  The ServSwitch™ Secure KVM Switch with USB, EAL4+ Certified, DVI offers not only superior hardware-based data-isolation features, but it has also been certified for Common Criteria Evaluation Assurance to Level 4+ (EAL4+), augmented by ALC_FLR.2 and ATE_DPT.2.
  
  The Common Criteria is an international standardized process for information technology security evaluation, validation, and certification. The Common Criteria scheme is supported by the National Security Agency through the National Information Assurance Program (NIAP). EAL4+ itself defines a common set of tests to evaluate the security of an IT product relating to its supply chain, from design and engineering to manufacturing and distribution.
  
  The ServSwitch Secure KVM Switch with USB, EAL4+ Certified, DVI provides control and separation of four PC CPUs/servers connected to secure and non-secure networks through just one keyboard, monitor, and mouse. Users can safely switch among the connected computers operating at different classification levels without worry.
