Symsoft SMS Firewall is a versatile solution that intercepts and filters incoming messaging traffic. Symsoft SMS Firewall can drive revenue from enterprise messaging customers by blocking excessive traffic from operators that do not pay termination fees, and also block spam and fraudulent messages to increase service quality for subscribers.
Enterprise messaging, or application-to-person (A2P) messaging, presents a way forward to maintain and grow the operator messaging business. Enterprise messaging means the use of text messaging by organizations to target customers with messages related to business and customer services, marketing, entertainment and an array of other information. Such A2P messages are more lucrative per message than ordinary person-to-person (P2P) messaging. However, as opposed to P2P messaging there is no guarantee that an operator controls and earns revenue for A2P messages sent to its subscribers.
Having recognized the opportunity, operators must overcome certain challenges to ensure and maximize their presence within the enterprise messaging market. Such challenges include:
- preventing SMS service providers and aggregators from delivering messages through ‘gray’ routes that bypass the operators’ billed routes,
- eliminating malicious and spam messages to subscribers, thereby protecting the enterprise messaging channel value by ensuring that subscribers continue to trust and readily accept such messages.
Failure to address these challenges head-on can result in substantial loss of revenue, additional customer care cost, as well as a real risk of brand damage and customer churn.
Symsoft SMS Firewall gives operators the ability to control incoming traffic to protect their customers from spam and malicious traffic, and to steer A2P and M2M traffic to operators that give proper compensation for all messages that are delivered.
Symsoft SMS Firewall Capabilities
Advanced Message Filtering
Operator revenues suffer when unwanted messages are sent to its subscribers. Customer satisfaction decreases, and the operator itself is often left without compensation for the delivery of a message. Symsoft SMS Firewall provides the ability to control incoming traffic with its extensive and highly configurable filtering capabilities. Messages are examined using a versatile rule-based logic to determine whether they will be delivered to a subscriber or not. An array of parameters can be inspected by Symsoft SMS Firewall, including the message content itself, to block messages from certain sources and messages containing suspicious links and telephone numbers. It can also be used to block A2P and M2M traffic from operators that do not pay termination fees while allowing regular subscriber traffic from the very same operators.
Active Prevention of Faking
Due to the popularity of SMS, many senders use subversive methods to avoid paying for the messages they send. This leads to revenue loss for the receiving operator. Illicit senders of SMS sometimes use a method called SMSC faking to be able to send messages free of charge. With this method, the sending SMSC uses a fake address when transmitting messages to avoid being charged termination fees by the receiving network. Symsoft SMS Firewall detects and intercepts messages sent from SMSCs that fake their addresses. Detection takes place before the delivery so that no messages from such SMSCs reach their destination.
Message Quota Control
Message flooding is another challenge facing operators. Excessive amounts of incoming messages can cause customer dissatisfaction and network overload. To prevent message floods from foreign network, Symsoft SMS Firewall can be configured to enforce quota controls. The quota control feature keeps track of the number of incoming messages and automatically blocks traffic if there are too many messages arriving from a certain MSISDN. Repetitive content from a single origin can also be filtered to effectively prevent spam.
Virtual SMS Firewall Functionality
Symsoft SMS Firewall allows operators to consolidate their SMS operations for multiple countries in one messaging node. To support consolidation, a single hardware cluster can operate several virtual firewall nodes, each with its own configuration, including global title and routing profiles. This allows for services to be separated by territory, service, type, volume or service level.
SIM Farm Filter
Another threat to the business of operators is SIM farms, that use bundles with large or unlimited numbers of text messages to distribute enterprise messages. Symsoft SMS Firewall can efficiently block traffic from such players through traffic analysis.
Active blocking of traffic from SMSCs that fake their identity
Advanced message filtering based on parameters such as sender, recipient, and message content
