Cloud Content Classification and Filtering

The Netsweeper Web Security Platform is driven by core proprietary technology that reviews and categorises new websites in real-time in over 60 categories. This Artificial Intelligence based system or CNS (Category Naming Service) uses the search activities and multi-tenant database patterns of more than 500 million devices filtered worldwide to constantly identify new entities and threats on the Internet. To date, Netsweeper has categorised billions of URLs in 30+ languages.

Granular Web Application Controls

The Netsweeper Web Security Platform provides the industry’s most effective controls for managing Web applications. This includes the ability to control the use of leading social media applications such as Facebook, Instagram, Twitter, Flickr, YouTube, LinkedIn, and much more. IT can apply policies based on a wide range of criteria, including user, group, applications, postings, and media transfer controls:

  •  Allow access to social media sites such as Facebook, but block specific activities within the site, such as gaming or posting.
  • Enforce safe search 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.

Visibility Into Encrypted Traffic with NSProxy

Internet traffic is obscured by SSL, including some of the applications and sites that introduce the most risk for your organisation. Netsweeper’s approach provides the appropriate balance between security and performance by blocking at the hostname or by using NSProxy.

NSProxy service is an advanced high speed proxy capable of delivering 6Gbps of SSL decryption throughput or support for 20,000 users. NSProxy solves a key filtering issue as more websites become SSL-enabled. The Netsweeper NSProxy can optionally break encryption to examine the HTTP requests secured with SSL/TLS.  The NSProxy service can also filter HTTPS using the Service-Name-Information contained in the SSL/TLS handshake and filter by hostname without breaking encryption.

NSProxy provides selective inspection and decryption at the edge gateway; i.e., allows trusted SSL traffic through and decrypts per your policies for optimal security and throughput.

Dynamic Malware Protection and Security

Netsweeper’s Web Security Platform detects zero-minute and known malware threats. By correlating a combination of current traffic and request trends, multiple detection technologies, automated machine-learning heuristics, and the industry’s largest data set of web content, Netsweeper provides the most effective solution against new and known malicious web content.

Netsweeper’s signature-based scanning detects known web malware residing on both reputable and uncategorised web pages. As is expected in a signature based solution, Netsweeper’s solution utilises multiple anti-malware scan engines which cover all known spyware and viruses, with regular updates hourly and immediate updates for outbreaks. Every new URL requested is automatically scanned utilising this engine and the current URLs in the database are regularly scanned to ensure their current legitimacy.

Flexible Deployment Options

The Netsweeper Web Security Platform was designed as a distributed multi-tenant platform to ensure flexibility and instant interoperability with existing network infrastructures. A simple configuration change to a firewall, router, or proxy solution allows administrators to instantly protect and enforce Internet use policies for all users connected behind the device. Furthermore, optional lightweight mobile and desktop clients are available for Windows, MAC, OSX, Google Chrome, Chrome browser, iOS, and Android ensuring that roaming or off network users are protected regardless of their location.

Prevent Duty of Care Strategy and OFSTED

On the 12th of March 2015, the UK Government issued the Prevent Duty Guidance that places a duty of care on schools stating it is now mandatory for schools to have a “duty regard to the need to prevent people from being drawn into terrorism”.

OFSTED, the UK education regulator has been given responsibility of monitoring how well the duty is being implemented in schools. Specifically, how well the school is performing in preventing extremists from seeking to radicalise learners as well as how well they support those learners perceived to be at risk of extremist influences. This this is now a key requirement for OFSTED to inspect moving forward.

To meet and exceed the requirements of the Prevent Duty Guidance Netsweeper has developed a comprehensive strategy to prevent radicalisation and terrorist content from reaching students and staff. Read more about Prevent Duty strategy.

  3. Transparent filtering: Netsweeper Transparent Filtering solution on emPSN is the next generation of web Filtering technology enabled to provide next generation security and network monitoring. The solution will transparently filter all traffic configured to transparently route through the Netsweeper emPSN Cloud solution. Empowering your Internet Experience, this new emPSN solution utilises next generation firewalling as well as Netsweeper’s filtering technology, enabling your users to have a clean, safe, Internet experience. The solution has been implemented with high availability utilising the latest in load balancing and high availability technology to provide a complete redundant and reliant system. Netsweeper aims to deliver market leading technology to the education sector and has done for over 18 years in this sector. With transparent filtering, proxy settings are no longer a requirement with deployment made simply by altering settings at the router level rather than device level. Netsweeper has engineered the solution so that no hardware or software is needed to be installed on the schools site and instead schools can have access to their own administration platform from the cloud. Per user policies and reports can be accessed from the schools platform to deliver highly intuitive and granular control over staff and student access with education based categories.
  4. Client Filter: The Netsweeper client filter is a thin client that can be installed on Windows devices, Chromebooks, Android and iOS devices. It is used for filtering these types of devices when they are taken away from the network, for example school-owned laptops still require filtering when they are external to the school. Netsweeper’s client filter software enables 24/7 filtering regardless of which network the device is connected to.
