Keep reading for a few best practices that are ideal in a remote patch management scenario:

  • Prioritize security updates over non-security and optional updates.

  • Directly download patches to endpoints, rather than downloading them in your server and distributing them to remote locations.

  • Schedule automation tasks specifically for deploying critical patches for timely updates.

  • Plan to set broad deployment windows so that critical updates are not missed due to unavoidable hindrances.

  • Allow end users to be able to skip deployments to avoid a disturbance in productivity.

  • Ensure the machines under your scope do not run any end-of-life OS or applications.

  • Always test the patch updates before deploying them to the endpoints.
  • Ensure you use a secure gateway server to establish a safe connection between your remote endpoints.
