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.
