“We looked for an internet provider that had a stable wired connection that could maintain a good quality upload speed as well as a download speed, so that when saving and uploading X-rays and CT scans, there would be no lag to dentists and patients in the surgeries. So many clinics are going from paper based to cloud based systems without the infrastructure to support it. I highly recommend SIRO broadband for other healthcare providers. It was very easy to deal with and there was great communication.”
“We are a family-run store with a love of great food and great service and behind the scenes, tech is a huge part of making that happen. With Fastcom’s SIRO LightPulse connection, everything runs faster. Uploading product photos is instant, our phone service is crystal clear, and customers get quicker service at the tills. It’s really taken the pressure off day-to-day.”
“One of the huge advantages we found with using SIRO is the flexibility. We are using VYPE and getting rid of the PBXs. We are now using cloud-based comms and IM like Zoom and Teams, and using cloud, remote, and virtual technology, so SIRO is the way to go. It supports all that technology and opens us up.
What may seem like an investment at the start, will see a return very quickly. For the businesses I am providing support for, that return came instantly. I was thinking “Wow, where would we be without it. Why didn’t we have it two years ago?”.
Killarney is a tourist town; you can have 20,000 people here at any Bank Holiday weekend. We need SIRO broadband. Everyone is using social media and uploading content. If you are not in that bubble, you are going to be very disconnected. It is a huge plus to be able to engage with our audiences in that sense too. It needs to be something people can adapt to.”
“The personalised service and responsiveness we’ve received from Viatel have been outstanding. Our dedicated Account Manager, Damien Peelo, has been instrumental in ensuring our needs are met. We’ve had the opportunity to visit Viatel’s Blanchardstown HQ, meeting the entire project team, and we benefit from weekly touchpoint calls with our Project Manager in the Service Delivery Team. This level of visibility and transparency has been transformative. With access to Viatel’s 24/7/365 Network Operations Centre and enterprise-grade SLAs, we feel consistently supported and valued at every stage of the partnership.”
Damien McCann, Chief Commercial Officer at Viatel – “At Viatel, we are dedicated to partnering with industry leaders like SIRO to provide our customers with the best possible solutions. We are experts in enterprise connectivity, and we understand that reliable, high-speed connectivity is the bedrock for all our other digital services.”
“SIRO’s symmetric fibre enterprise connections are ideal for building our advanced SD-WAN networks, providing the necessary bandwidth for Microsoft applications, ensuring robust cybersecurity, facilitating seamless access to cloud workloads, and supporting other critical managed services. This connectivity is vital to support the best possible customer experience for businesses like INTERSPORT Elverys.”
“At St. Anne’s Church Shandon Bells & Tower, we welcome thousands of visitors each year, while also serving as an active Anglican parish. Reliable broadband is vital for running our booking and payment systems smoothly, so making the switch to LightPulse, powered by SIRO, has been a big success for us.
“It is our first time using a fibre connection, and the difference has been remarkable. We had experienced slow and unreliable connectivity in the past and it often caused frustration when managing bookings or payments. Choosing LightPulse through Digiweb transformed that experience. The installation process, which we had been a little apprehensive about, was handled quickly, efficiently, and with excellent communication throughout.
“Since upgrading, our payment and booking systems run seamlessly, and we no longer worry about connectivity holding us back. For any business struggling with unreliable broadband or needing to support more devices, we would highly recommend LightPulse”.
SIRO is rolling out a fibre broadband network to help our customers and communities Do Life Different.

SIRO, a leading Irish fibre to the home (FTTH) broadband operator, has won the European Fibre Broadband Operator of the Year 2025.
The Award, which is awarded by the Fibre to the Home Council of Europe, recognises companies who have made a significant contribution to the development of full fibre broadband connectivity across Europe.
SIRO’s key innovation is that it is a 100% fibre-optic internet connection all the way to the building (fibre-to-the-building), making it a vast improvement on any other broadband infrastructure currently available in Ireland, with no copper connection at any point in the network. SIRO is Fibre-to-the-building which means you’ll have incredible speed and reliability instantly.
When you purchase SIRO from a broadband provider, an engineer will visit your home at a time agreed by you to complete the fibre first installation. SIRO will be brought into your home either overhead or underground and into the ESB meter box. An external connector box which houses the SIRO fibre will be positioned close to the ESB meter box.
The engineer will agree with you where to install our internal connector box. Some minor drilling is involved and some cabling depending on where you would like your modem. The engineer will ensure and prove that your home is receiving the fibre first speed based on the package purchased.
For SME and Enterprise customers, an engineer will work with the business to determine the entry point. Where applicable the existing communications space will be utilised.
SIRO is a joint venture company between the ESB and Vodafone. We are building a 100% fibre-to-the-premise broadband network using the existing ESB infrastructure.

ESB was a pioneer in electrifying Ireland and have unparalleled knowledge of large-scale engineering projects. Vodafone is Ireland’s leading mobile telecoms operator, with over a million customers and world-leading expertise in the transmission of data. These two companies enable SIRO to build a regional 100% fibre-to-the-building network, the first of its kind in Ireland. In 2021, we have received further investment of €620m into the expansion of our network to 770k homes and businesses across 154 towns.
