Custom alerts and data visualization let you quickly identify and prevent system updating issues.
Paessler PRTG’s professional update and patch monitoring improves your network security and gives you peace of mind by ensuring your active operating systems and applications are always up-to-date.
Software and operating systems constantly evolve as weak spots are eliminated and security loopholes are closed. You must quickly add security updates and patches in order to remove dangerous entryways into your systems.
With PRTG in the background, you no longer need to manually check for the latest versions, and you can rest assured that everything is in order with your Windows and Linux systems, and other hosts.
PRTG helps you keep track of your entire network to avoid missing updates. IT infrastructures tend to expand over the years with new servers, routers, workstations, and other network devices and endpoints from different manufacturers.
Because they’re added to the network at different times, they often run on different versions of an OS or on different systems. Plus, the same patch or update is not always required for every computer. Avoid these update issues with PRTG.
PRTG helps you avoid errors during installations. Like backups, many updates are performed at night to prevent them from disrupting a company’s daily business.
However, if errors occur at night, they’re not always detected the next morning. The PRTG automatic update and patch checker keeps system administrators in the know so you can avoid costly errors.
PRTG helps you close security loopholes and avoid security risks due to outdated software. Without an update and patch checker, security loopholes can quickly crop up in the network – and firewalls and antivirus software often provide for little or no defense against network attacks.
PRTG update and patch monitoring helps system administrators keep their systems secure.

Patches are offered for operating systems and software. They are usually made available when an error is detected which must be fixed at once. Such errors often include security loopholes. Windows, for example, can offer several patches in one package. Each patch detected by the PRTG patch checker has a different version number.
Updates are also used to optimize programs. But unlike patches, they are scheduled in advance and do not take place at once. Updates (or “upgrades”) are offered when new features become available for a system or piece of software. They therefore upgrade and enhance programs. The program is updated and receives a new version number.
Checking for updates and patches is crucial for several reasons, primarily related to the security, performance, and functionality of your software, operating systems, and applications. Here are some key reasons why you should regularly update and patch your systems:
A sensor scans your operating systems for their current version, then inquires online as to the most current version available. If the two do not match, you will be notified or an update will be arranged. An example: PRTG includes the preconfigured Windows Updates Status (PowerShell) sensor so you can be sure your Windows OS is always up-to-date.
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
Paessler PRTG is used by companies of all sizes. Sysadmins love PRTG because it makes their job a whole lot easier.
