CloudLinux’s Imunify360 Proactive Defense™ Preemptively Protects Linux Web Servers Against Attacks

Imunify360 adds the Proactive Defense™ feature to protect against known and unknown vulnerabilities, making it the most effective and complete security solution for web servers.

Palo Alto, CA, July 17, 2018  - CloudLinux, the maker of the #1 OS for hosting providers, has announced the release of Proactive Defense in the Imunify360 security solution for Linux web servers. Proactive Defense continuously analyses running scripts and recognizes dangerous behaviors in them in real time. It prevents malware, both new and old, from running on servers.

Imunify360 is an all-inclusive, comprehensive security solution that helps protect Linux web servers against most types of exploits, and with its Proactive Defense feature, it will stop most, if not all, attacks. It stops even the malware that malware scanners are unable to detect. The Proactive Defense feature delivers a significant improvement in anti-malware effectiveness and is the first solution of its kind for Linux web servers.

"After extensively testing proactive defense, we're confident that it will stop almost all malware in real-time,” said Patrick William of RACK911 Labs. “Combined with the other features of Imunify360, there is nothing else on the market that offers such a high level of security."

Imunify360 blocks attacks through a combination of technologies: signature matching, real-time behavior analysis for blocking malware, and herd immunity powered by insights collected from servers all over the world.

“Preemptive security is the best kind, and Proactive Defense has now made our multi-layer security into one rock-solid solution,” - said Igor Seletskiy, CloudLinux CEO. “For the past several weeks, Imunify360 with Proactive Defense beta has been broadly tested while running on a few hundreds of servers and thousands of websites. We are happy to share that there has been not a single false positive report for the Proactive Defense feature, and we are working hard to ensure that those will be minimal to none going forward.”

Imunify360 all-in-one, sophisticated security solution protects servers from attacks and includes many types of protections, such as:

  • Malware Scanner to detect all vulnerable files

  • Unknown -- zero-day -- attacks prevention with script blocking of Proactive Defense (new!)

  • Protection against remote exploits with IDS/IPS and WAF

  • Protection against brute force attacks, DoS attacks, and port scans with the Advanced Firewall

  • Automated kernel security updates to combat critical vulnerabilities such as Meltdown (without reboots) with KernelCare
