MessageLabs has unveiled new web filtering services to ensure employees adhere to corporate internet policies.
The new services scan web traffic for viruses, spyware and traffic to and from sites not approved by the business.
The Web Protect service's anti-virus protection uses multiple virus-scanning engines, and scans incoming and outgoing web traffic for spyware, adware and phishing attacks.
The Web Control service includes address filtering to let companies control how employees use the internet.
The new products are MessageLabs' response to blended attacks, which consist of spam messages containing potentially harmful URL links, and the increasing number of malicious websites that can accessed by employees.
Firms can combine both new services for around £4 per user per month.
MessageLabs says its message and web filtering expansion is in response to greater competition in the market.
Among other developments, Verisign recently launched an e-mail filtering service for businesses. Speaking at last weekend’s NetEvents IT Symposium in Italy, Paolo Ardemagni, Verisign vice-president of enterprise security services, said Verisign had so far signed up 50 large companies worldwide to the service – a high proportion of them in the UK.
