Email Security

CensorNet Email Security is a cloud based email security and backup service that scans both inbound and outbound email for viruses, phishing threats, content violations and spam.

Security – Incorporates multi-layers of security and provides inbound and outbound email protection across the whole organisation by removing email-borne malware threats and spam before the email is delivered to your mail server – thus improving bandwidth and increasing mail server resources.

Management – Backs up email for regulatory compliance for up to seven years and enables email access even if the local mail server has failed.

Reporting – Provides complete visibility on inbound and outbound messages for your domain(s). Audit allows for examination of the exact reason an email was delivered or rejected, including the conversation with the remote email server. Chart and table reports can be generated based on the rules triggered and actions taken for all inbound and outbound email.

Deployment – Zero upfront investment in hardware or software required. Quick and easy deployment by redirecting domain MX records to MailSafe cloud.

Increase security – Prevents accidental access to malware by removing infected email messages and attachments before they reach your network. Blocks phishing emails that appear genuine and redirects to quarantine.

Prevent data loss – Notifies instantly or blocks email messages that match content rules relating to confidential or sensitive information.

Increase up-time – Ensures business continuity in the case of local email server failure by allowing employees to use the MailSafe portal to read, reply, and compose emails.

Improve bandwidth – Blocking spam in the cloud means only clean email messages are delivered to the local network, reducing the amount of bandwidth and resources required on mail servers.

Rapid return on investment – Preventing malware outbreaks and reducing spam messages deliver an instant return on investment.

Low total cost of ownership – A simple licensing model based on the number of mailboxes to manage, easy deployment, and no hardware or software licensing requirements.

Reduce legal risk exposure – Use the SecureMail feature to send messages that are never stored on the recipients computer and are accessed through an encrypted portal. Use the rules engine to block email containing sensitive content and optionally backup all inbound and outbound email for later review.

The platform consists of the following main components.


The system works by redirecting the email for your domain by altering the MX (Mail eXchange) record (part of DNS). The MX record determines where email will be delivered so it is changed to point to our servers. The redirected email then flows through the CensorNet MailSafe cloud where it is filtered for spam, viruses and images, and optionally archived for safe keeping. Once the email has been filtered, it is sent on to your own email server which means you are only receiving clean email rather than spam as well. This helps to reduce the load on your email server and improve your bandwidth.

What is CensorNet Email Security?

CensorNet Email Security is an email management solution hosted in the cloud. By email management, we mean it provides a suite of features to help you more effectively manage email in your organisation. Email for your domain(s) is redirected to our servers before it is delivered to your local email server, such as Microsoft Exchange or Exim. These features include comprehensive anti-spam and anti-virus, one-click release from quarantine, archiving, reporting and webmail.

What is Software-as-a-Service?

Software-as-a-service is a method of delivering the software without needing to install hardware or software on the local network. The product is hosted in data centres on the Internet and the management of the product takes place by logging into a web site.

How is the initial cost of my requirements calculated and are there any ongoing costs?

Email Security is priced on the number of active mailboxes for your domain(s) and is billed annually in advance based on a minimum 12 month term. We do not charge for multiple domains, aliases or dormant accounts, so you only pay for what you actually use.

At the end of the 12 month period you have the option to renew again and the price will be based once again on the number of active mailboxes you have – which may have increased or decreased.

We also take into consideration the type of organisation (business, government, education, charity) and the geographic location. There are special discounts for purchasing multiple years in advance.
