Netsweeper Counter-Terrorism Solution

The Counter-Terrorism and Security Act 2015 was created with the intent of putting responsibility on schools to participate in working to prevent people from being drawn into terrorism. With the increased risk of online terrorists’ radicalization of young people, which commonly occurs through social media, schools without advanced web filtering are at risk. The Prevent Duty Guidance states that “specified authorities will be expected to ensure children are safe from terrorist and extremist material when accessing the Internet in school, by establishing appropriate levels of filtering.” Netsweeper has developed a comprehensive strategy to prevent radicalization and terrorist content from reaching students and is the de facto platform that exceeds the requirements of the Prevent Duty Guidance.


OFSTED, the UK education regulator, has been given the responsibility of monitoring how well the Prevent Duty is being implemented in schools. They are responsible for overseeing how well the school is performing in preventing extremists from seeking to radicalize learners in addition to supporting those learners perceived to be at risk of extremist influences. Netsweeper reports and sends alerts to all stakeholders, fully complies with the reporting practices of schools, and is OFTSED compliant.

Netsweeper is a direct partner of the Counter Terrorism Internet Referral Unit (CTIRU) run by the Metropolitan Police. Under Section 3 of the Terrorism Act, CTIRU removes unlawful terrorist content from the internet or content that incites or glorifies terrorist acts. In addition, CTIRU compiles a list of URLs for material hosted outside of the United Kingdom, which are blocked on networks of the public estate. Netsweeper, being a long-standing partner, with a direct communication channel to CTIRU, has integrated the list of URLs, giving our global community unmatched protection against terrorist and extremist content.

Impede Terrorism & Radicalization




In their efforts at both radicalization and recruitment, terrorists, militias, and other illicit organizations have used social media in a calculated strategy. The Netsweeper platform provides the industry’s most effective controls for managing URLs and web applications, including the ability to control the use of leading social media applications such as Facebook, Instagram, Twitter, Flickr, YouTube, LinkedIn and more. IT personnel can apply policies based on a wide range of criteria, including users, groups, applications, postings, and media transfer controls:

• Allow access to social media sites such as Facebook, but block specific activities within the site, such as messaging or posting.
• Enforce SafeSearch and keyword search controls for all major engines, including media search engines.
• Control whether users can send or receive messages and attachments for all major webmail services.

Furthermore, Netsweeper categorizes URL content in over 90 categories, including “Hate Speech”, “Extreme”, “Criminal Skills”, or “Weapons” using a high-performance local caching to perform maximum performance for URL lookups, while our CNS (distributed cloud architecture) provides coverage for the latest websites. Therefore, if new radicalization content spreads, it takes Netsweeper merely seconds to identify, update, and block malicious content in over 40 languages.
