Web Filtering

What is Web Filtering?

A Web filter is a piece of software designed to restrict the websites a user can visit on his or her computer. Web filters are used to prevent malware entering an organization, filters can be set to block access to sites that commonly host malware, such as those related to pornography or gambling.

Web Filtering Software

Web Filtering software is an important protection against a range of web threats. Web filtering software prevents end users from visiting websites that contain these malicious threats.

Web filtering software is one of the most effective ways to neutralize phishing attacks. Phishing is a form of fraud where an attacker impersonates a trustworthy entity or person in email or other forms of communication. Cybercriminal often use phishing emails to distribute malicious links and infected attachments. The purpose is to extract login credentials or account information from victims. These attacks  target hundreds of millions of organisations every day.

Web filtering software prevents end users from visiting websites known to contain malware or exploit kits and blocks botnet activity and communications with hackers’ C&C servers. The software can be configured to also block malicious third party adverts on websites (malvertising).

 

How does Web Filtering Work

Web filtering works by using either a hardware or software-based solutions to establish filtering rules around what categories of website can be visited by the user. Content is grouped into categories—for example finance, news, sports, gambling, adult,  the websites in categories deemed dangerous or unnecessary are blocked on the network.

The WebTitan URL classification system is based on  users actively visiting URLs, as opposed to  classifying bot traffic. The classification uses a crowd-sourced approach for obtaining a constant stream of URLs to analyze. The continuous stream of URLs actively being visited by 500 million  end users is the primary in-house source for threat corpuses and comes from a global network of customers. This approach allows us to continuously enhance, optimize and tune malicious detection capabilities in an ever-changing threat landscape.

A network that isn’t well-protected can be infected with malicious spyware and hackers can easily to obtain sensitive information that within seconds can be passed on to individuals that can use it for financial gain. Security incidents like this can be hugely detrimental to businesses and highlight that web filtering and cyber security  is absolutely essential.

Ensuring children are not exposed to inappropriate content is an obvious use case for web filtering. DNS filtering, a specific type of web filtering uses the DNS layer to filter based on IP addresses. DNS web filtering is becoming increasingly popular as a means of managing internet usage. With DNS filtering a potentially dangerous site can be blocked before they have a chance to drop malicious payloads.

 

Enterprise Web Filtering Service

An enterprise web filtering service works to protect an organizations network from web-borne threats by blocking access to dangerous websites and file types likely to be infected with malicious software or “malware”. Enterprise web filtering solutions can also enhance workplace productivity, prevent potential HR concerns, address bandwidth issues and improve the service an organization delivers to its customers.

Enhance Productivity via Web Filtering

Some personal use of the Internet at work is considered to have a positive impact on workplace productivity, however excessive non work-related social media use has been calculated to cost businesses billions of dollars each year.

Enterprise web filtering includes mechanisms that allow bespoke filtering configurations to limit access to social media accounts, online shopping portals, gambling sites and other non-work related activities. Administrators use web filtering solutions to blacklist content that is considered inappropriate for their users such as porn, violence, and profanity. Web filters prevent underaged users from accessing adult content while also preventing potential HR concerns and allegations that an employer is complicit in creating a hostile working environment.

Enterprise web filtering services automatically generate reports that administrators can use to monitor compliance with acceptable use policies and ensure that employees are not attempting to bypass filtering rules. In order to prevent employees bypassing filtering settings, it is recommended to implement an enterprise level web filtering solution that can block anonymizer services.

 

How Web Filtering Eliminates Bandwidth Issues

A further benefit of web filtering services is that they can be used to eliminate bandwidth issues. Few organizations have unlimited bandwidth, bandwidth abuse causes severe latency and network crashes. Organizations experiencing bandwidth issues can pay for more bandwidth or reduce their bandwidth usage.

One way of reducing bandwidth use is to restrict access to websites such as Netflix and YouTube using an enterprise web filtering service. By restricting access to bandwidth-heavy applications organizations can ensure adequate bandwidth is available to employees.
