The company found that roaming laptop users are much more likely to try to access illegal file sharing sites, porn sites and other questionable content putting employers at risk of legal liability and exposure to malware.

An analysis of eight billion web requests processed by the company in March confirms that roaming workers visit these websites significantly more when they are outside the office.

Specifically, roaming workers visit the following sites more than their colleagues in the office:

- Illegal file sharing sites 8.5 times more often
- Porn sites 2.5 times more often
- Extreme websites (sites with extremely graphic content) 5.2 times more often
- Illegal activities sites (eg. sites with information on building explosives) 3.9 times more often

"It's no surprise that web browsing habits change when employees are outside of the physical confines of their office and away from the watchful eye of supervisors and colleagues," says Dan Nadir, vice president of product strategy at ScanSafe.

"What is surprising is that there is such a huge increase in requests for what most organisations would deem highly offensive sites and in some cases illegal content - including the download of copyrighted material. If your employees are using a corporate-issued laptop to download illegal music files from home, your organisation could be liable."

Interestingly, there is one category of sites that remote employees are less likely to visit when they are out of the office - banking sites. According to the data, roaming employees are 66 per cent less likely to visit an online banking site.

According to ScanSafe many companies are not securing web use for their remote workers. Extending security solutions for roaming laptop users is complex, hard to maintain, expensive, and falls short of offering full 'roaming' protection. In January, ScanSafe launched Anywhere+, the world's first ever software-as-a-service (Saas) web security providing real-time protection from malware and enforcement of acceptable Internet usage policies for all users surfing the Web regardless of their location.
