Sign Up Now!   Atomic Secured Linux(tm) is an easy to use out-of-the-box Unified Security Suite addon for Linux(tm) systems designed to protect your servers against both known and unknown zero day threats. Unlike other security solutions, ASL is designed for beginners and experts alike.  You just install ASL and it does the work for you. ASL works by combining security at all layers, from the Kernel all the way up to the application layer to provide the most complete protection available for Linux servers and helps to ensure that your system is complaint with commercial and government security standards. ASL includes the most harderned kernel on the market, automated system hardening techniques, userspace and host Intrusion Prevention Systems (IPS), malware/rootkit detection and elimination, blacklisting technologies, an autolearning Role Based Access Control System and web application firewalling to protect multiuser and web application hosting environments like no other solution. ASL is uniquely effective at addressing emerging threats posed by vulnerabilities in todays complex systems and applications, such as web hosting environments, multiuser systems, CRM's, ERPs, forums, shopping carts, Content Management systems and custom applications.

The design of ASL approaches securing the server and its applications, by combining different layers of security technologies and application layer firewalls to filter out malicious content before it reaches your system and its applications. Our hardened kernel further enhances the overall security model by enforcing anti-rootkit, file, network and process level security policies on the system.

The ASL approach also includes our "Just In Time Patching" system, which allows you to address security threats posed by applications where either it is not possible to fix the application due to lack of source code, availability of resources, or the number of applications that make repairing all vulnerabilities economically unfeasible. You can known that your systems are protected, even when you can't patch them.

Dependability ASL is in its third year and is a mature, reliable product brought to you by founders of Plesk, so you know it will work with your server the way you want to use it! When you use ASL, you are not only using the software but the collected experience of our team of security and systems experts. And we aren't new comers to Linux, our Founders have been building Linux based systems before the 1.0 kernel came way out back in the mid 90s. We know and love Linux, and when you use ASL you get that same attention to detail we not give only our customers, but our own systems!  We use every feature in ASL on every Linux system we use.  You can depend on ASL, because we depend on it too.

Ease of Use

"Security for Everyone" is our mantra.  We designed ASL so that anyone can use it and so that it works out of the box to protect your system.  ASL does not require you to be a security expert.  We built ASL so that anyone can protect their systems without any security background at all.  With ASL you can have the same level of protection that comes with a team of security experts, all wrapped up into one product.

Zero Day Protection

Unlike other security products, AtomicSecured Linux does not depend on signatures that require constant updating as it includes technology to detect and stop entire classes of attacks such as buffer overflows, SQL injection, cross site scripting and more!
