A new piece of hardware from StreamShield Networks could open the door to managed content security services where filtering is conducted in real time.
StreamShield Protector blocks viruses and spam at the internet layer before they get to a company's firewall. It also prevents end-users viewing unsuitable web content, even if their initial requests get through the company's network perimeter.
StreamShield Protector is built around the Streamscan chip, which can scan up to 5,000 e-mails a second for viruses and spam, and filter 250,000 web page requests per second.
Similar products designed for use on customer premises are not as fast and often result in performance degradation for users, according to analysts.
Jose Lopez, an analyst at Frost and Sullivan, said, "I believe the migration of content security into service providers' and operators' networks, so that protection is provided as a managed service to businesses and consumers, is a trend which will fuel the evolution of the market.
"The barrier to this happening so far has been the availability of technology to do this in real time, at very high speeds - something which StreamShield Networks is addressing with its new product."
StreamShield Protector will be available from next month. StreamShield chief executive Simon Gawne said he expected service providers to charge firms between £1 and £4 per user per month for using the system.
Research from Mori found that 60% of internet users look to their ISP to stop viruses, spam and offensive content, and 55% said they would pay extra for the service.
