Eir

Eir provides fixed‑line voice, broadband internet, mobile communications and television services to residential and business customers throughout Ireland. The company operates a national network that includes copper, fibre‑to‑the‑home and cable infrastructure, enabling it to deliver a range of connectivity options. Its product portfolio encompasses traditional telephone lines, high‑speed broadband packages, mobile voice and data plans, and bundled TV offerings. Eir also supplies wholesale services to other telecommunications operators seeking access to its network infrastructure.

As Ireland’s incumbent telecommunications operator, Eir holds a prominent position in the market and is subject to regulation by the Commission for Communications Regulation (ComReg). The firm’s long history, dating back to the former state‑owned Telecom Éireann, has given it extensive expertise in managing nationwide communications assets. Notable competencies include the rollout of fibre‑based broadband and the maintenance of a large customer‑premises equipment base, which has occasionally required rapid security responses. In December 2016 the company warned broadband customers of a virus affecting certain Zyxel modems, advising password resets and issuing direct notifications. In April 2014 Eir experienced unauthorized access to its email service perimeter, leading to a temporary shutdown, notification to data‑protection authorities and a prompt restoration of webmail access. These incidents illustrate the operator’s focus on safeguarding its services while maintaining continuity for its users.
