Cisco Systems has added Quantum XChange's post quantum cryptography solution to the Cisco Networking App Marketplace, offering quantum safe key management that plugs directly into Cisco networking equipment. The company said this is the first FIPS validated post quantum cryptography product available through its marketplace. The integration lines up with Cisco's push to embed more security functions inside the network itself and with its focus on secure AI infrastructure, including projects such as the Bell Canada sovereign AI platform for regulated workloads. The key proof point going forward is customer adoption of Cisco's quantum safe and AI security offerings, particularly in government and regulated sectors, with upcoming quarterly reports and customer case studies as the places to watch for references to quantum resistant deployments on existing Cisco hardware and to new deals tied to sovereign or high sensitivity AI projects.

WISeSat.Space Holdings Corp. announced that its management team will ring the Nasdaq Opening Bell on Friday, October 9, 2026, celebrating the listing of its ordinary shares on Nasdaq and outlining its strategy to develop trusted, quantum-resilient space communications. Following the ceremony at 151 West 43rd Street, the company will host a Quantum Space Security Roundtable from 10:00 a.m. to 4:00 p.m. ET, bringing together experts in space, quantum technology and cybersecurity to discuss protecting satellite communications against emerging quantum computing threats. The roundtable will be held in two sessions moderated by Founder and CEO Carlos Moreira: the first, "Space Security and Sovereignty," will feature Jessica Rosenworcel, Executive Director of the MIT Media Lab and former Chair of the US Federal Communications Commission; Cristina Dolan, Non-Executive Director of SEALSQ; Liz Hanson, Managing Director of Technology Investment Banking at KeyBanc Capital Markets; and Mark Minevich, Strategic Partner at Mayfield and President of Going Global Ventures. The second session, "Building the Secure Space Stack," will feature Julián Fernández, CEO and Co-founder of FOSSA Systems; Nick Farina, Co-founder and CEO of EeroQ; and, from WISeSat.Space, Philip Hamelink, Interim Head; Gwenael Rouy-Poirier, Chief Financial Officer; and Alex Moreira, Satellite Sales Engineer. The event will highlight WISeSat.Space's role in supporting the planned Quantum Spatial Orbital Cloud roadmap, a SEALSQ-owned quantum and post-quantum service roadmap expected to leverage WISeSat satellite infrastructure as part of its future orbital layer, with the company intending to expand that orbital infrastructure through planned next-generation satellite missions.

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.
