PLDT, Inc.

PLDT, Inc. runs the backbone of the Philippines' digital infrastructure. As the country's largest and most diversified fully integrated telecommunications company, its attack surface is enormous: fixed-line networks, the Smart Communications mobile grid, fiber deployments under PLDT Home, and the enterprise ICT stack delivered through PLDT Enterprise. The threat model here is national-scale - protecting connectivity layers that millions depend on daily, from residential broadband to business-critical services. Founded in 1928, PLDT has spent nearly a century accumulating the kind of legacy infrastructure that keeps security engineers up at night. The company's scope spans telecommunications, digital services, fiber internet, mobile connectivity, and ICT services. PLDT Enterprise alone delivers enterprise-grade solutions to businesses across the Philippines, while Smart Communications handles mobile connectivity and digital solutions at consumer scale. That's a lot of surface area to defend, monitor, and harden. The technical domains map directly to core cybersecurity challenges: securing converged fixed and wireless networks, protecting digital service platforms, defending enterprise client infrastructure, and maintaining the integrity of fiber and mobile connectivity layers that serve as critical national infrastructure. PLDT operates entirely within the Philippines, making it a concentrated, high-stakes environment where telecom security isn't abstract - it's the difference between a connected nation and a dark one.
