Software maker Vontu introduced version 4.0 of its Vontu gateway, which sits on a network and monitors the content of email and instant messages. The San Francisco-based company said the product will stop emails that violate security policies from being sent. “The ability to block the leaks of sensitive or confidential business information is of tremendous benefit and value to those individuals charged with minimizing data security and privacy risks,” said Larry Ponemon, head of the Tuscon, Arizona, think tank the Ponemon Institute.
For years, companies have focused security efforts on keeping hackers out of their networks. A new breed of companies such as Vontu and its rival Vericept have built data interception products that monitor email, instant messages, FTP files and other electronic communications on corporate networks, sniffing for leaks of sensitive information. It does nothing to prevent a partner or a disgruntled employee from downloading information onto a data stick via a USB port or printing the information and walking out the door with it.
Vontu CEO Joseph Ansanelli said that the new release is intended to avert such breaches, but noted that such data interception products are only a small piece of the overall solution for businesses. “With every release of our product, we’re taking steps to increase that protection. I think the market will evolve very much like the firewall market did. First, you had gateway products protecting the perimeter, and now you have personal firewalls sitting on desktops.”
There is one drawback: Because the Vontu product sits within the data path, monitoring and making decisions on traffic in real time, network performance suffers slightly, Ansanelli said.
