Filter the threats, Deliver the trust

Safeguarding telecoms with SMS firewall

Telogo SMS firewall safeguards the telecom operator's receiving side by preventing harmful messages from entering the network, thereby protecting subscribers from spam and fraud. It helps telecom operators maintain a secure messaging environment, avoid revenue loss from grey routing, and improve the overall user experience by delivering only trusted and secure SMS traffic.

Spoofing of GT

To counter GT spoofing, telecom operators use transparent safeguards. These involve advanced firewalls or security layers that monitor and authenticate requests in real time. If a request to access the network is made using a spoofed GT, the safeguard system identifies the fraudulent attempt by validating the source and legitimacy of the request before it is processed.

“Many SMS firewalls have basic spoofing detection that focuses on identifying discrepancies in GT information but may lack in-depth verification or real-time analysis.”

Real-Time Verification

Telogo's solution performs real-time checks and anomaly detection on GT requests, offering more immediate and effective protection against spoofing.

Enhanced Security Protocols

Utilizes advanced encryption and secure transmission protocols to protect GT information, which is more robust compared to standard practices.

Comprehensive Reporting

Provides detailed logs and audit trails, which are crucial for identifying patterns and conducting security audits, offering a more thorough approach to managing GT spoofing.

Virtual IMSI and VLR to Safeguard

In mobile networks, IMSI (International Mobile Subscriber Identity) and VLR (Visitor Location Register) are vital components used to authenticate and manage subscribers, especially during roaming. Attackers often target these elements to steal subscriber information or initiate fraudulent SMS routing.

Telogo SMS Firewall protect its subscribers by Virtual IMSI and VLR

Virtual IMSI Protection

Telogo's firewall employs virtual IMSIs to protect subscribers real identities. By masking the real IMSI with a virtual one, the system ensures that even if attackers intercept the message, they cannot access the actual IMSI. This prevents fraudsters from launching identity theft or initiating unauthorized transactions.

Virtual VLR Protection

When subscribers roam across different networks, their details are stored in the Visitor Location Register (VLR). Telogo’s firewall uses virtual VLR technology to isolate and protect subscriber information, ensuring that their data remains secure even when interacting with foreign networks.

Dynamic Switching

Virtual IMSI and VLR can be changed dynamically, making it difficult for attackers to target specific users over time, thus enhancing overall network security. This adaptive approach ensures that subscribers remain protected even as threat patterns evolve.

Enhanced Roaming Security

This feature is particularly beneficial during international roaming, where threats of identity theft or unauthorized access are higher. Telogo’s firewall ensures that both the home and visiting networks are protected from external attacks.

International Routing

This is a critical area of security concern, as international traffic is often vulnerable to grey routing, SIM box fraud, and call masking.

unauthorized international routing can result in revenue loss and expose the network to security risks.

it compromises subscriber trust by exposing them to potential security threats and fraud, while also degrading service quality due to unreliable message delivery and network performance issues.

How Telogo's SMS Firewall handles international routing

Grey Routes

It involves routing SMS traffic through unauthorized or unregulated channels, bypassing legitimate gateways. Telogo’s SMS firewall actively identifies and blocks such unauthorized routes by analyzing traffic patterns, origins, and destinations. It ensures that only SMS traffic routed through authorized international gateways is accepted.

Identifying Unauthorized Content

Telogo's firewall is equipped with deep packet inspection (DPI) and pattern recognition algorithms that scan the content of incoming SMS messages. If the content appears suspicious or violates network policies, it is flagged and blocked.

Real-Time Route Monitoring

The firewall continuously monitors international routing traffic to detect irregularities. Whether it's a sudden spike in message volume from a suspicious source or an abnormal routing pattern, the system flags the issue for review and takes appropriate action.

Blocking Fraudulent International SMS

By filtering out phishing URLs, spam, and fraudulent international SMS, Telogo ensures that malicious content does not reach subscribers, protecting them from scams and cyberattacks.

Telogo Firewall for your every business need

Integrate Machine Learning into Spam Filters

Modern SMS firewalls enhance traditional spam prevention by integrating machine learning to automatically detect suspicious patterns. This approach, supported by AI and real-time threat intelligence, offers robust protection against phishing, spam, and A2P abuse, ensuring stronger network security and policy compliance.

Cloud-Based Managed SMS Firewalls

A cloud-based, fully managed SMS firewall enables effective filtering of international messages, providing MNOs with 24/7 control over rules, parameters, and reporting through an online portal. Businesses gain full visibility and control via a web-based interface, ensuring high availability and robust service.

Establish a Fraud Response Framework

A defined fraud response framework is crucial for quickly addressing SMS threats. This includes a system that alerts subscribers to potential risks and offers businesses options to allow, block, or ignore suspicious messages based on risk assessment.

Regularly Update Screening Rules

Regular audits and updates to SMS firewall rules are essential to address emerging threats. Enhancing keyword, phrase, and sender number filtering helps prevent phishing, malware, and spoofing, ensuring compliance with GSMA standards and robust defense against fraud.

Introduce a Fraud Reporting Shortcode

Offering a shortcode for subscribers to report suspicious messages creates a direct feedback loop, boosting subscriber trust and strengthening the overall security of the network.
