CensorNet MailSafes' protection provides a first line of defence against all email threats including viruses, spam, malware, denial of service attacks and directory harvesting. Organisations are further protected against legal action with image and content filters.

Protection process
Viruses (100% removal with 0% false positives)
CensorNet MailSafes’ core anti-virus solution comprises multiple best of breed identity based engines, which are critical in the detection of viruses. However, as mass outbreak viruses tend to replicate and distribute at such high speed, the time taken by identity based anti-virus vendors to capture, analyse and release tested updates to the anti-virus engines leaves organisations exposed to the threat of virus infection for a period of time. This window has been dubbed the ‘Zero Hour’ syndrome. To meet this challenge, CensorNet MailSafe employs Zero Hour and heuristic filters to seek out new, unknown viruses through additional mail scanning.
Spam (99% removal with 0.0003% false positives)
With spam levels regularly being measured at between 65 and 90 percent, CensorNet MailSafe has invested heavily in technology to manage the sheer volume of unwanted email being delivered. Careful attention to connection management and integration of multiple best of breed filters has led to blocking the maximum quantities of spam with the lowest possible rate of false positives.
Pornographic Images
Many organisations recognise the distress that can be suffered by users who innocently open email to find distasteful images attached. Increasingly, employers recognise that they have a duty of care to minimise these incidents and consequently, CensorNet MailSafe provides a filter specifically to address image analysis.
Encryption
The Managed Encryption Service provides an open standard encryption mechanism with no hardware or software purchase or maintenance required. Historically, reliable encryption has been unachievable for many organisations due to many interrelated issues – notably complexity, inoperable standards and, more recently, the threat of IPR leakage and malware infiltration through un-scannable encrypted channels. Managed Encryption Services are provided using Transport Layer Security (TLS), a transparent mechanism for encrypting data on a peer-to-peer basis, such as between messaging servers.
Dark Mail
Dark Mail is a phenomenon whereby message traffic is submitted by an attacker to numerous e-mail addresses in the hope of finding a valid target. A key trait of such an attack is that the majority of these e-mail addresses are non-existent. In all likelihood, these attacks are happening to most organisations on varying scales, however these nefarious activities tend to go un-detected, thus the term Dark Mail. If left unchecked, the attacks can scale to levels that cause extreme resource usage, message delays, black list outages and potential security breaches.
