Thank you for your message.
In response to the Kaseya supply chain attack, and since other similar incidents such as the SolarWinds case, we at Paessler continuously subject our already high security standards to further thorough audits. We constantly examine all systems, processes and protocols to rule out any misuse and discover further improvements.
At the time of the SolarWinds case, we had created a task force for such incidents. This task force continues to coordinate possible resulting improvements on all levels and has already identified and established several processes to harden the software build and delivery pipeline. It also extended our capabilities of vulnerability scanning of external dependencies built into our products.
For our customers that have very high security risk awareness, please note that PRTG has a very fine-grained possibility to either configure the update process from a completely offline installation over only receiving a notification about an update to download and automatically install the update.
For more information about the auto-update feature, see https://www.paessler.com/manuals/prtg/auto_update.
If you have questions, let us know.
