TRUSTmanager ™
You can now automatically check the reputation of all connecting SMTP hosts against a constantly updated database of reputation scores provided by Clearswift. The host is then evaluated for previous spam related activities and awarded a "reputation score". The TRUSTmanager score, ranging from zero (a recognised spam source) to 100 (indicating no previous spam-related activities) can be adjusted to trigger at differing levels to suit the needs of individual organisations.
How it works
Clearswift’s TRUSTmanager is a community-based feedback loop. Its strength comes from the experiences of Clearswift’s customers.
TRUSTmanager observes every IP address that connects to MIMEsweeper email appliances. Every 15 minutes statistics are posted to Clearswift with information about each IP address such as:
- How many messages have come from an IP address
- How many spam messages
- How many non-spam messages
- What violation occurred / which filter was triggered
- Whether good or rejected
- Is it a virus sender
- Sender Domain
TRUSTmanager uses this snapshot and historic information to calculate a Reputation Score on IP addresses. It can then categorize an IP address into “reputable or non-reputable”. Based on this information gathered from a wide source, TRUSTmanager queries the score of each IP address as it makes a connection to your email appliance, therefore killing any non-reputable connections (and spammers) at source.
Flexible
TRUSTmanager queries all connections by default. However, if desired, it is possible to override. There are global whitelists within TRUSTmanager, so that you can correct and whitelist companies that your organization knows and trusts (e.g. Your managed service provider or ISP).
TRUSTmanager ensures that the volume of traffic hitting your actual spam engine and content filter is massively reduced, allowing your email appliance to get on with its job effectively.
Benefits
-
Stops Spam at source
Trustmanager works at the connection level, preventing spammers and malicious traffic even entering your network. Offering additional layered protection, it is the first layer of defense against spammers.
-
Accuracy
TRUSTmanager’s community-based approach, which uses information from thousands of email appliances, as well as its address reputation ranking system, ensures that you can trust its decision. This means that while connections from sources that could compromise your system are stopped at source, emails from trusted internet sources are allowed through.
-
Saves on Resources
Emails with malicious intent from third parties can result in compromised bandwidth and denial of service on your gateway mail server. By eliminating these threats at source your organization saves bandwidth and system resources, enabling your system to be used as it should, for legitimate business messaging.
-
Lets your email appliance do its job
The MIMEsweeper email appliance provides in-depth content and spam filtering as well as anti-virus protection. By stopping spam at source, TRUSTmanager enables the email appliance to concentrate on protecting your organization from inbound and outbound threats such as confidentiality leaks, loss of intellectual property, employee harassment and zero-day virus outbreaks.
-
Saves administration time
IT administrators have increasing demands on their time. The automated nature of TRUSTmanager means that there is no administration intervention or maintenance required, freeing up the IT department’s time and resources to concentrate on other business critical issues.
-
Dynamic Protection
TRUSTmanager statistics are collected and posted every 15 minutes ensuring an accurate view of traffic on the internet at any one time. The activities and profiles of spammers change at an alarmingly frequent pace. TRUSTmanager ensures that your organization has up-to-date protection.
