Ciena and Colt complete first quantum-safe 800GbE transatlantic trial

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.

DigiCert announced support for the NVIDIA Open Agent Safety Platform, pairing its DigiCert AI Trust Manager with NVIDIA OpenShell to give enterprises verifiable identity and authority for autonomous AI agents. OpenShell, the open secure runtime at the center of the platform, permits nothing by default, enforces policy outside the agent's process, and records every allow-or-deny decision, while DigiCert AI Trust Manager discovers and manages agents, establishes each agent's identity and ownership, defines what it is authorized to do, and revokes that authority with a kill switch when trust changes. Each agent receives a DigiCert AI Passport, a portable cryptographically signed credential tied to an accountable owner, plus policy-based visas defining which systems, data, and actions it may access and for how long; because the passport and permissions travel with the agent, other systems and organizations can verify them without relying on the same identity provider. The support is built around four areas: identity that policy can act on, verification before execution through signed agents, models, and MCP servers tied to an AI Bill of Materials, auditable evidence binding trusted identity to OpenShell's allow-and-deny records, and trust across company boundaries using the same PKI model that secures the internet. DigiCert CEO Amit Sinha said NVIDIA creates the boundary around the agent while DigiCert establishes who the agent is and what authority it has, and that PKI, which solved cross-boundary trust for the internet at scale, has an important role in establishing trust for autonomous agents. Support begins with NVIDIA OpenShell, with additional capabilities planned as the two companies continue to advance enterprise AI trust and agent security.
