Vancouver, British Columbia--(Newsfile Corp. - November 5, 2025) - Plurilock Security Inc. (TSXV: PLUR) (OTCQB: PLCKF) ("Plurilock" or the "Company"), a global cybersecurity systems integrator, announces that it has been awarded follow-on contracts totaling US$868,600 with an existing NASDAQ-listed semiconductor client to provide Security Operations Center ("SOC") services under its Critical Services business unit.

The contracts include an eight-month US$676,000 direct services engagement and a six-month US$192,600 resell services expansion, further solidifying Plurilock's role as a trusted partner in safeguarding the client's complex, global infrastructure.

Under these agreements, Plurilock's Critical Services ("PLCS") and Security Operations ("SecOps") teams will design, implement, and operate a 24/7 SOC delivering continuous threat detection, proactive defense, and rapid incident response. The engagement expands Plurilock's presence in the semiconductor and high-technology manufacturing sectors, which face heightened cyber risks due to their strategic role in national infrastructure, defense supply chains, and innovation ecosystems.

"Our Critical Services business continues to deliver for enterprise clients that demand trusted, always-on cybersecurity operations," said Ian L. Paterson, CEO of Plurilock. "This award highlights the strong performance of our expanding SecOps practice and the deep confidence that large, publicly traded organizations place in Plurilock to protect their most sensitive assets."

Powering Detection and Response Through Partnership

Plurilock's collaboration with a leading cybersecurity technology partner played a key role in enabling these contracts. By integrating advanced endpoint detection and response ("EDR") capabilities into the Company's service delivery model, Plurilock delivers faster, more accurate threat detection and automated containment across client environments.

"Our integrated technology partnerships amplify the value we deliver," continued Ian L. Paterson, CEO of Plurilock. "This engagement exemplifies how we build long-term client relationships, earning trust through performance and expanding into larger, re-occurring service opportunities over time."

As with prior Critical Services contracts, Plurilock expects fulfillment costs and gross margin profiles to remain consistent with historical performance as disclosed in its latest MD&A. Further details with respect to the terms of the contract are subject to confidentiality and non-disclosure.
