roadNet's SMS Firewall solution provides mobile operators with a safe, spam-free roaming and messaging environment that their subscribers can trust, while reducing complaints caused by unsolicited messages. It filters Mobile Originated (MO), Mobile Terminating (MT) and Application traffic (SMPP) messages, and adds real-time intelligent threat detection, blocking management with definable blocking rules and configurations, alarm triggering and load balancing.
The importance of an SMS firewall cannot be stressed enough in today's market, because it is the ideal SMS anti-fraud solution for mobile operators. It is intended to protect the operator's network and the operator's subscribers against unauthorized SMS traffic, whether that traffic is application-originated SMPP traffic or transit mobile-originated traffic. In addition to that, an SMS firewall supports anti-spoofing and anti-faking filtering and detection capabilities, so messages that disguise their true source can be identified and stopped before they reach subscribers.
The most crucial idea behind implementing an SMS firewall is to prevent unsolicited message sending, or spam messages from content providers. It is also worth saying that a well-built SMS firewall delivers high-performance and scalable protection that keeps pace with modern safety requirements, even as messaging volumes on the network grow.
In brief, an SMS firewall provides significant base protection against SMS spam, and it blocks malicious signaling attacks, suspect sources of messages, unusually high SMS volumes and inconsistent SMS traffic in general. The firewall uses several metrics to decide whether each specific situation should be treated as spam or not. The volume of message traffic is definitely one of the factors that influences the decision, but the whole process has become automated over time, so technicians are only required to monitor it rather than interfere in the finer details of every message.
An SMS firewall also enables operators to actively monitor application-originated SMS in order to prevent fraud and spam. This is achieved by monitoring all SMS texts originated by local subscribers, giving the operator full control over the SMS messages moving through the network. Moreover, that control and monitoring allow the operator to enforce proper restrictions and protect their messaging revenue — a key concern as more and more business traffic flows over A2P channels. The outcome can be very satisfying: spam messages are reduced, which improves the SMS service and keeps subscribers happy.
Why use an SMS firewall?
An SMS firewall allows you to eliminate grey routes, or undesired routes. This way you can gain full control of SMS traffic in your network and get rid of the spam and unwanted messages that could disturb or slow down your business processes and undermine legitimate messaging. Ultimately, this makes your operation more efficient and more effective, helping you reduce costs and maximize revenue at the same time.
A capable SMS firewall also lets operators benefit from further features such as SMS content filtering, global title filtering, anti-spoofing and anti-faking. Together, these controls give operators the transparency and security their networks need, protecting both subscribers and the messaging revenue that runs across the network.
