To choose an IT provider in Ireland, compare them on four things: how fast they respond (in writing), what the monthly fee covers and excludes, who actually does the work, and how easily you could leave. Ask for references from businesses like yours, and check that they will sign a GDPR data processing agreement. ERS IT Solutions has run IT for Irish businesses from Blanchardstown, Dublin 15 since 1983, and our average client relationship lasts more than ten years.
What are the benefits of managed IT services?
The main benefits of managed IT services are fewer outages, faster fixes, better security and a predictable monthly cost. Instead of paying someone to come out after something breaks, a managed service provider monitors your systems, patches them, backs them up and answers staff questions every day. You also get a team of specialists for less than one full-time hire.
The benefits of a managed service provider, in practical terms:
- Problems caught early. Monitoring spots failing disks, full storage and missed backups before staff notice.
- Security basics done every month. Patching, endpoint protection and Microsoft 365 settings are someone's job, not an afterthought.
- A known cost. One monthly fee for agreed work, with projects quoted up front.
- Cover for every skill. Networks, cloud, security and licensing sit with people who do them daily.
- No single point of failure. Holidays and sick days do not stop support.
What are the benefits of outsourcing IT services?
Outsourcing IT means a business can run without hiring and managing an IT team. The benefits are cost (one fee instead of salary, PRSI, training and tools), access to a broader range of skills, and continuity when people leave. The trade-off is that you rely on a supplier, so the contract and the relationship matter.
We compare the numbers in in-house IT vs managed IT in Ireland.
Managed service provider vs outsourcing: what is the difference?
Outsourcing is the broad idea of paying an outside company to do work. A managed service provider is one type of outsourcing where the provider takes ongoing responsibility for running your IT for a monthly fee, with monitoring, maintenance and agreed service levels. Break-fix contractors are also outsourced IT, but they only act when called.
So all managed IT is outsourced, but not all outsourced IT is managed. The question to ask a provider is simple: are you responsible for keeping things working, or only for fixing them when I ring?
MSP vs CSP: what is the difference?
An MSP (managed service provider) runs and supports your IT. A CSP is usually a cloud service provider, such as Microsoft Azure or AWS, that hosts infrastructure. In Microsoft terms, CSP also means Cloud Solution Provider, a partner programme for managing Microsoft cloud subscriptions. ERS IT Solutions is an MSP and a Microsoft Cloud Solution Provider.
In practice, many Irish businesses use both: Microsoft or another cloud platform hosts the services, and the MSP sets them up, secures them and supports the people using them.
What questions should you ask an IT provider before signing?
Ask questions that force specific answers, not sales language: written response times, what the fee excludes, who does the work, what security tools are included, who owns your admin accounts, and how you leave. Then ask for two references from businesses your size and phone them. These twelve questions cover most of what goes wrong in Irish IT contracts:
- What is your average response time, and is it written into the SLA?
- What does the monthly fee include, and can I see the exclusions list?
- Who will actually handle our tickets, and where are they based?
- Do we get a named account manager?
- What hours is the helpdesk open, and what happens out of hours?
- How often will you visit on site, and what does a visit cost if it is not included?
- How do you patch, back up and test restores, and will you show us the reports?
- Which security tools are included (endpoint protection, email filtering, Microsoft 365 monitoring)?
- Will you sign a GDPR data processing agreement, and which subcontractors will touch our data?
- Who owns the admin accounts and documentation?
- What is the contract length, notice period and exit process?
- Can we speak to two clients of our size and sector?
A good provider will answer all twelve without hesitation. ERS gives every outsourced IT client a dedicated account manager and clear SLAs as standard, and our engineering team is based in Ireland.
What should an IT support SLA include?
An SLA should set out priority levels, response and resolution targets for each level, support hours, how to log a ticket, escalation contacts, and how performance is reported. It should also say what happens when targets are missed. Response time (someone starts work) and resolution time (it is fixed) are different, so check which one is promised.
We cover SLA clauses and contract terms in detail, with a checklist you can use as a template, in our IT support contract and SLA guide.
Which contract terms matter most?
Contract length, notice period, exit support and data handling matter most, because they decide how hard it is to leave. Check for auto-renewal, exit fees, and a written commitment to hand back all passwords, documentation and data. Under GDPR Article 28, a provider that processes personal data for you must work under a written contract with set terms.
Article 28 requires that contract to cover confidentiality, security measures, use of subcontractors, help with data subject requests, and deleting or returning data at the end. If a provider has no standard data processing agreement, that is a warning sign.
For larger firms, supplier security is also a legal question. The EU NIS2 Directive requires in-scope organisations to manage supply chain security, including their relationships with direct suppliers and service providers. As of 28 October 2026, Ireland's National Cyber Security Bill to transpose NIS2 had not been introduced in the Oireachtas, and the NCSC says the NIS2 registration and incident reporting portals will open once the law is in place.
What are the risks of outsourcing IT services?
The main risks of outsourcing IT are poor service with no easy way out, losing knowledge of your own systems, and handing data to a supplier with weak security. All three can be managed. Insist on written SLAs, keep ownership of admin accounts and documentation, ask for regular reports, and check the provider's own security credentials.
Ireland's National Cyber Security Centre recommends a register of third parties with access to your systems or data, with due diligence so they protect your data at least as well as you do. An MSP belongs on that register. ERS holds Cyber Essentials certification and is a member of Cyber Ireland.
Red flags when choosing an IT provider
Walk away, or at least ask harder questions, if you see any of these:
- No written response times, or "best efforts" only.
- A monthly price with no exclusions list.
- Reluctance to give references.
- The provider keeps the admin passwords and will not share them.
- Long contracts with automatic renewal and exit fees.
- No data processing agreement.
- Every problem is blamed on a third party.
- A different engineer every time, with no notes on your setup.
That last pair is common. Our managed IT page describes the pattern we see when clients come to us: delayed responses, recurring problems, inconsistent support staff and blame on third parties.
How do you compare "best", "top" and review lists of MSPs?
Top 10 lists, "best MSP" rankings and claims to be the best IT service company in the world are mostly marketing. A provider that suits a 300 person enterprise may be wrong for a 15 person practice. Use lists only to build a shortlist, then judge each provider on response times, scope, references from businesses your size, and how they handle your questions in the first call.
Reviews help when they name the business and describe a real outcome. ERS has more than 100 five-star customer testimonials, and our case studies name the client and the result, such as PPI, where report run times went from over 4 hours to minutes.
How do you switch IT provider without disruption?
Switching IT provider goes smoothly when the new provider takes stock of everything before the old one leaves. Give notice under your current contract, collect every admin password and document, let the new provider audit your systems, then hand over in a planned window. Most of the risk is in passwords and accounts nobody wrote down.
- Read your current contract. Note the notice period and any exit obligations.
- List what you have. Use the audit checklist below.
- Collect credentials. Admin accounts for Microsoft 365, domain registrar, DNS, firewall, backup, Wi-Fi and line-of-business software.
- Choose the new provider and sign a data processing agreement.
- Onboarding audit. The new provider documents, secures and updates the environment.
- Cut over. Remove the old provider's remote tools and accounts, and change shared passwords.
- Review after 30 days. Check ticket times and reports against the SLA.
ERS starts every managed service with a thorough onboarding and site audit. The JMB case study shows what that looks like after a previous provider's fixes had failed.
IT infrastructure audit checklist before you switch
Copy these lines into a spreadsheet and fill them in. It is the same ground a new provider will cover at onboarding:
- Users and licences: every account, who uses it, which Microsoft 365 plan.
- Devices: laptops, desktops, phones, tablets, printers, with age and operating system.
- Servers: physical and virtual, operating system version and support end date.
- Network: internet lines, firewall, switches, Wi-Fi, VPN, guest network.
- Cloud services: Microsoft 365, SharePoint, Azure or AWS, other SaaS.
- Backup: what is backed up, where, how often, and when a restore was last tested.
- Security: endpoint protection, MFA coverage, email filtering, admin accounts.
- Suppliers: phone system, broadband, software vendors, their contacts.
- Domains and DNS: registrar, renewal dates, who holds the login.
- Documentation: network diagram, passwords vault, known issues.
Any server or PC on an unsupported operating system goes straight to the top of the list. See Windows 10 and Windows Server end of support.
