Vancouver, British Columbia--(Newsfile Corp. - March 12, 2026) - QSE - Quantum Secure Encryption Corp. (CSE: QSE) (OTCQB: QSEGF) (FSE: VN80) announces an update regarding its participation in several major international cybersecurity and post-quantum security conferences scheduled throughout 2026, as the Company continues to expand engagement with global industry, government, and enterprise stakeholders preparing for the transition to post-quantum cryptographic standards.

The update follows the Company's January 21, 2026 announcement outlining its initial 2026 conference planning and growing number of invitations to participate in global cybersecurity and post-quantum cryptography forums.

Since that announcement, QSE has confirmed participation in several prominent international cybersecurity events across Europe, Asia, the Middle East, and North America, including:

• Quantum Security Defence World Symposium (Paris, FRA) — industry forums focused on post-quantum cryptography and quantum-era cybersecurity strategy

• GITEX Quantum Expo Asia (Singapore) — technology and investor conferences focused on emerging cybersecurity infrastructure

• Cyber UK 2026 (Glasgow, SCO) — one of the United Kingdom's leading government-supported cybersecurity conferences

• GISEC Global (Dubai) — participation as part of a Canadian cybersecurity delegation supporting international technology collaboration

• Gartner Security & Risk Management Summit (Washington, D.C.) — a major gathering of enterprise cybersecurity leaders and technology decision-makers

These events bring together cybersecurity leaders, government agencies, enterprise security teams, and technology providers to address emerging challenges associated with the transition toward post-quantum cryptographic standards and the long-term protection of sensitive data.

QSE's participation in these events reflects growing global attention on enterprise readiness for post-quantum cryptography and the need for structured migration planning as organizations begin evaluating long-term cryptographic risk exposure.

"Our industry is entering a period where post-quantum migration planning is becoming a practical priority for governments and enterprises," said Ted Carefoot, CEO of QSE. "Participating in these global forums allows us to contribute to the broader industry dialogue around cryptographic transition while engaging directly with organizations evaluating how to prepare their infrastructure for the post-quantum era."

QSE's platform includes its Quantum Preparedness Assessment (QPA) system designed to assist organizations in identifying cryptographic dependencies and planning long-term migration strategies, along with its qREK quantum-resilient key SDK, QAuth identity and authentication platform, and decentralized encrypted storage architecture.

The Company expects collaboration across industry, government, and technology communities to play a critical role in supporting enterprise readiness as post-quantum migration initiatives accelerate globally.
