Guardian introduces EnGarde Secure Linux

Open source security company Guardian Digital, Inc., Monday introduced EnGarde Secure Linux. Leveraging the best open source applications available, combined with the security expertise from Guardian Digital, EnGarde delivers features designed to ease the process of building a complete Internet presence and the level of security necessary to prevent system compromise.

“The proactive security improvements inherent into its design are one of the primary factors in the success of EnGarde,” said Pete O’Hara, vice president of engineering at Guardian Digital. “Coupled with the most sophisticated open source Web-based management system, EnGarde consistently protects users from even debilitating kernel security vulnerabilities where other Linux vendors fail.”

EnGarde features secure Web-based management of all functions, including Internet edge services (Web, DNS, email), integrated intrusion detection, cryptography, improved authentication and access control, as well as protection from many forms of intrusion such as buffer overruns and denial of service attacks. Enhanced availability and access control mechanisms delivers a potent combination suitable for the largest enterprise.

“Security management is an essential component of any successful online operation. Mitigating security risks through the use of a dynamic, rapidly-evolving development process bolstered by collaboration of the open source community provides the most efficient form of protection,” said Paul Brisson, orthopedic spinal surgeon, New York Spinal Care. “EnGarde Secure Linux and its secure-by-design approach combined with the security benefits engineered by Guardian Digital offer the best in proactive protection.”
