+# Security Policy
+
+## Supported versions
+
+Only the latest release of linearmodels is supported. This is currently the
+7.1.x series. Security fixes are not backported to earlier releases, so please
+upgrade before reporting a problem that you found in an older release.
+
+## Reporting a vulnerability
+
+Please report suspected security vulnerabilities **privately**. Do not report
+them in a public issue, pull request or discussion, since that tells everyone
+about the problem before a fix is available.
+
+The preferred way to report a vulnerability is GitHub private vulnerability
+reporting:
+
+<https://github.com/bashtage/linearmodels/security/advisories/new>
+
+If you cannot use GitHub, email the maintainer, Kevin Sheppard, at
+<kevin.k.sheppard@gmail.com>, which is the address listed in `pyproject.toml`.
+Use a subject line that makes clear that this is a security report, for example
+"linearmodels security vulnerability".
+
+## What to include
+
+A report is easiest to act on if it contains:
+
+- A description of the vulnerability and its impact: what an attacker can do,
+  and what they need in order to do it.
+- The affected function, class or module, and the version of linearmodels where
+  you found the problem.
+- Steps to reproduce the problem, ideally as a short, self-contained script.
+- The versions of Python, NumPy, SciPy, pandas and statsmodels, and your
+  operating system.
+- A suggested fix or mitigation, if you have one.
+- Whether the problem has been disclosed elsewhere, any disclosure deadline that
+  you plan to follow, and whether and how you would like to be credited.
+
+## What to expect
+
+linearmodels is a volunteer project, so responses are best effort. There is no
+guaranteed response time or fix date. For a confirmed vulnerability, the
+maintainer will work with you on a fix and on the timing of its disclosure.
