server, BI Connector, Ops Manager, and Compass). This is a lower volume list that only includes production (GA) releases. There are typically 2-3 announcements each month.
