Super-fast, automated, and rebootless patching of vulnerabilities for Linux kernels
Kernel updates are extremely important for the security and compliance of your Linux systems including CentOS, RHEL, Ubuntu, Debian, and others. Vulnerabilities can expose servers to malicious intent. However, rebooting servers to apply kernel updates can be frustrating for your IT department. Staying up at night to deliver patch updates, worrying about the servers not booting up, coordinating maintenance windows with business units often delay Linux kernel security patching, leaving your infrastructure vulnerable and non-compliant.
KernelCare makes patching your Linux kernels simple. It maintains your kernel security with automated, rebootless updates without any service interruption or degradation. It promptly delivers the latest security patches for different Linux distributions applied automatically to the running kernel in just nanoseconds. KernelCare works in both, live and staging environments, and for servers located behind the firewall, there is an ePortal to help you manage it.
