SanerNow Patch Management User Guide

Applying security patches is the primary method for eliminating vulnerabilities in software. Patch management involves deciding what patches should be applied and when they should be applied and applying the patches. SanerNow provides access to the latest vendor patches that experts test. With its capability to identify vulnerabilities and map appropriate patches to remove vulnerabilities, SanerNow automates the process of security patch management and keeps endpoint systems up to date. SanerNow also provides crucial information on the severity of detected vulnerabilities, which helps decide whether to apply patches.

Patch Management automates the end-to-end patching tasks from scanning to deployment to reduce the attack surface and enhance security posture effectively. It supports patching for all major OSs such as Windows, Mac, Linux, firmware, and many third-party applications. Patch Management detects all the missing patches for the vulnerabilities across the network. Patch management help to simplify and automate all the patching needs. With the help of smart patching technology, SanerNow provides an end-to-end automated patch management system.
