Is RCS Business Messaging Secure?

The short answer is: Yes – RCS Business Messaging is more secure than traditional SMS due to verified sender profiles and encryption in transit. 

When evaluating the security of RCS, we can split the security aspect into two: The technical security (how is the data protected from hackers) and the Legal jurisdiction (Who has the right to access the data).

From a technical standpoint, RCS provides a much higher level of security for both the business and the end-user than standard SMS. RCS was built to solve the biggest security flaw of traditional SMS: the lack of authentication.

• Verified senders: The biggest security win with RCS is the Verified Brand Profile. RCS requires brands to be verified which means customers can see the company logo and a verified checkmark. This feature practically eliminates phishing and ensures your brand cannot be impersonated.

• Encryption in transit: RCS uses TLS (Transport Layer Security). This means your messages are encrypted as they travel from the gateway to the customer’s device. Even if intercepted on a public Wi-Fi or carrier network, the content remains unreadable to hackers (Note that this is encryption in transit and not E2EE).

• Anti-Spam intelligence: Advanced machine learning is used to scan for malware and fraudulent patterns before the message even reaches the device, keeping the channel clean for legitimate businesses.

Beyond technical safeguards, the security of any messaging platform is also linked to the legal frameworks. For some businesses, the security of the data is defined by who has the legal right to access it.

• The Google Jibe Infrastructure & GDPR: RCS Business Messaging is fully GDPR compliant. However, because messages must route through Google Jibe’s infrastructure for delivery, they fall under US jurisdiction (US Cloud Act). This means the 100% EU-only data sovereignty provided by our EU-setup for SMS and Email cannot be guaranteed for RCS at this time, as the global ecosystem currently relies on Google as a central hub.

• Lack of End-to-End Encryption (E2EE): Because messages must be routed through various hubs and aggregators to process rich features and interactive content, end-to-end encryption (E2EE) is technically unfeasible in its current implementation. The confusion about end-to-end encryption arises from privateconsumer RCS , which can offer E2EE for one-on-one chats.
