Veeam Software Security Commitment
Veeam® is committed to ensuring its products protect customers from
potential risks. As part of that commitment, we operate a
Vulnerability Disclosure Program (VDP) for all Veeam products and
perform extensive internal code audits. When a vulnerability is
identified, our team promptly develops a patch to address and
mitigate the risk. In line with our dedication to transparency, we
publicly disclose the vulnerability and provide detailed mitigation
information. This approach ensures that all potentially affected
customers can quickly implement the necessary measures to safeguard
their systems. It’s important to note that once a vulnerability and
its associated patch are disclosed, attackers will likely attempt
to reverse-engineer the patch to exploit unpatched deployments of
Veeam software. This reality underscores the critical importance
of ensuring that all customers use the latest versions of our
software and install all updates and patches without delay.
