The importance of web filtering for businesses cannot be understated. Businesses can install a range of perimeter defenses, but if controls are not implemented to restrict the activities of employees, malware can easily be downloaded onto work devices. The cost of mitigating malware infections can be considerable. The NotPetya malware attacks last year cost Maersk around $300 million. The Ponemon Institute annual cost of a data breach study suggests the average cost of a data breach is now $3.6 million for large businesses.

There is no single software solution that can provide total protection for businesses. A range of security solutions are required to reduce risk to an acceptable level, and web filters are one such control that should now be used by all businesses.

A new campaign has been detected this week that demonstrates the importance of web filtering for businesses, highlighting one of the methods used to install malicious software on corporate devices. In this case, the aim of the campaign is to install adware, unwanted browser extensions, and PuPs, although this tactic is often used to install much more malicious software.

The individuals behind this campaign are using autogenerated content to create large quantities of websites that incorporate commonly used keywords related to popular celebrities and adult industry actors. The aim of the campaign is to get these webpages indexed by the search engines and appearing in the organic search engine listings.  Individuals who search for these keywords are likely to be presented with these webpages.

Upon opening these webpages, a popup is launched that advises the user that their computer lacks the codecs and software necessary to play the video. To get the videos to play, they need to install a media player. If the end user chooses to install the media player, rather than the media player being installed, a bundle of other programs is downloaded and installed on their device. The campaign also directs users to webpages where they are encouraged to install browser extensions.

If an employee is actively searching for inappropriate website content, it is easy to see how that individual would proceed with a download, and in doing so, install any number of potentially malicious programs.

This is not a hypothetical situation – many employees do just that. A recent survey conducted by Spiceworks delved into the reasons why companies are increasingly using web filters. The primary reason was to prevent the installation of malware. Further, when asked about whether employees had caused problems by accessing inappropriate website content, 38% of respondents said they had experienced a data breach in the past 12 months as a result of employees visiting websites that were not necessary for work.

The survey also revealed the extent that employees are using the Internet for personal reasons. Out of the companies that had not implemented a web filter, it was estimated that 58% of employees were wasting more than 4 hours a week on personal internet use, while 26% of employees were wasting 7 or more hours on non-work-related websites. That adds up to 26 days a year lost by each of those employees.

A web filter can allow a company to improve the productivity of the workforce. Employees will always slack off from time to time, but web filters can help to reduce the number of lost hours. The survey showed that the percentages fell to 43% spending more than 4 hours a week on non-work-related sites and 18% spending more than 7 hours a week slacking off online when a web filter was deployed – a significant reduction in lost hours.  Further, blocking social media websites saw the figure fall to 30% of employees wasting more than 4 hours a week on personal internet use.

Another important benefit of web filtering is to prevent the accessing of illegal website content. Companies can be legally liable for illegal activities by their employees, such as the downloading of copyright protected material through peer-to-peer file sharing networks. The survey revealed two thirds of companies were using their web filter to avoid legal liability and 84% were using a web filter to stop illegal activity online. Data leakage is also a serious concern. 57% of companies use web filters to prevent data leakage and hacking.

If you want to improve your security posture, reduce the potential for productivity losses, and reduce legal liability, a web filter and at least some form of content control is essential.
