STMicroelectronics Launches Quantum-Ready Mobile Security Chip

Quantum XChange announced it has joined the Cisco Networking App Marketplace as a Cisco Technology Partner, listing its Phio TX-EM containerized post-quantum cryptography key management application in the Marketplace catalog. The listing makes Phio TX-EM the first FIPS-validated post-quantum cryptography solution available in the Marketplace, giving Cisco customers, sellers, and channel partners worldwide a direct path to quantum-safe networking on their current Cisco infrastructure. Phio TX-EM is a virtualized container application that runs natively on Cisco SKIP-enabled devices supporting third-party containers, including the Cisco Catalyst 8000 Series products and Nexus switches, and it is FIPS 140-3 Level 2 and FIPS 203 validated. Tom Butta, Chief Commercial and Marketing Officer at Quantum XChange, said federal mandates and industry timelines are landing ahead of most hardware refresh cycles, and that Phio TX-EM delivers quantum-safe keys through Cisco's SKIP API with no added hardware, no downtime, and no additional performance impact. The application is listed now in the Cisco Networking App Marketplace.

WISeQey Corp., formerly WISeKey International Holding AG, began trading on Nasdaq and SIX today under the new symbol WQEY following its redomiciliation from Switzerland to the British Virgin Islands. The company also congratulated its subsidiary WISeSat.Space Holdings Corp., now listed on Nasdaq as SAIQ, which closed a $10 million private investment in public equity on October 1, 2026, from SEALSQ Corp, a fellow WISeQey subsidiary. The purchase price was $10.79 per share, equal to the redemption price from the business combination, and the subscription agreement includes a price-protection mechanism that may trigger additional share issuance to SEALSQ if the volume-weighted average price over the 10 consecutive trading days ending on the 60th calendar day after closing falls below the purchase price, subject to a $5.00 floor. The PIPE capital is intended to fund WISeSat.Space's satellite infrastructure expansion and the integration of post-quantum cryptography into its satellites, ground and user-segment architectures, while SEALSQ plans to use WISeSat.Space satellite capacity to deliver quantum and post-quantum services. Carlos Moreira serves as CEO of WISeQey, WISeSat.Space and SEALSQ, making the PIPE investment and planned collaboration related party transactions.

WISeSat.Space Holdings Corp. has completed its previously announced business combination with Columbus Acquisition Corp. and begun trading on the Nasdaq Capital Market under the ticker symbol "SAIQ" as of October 2, 2026. CAC shareholders approved the business combination at an extraordinary general meeting on September 30, 2026, and the transaction closed on October 1, 2026. The deal establishes WISeSat.Space, a space technology company and subsidiary of WISeQey Corp., as a separately listed public company focused on post-quantum-secure satellite communications and Internet of Things connectivity. WISeSat.Space has deployed satellites into orbit since 2024 and aims to integrate hardware-based security, device authentication and post-quantum protection into its satellite communications architecture. Carlos Moreira, Chief Executive Officer of SEALSQ, WISeQey and WISeSat.Space, called the Nasdaq listing an extraordinary milestone and said trust and post-quantum security must be built into satellite infrastructure from the outset. Maxim Group LLC served as WISeSat.Space's financial advisor, with Ellenoff Grossman & Schole LLP and Harney Westwood & Riegels (BVI) LP as legal counsel, while Loeb & Loeb LLP and Ogier represented CAC.

MarketsandMarkets projects the global post-quantum cryptography market will grow from $0.42 billion in 2025 to $2.84 billion by 2030, a compound annual growth rate of 46.2%. The forecast is a third-party projection, not a guarantee, and timelines for quantum capability remain debated, though large infrastructure vendors have started publishing migration dates and quantum hardware companies are reporting rapid revenue growth off small bases. Among this week's developments, Vancouver-based Quantum Secure Encryption Corp. appointed Joseph Hall as Chief Intelligence Officer, adding more than 20 years of frontline cybersecurity and threat intelligence experience, with prior roles including Director of Threat Intel R&D at Infoblox and Principal Security Consultant at Fortinet; he will work with Chief Technology Officer Michael Massing, who previously led Dell SonicWall's Unified Threat Management business unit. QSE also announced grants of 350,000 stock options and 350,000 restricted share units to employees. Separately, Cloudflare announced plans to become a public certificate authority issuing post-quantum Merkle Tree Certificates with production issuance scheduled for the first quarter of 2027, IonQ reported second quarter 2026 revenue of $80.1 million, up 287% year over year, and raised its full-year 2026 revenue outlook to $450 million to $460 million, Akamai announced an $11.6 billion multi-year agreement with Anthropic to supply distributed AI infrastructure and cloud computing services over seven years, and Okta reported second quarter fiscal 2027 total revenue of $805 million, up 11%, guiding to fiscal 2027 revenue of $3.216 billion to $3.226 billion.
