TECHNICAL BENEFITS

SaaSexperts provides a managed service that operates at the Internet level. Our web-based solutions ensure that clients don't need to download or manage software on their PC or server. The service provides a first line of defense against all email threats including viruses, spam, malware, denial of service attacks and directory harvesting. Businesses are further protected against legal action with image and content filters.

100% Viruses removal with 0% false positives

The SaaSexperts 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, analyze and release tested updates to the anti-virus engines leaves organizations 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, the SaaSexperts employs Zero Hour and heuristic filters to seek out new, unknown viruses through additional mail scanning.

99% spam removal with 0.0003% false positives

With spam levels regularly being measured at between 65 and 90 percent, the SaaSexperts 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 organizations recognize the distress that can be suffered by users who innocently open email to find distasteful images attached. Increasingly, employers recognize that they have a duty of care to minimize these incidents and consequently, SaaSexperts 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 organizations 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 Phishing

Dark Mail is a phenomenon whereby message traffic is submitted by an attacker to numerous email addresses in the hope of finding a valid target. A key trait of such an attack is that the majority of these email addresses are non-existent. In all likelihood, these attacks are happening to most organizations 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.

SaaSexperts release 3.1.0 adds support to detect and manage these attacks. Three levels of control are provided that enable the filtering service to identify and detect dark mail recipients:

• LDAP (Secure): Providing the ability for the filtering service to connect to an organization’s directory, e.g. Active Directory, and periodically synchronize valid recipient addresses for filtering
• Pattern Matching: Ability to configure intelligent address matching filters to identify valid and invalid recipients
• White list management: Capability to upload and merge email address recipient information into the service.
• White list management: Capability to upload and merge email address recipient information into the service.

Given that every organization is different, the multiple levels of control allow organizations to pick the solutions that work best for them.

Uniquely, the service also protects organizations from the security threats associated with the divulgence of email address through DHA (Directory Harvest Attacks), by transparently consuming emails within the service, rather than publicly rejecting invalid emails. Reporting is provided to indicate the level of Dark Mail filtering that is taking place. This includes the ability to report on key Dark Mail attacks, including DHA (Directory Harvest Attacks) and DSA (Dictionary spam Attacks).
