Email Security

Dramatically reduce unwanted messages at the gateway with an array of integrated anti-spam and content control technologies managed through a single, unified interface.

Spam, or unwanted email, has become one of the largest side effects of the Internet, severely impacting email as a productivity tool. The increase in spam volume should come as no surprise as spam is a highly lucrative business. Spam profits are defined as revenues from sales of products or services generated from responses to spam, less the cost of sending spam. The cost of sending 10,000,000 messages is about the same as sending 100,000 messages. Assuming the response rate, profit margin per item and cost of sending spam remain constant, a spammer only needs to increase the volume of spam sent in order to earn more money.

The evolution of spam has had a direct impact on the email services delivered by Information Technology departments. It has breached the three essential security measures that must be present in order to provide secure email services; confidentiality, integrity and availability.

Enterprises have deployed firewalls to enforce network level security, but they have limited means of analyzing the actual content of the email that is transmitted. Only specific email appliances which use a cocktail of techniques are effective in the fight against spam.

Email security appliances sit in front of your email server and scan all incoming and outgoing messages for viruses, profanities, spam, etc. Having the appliance at the gateway reduces the load on your email servers and bandwidth and provides you with an extra layer of protection.
