Introduction

Atomic Secured Linux(tm), or "ASL" for short, is a Unified Security Suite addon for Linux(tm) systems designed to protect servers against zero day threats. Unlike other expensive security "solutions" that pretend to achieve security through signature-based detection, known-vulnerability patching and other reactive methods, Atomic Secured Linux(tm) provides real proactive security. The only solution that protects both your applications and operating system, Atomic Secured Linux is essential for public-facing servers and shared-hosting environments.

And Atomic Secured Linux (ASL) is uniquely designed for beginners and experts alike. You just install ASL onto your existing system and it does the work for you, plus you can try it for free!

ASL works by proactively immunizing the system against whole classes of vulnerabilities, and combines security at all layers, from the firewall, to your applications and services, and all the way down to the kernel to provide the most complete multi-spectrum protection solution available for Linux servers today. It helps to ensure that your system is secure and also compliant with commercial and government security standards. ASL is uniquely effective at addressing emerging threats posed by vulnerabilities in todays complex systems and applications, such as cloud and web hosting environments, multiuser systems, CRM's, ERPs, forums, shopping carts, Content Management systems, custom applications and more.
