Multi-Layered Protection

To protect the full breadth of your network, Cetrom takes a multi-layered approach to keeping dangerous viruses and spam emails safely at bay.

Reverse DNS

Cetrom uses reverse DNS lookups to locate email servers and verify their validity

Cetrom uses reverse DNS lookups to locate email servers and verify their validity.
If we find an illegitimate server address, we prevent that server’s emails from ever reaching your system.

 

Blacklisting

Cetrom blacklisting is an access control system

As it applies to spam, “blacklisting” is an access control system that automatically builds lists of potentially harmful users, programs and network addresses. When you have Cetrom Email, we monitor the internet for you, identify the spammers and "blacklist" them for good.

 

Profiling

Cetrom profiling automatically flags dubious communication and filters harmful emails

Spammers and “malware” developers constantly change their tactics to outsmart weaker detection systems. But with Cetrom, you’re always one step ahead of the bad guys. We work constantly to identify the specific traits of new spam emails. This “profiling” automatically flags dubious communication and filters harmful emails, while letting legitimate communication pass through safely.
