Nexor Guardian by Nexor is a highly secure, high-throughput content checking solution designed to enable the sharing of information between networks with different trust levels. It ensures that data flows in the intended direction, aligning with the architecture of the system. Nexor Guardian combines deep content inspection with antivirus checking to ensure only validated data enters the network. It reduces the risk of unauthorized information release from high networks through security labeling and deep content inspection, including dirty word and hidden content checking. Nexor Guardian protects organizations by validating that data conforms to the security policy of the protected domain. It uses evaluated security functionality to ensure automated electronic exchanges occur only through a trusted path. All information is scanned by a policy enforcement module that validates compliance with the defined security policy. Non-conformant information is rejected and quarantined, preventing outbound data loss or inbound malicious content. Nexor Guardian is available in multiple versions, optimized for specific business challenges, and can be deployed either as a physical appliance or virtually into a customer environment.
