These 5 IT companies in Belfast outsmarted my hackers!
Tired of IT support teams who only mess with your brain with tech jargon or just never answer your calls? Me too. It was so frustrating for a non-tech-savvy person like me to deal with hackers on my art website.
I once tried to deal with it on my own—and all I did was make everything worse! Now, I leave all the tech stuff to the pros. I’ve looked up almost every IT specialist in the city, and I’m pretty sure I’ve got some of the best on my list today.
Whether you’re a blogger or non-profit worker, these are the best IT companies in Belfast to consult and keep your computers, websites, or systems running smoothly.
1. Precept IT

Address: Forsyth House, Cromac St
Phone: +44 800 122 3010, [email protected]
Business hours:
- Mon-Fri: 7:00am – 9:00pm
- Sat-Sun: 8:00am – 6:00pm
Precept IT is a Belfast IT company known for its fast remote helpdesk. It offers many services, like managed IT support, cloud services, and more.
I find it convenient that it supports a wide range of platforms, letting it customise support to any client. For example, its tech team can help you, whether you use Linux or Windows.
One client I talked to also praised a specialist here for resolving his problem within 30 minutes! For me, this shows the company’s efficiency, especially for emergencies.
Moreover, I appreciate that it’s transparent with costs since there are detailed pricing packages on its website. You’ll find starter IT support packages for various needs, like 24/7 remote monitoring, discounted site visits, and cybersecurity.
But since the company offers several all-in-one packages, I think its solutions might seem overkill for smaller businesses or nonprofits.
Attentive, speedy, and efficient
“Precept customer service is always attentive, speedy and efficient. All staff are knowledgable, friendly and solution oriented. Thank you for being a trusted provider.”
-Ms. Shelly Dolan, Google Review
Friendly & supportive
“Precept team are fantastic – always there with a solution in a friendly and supportive way! Thank you”
-Ms. Hannah McKimm, Google Review
2. Cybit

Address: Unit 16, Floor 0, Catalyst, The Innovation Center, Queens Rd
Phone: +44 330 162 6410, 03308 221346, [email protected] (general inquiries), [email protected] (support)
Business hours:
- Mon-Fri: 9:00am – 5:30pm
- Sat-Sun: Closed
Cybit is one of the most innovative Belfast IT companies, as it focuses on using data and AI (artificial intelligence) to help clients make smarter decisions. Its core offerings also revolve around cybersecurity, managed IT, and cloud solutions.
And if you’re someone who’ll sleep through all the tech talk, its team can give a detailed yet simplified explanation of the IT issues.
More specifically, its experts guide clients through several phases (Assess, Advise, Deliver, and Support) to be well-organised and thorough. This ensures you’ll be aligned with the team here throughout—less room for mistakes.
Not to mention, this option is reliable with its ISO-compliance (International Organization for Standardization). Basically, the company uses internationally approved methods for protecting clients’ businesses from cyber threats.
Nonetheless, this company offers mostly high-end strategies, so smaller organisations might find its solutions more expensive than those of others in the city.
So friendly

3. ITNI LTD

Address: Scottish Provident Building, 7 Donegall Square W, Floor G
Phone: +44 28 9066 3611, [email protected]
Business hours:
- Mon-Fri: 9:00am – 5:00pm
- Sat-Sun: Closed
Should you need a one-stop shop for all things IT assistance in Belfast, I bet ITNI LTD is among the first ones to consider!
Its core services look endless, offering 24/7 managed IT support, hardware setup and maintenance, and cloud services. They also have Microsoft Office 365 support, cybersecurity, and web design and hosting.
On top of designing and hosting over 200 websites, it also gives training sessions for users. This can really give clients peace of mind in maintaining their sites regularly.
And if you’re hesitant about letting tech people go to your residence or business, I appreciate that this company’s staff are Police Service of Northern Ireland- or PSNI-cleared for your peace of mind.
However, you won’t see its prices listed on its website. I think this makes cost comparisons with other options harder, given that there are plenty of IT services offered here.
Be sure to reach out during business hours, though, as the staff isn’t available on weekends—unless you’re already a paying client for its managed IT support.
First-class service
“Can’t thank Ben and the team enough for everything they’ve done for me recently in work. Owning a busy retail shop, you need to have your till system working. Ours crashed, but thanks to Kai of ITNI he was out very quickly to get our system up and running! Got us out till working, then came back to upgrade the system to make sure we don’t run in to the same problem again! First class service from them all! Can’t thank them enough. 5 star service.”
-Mr. Jordan Dalzell, Google Review
Hands-on & reliable
“We’ve been using ITNI for our IT systems and day-to-day support for several years now. Their hands-on approach, combined with reliable remote support, has been a huge help to our business. It’s allowed us to focus on our own work while leaving the IT side in their capable hands. Thanks to the whole team for the excellent service!”
-Mr. Reggie Blain, Google Review
4. Data Forensics

Address: 117 Ormeau Rd
Phone: +44 28 9543 8520, 079 3818 2909, [email protected]
Business hours:
- Mon-Fri: 8:00am – 2:30pm
- Sat: 8:00am – 10:30am
- Sun: Closed
Deleted your important files by accident? Data Forensics is the Belfast IT company that’s in the business of helping clients recover damaged or lost data.
I find it convenient that this company is heavily focused on data recovery, especially since this includes hard disks, USB sticks, SSDs, memory cards, and the like.
If your case is really urgent, it offers priority data recovery within 1 to 2 days—some even within the same day!
Besides the free diagnostics and quotes, I appreciate that the team gives case tracking tools (and even screenshots!) for progress updates. This signals expert communication with clients.
What’s more, its techs don’t charge for unsuccessful recoveries, which makes clients feel confident of its high success rate.
That said, remember that this company only specialises in data recovery. Should you need general IT support, it’s best to explore other options here.
Excellent background knowledge
“We had a brilliant experience with Nico. He has excellent background knowledge and understands all the issues which arise with various commercial brands such as seagate. He was able to access our drive which had rigor mortis and then also returned our drive to the manufacturer and got us a new one. So he recovered all the data and transferred it onto a free new drive. Happy days and thank you Nico.”
-Mr. Ronan McCloskey, Google Review
Fantastic retrieving
“Fantastic service! Retrieved my wedding photos from a damaged drive, so very relieved!! Great communication throughout process and helpful advice on how to store my pics safely in future. Can’t recommend Nico enough!!”
-Ms. Dawn McCabe, Google Review
5. Endeavour Information Solutions

Address: Units 2 & 3, Hawthorne House, 6 Wildflower Way
Phone: +44 28 9031 1010, [email protected]
Business hours:
- Mon-Fri: 8:30am – 5:30pm
- Sat-Sun: Closed
Having trouble with Microsoft 365? Endeavour Information Solutions has been a certified Microsoft Solutions Partner for over 30 years, making it one of the most capable choices in the city.
Its team is also skilled in handling SharePoint, Dynamics 365, Azure, and other cloud solutions that help clients effectively and safely streamline their work.
So if you want help going digital, it’s helpful that this company specialises in making personalised apps. The team focuses on UX (user experience) and AI or data integration, so the apps would be built competitively for the most efficient use.
They also guarantee not charging extra for out-of-hours work and travel expenses, which means the techs are quite upfront with fees.
But since this option heavily focuses on Microsoft issues, businesses or organisations that rely on other tech ecosystems (like Apple) won’t find much use in its offerings.
Extremely knowledgeable
“Staff are extremely knowledgeable with tonnes of experience in Microsoft products and development”
-Mr. Fionn Condren, Google Review
Helpful staff
“Great service from friendly, helpful staff”
-Mr. Eamon Kelly, Google Review
