Preempt Attacks with Proactive Defense in Imunify360

Shield Linux web servers from known and unknown malware!

New feature now available in Imunify360
Proactive Defense™ stops even the malware that scanners are unable to detect!
Software vulnerabilities are constantly being exploited and monetized. In fact, the number of new Linux malware programs increases threefold each year. Malware scanners focus on scanning and identifying infected files already on your system, but how do you protect against new security threats? The solution is Proactive Defense, an unprecedented defense against known and unknown attacks.

Proactive Defense protects websites running PHP, the most common programming language, against zero-day attacks. It identifies attacks on your Linux web servers in real time, then blocks potentially malicious executions automatically and with zero latency. Proactive Defense uses a unique method of identifying security risks - it analyzes what scripts do rather than what is actually in the code or file.

Make vulnerabilities on your servers unexploitable

Even if you keep the software running on your server secure and up-to-date, your customers don’t. They run applications like WordPress, with dozens of plugins. Some of those plugins, even the most popular ones, will make their site (and your server) more susceptible to hackers. The Proactive Defense feature of Imunify360 protects against these and other unknown vulnerabilities and exploits.
Defeat new malware before it hits your server

Unlike malware scanners that consistently scan and rescan files to recognize already infected files based on signatures, Proactive Defense analyses scripts and recognizes dangerous behaviors in them in real time. It stops malware, both new and old, from running on your servers in the first place.
An all-in-one solution for 360-degree protection

Imunify360 now protects against both known and unknown vulnerabilities, giving you complete, automated security to combat viruses, adware, spyware, Trojans, and worms. The combination of Proactive Defense, Malware Scanning, and WAF ensures that all incoming and existing data and traffic gets scanned for malware and blocked once detected. Installed in just minutes, it starts defending servers instantly.

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

Millions of malware strains are focused on attacking web applications. Imunify360 identifies and stops them.

PHP is the most popular scripting language, with more than 80% of server-side scripts running web applications. Because of this wide application usage, PHP is constantly exploited by hackers, making sites vulnerable. Popular CMS applications - including Joomla, WordPress, and Drupal - often introduce security flaws into web applications through the use of plugins and custom scripts, or when not updated to the latest version. Millions of different malware strains are focused on attacking those applications, yet, they all do the same thing. With only a few lines of code, hackers can inject malware, deface your site, or escalate privileges. We analyzed thousands of malware samples to develop heuristics to distinguish malicious behavior from an execution of legitimate scripts. We have tested Proactive Defense for false positives on most common CMS and e-commerce applications, and a large number of popular plugins. Due to the diversity of samples collected from websites all over the world, and thanks to the cloud heuristics of Imunify360, we have developed an exclusive and diverse database of insights that ensure the ultimate protection against attacks.

In the industry where malware cleaning and removing solutions dominate, Imunify360 with Proactive Defense prevents malware from running in the first place.
Imunify360’s Proactive Defense intercepts all activity in real time, analyzes the behavior of PHP scripts, and stops any known or unknown malicious codes from being executed. It is a PHP module that intercepts system calls, file system operation, and more, then analyzes those items to recognize patterns. It uses advanced heuristics to detect potentially dangerous execution sequences and stops those sequences before they harm your servers. Imunify360 allows administrators to tailor the mode according to their preferences. In log mode, it records events for the review. In kill mode, it kills the script execution identified as dangerous. Unlike malware scanners that consistently scan and rescan files while negatively impacting I/O, Proactive Defense has only a minimal performance impact. With zero I/O impact and less than 3.5% overhead, hosting providers and website owners no longer need to choose between speed and security.
All in one nicely packaged application.
The Imunify360 interface allows administrators to manage all security settings from a single dashboard. As an owner of the web server, you can review what is happening on your sites. Server owners are able to inspect file content and view logs showing the script name, IP, and URL used to trigger the event, as well as the environment variables. Website owners can also whitelist particular scripts, if necessary. Web hosting providers that run Imunify360 can enable Proactive Defense for their website owners, giving them full control of the feature and even the ability to disable it. Imunify360 is integrated into your control panel (cPanel, Plesk & DirectAdmin available now, ISPmanager, & stand-alone installation) - click here to take a look at it, free for 30 days.
