+# Security Policy
+
+## Latest Versions
+
+We advise users to run the most recent mainline or stable release of nginx.
+
+## Reporting a Vulnerability
+
+Please report any vulnerabilities via one of the following methods
+(in order of preference):
+
+1. [Report a vulnerability](https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing-information-about-vulnerabilities/privately-reporting-a-security-vulnerability)
+within this repository. We are using the Github workflow that allows us to
+manage vulnerabilities in a private manner and to interact with reporters
+securely.
+
+2. [Report directly to F5](https://www.f5.com/services/support/report-a-vulnerability).
+
+3. Report via email to security-alert at nginx.org.
+This method will be deprecated in the future.
