Nexland, a developer of Internet security appliances, signed a letter of intent to be acquired by Symantec for $21.7 million in cash, company executives said.
The deal is subject to numerous conditions before it can be finalized.
Symantec, Cupertino, Calif., currently licenses Nexland's technology for use in its firewall/VPN appliances, according to Nexland. A unique feature in Nexland's technology is its ability to allow encrypted VPN packets to "pass through" the Network Address Translation performed by its appliances, executives said.
Last year, Symantec acquired managed security provider Riptech and intrusion-detection vendor Recourse Technologies.
