You may have heard that Intel/AMD processors going back a decade all contain serious design flaws that's prompting changes to Linux, Windows, and macOS kernels.
Keeping customers secure is always our top priority, and Guardian Digital has taken steps to make sure all of our users are protected.
Guardian Digital was first made aware of these issues back in May, and since that time has been working with kernel engineers on the development of fixes to our entire network of secure mail servers, both physical and virtual.
With the public disclosure of the security vulnerability, we can now state that we have completed the planned maintenance of all systems involved and all systems are fully protected.
We’ve worked to optimize the CPU and disk I/O path and are not seeing noticeable performance impact after the fix has been applied. All systems are designed with abundant additional processing power such that performance will not be affected.
