At a high level, RCS offers a richer messaging experience than SMS – and this includes its more robust security measures. This includes measures like encryption in transit (i.e., the encryption of data as it moves between a user’s device and services) and end-to-end encryption in some cases. This ensures that messages remain secure as they travel over networks.
RCS Business Messaging (also known as RBM) shares the same security framework as RCS, but RBM also includes an additional layer of protection focused on business verification, which helps establish trust between businesses and consumers. This verification process helps prevent spam and phishing attacks which are common in traditional SMS.
