Ultra-Fast Business Broadband You Can Rely On
Slow internet doesn’t just frustrate your team; it costs you money. We provide enterprise-grade connectivity built for the modern, cloud-first workplace. From essential FTTP (Fibre to the Premises) to dedicated Leased Lines, we guarantee the bandwidth, low latency, and uptime your daily operations demand.
As Dublin solidifies its position as Europe’s premier tech and financial hub, legacy copper connections simply can’t keep pace. We help Irish businesses transition to full-fibre infrastructure, ensuring you have the high-speed, uncontended access needed to compete without interruption.
- Dedicated Leased Lines: Symmetrical, uncontended speeds up to 10Gbps - your bandwidth is exclusively yours.
- Rock-Solid Reliability: Backed by robust SLAs (Service Level Agreements) and automatic 4G/5G failover options so you never go offline.
- Future-Proof FTTP: Say goodbye to the old network. Upgrade to pure fibre for seamless video calling, large file transfers, and cloud access.

We act as your fully outsourced IT department, providing proactive monitoring to stop tech headaches before they impact your team. From everyday helpdesk queries to complex Microsoft 365 migrations, we manage the technology so you can manage your business.
While we fix 90% of issues remotely, having a local partner matters. Our engineers provide rapid, boots-on-the-ground support across Glasgow and the Central Belt, as well as Ireland and Northern Ireland – ensuring you’re never left waiting when a critical hardware failure occurs that requires a site visit.

Big Business Cybersecurity for Small Business Prices
Cyber attacks are no longer just an enterprise problem; SMEs are now the primary target for ransomware and phishing. We deploy advanced endpoint protection, strict email filtering, and automated backups to build an impenetrable wall around your sensitive data, protecting your reputation and your bank balance.
With Belfast rapidly emerging as a global tech hub, local businesses are under increasing pressure to meet strict data compliance standards. We help Northern Irish companies implement the rigorous defences required to protect client data and achieve industry-standard certifications like Cyber Essentials.
