Mobile communication has changed dramatically over the past decade—and so have the risks that come with it. Conversations happen across multiple apps, devices and networks, all of which often leave behind metadata and patterns that can be just as revealing as content itself.
In 2025, Sotera Digital Security reached an important turning point. In addition to providing unparalleled security for voice and text communications, the company committed to extending protection across more forms of communication, more layers of the mobile stack, and more regions around the world. The result is a broader mobile security ecosystem designed to meet different needs and risk tolerances without compromising on core security principles.
For many security-conscious individuals, the challenge is having truly secure protection while meeting their real-world communication and connectivity needs.
In 2025, Sotera expanded SecurePhone’s capabilities to support traditional voice calls and SMS messaging. This evolution allows SecurePhone users to communicate more easily with non-SecurePhone contacts while maintaining Sotera’s security-first design philosophy.
Rather than opening access indiscriminately, this update reflects a deliberate approach: expanding secure coverage into everyday communication channels without weakening the underlying architecture of the SecurePhone. The SecurePhone has evolved from closed network secure device into a more versatile, secure line that supports how people work and communicate.
Mobile security needs vary widely depending on how people communicate and the level of risk they face. The SecurePhone provides the highest level of security for voice and text communications, but users also rely on their commercial smartphones for internet access, apps, and everyday workflows.
With the launch of SecureShield in 2025, Sotera is now able to protect mobile traffic at the network level without disrupting how customers use their smartphones. SecureShield is a software defined private network designed to protect mobile IP traffic as it moves across the network. Using post-quantum encryption and advanced routing techniques, it helps reduce exposure to threats such as traffic analysis, metadata collection, and pattern-of-life monitoring—risks that exist beyond the device layer.
This layered approach enables organizations and individuals to choose the level of security that aligns with their operational needs.
In parallel with its product evolution, Sotera expanded its global presence in 2025 through the addition of new partners in more than 20 countries: Colombia, Peru, Mexico, Costa Rica, Guatemala, El Salvador, Honduras, Panama, Dominican Republic, Chile, Paraguay, Uruguay, Argentina, Brazil, Malaysia, Singapore, Philippines, Saudi Arabia, Qatar, Dubai, Spain and Egypt.
This growth reflects increasing global demand for mobile security solutions that can operate across borders, regulatory environments, and threat landscapes.
Global expansion is more than a geographic milestone—it’s a validation of Sotera’s value proposition in multiple markets around the world. By growing its partner network, Sotera is better positioned to serve customers wherever they operate.
Reflecting on the past year, Sotera’s leadership sees 2025 as a pivotal moment.
“As mobile communication continues to evolve, it’s clear that mobile security can’t follow a single model,” said Rick Boyd, president of Sotera. “Different users face different risks, and our focus is on expanding secure connectivity to provide best-in-class options aligned to their communication and security needs.”
This perspective shaped Sotera’s decisions throughout the year, guiding both product development and global expansion.
In 2025, Sotera expanded what mobile security means. By enhancing SecurePhone’s communication capabilities, launching SecureShield, and growing its global partner network, the company now protects more of the mobile ecosystem than ever before.
Looking forward, Sotera remains focused on building ways for protected devices and networks to interact safely with widely used communication tools.
