The Diamond IP Sapphire v5 appliance from BT provides basic level performance with superior reliability and security with the convenience of pre-packaged DHCP/DNS/IPAM (DDI) appliances.

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.
