The launch marks a key step in SEALSQ’s strategy to embed quantum-resistant security directly into next-generation robotic systems, addressing emerging risks as quantum computing advances. WISeRobot.ch serves as the central hub for the WISeRobot ecosystem, outlining product capabilities, deployment use cases, partnership opportunities, and a multi-phase development roadmap. The platform integrates WISeKey’s digital identity and cybersecurity expertise with SEALSQ’s post-quantum semiconductors and PKI infrastructure to enable trusted, secure human–machine interaction. WISeRobot Stood Out at CNBC Davos as a Highlight of the Day (January 2026) The announcement builds on WISeRobot’s debut at the World Economic Forum in Davos in January 2026, where the platform was featured at CNBC Davos and at a SEALSQ–WISeKey roundtable. These demonstrations highlighted the system’s ability to engage in natural human interaction while operating within a secure, identity-based framework. At CNBC Davos, WISeRobot truly stood out as one of the highlights of the day. By interacting naturally with speakers and attendees, it quickly moved people from initial curiosity to genuine engagement. Participants asked questions, shared jokes, took photos, and began treating the robot less like a machine and more like a conversational partner. What was most striking was the shift in energy and body language: hesitation gave way to smiles, laughter, and meaningful dialogue. WISeRobot became a catalyst for conversations around AI, trust, and the future, offering a tangible example of how human-centric AI can enhance human presence rather than replace it.

The demonstration illustrated secure digital identity, protected communications, and trusted machine-to-machine interactions in real time. SEALSQ is currently advancing this work, focusing on embedding quantum-resistant algorithms and hardware-based roots of trust at the silicon, firmware, and system levels. The objective is to establish a security foundation for AI-driven and autonomous systems deployed in critical sectors such as government, healthcare, and smart infrastructure. Carlos Moreira, Chairman &amp; CEO of SEALSQ, noted, “As robotics and AI are rapidly becoming part of our critical infrastructure, ensuring long-term security is essential. By testing post-quantum technology in robotics and bringing this first P.O.C., our aim is to demonstrate how trust, security, and human-centric values can be embedded into intelligent machines from the very beginning.” WISeRobot.ch: A Dedicated Platform for the Future of Human-AI Collaboration The WISeRobot roadmap includes continued development of conversational AI capabilities, expanded enterprise applications, and deeper integration of post-quantum security technologies. <a href="https://www.globenewswire.com/Tracker?data=SQ4OWA-QFLeXl7pTm3XR0CoAIJBzpEkub5JzE0U-YyF1sq8dHkZbbVjmzmXhTnxxyKKmYWmH8y7fVWtd-1T9VA==" rel="nofollow" target="_blank" title="">WISeRobot.ch</a> platform serves as the central hub for the WISeRobot ecosystem, providing information on product capabilities, deployment use cases, partnership opportunities, and the company’s multi-phase technology roadmap.
