SMSFW stands for Short Message Service Firewall
An SMS firewall is a security solution that helps in filtering and blocking unwanted or malicious SMS traffic from reaching mobile devices or phones. It is a security tool meant for protecting mobile networks from unsolicited SMS-based messaging attacks such as SMS spoofing, SMS flooding, SMS faking, and spamming.
An SMS firewall works by intercepting and analysing all SMS messages that are sent or received by the mobile network. It uses various techniques such as content filtering, sender verification, traffic monitoring, and policy enforcement to classify and block messages that are harmful, fraudulent, or unauthorised. It also allows the mobile network operator to monetise the legitimate A2P (Application-to-Person) SMS traffic by preventing grey routes and revenue leakage.
An SMS firewall can provide many benefits for mobile network operators and subscribers, such as:
- Enhancing network security and performance by preventing malicious attacks and reducing network congestion.
- Increasing customer satisfaction and loyalty by improving SMS service quality and preventing spam and unwanted messages.
- Generating new revenue streams by enabling A2P SMS monetisation and creating new business opportunities with SMS aggregators and service providers.
