The Sapphire v5 appliance from Cygna Labs provides basic level performance with superior reliability and security with the convenience of pre-packaged DHCP/DNS/IPAM (DDI) appliances. The Sapphire v5 can be configured and managed using your Cygna Labs Diamond IP IPControl implementation (also available on AWS as Ev10 or Ev20) to extend your DNS/IPAM capabilities to AWS. Sapphire appliances are built from the ground up for security and robustness. Our appliances offer numerous security features including a hardened operating system (OS), minimal open ports, uninterruptible boot process, jailed file system, and in/outbound rate limiting to mitigate denial of service (DOS) attacks, DNSSEC validation, DNS firewall, and DNS tunneling detection/shutdown.
