Secure MongoDB Atlas with Automated IP Access List Policies
MongoDB, Tuesday, November 3rd, 2026
MongoDB explains how Atlas Resource Policies enforce approved IP access lists to prevent overly permissive database network access.
In the first of a five-part series, MongoDB describes how MongoDB Atlas IP access lists and Resource Policies support defense in depth.
An IP access list controls which IP addresses, CIDR ranges or AWS security groups can connect to clusters in an Atlas project, with up to 200 entries per project.
Manual management leads to configuration drift, overly permissive entries and poor visibility into who added which addresses.
Atlas Resource Policies turn these practices into enforced guardrails so teams cannot add IP entries outside an approved list, applied at scale across the organization.
