Kicksecure is a brand that specializes in TCP ISN (Initial Sequence Numbers) CPU Information Leak Protection. They offer a solution that randomizes TCP ISNs to prevent leaks of sensitive information about a system's CPU activity. This protection is crucial, especially for long-running cryptographic operations, as it prevents side-channel attacks that can compromise the security of the system.

The brand addresses the Linux kernel's side-channel information leak bug, where clock skew is leaked through TCP ISNs. This leak can be remotely detected or induced by an attacker, making it a significant security concern. Kicksecure's kernel module, called tirdad, hot-patches the Linux kernel to generate random TCP ISNs for IPv4 TCP connections, effectively mitigating this vulnerability.

To install tirdad, users can easily follow the steps provided on their website. Kicksecure also encourages donations to ensure the continuous development and maintenance of their solution. With their expertise in security and their commitment to protecting systems from information leaks, Kicksecure is a valuable brand for individuals and organizations seeking robust cybersecurity solutions
