SEALSQ Launches End-to-End Quantum Security Stack and Forecasts 50–100% Q1 Growth
SEALSQ Corp launched its Quantum-Resilient Vertical Security Stack, offering end-to-end post-quantum protection from silicon Root of Trust to cloud orchestration for quantum computing infrastructures. The company pivoted from a full Quobly acquisition to a minority stake, invested in EeroQ, and forecasted Q1 2026 revenue growth of 50–100% YoY.
1. Launch of Quantum-Resilient Security Stack
SEALSQ is ready to deliver its Quantum-Resilient Vertical Security Stack, featuring hardware-anchored Root of Trust, NIST-standardized post-quantum cryptography protocols like CRYSTALS-Kyber and Dilithium, secure ASIC architectures for cryogenic control electronics, and integrated identity management from silicon to cloud orchestration.
2. Quobly Stake and EeroQ Investment
The company shifted from pursuing a full acquisition of French quantum startup Quobly to acquiring a minority stake through its Series A financing round while deepening its strategic investment in EeroQ, a US-based developer of quantum computing chips.
3. Q1 2026 Revenue Outlook
SEALSQ projects Q1 2026 revenue growth of 50%–100% year over year, driven by anticipated demand for its post-quantum semiconductors and end-to-end cybersecurity services as quantum computing infrastructure deployments accelerate.
4. Geneva Headquarters Relocation
SEALSQ will relocate its Geneva headquarters to the Pont-Rouge business district in August 2026, leveraging low-carbon infrastructure and enhanced connectivity to support its expanding global semiconductor and cybersecurity operations.
