Looking after Irish businesses since
Sound familiar?

Most businesses come to us with the same five frustrations.

  • 01You get a different person every time — and explain the problem from scratch again.
  • 02You put off calling because every call turns into an invoice.
  • 03You think your Microsoft 365 is backed up — but nobody has ever shown you.
  • 04You've had a phishing email that looked frighteningly real.
  • 05You're not sure your setup would pass a cyber-insurance questionnaire.

A real person, fast

We answer the phone — or call back within 30 minutes — and resolve virtually every ticket the same day.

The result: an IT problem costs you minutes, not half a day.

A dedicated engineer who knows you

You always speak to someone who already knows your systems, your history and your business.

The result: you never explain yourself twice.

One flat fee, unlimited support

From €59 per computer per month, with unlimited remote support. Call as often as you need.

The result: no surprise invoices, ever.

Fixed before you notice

24/7 monitoring and patching raise a ticket the moment something looks wrong — often before anyone in the office knows.

The result: fewer Monday-morning disasters.

The numbers

A full IT department for less than a part-time hire

A part-time IT person in Ireland costs €30,000–€40,000 a year before PRSI, equipment and training — and they're one person who gets sick and goes on holiday. CastCom Essentials for a 10-person office is about €7,080 a year, with a whole team and 24/7 monitoring behind it.
