In order to be able to cope with the ever increasing resourcefulness of spammers from all over the world, you will need to be able to respond quickly to changing tactics and spam techniques. With the increasing threat of SMS spam, solid spam protection will be an essential customer care asset. The TextPass™ Firewall has a rule-based routing and filtering engine that allows for immediate response to new spam methods. This can be done on-line, without any service interruption.

TextPass™ supports advanced SMS filtering and blocking, while offering enhanced load distribution and throughput control. This provides overload protection from (inter)national SS.7 and IP message originators. Only with the TextPass™ Firewall you are able to protect your SMS infrastructure from incoming unwanted SMS messages.

The SS.7 routing and screening capabilities of TextPass™ are based on user definable rules that filter (or route) any incoming SMS message. A message can come from an SMSC, MSC/STP (traditional SS.7 or SIGTRAN) or from an SMS application (TCP/IP). For example, with TextPass™, you can monitor and screen all traffic coming from or going to your own SMSCs. However, even more important for spam-filtering, TextPass™ can handle all incoming MT messages coming from other national or international mobile networks, as depicted in the diagram below.
