What Your IT Provider Is Responsible For — And What They Are NotÂ
Most professional services firms operate under a quiet assumption: that their IT provider is handling it. Handling what, exactly, is rarely defined.

INNOSEC provides managed IT services for law, accountancy, finance and architecture firms in Belfast, Bangor and across Northern Ireland. We watch for threats 24/7, secure every device and account from day one, and take ownership of your IT and its roadmap. Problems get caught before they cost billable hours.
Most IT providers wait for something to break. We work to make sure it doesn’t, and when something does, you already know exactly what to expect.
Most firms believe they are covered because someone answers the phone when something breaks. But break-fix support and a managed helpdesk are reactive by design, they respond to problems, they do not prevent them.
Managed IT services work the other way. INNOSEC monitors, maintains and plans proactively, so issues are caught before they cost you downtime, and your IT strategy is built alongside your business goals, not bolted on after the fact.
If your provider's first action is always fixing a problem rather than preventing one, you are paying for break-fix support, not managed services.
Response time and resolution time are different things. Without clarity on both, you cannot know what level of service you are genuinely getting.
For law, accountancy, finance and architecture firms, every hour of downtime is an hour that cannot be billed. Reactive support turns technical delays into lost revenue.
Without a dedicated strategic voice, your technology decisions happen in isolation from your business goals, growth plans, and compliance obligations.
Our Managed IT Services bring continuous monitoring, responsive support, security-by-design, and strategic planning together under one team, built around Microsoft 365 as the foundation.
We take ownership of your IT. You get senior IT leadership, a technology roadmap tied to your business goals, and one team accountable for delivering it. When something needs a decision, you know who owns it.
Continuous, proactive monitoring that catches issues before they become downtime.
Responsive help desk support with clear, transparent SLAs you can actually explain.
Security-by-design built into every device, account and configuration from day one.
A technology roadmap we own with you, tied to your firm's goals and kept current as they change.
Continuous monitoring and maintenance that catches problems before they cause downtime.
Clear, transparent SLAs with defined response and resolution times, not vague promises.
Senior IT leadership that owns your technology roadmap and is accountable for delivering it.
Microsoft 365 Business Premium as the foundation, configured, secured and managed properly.
Identity, access control and data protection built in from day one, with 24/7 threat monitoring and response.

Practical support aligning your IT to GDPR, Cyber Essentials, and sector-specific requirements.
One point of accountability for the vendors and licences your firm depends on.
Support that strengthens an existing internal IT team rather than replacing it.
We support legal, accountancy, finance and architecture practices in Belfast, Bangor and across Northern Ireland, and firms in Ireland and the UK. They need strong technology foundations without building a large internal IT team.
We are a strong fit when downtime has a real cost, whether that is billable hours, client trust, or regulatory exposure, and reactive support is no longer good enough.
As the CEO of 3173, I had the privilege of working closely with Alan McBurney. Under Alan’s visionary leadership, we experienced a transformative shift in our IT operations that not only streamlined our processes but significantly enhanced our security and operational resilience.
For over 20 years, Alan McBurney has been our trusted IT advisor, guiding our small architectural practice through numerous technological advancements. As we continue to grow and evolve. Alan has now introduced us to his new venture, INNOSEC, were he brings the same level of expertise and tailored service we’ve come to rely on.
I’ve had the pleasure of working with Alan in various capacities over the years, and his ability to handle complex IT challenges efficiently has always impressed me. His expertise shone brightly during a critical phase at Seatruck Ferries, where he led a significant enhancement of our systems, ensuring robust security and seamless operations. His solutions not only solved our immediate problems but also positioned us for future scalability and success.

Selecting the right Managed Service Provider (MSP) can determine whether your business runs efficiently or constantly wrestles with IT issues.
Managed IT services are a proactive model of IT support, continuous monitoring, maintenance and strategic planning that prevents problems, rather than a reactive model that only responds once something has broken.
Break-fix support responds when something goes wrong. Managed services actively monitor your environment to catch and resolve issues before they cause downtime, and include ongoing strategic planning alongside day-to-day support.
Yes. Our co-managed IT option is built to strengthen an existing internal team with specialist support, security and monitoring, rather than replace it.

Yes. We’re based in Bangor and support firms in Belfast and across Northern Ireland. We also support firms in Ireland and the UK.
Managed IT starts from £500 a month + VAT. The price depends on your number of users and what your firm needs. We confirm it once we’ve looked at your setup.
The best first step is to book a Managed IT Assessment. We will review your current setup and show you where reactive support may be costing you more than you realise.
