The setup of patch management software typically requires some initial configuration. However, once the setup is complete, the entire process becomes seamlessly easy.

1. Identification of missing patches: Patch management tools come equipped with built-in scanners capable of detecting missing patches, whether they are related to security or non-security.

2. Retrieving missing patches: Upon identifying devices with missing patches, the subsequent step involves downloading the corresponding patches. In this phase, a copy of the patch is downloaded and stored locally. Third-party tools utilize WSUS to download these patches, storing them in a central server connected to every device in the network.

3. Testing patches in a controlled environment: Following the download of patches, it is imperative to conduct testing. This ensures that the deployment of patches does not lead to network disruptions. Occasionally, critical vulnerabilities may surface in a new patch, warranting caution before applying the latest updates.

4. Deploying patches across the network: Post-testing, the patch management tool centrally deploys patches to the devices. These tools offer granular control over deployment, featuring pre and post-scripts, reboot control, and more.

5. Confirming patch application: Upon completion of the patching process, the subsequent crucial step is verification. Patches might encounter failures due to unforeseen circumstances, necessitating a repetition of the process. A robust patch management software such as SanerNow significantly diminishes the likelihood of patch failures.
