Highly scalable DNS virtual appliance for use with BT IPControl IPAM
The Diamond IP Sapphire v20 appliance from BT 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 BT IPControl implementation 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 DNS response rate limiting, to name a few.
