The Image Content Analysis (ICA) add on for Web Security protects employees and IT environments from inappropriate ‘Not Safe For Work’ (NSFW) images – including adult, offensive and extremist content.

ICA incorporates AI and deep learning technology to provide extremely high accuracy, eradicating false positives.

ICA enables powerful Acceptable Use Policy enforcement – without the need for human moderation – whilst protecting employees, avoiding legal liability, and maintaining company culture and brand image.

  • Prevent NSFW imagery from entering the environment
  • Identify users that are potentially misusing Internet (web) access
  • Detect and manage high-risk image and video content
  • Proactive, automatic enforcement of policy as and when required – with an audit trail to demonstrate action / protection

Simple Management

ICA is fully integrated within the Web Security service as an optional add on to the Censornet Cloud Security Platform. ICA scans all images and videos accessed online automatically, replacing any inappropriate content with a ‘safe’ symbol.

Legal Liability

In most countries employers can be held vicariously liable for the actions of their employees – unless they can demonstrate they have taken all reasonable steps to protect their people from a hostile working environment.

ICA protects organisations from harassment and offensive content claims – or even criminal charges if illegal content is involved – and ensures a safe workplace for everyone.

Brand Preservation

Companies spend exceptional amounts of time and money building a compelling brand and positive brand image. Negative press coverage can damage an organisation’s brand almost instantaneously but take an age to restore. ICA mitigates the risk of unwanted publicity.

Image Content Analysis is also available for CASB API Mode – scanning content of files uploaded to cloud storage applications including box, Dropbox, Google Drive, and OneDrive.

Image Content Analysis is also available as an add-on for Email Security scanning images in email messages and attachments.

After email, the web is the second most common vector for malware infection.

The Antivirus (AV) add on for the Censornet Cloud Gateway provides an optional additional layer of advanced malware protection at the network edge, stopping malicious code before it reaches the endpoint.

Gateway AV scans all accessed web content in real-time for malware with support for all file types known to be used to spread malware content – including executables, packed executables, archives, Office documents, flash files and MP4 video. The AV engine is updated hourly.

A multi-layer web security model protects users from advanced malware threats:

  • Layer 1 – uses URL filtering and online threat detection to identify malware before it gets to the device
  • Layer 2 – uses heuristics, emulation, and generic signatures to identify unknown malware that has not been seen previously (zero day malware)
  • Layer 3 – monitors file behaviour and blocks the file if it starts to behave maliciously
  • Layer 4 – file hashes are compared with a database of more than 1.6 billion known clean file hashes to reduce false positives

This optional add on provides additional reports by Active Directory Group including:

Top Web Categories by Group – The top Web categories visited by all users with the option to limit to a specific Active Directory group (direct membership).

Top Domains by User or Group – The top domains visited by users with the option to limit to a specific Active Directory group (direct membership).

Top Users or Groups by Time Spent – The top users by approximate time spent browsing, with the option to limit to a specific Active Directory group (direct membership).



“Censornet stood out because it was an exact match for our requirements. When employees leave the network, they are seamlessly protected when browsing online. Censornet Web Security was the only product in the market that could provide this solution for us.” “CensorNet has delivered the solution it promised and have gone above and beyond to ensure that it works with our business. It prevents issues before they happen by making sure employees are protected from malicious sites and activity online. We have had no security issues since we began using it.”

Mike Ryan, Infrastructure Manager

“We needed to allow the off-site users to access the internet without going through the VPN, as it really hindered connectivity. We wanted to ensure all users were as protected as possible. Censornet Web Security allowed us to do this.”

Hamish Ross, Senior IT Engineer
