SurfControl utilizes the Virtual Learning Agent (VLA), a content recognition tool that uses artificial intelligence with neural networks to scan messages and protect businesses from confidential data loss. The VLA can be trained to recognize an organization's unique critical documents, and then effectively control their distribution. This is not the same as Bayesian filtering however, please check Bayesian article for more details.
-
MailMarshal uses a SpamCensor engine, which encorporates both Bayesian and Heuristic techniques.
- Automatically adds email recipients to whitelist.
- Automatically imports Exchange contacts to whitelist.
- Automatically puts any mail from a new sender into a separate folder.
- Supports identifying for example German, French or Italian spam, using either foreign keywords (ready configured) or automatically learning.
- Uses Online Central Checksum Service ($149/year) instead of static signatures
