Spam has reached unprecedented levels. Threats to security and disruptions caused by Spam, Viruses, Worms, Trojans, Phishing and Directory Harvest Attacks are seriously impacting on the security of businesses and organizations worldwide and the performance of their business lifeline - email.

How It Works

The system works through a security network that processes email and only delivers email you want to read down to your PC or server. Every message going into or out of your mail infrastructure is scanned for dangerous content.

Simply put, email is sent to you, scanned by CTG Email Defender servers then continues on to you and vice versa, you send out emails, it is scanned and then goes to the receipient

Security

Malware Scan - The first step in the process is a malware scan - this is where we determine if the message itself is valid and if any of the attachments are acceptable. If necessary the message is disarmed and then forwarded to the virus scanners.

Virus Scan - Up to six different virus scanning engines to determine if any of the attachments contain viruses. If we find a virus we will comply with your policy (delete, disinfect, quarantine) or we can silently dispose of the message.

Spam Scan - Here we pass the message through thousands of tests to determine if it is a SPAM or a valid/clean email. Because of the number of anti-spam techniques used in this process we average 98% spam identification with less than 0.000004% false positive ratio (legitimate messages treated as junk mail).

Content Scan - This is the most comprehensive portion and the most flexible because it includes the ever evolving message intelligence part of the service. We can determine if messages contain adware or spyware, if they are "phishing" with fraudulent content, if they contain adult or foreign content not suitable for your users or if they are simply things you wish not to read.

As you can tell, the system is very flexible to give you the level of scrutiny you need to process your email. Instead of spending your time analyzing each message you can establish rules for yourself, your department or your entire company and have them applied automatically and reliably.
