"Following the early adoption and onboarding of our first subscription customer, an Ontario border police agency, we are pleased to announce today the commercial release of DEFSEC LightningTM along with a compelling scaled pricing model aligned with public safety mission requirements," said Sean Homuth, DEFSEC President and CEO. "The system is designed for simplicity and easy on-boarding, with virtually zero time to value and tools specifically for first responders".

DEFSEC LightningTM is a turnkey, cloud-hosted TAK-based SaaS (Software as a Service) platform that gives every officer, medic and firefighter a real-time common operating picture on the device in their pocket, vehicle or command centers.

The platform builds on the widely adopted Team Awareness Kit ecosystem used by the U.S. and Canadian military and key allied nations, while removing the deployment and operational complexity that has historically limited adoption by civilian agencies. The system builds on DEFSEC's track record of TAK development for North American militaries and is designed to eliminate the need for dedicated hardware, software installation, or internal IT management, enabling rapid deployment and operational readiness.

Core Capabilities

DEFSEC LightningTM provides an integrated set of mission-critical capabilities, including:

• Real-time location tracking (Blue Force Tracking): Continuous geo-location of responders and assets on a shared operational map.
• Secure multimedia communications: encrypted text, voice, photo, and video, integrated into a unified interface — replacing voice-only radio relay with a full multimedia common operating picture.
• Encrypted data and imagery from any source — including video from drones, surveillance cameras, body-worn cameras, fixed sensors, and sniper scopes — fused into the same map that every responder sees.
• Interoperability: seamless coordination both within and across agencies during joint operations.
• Operationally optimized interface: role-based user experience for front-line responders with minimal training requirements.
• Scalable cloud infrastructure with a battery-aware wake-up function — configured so a 50-officer detachment and a 30,000-officer metro service can run on the same platform, and an officer's phone isn't dead by hour three of a shift.

Mission-Specific Toolkits

In addition to its core platform, DEFSEC LightningTM includes specialized apps tailored to public safety workflows, including:

• GSAR (Ground Search And Rescue): a unique toolkit designed to vastly improve the efficiency and effectiveness of GSAR operations.
• TAK-enabled Sniper and Surveillance (T-SAS): live spotter-scope video distribution from observation systems across the command chain over any available communications system.
• Geofenced incident call-out: Automated notification and activation of responders within defined geographic areas. Commanders draw an area on the map and LightningTM instantly messages every responder inside it, alerting them to the incident even if they aren't logged in at the time, while also protecting data sovereignty and privacy. Closes the gap between an incident breaking and the right responders having the right information immediately.

Technical Architecture and Deployment

More information on the architecture, design and security features of DEFSEC LightningTM is available on the Company's website at www.defsectec.com .

Pricing and Market Opportunity

DEFSEC LightningTM is offered on a subscription basis ranging from approximately CAD $15 to $50 per end-user device per month, depending on configuration, scale and service level response time.

The Company estimates the addressable market as follows:

• Sworn police (U.S. & Canada): ~779,000 officers, representing an estimated CAD $140 million to $467 million annual recurring revenue opportunity (TAM.1)
• Total first responders (North America): ~2.5M+ uniformed personnel including fire and EMS/paramedic services, representing an estimated CAD $450 million to $1.5 Billion+ annual recurring opportunity (TAM2).

Go-to-Market Advantage

DEFSEC enters the market with an established footprint in the public safety sector through its ARWEN® less-lethal product line, which is currently deployed across Canadian and U.S. law enforcement and corrections agencies. "DEFSEC LightningTM extends our existing relationships by adding a critical digital capability alongside our trusted field equipment", said Sean Homuth.

Expansion into Defence Applications

In addition to public safety markets, the Company believes DEFSEC LightningTM has applicability across defence use cases, including the Canadian Armed Forces (CAF) , Reserve units, and joint Arctic operations.

The platform is designed to operate in low-bandwidth environments and support interoperability between military, law enforcement, disaster relief, and search-and-rescue organizations. This aligns with Canada's ongoing modernization priorities in the North, and could provide a leap-ahead in coordinated interoperability across agencies in joint Arctic operations.
