Email Security Software
CanIt-PRO protects users from seeing other users data, settings and incidents. A regular user will not be able to adjust, manage or otherwise interact with any settings or information on the system that does not relate to their account. Administrators of the system are granted access to manage these settings on the users' behalf.
CanIt-PRO provides the ability for end users to manage their own settings and options. They can manage how mail is detected as spam, if it is to be automatically rejected (discarded), held in a trap or tagged and passed through. Users also can manage their own rules for whitelisting, blacklisting, content filtering, DNSBLs, Bayesian settings and so on. Administrators can set permissions to restrict the settings users have access to.
In specific cases other users can be granted access to manage another user's settings. This is done by explicitly indicating which accounts a user has access to manage. This is done by the administrator of the system.
Authentication and Authorization
CanIt-PRO provides built-in capabilities to authenticate end users based on the following methods:
This authentication can be configured on a per domain and even per sub-domain basis.
In addition CanIt-PRO provides a flexible e-mail security infrastructure to allow for additional authentication and other integration methods to be implemented. These include:
CanIt-PRO provides detailed reports about the mail that is has processed. Reports can be generated for the system as a whole or for specific domains. These reports allow Administrators and Site Administrators the ability to see how the system is performing. Reports summarizing the following information are available:
These reports can be generated on an as-needed basis or can be configured to be automatically generated from within the CanIt-PRO anti spam program and emailed as PDF attachments.
