1. Does the SLA have numbers?
"We are fast" is worthless in a contract. Demand response and resolution times by severity, and that a locked workstation is not treated like a server outage. Before comparing, read what an SLA must contain.
Warning sign — the document only appears after much insistence, or sets no times.
2. Is the price fixed or an hour bank?
With an hour bank, the risk is yours. If the balance runs out mid-incident, someone has to approve more hours with operations at a standstill. A mature MSP charges a fixed fee with a closed scope. See how costs are built up in Portugal.
Warning sign — "that is not included" applied to everything that takes effort.
3. Is the team in-house?
Who holds the keys to your servers is a security decision. Confirm that the engineers are on the payroll and that a fixed team looks after your company.
Warning sign — a new face on every visit, with no record of what was done.
4. Do they know about the problem before you do?
This is the decisive test. An MSP sees the disk degrading before the employee notices. Ask for real cases of failures resolved without impact and the list of what is monitored: servers, network, workstations, backups.
Warning sign — no monthly report, or a report that only counts tickets.
5. Does security come in the package?
In 2026, firewall, endpoint protection, secure email, MFA and backups with tested restores are the minimum, not an extra. Decree-Law no. 125/2025 has also brought formal obligations for many companies. See the scope of our managed cybersecurity.
Warning sign — backups nobody has tried to restore. Until then, they are a hypothesis.
6. If you leave, do you take the documentation?
Network, credentials and configurations are your property. A top MSP records everything and hands everything over at the end. It is the most revealing test: a provider that retains clients through opacity will not hand over the file.
Warning sign — "our engineer knows that".
7. Are there engineers to go on site?
Remote access handles almost everything. It does not replace a failed switch, tidy a rack or accompany the carrier. Check the actual coverage and which plan includes site visits.
Warning sign — "we cover the whole country" with no real ability to travel.
8. Do the references answer the phone?
Ask for clients in your sector and of your size. Call them. Public reviews and named cases are worth more than logos on a slide.
Warning sign — references who are never reachable.
