The Cygna Labs Diamond IP Sapphire v20 appliance provides superior performance, reliability and security with the convenience of pre-packaged DHCP/DNS/IPAM (DDI) appliances. The Sapphire v20 can be configured and managed using your Cygna Labs DIamond IP IPControl implementation (also available on Azure as the Sapphire Ev10 or Ev20) to extend your DNS/IPAM capabilities to Azure. Sapphire appliances are built from the ground up for security and robustness. Our appliances offer numerous security features including a hardened operating system (OS), network interface access control lists (ACLs), minimal open ports, uninterruptible boot process, jailed file system, and rate limiting to mitigate denial of service (DOS) attacks, DNSSEC validation, DNS firewall, DNS tunneling detection and shutdown, and DNS response rate limiting, among others.
