VANCOUVER, BC, Sept. 17, 2026 /PRNewswire/ — Equity Insider News Commentary – A satellite launched this year may still be flying in the 2040s. The cryptography protecting its command links, its downlinks and its ground segment was, in most cases, chosen years before launch and cannot be swapped out with a service call. That mismatch between hardware lifecycles and cryptographic lifecycles is why post-quantum security has moved from a research topic to a procurement question inside space agencies, and why the work is starting now rather than when a cryptographically relevant quantum computer actually exists. Encrypted traffic captured today can be stored and decrypted later, which means the clock on long-lived space infrastructure is already running. Active Companies from around the markets with current developments this week include: Quantum Secure Encryption Corp. (CSE: QSE) (OTCQB: QSEGF) (FSE: VN80), Arqit Quantum Inc. (NASDAQ: ARQQ), IonQ, Inc. (NYSE: IONQ), Rocket Lab Corporation (NASDAQ: RKLB), and Planet Labs PBC (NYSE: PL).

The security problem in space is not one system, it is the number of seams. A modern space mission connects satellites, ground stations, terrestrial networks, cloud environments and downstream data infrastructure, and every junction between them is a place where cryptography has to hold. Each of those components is procured separately, refreshed on a different schedule and often operated by a different organisation. Replacing the cryptography across that chain is not a patch, it is a programme.

That is why the sequencing has become the whole discipline. Before an organisation can migrate, it has to know what it is running: which algorithms, in which systems, with which dependencies, and which of them are embedded in hardware that cannot be updated. Cryptographic discovery and inventory has become the first billable step in almost every serious post-quantum programme, ahead of any decision about what to replace it with.

Europe is moving on this in public. The demonstration side of the market has already shown the approach can work on live infrastructure rather than in a laboratory, and agencies responsible for long-lived orbital assets are now in the position of writing requirements. For companies with cryptographic discovery, migration planning and quantum-resilient security capability, the practical question is whether they are in the room while those requirements are being drafted, or reading them afterwards.

QSE Advances European Space Security Strategy Through European Space Agency Engagement

• Selected as one of nine Canadian quantum companies participating in the Government of Canada-supported Canadian Quantum Enabling Technologies Applied to Space Technology R&D Partnering Delegation to the Netherlands.
• Joined the Canadian delegation at the European Space Agency, engaging with ESA Earth Observation project programs ahead of European Space Agency Industry Space Days.
• Direct exposure to emerging security requirements and potential applications for post-quantum cybersecurity across future satellite and space infrastructure.
• Further engagements at the Canadian Embassy in The Hague and in Delft with organizations including QDNL, House of Quantum and TNO.
• Framed as part of a broader international growth strategy targeting technology partners, research organizations and potential customers in markets where post-quantum requirements are expected to become increasingly important.

Quantum Secure Encryption Corp. (CSE: QSE) (OTCQB: QSEGF) (FSE: VN80), a post-quantum cybersecurity company focused on quantum-resilient data protection, identity security, secure storage and cryptographic migration readiness, provided an update on its participation in the Government of Canada-supported Canadian Quantum Enabling Technologies Applied to Space Technology R&D Partnering Delegation to the Netherlands, including engagement with the European Space Agency.

QSE was selected as one of nine Canadian quantum companies participating in the delegation, which connects Canadian innovators with Dutch organizations to explore research and development collaboration, technology validation, commercialization opportunities and potential partnerships across the quantum and space sectors. As part of the mission, QSE joined the Canadian delegation at ESA, where participants engaged with ESA Earth Observation project programs ahead of the European Space Agency Industry Space Days.

The Company’s stated position is that space systems increasingly connect satellites, ground stations, terrestrial networks, cloud environments and other data infrastructure, creating more pathways that must remain secure over long operating lifecycles, and that its cryptographic discovery, migration planning and quantum-resilient security capabilities may be relevant as space organizations prepare for post-quantum requirements. That is a carefully bounded claim and worth reading as written. It describes relevance and exposure to requirements rather than any contract, award, procurement or commercial arrangement, and the Company has announced none in connection with the delegation.

“This delegation gives QSE direct access to organizations helping shape the next generation of European space and quantum infrastructure,” said Ted Carefoot, Chief Executive Officer of QSE. “Our objective is to engage early, understand where security requirements are heading and position QSE where our technology can address a clear operational need.”

QSE also participated in engagements at the Canadian Embassy in The Hague and in Delft with organizations including QDNL, House of Quantum and TNO, exploring potential collaboration in quantum communications, secure technologies, satellite applications and related emerging technologies. The Company views the delegation as part of a broader international growth strategy focused on developing relationships with technology partners, research organizations and potential customers in markets where post-quantum security requirements are expected to become increasingly important.

What a trade delegation does and does not do is worth stating plainly, because the distinction matters to how this should be read. It puts a small company in front of buyers and standards bodies at the point where requirements are still being written, which is cheaper and more useful than responding to a tender later. It does not produce revenue, and there is no assurance that any relationship, collaboration or commercial arrangement will result from it. QSE describes itself as specializing in post-quantum data security, encryption and secure data infrastructure, built around quantum-delivered entropy and zero-knowledge architecture, serving commercial, enterprise and public-sector environments requiring long-term data confidentiality.

In other industry developments and happenings in the market this week include:

Arqit Quantum Inc. (NASDAQ: ARQQ) announced on September 1, 2026, together with Qatar satellite operator Es’hailSat and systems integrator Advanced International Electronic Equipment Company, the successful demonstration of quantum-safe security across operational satellite communications infrastructure. The trial ran at Es’hailSat’s Tier-4 certified Teleport facility in Doha using the live Es’hail-1 satellite at the 25.5 and 26 degrees East orbital hotspot.

The detail that makes it relevant is the absence of new hardware. The companies reported that quantum-safe cryptographic protection was introduced across existing satellite-connected networks with no adverse effect on existing systems, services or operational performance. Chief Executive Andy Leaver described it as proving a practical path to quantum-safe resilience without requiring operators to rebuild existing infrastructure. Arqit’s products span Encryption Intelligence, which detects cryptographic exposure and maps dependencies, and NetworkSecure, which protects data in transit. It is a materially larger and differently financed company and is referenced as sector context rather than as a comparable.

IonQ, Inc. (NYSE: IONQ) raised its full year 2026 revenue outlook to between $450 million and $460 million in September 2026, incorporating contributions following its SkyWater consolidation. At IEEE Quantum Week 2026 the company presented nine peer-reviewed papers, four of which received Best Paper Awards, covering hybrid high-performance computing and quantum artificial intelligence workflows.

IonQ sits on the other side of this market and is the reason the security side exists. Post-quantum cryptography is a response to the machines that companies like IonQ are building, and the commercial scale now attached to that effort is what has moved migration timelines from theoretical to budgeted. A security vendor and a quantum computing manufacturer are not competitors, and neither is a comparable of the other.

Rocket Lab Corporation (NASDAQ: RKLB) was awarded a $266 million multi-launch contract with the U.S. Space Force in July 2026, its largest launch contract to date, covering 12 suborbital launches with up to six additional launches under the Space Systems Command Rocket Systems Launch Program, primarily from a new location at the Pacific Spaceport Complex in Kodiak, Alaska. In August it was selected by Viasat to build a GEO satellite bus for the Protected Tactical SATCOM-Global program and was onboarded to the Space Force’s Space Data Network Consortium.

Rocket Lab is included because it illustrates the scale and the lifecycle of the assets this security conversation is about. Anti-jam national security satellites and protected tactical communications programmes are precisely the long-lived, high-value systems where cryptographic agility has to be designed in rather than retrofitted. It is a launch and space systems company, not a security company, and its results are not indicative of any security vendor’s prospects.

Planet Labs PBC (NYSE: PL) operates the world’s largest commercial fleet of Earth observation satellites, the same category of programme QSE engaged with at ESA. The company reported record revenue in its most recent quarter, has been expanding into sovereign and national-level data programmes including a national satellite data programme announced with the Government of Rwanda in August 2026, and has been adding European defense work.

Earth observation is where the security question gets sharpest, because the data has national security value, the customers are increasingly governments, and the imagery archive has a long useful life. An archive that matters in 2040 has to be protected by cryptography that still holds in 2040. Planet Labs is a capital-intensive constellation operator at a completely different stage and scale and is named solely as sector context.
