Compliant Email Archive

Reduce email data risks, optimise storage costs, and improve productivity.

Analysis has shown that as much as 60% of business data is stored in email – and much of it exclusively (Source: IDC).

The Compliant Email Archive from Censornet captures and stores every message sent or received in a separate, secure, tamper-proof database in the cloud. Archived messages are de-duplicated, compressed, indexed and encrypted.

An intuitive search interface – accessible from any device – allows IT, HR, and end users themselves, to quickly find emails using multiple search criteria. Privileged users can rapidly search all mailboxes, or selected mailboxes, to respond to internal or regulatory requests.

  • Cost effective – licenses are only required for active users
  • Storing messages on a separate server can reduce premium mail server storage costs by up to 75%
  • Messages and attachments are fully indexed for lightning fast search
  • Users can search for and restore lost or deleted emails – without calling the helpdesk
  • Retention control automatically deletes messages as they age with the option to store messages indefinitely
  • In the event of a primary email service outage users have access to historic email via a web interface, accessible from any location and any device
Email Encryption – Censornet SecureMail

Censornet SecureMail is an add-on to Email Security and provides a simple, yet effective, solution for user-based encryption of specific messages.

Adding a customisable keyword to the start of the email message subject sends a message containing a secure link to the recipients that log in to a secure website to view the contents of the message.

SecureMail complements the policy-based encryption capabilities integrated within Email Security, with the ability to enforce the use of TLS for specified domains, as well as to use Opportunistic TLS for all messages – falling back to non-encrypted connections only if the receiving email server does not support TLS.

Advanced Email Sandbox

Add an extra layer of enhanced protection to Email Security.

The optional Advanced Email Sandbox protects against today’s evasive zero-day threats by providing a highly scalable and powerful environment to run in-depth, sophisticated analysis of unknown or suspicious programs and files.

The Advanced Email Sandbox service adds a powerful layer of protection to Email Security, alongside multiple tier-1 signature and behaviour-based antivirus (AV) engines. The Sandbox service analyses suspicious files in depth, detonates payloads in a contained virtual environment, scrutinises their behaviour, and identifies malicious intent.

Sandbox technology provides advanced threat protection and zero-day exploit detection by:

  • Leveraging purpose-built, advanced machine learning algorithms, aggressive behaviour analysis, anti-evasion techniques and memory snapshot comparison to detect threats
  • Helping uncover malicious files including polymorphic and other threats designed for undetectable targeted attacks
  • Fully integrating within Censornet Email Security for analysis of email file attachments with support for a broad range of file types.

Censornet’s Advanced Email Sandbox is a cost-effective sandbox solution for protection that goes above and beyond that provided by standard antivirus engines.

What Our Customers Say

Fever tree logo inverted
While we are all away from the office, the ability to easily measure productivity from the Censornet dashboard is great.

This also means we are able to audit outgoing communications to ensure no information is leaving the business that shouldn’t, and follow up if any suspicious requests are made. From an inbox perspective this means the correct categorisation of emails, and a huge reduction in spam making it to employees, which is great news for our staff who can now actually trust what’s coming in.
Mayur Mistry, Head of IT Operations Fever-Tree
While Microsoft has basic security functionality, we needed more sophisticated security tools to protect our employees, but also at the right price.

Censornet gives us advanced security and also has a far more personal and specialised security service.
Julian Daniel, Head of IT, Hallmark Hotels
