Covergence, a security firm focused on protecting VoIP services, said Friday it raised $15 million in funding in a move that shows venture capitalists are on the prowl for startups that help tackle security threats on VoIP networks. The company raised its third round of funding from new investor Globespan Capital partners, and existing investors Highland Capital Partners and North Bridge Venture Partners. Formed in late 2003, the Maynard, Massachusetts-based company specializes in scaling, securing, and controlling VoIP and other real-time services like instant messaging based on a technology standard called the Session Initiation Protocol (SIP). The latest investment brings the total funding in the company to $31 million. Covergence hopes to use the additional resources to develop new sales and marketing opportunities, expand its sales channel strategy, and extend its geographic footprint into international markets.

Voice Encryption May Draw U.S. Scrutiny
By JOHN MARKOFF
SAN FRANCISCO, May 21 - Philip R. Zimmermann wants to protect online privacy. Who could object to that?
He has found out once already. Trained as a computer scientist, he developed
a program in 1991 called Pretty Good Privacy, or PGP, for scrambling and
unscrambling e-mail messages. It won a following among privacy rights
advocates and human rights groups working overseas - and a three-year
federal criminal investigation into whether he had violated export
restrictions on cryptographic software. The case was dropped in 1996, and
Mr. Zimmermann, who lives in Menlo Park, Calif., started PGP Inc. to sell
his software commercially.
Now he is again inviting government scrutiny. On Sunday, he released a free
Windows software program, Zfone, that encrypts a computer-to-computer voice
conversation so both parties can be confident that no one is listening in.
It became available earlier this year to Macintosh and Linux users of the
system known as voice-over-Internet protocol, or VoIP.

Skype could be a ticking time-bomb with it's security vulnerabilities, and most of the millions of Skypers aren't even aware of it. Even as a telecom security specialists working for a company that produces voice security products, I use Skype even thought it regularly breaches our network firewalls. The problem is that Skype is just too easy to use, the voice quality is superb, and I can't argue with the cost. So even though Skype has some potentially serious security issues, it's hard to argue about the amount of buzz that Skype has generated recently. Full article here. |
