Plurilock Announces New Critical Services Customers and Account Expansions

• Signed three new PLCS customers
• Broadened scope with two existing PLCS clients, reinforcing trusted relationships
• Proven model of transitioning initial projects into long-term reoccurring, high-margin partnerships

Vancouver, British Columbia--(Newsfile Corp. - September 18, 2025) - Plurilock Security Inc. (TSXV: PLUR) (OTCQB: PLCKF) ("Plurilock" or the "Company"), a global cybersecurity services provider, announces that it added three new clients to its Plurilock Critical Services ("PLCS") portfolio over the past 30 days and also expanded two existing customer relationships, reflecting continued and organic growth as customers engage Plurilock as a trusted advisor across both commercial and enterprise markets.

The new client wins represent initial Critical Services engagements across incident response, security architecture, and data protection. Consistent with Plurilock's proven land-and-expand model, these initial 5-figure engagements are designed to establish trust, demonstrate value, and serve as the foundation for multi-year, recurring project revenue. Many of the Company's largest and most profitable contracts began this way as smaller initial engagements.

In addition, Plurilock expanded work with two existing PLCS clients, broadening the scope of services delivered and reinforcing its position as a trusted partner. These expansions highlight Plurilock's ability to grow accounts over time by embedding deeply in client environments and addressing increasingly complex security requirements.

"We are seeing strong momentum in our Critical Services offerings with three new customer agreements in a single month," said Ian L. Paterson, CEO of Plurilock. "We also had two account expansions, demonstrating our ability to convert initial projects into deeper, long-term partnerships and the reoccurring nature of these projects. In the last 30 days alone, we have also added over $10 million in new Critical Services pipeline, with many of these opportunities starting as seven-figure initial bids. Thanks to our growing reputation, past performance, and key partnerships, Plurilock is now being invited into larger opportunities from the outset, including NATO-aligned defense programs."

Together with Plurilock's recently announced CloudCodes divestiture and the broader program of corporate streamlining and operational optimization, these wins and the expanding pipeline further strengthen the Company's path toward profitability.
