Sparkle, a leading international service provider, announced the launch of STLS-AI (Symmetric Transport Layer Security for Agentic Artificial Intelligence) on November 12, 2025, a patent-pending innovation designed to establish secure, verifiable communication between autonomous AI agents. This new service utilizes a quantum-resilient approach, eliminating reliance on traditional certificates or centralized authorities to facilitate mutual recognition and authentication. Demonstrated live across transatlantic connections during the Global NaaS Event, STLS-AI addresses the critical need for trust and security as the AI agent segment—currently experiencing annual growth exceeding 40%—expands into increasingly complex digital ecosystems.
Sparkle Launches STLS-AI for Secure AI Communication
Sparkle has launched STLS-AI (Symmetric Transport Layer Security for Agentic Artificial Intelligence), a patent-pending service designed to secure communications between autonomous AI agents. This innovation addresses a critical need as AI evolves beyond simple prediction into agentic systems capable of planning, negotiating, and independent action. Live transatlantic demonstrations at the Global NaaS Event showcased STLS-AI’s capabilities, connecting AI agents across Dallas, London, and Northern Virginia, proving faster, safer, and verifiable communication is now possible.
The core of STLS-AI lies in its ability to establish trust without relying on traditional certificates or centralized authorities. This is increasingly important given the projected 40%+ annual growth of the AI agent segment—reaching potentially tens of billions of dollars by the end of the decade—and the need for secure, verifiable interactions between these multiplying intelligent systems. Sparkle builds on its prior quantum-safe solutions (QSI & QSO) by extending that security directly to AI “intelligence” itself.
Commercially available by the end of 2026, STLS-AI positions Sparkle as a key “trust broker” within the emerging AI-driven economy. Proof-of-concept opportunities are available now for partners and customers. Daniele Mancuso, Sparkle’s Chief Marketing & Product Management, highlights that the service lays the foundation for
STLS-AI: Enabling Trust in Agentic AI Systems
Sparkle has launched STLS-AI (Symmetric Transport Layer Security for Agentic AI), a patent-pending service designed to secure communication between autonomous AI agents. This innovation addresses a critical need as AI evolves beyond simple prediction to agentic systems – those that plan, negotiate, and act independently. Recent market analysis shows the AI agent segment is experiencing over 40% annual growth, projected to reach tens of billions of dollars by decade’s end, highlighting the urgency for robust, verifiable AI-to-AI communication protocols.
STLS-AI distinguishes itself by eliminating reliance on traditional certificate authorities, enabling agents to directly identify and verify each other. Live transatlantic demonstrations—connecting agents in Dallas, London, and Northern Virginia—showcase faster, safer communications. This is achieved through symmetric encryption, ensuring both data protection and agent identity verification. Building on Sparkle’s existing Quantum Safe services (QSI, QSO), STLS-AI extends quantum-resistant security from network level to the AI intelligence itself.
The implications are significant for businesses developing or integrating AI agents. STLS-AI establishes a “trust fabric” allowing secure interactions across digital ecosystems, essential for autonomous systems operating without human oversight. Proof-of-concept opportunities are immediately available, with commercial availability slated for late 2026. Sparkle positions itself as a key “trust broker”
Expanding Quantum-Safe Security Services with STLS-AI
Sparkle has launched STLS-AI (Symmetric Transport Layer Security for Agentic Artificial Intelligence), a patent-pending service designed to secure communications between autonomous AI agents. This innovation addresses a critical need as AI evolves beyond simple prediction to agentic systems capable of planning, negotiating, and independent action. Live transatlantic demonstrations, connecting Dallas, London and Northern Virginia, proved STLS-AI’s ability to deliver faster, verifiable communication—a key step towards building trust in increasingly complex AI interactions.
This new service differentiates itself by eschewing traditional certificate-based authentication, instead focusing on direct, verifiable agent-to-agent recognition. With the AI agent market projected to grow at over 40% annually, reaching tens of billions of dollars by decade’s end, secure communication is paramount. STLS-AI builds upon Sparkle’s existing quantum-safe offerings—QSI and QSO—extending that security “from the network to the intelligence itself,” establishing a new layer of trust for AI ecosystems.
Commercially available by late 2026, STLS-AI positions Sparkle as a “trust broker” within the burgeoning AI-driven economy. Proof-of-concept opportunities are immediately open for partners and customers. This isn’t merely about data protection; it’s about enabling autonomous systems to prove their identity and collaborate securely, fostering accountability
