Startup Infoblox Inc. is raking in some cash as it attempts to make a case for a range of specialized devices for security and email directory management.

This week the Sunnyvale, Calif.-based vendor picked up $30 million in a Series E round, bringing its total funding to $65 million. The round was led by existing investors Sequoia Capital and Lehman Brothers.

Infoblox is building hardware platforms that will be dedicated to some key network protocols for email, remote access, and e-commerce applications. Specifically, its addressing Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), Remote Acces Dial-In User Service (RADIUS), and Lightweight Directory Access Protocol (LDAP).

Currently, these protocols are supported as software running on standard servers. Infoblox, however, is pushing a range of dedicated 1-rack-unit-high devices for running applications that rely on these specific protolos. The name of these devices is DNSone (which also supports DHCP), RADIUSone, and LDAPone [Ed. note: no CORNPone?].

Using a dedicated box offers users both greater security and reliability, according to Richard Kagan, Infoblox’s vice president of marketing. “They have an operating system, but it is embedded like an operating system in a firewall,” he says. “A hacker can’t touch it.”
