One of the problems with SMS affecting user experience is the lack of fundamental security mechanisms. SMS messages are susceptible to spoofing, fraud, and spam. The lack of encryption threatens privacy and prevents them from being used to send sensitive content. One of the driving forces behind adopting RBM is overcoming these flaws, providing a better customer experience, and preserving a high level of trust. However, sender verification and encryption are dual-sided coins that can both enable and prevent scams and non-compliant content.

As rich media becomes omnipresent in messaging channels, CPaaS providers face increasing threats from spammers and accidental misuse. They need expertise and innovative solutions to ensure compliance and customer satisfaction.

To ensure service integrity and compliance, CPaaS providers must prioritize protecting their SMS, MMS, and RBM channels. These services occupy a unique position in the messaging ecosystem because of their omnipresence and status as standardized and regulated telecom services.

As RBM use becomes more widespread, robust security measures will be crucial to safeguard against potential exploitation by spammers and maintain compliance with regulatory guidelines. It is a common misconception that RBM is secure by design. As is discussed in Enea’s RBM handbook, security measures such as encryption and vetting can both boost and hinder end-user security.

While RBM’s rich media capabilities offer enhanced engagement opportunities, they also open up new avenues for abuse. Spammers may leverage these features to create more convincing and visually appealing scams, potentially increasing the effectiveness of malicious campaigns. Additionally, brands may inadvertently send non-compliant content due to a lack of familiarity with RBM guidelines or simple mistakes when utilizing rich media elements.

The rise of AI technologies presents both a threat and an opportunity in the rich media messaging landscape. Malicious actors can use AI to generate personalized spam content at scale, increasing the volume and sophistication of attacks. The velocity at which new and morphing threats can hit the ecosystem multiplies with each new iteration of AI technology. However, AI is also a powerful tool for defense. CPaaS providers should leverage AI-powered solutions that can dramatically increase the efficiency of security solutions. Only by partnering with experts on spam prevention who are investing in AI can CPaaS providers stay ahead of evolving threats while ensuring a seamless experience for legitimate business users.

It is essential to understand that AI is a technology, not a solution. It can complement and significantly enhance the capabilities of messaging firewalls, especially for rich media content where text-based filtering using fingerprints cannot be applied. It is never a separate capability since spam filters need to manage text and media in a single solution. The strong relationship between SMS, MMS, and RBM through regulatory frameworks, handset app support, and fallback options means that a single firewall solution should be used for all to ensure accuracy and efficiency.

Deep expertise in messaging threats and intelligence is needed to make AI useful for spam mitigation. Extensive knowledge of spammers’ tactics, techniques, and procedures is necessary to design AI tools that can accurately identify and counteract spam and build the datasets needed for training. Furthermore, AI tools require continuous evaluation and tuning to ensure accuracy, especially in a rapidly changing threat landscape. Expert insights are the foundation for that process.

1. Invest in Messaging Security to Protect Brands and Subscribers

Adequate and adaptive security becomes increasingly important as regulators and the financial sector increase pressure on communication service providers, including CPaaS providers, to protect consumers and businesses from fraud and nuisance messages. CPaaS providers must continue to protect their reputation, maintain customer trust, and ensure regulatory compliance. Increased use of rich media in messaging and AI in the hands of spammers makes the task significantly more complex. With the rise of sophisticated phishing attacks and fraud tactics, implementing robust security measures is crucial for mitigating spam and malicious content across SMS, MMS, and RCS channels. Ultimately, investing in messaging security enables CPaaS providers to build trust, optimize revenue, and position themselves as reliable partners.

2. Partner With Experts in Messaging Security and AI to Ensure Future-Ready Protection

CPaaS providers should partner with experts in messaging security to ensure compliance and protect profitability. They should deploy messaging firewalls that leverage AI to improve existing detection and filtering mechanisms. Rich media content, privacy concerns, and AI-generated spam raise the requirements for the capabilities a messaging firewall must possess. Using AI to automate the detection and filtering of spam boosts efficiency and enables real-time management of compliance breaches for rich media content. But, for AI to be helpful, it must be backed by expertise to train, monitor, and complement the solution. Not all security tasks are suitable for AI, and combining AI and human expertise offers the best performance and highest accuracy. However, developments in the AI field are happening very quickly, so CPaaS providers should ensure that they work closely with messaging firewall vendors who innovate and develop based on actual needs and leverage AI where it contributes to the overall solution.

3. Leverage Global Intelligence and Expertise for Proactive Security

Messaging security expertise and global threat intelligence are essential for CPaaS providers due to the rapidly evolving and complex nature of threats in the A2P messaging landscape. Spammers are extremely quick to find new ways to exploit messaging, adapt spam content, or hide it in media to avoid firewalls. Leveraging global insights from vast traffic volumes to provide actionable threat intelligence enables early detection and proactive defense against emerging threats. This global perspective is crucial for identifying new attack techniques, understanding regional variations in spam tactics, and maintaining compliance with diverse regulatory requirements. Using global expertise to make AI meaningful in messaging firewalls is a key success factor.

4. Use a Unified Firewall for Increased Protection and Improved Efficiency

CPaaS providers should utilize a single firewall for SMS, MMS, and RCS to enhance security, improve operational efficiency, and provide comprehensive protection across all messaging channels. The relationship between the telecom standards-defined services and the use of one another as fallback options means that with a unified messaging firewall, CPaaS providers can leverage intelligent cross-correlation techniques to detect and prevent fraud more effectively. This unified approach not only makes financial and operational sense but also enables the correlation of threats between different bearers, significantly improving detection and analysis capabilities.
