LG Uplus announced Tuesday that it has acquired Pago Networks, a South Korean specialist in managed detection and response (MDR) services, marking the carrier's first merger deal as part of a broader strategy to establish security as a core growth business.

MDR providers continuously monitor client systems and take direct action against threats as they emerge, rather than simply issuing alerts. The model has gained traction globally as organizations face persistent cybersecurity talent shortages and escalating volumes of security alerts that in-house teams struggle to triage. The financial terms of the transaction were not disclosed. The companies declined to reveal the acquisition price, the size of the stake acquired, or whether Pago Networks will become a consolidated subsidiary, citing confidentiality agreements.

LG Uplus ranks as South Korea's third-largest mobile carrier by handset subscribers, trailing SK Telecom and KT. Under CEO Hong Beom-sik, who assumed leadership in late 2024, the company has divested noncore ventures and redirected investment toward artificial intelligence, data centers, and security — domains where telecom operators increasingly seek to build enterprise revenue beyond mature connectivity markets.

The acquisition is intended to serve a dual purpose. LG Uplus plans to integrate Pago's threat detection and response teams into its own internal defense operations while simultaneously leveraging the same capabilities to serve corporate clients. The carrier intends to pair MDR services with its existing security monitoring portfolio, which includes its quantum-resistant authentication service AlphaKey and its cloud-based U+SASE offering.

The internal security rationale carries particular significance given the company's recent history. In 2023, the Personal Information Protection Commission fined LG Uplus 6.8 billion won ($4.8 million) following a data breach that exposed the personal information of approximately 297,000 customers.

Pressure across the Korean telecom sector has only intensified since then. In 2025, SK Telecom disclosed a breach affecting subscriber records, resulting in a fine of roughly 134 billion won. In response, SK Telecom pledged 700 billion won in security investments over a five-year period — a commitment that effectively establishes a spending benchmark for competitors in a market where subscriber trust has become tightly coupled with demonstrable cybersecurity investment.

Owning an MDR operator rather than outsourcing monitoring enables a carrier to retain threat intelligence in-house and feed it directly into proprietary detection systems.

Founded in 2017, Pago Networks operates on a self-developed platform called DeepACT. According to the company, its client base spans the finance, manufacturing, and IT sectors, and it has expanded into seven Southeast Asian markets, including Malaysia and the Philippines. That regional footprint aligns with a broader pattern of Korean technology firms commercializing security and enterprise IT capabilities across Southeast Asia, where digital infrastructure build-outs and strengthened data-protection regulations have expanded demand for managed cybersecurity services.

The acquisition adds concrete capability to the "Secure AI" strategy that LG Uplus outlined ahead of MWC 2026.

"This acquisition is a decision to offer corporate customers more complete security services while raising our own response capabilities a notch," said Kwon Yong-hyun, head of the enterprise business unit at LG Uplus. He added that the company aims to establish itself as a security partner that clients can trust.
