Sound familiar?
IT shouldn’t be the thing that keeps you up at night
If any of these ring true, it’s time for a partner who fixes the causes, not just the symptoms.
- Calling for help and getting a voicemail or an overseas call centre
- The same problems coming back month after month
- Worrying that one phishing email could take the business down
- Not knowing if your backups would actually work after a hurricane
- CIMA, the Data Protection Act or your cyber insurer asking questions you can’t answer
- Unpredictable IT bills and surprise project costs
- Cabling, phone and IT contractors blaming each other
- No plan for where your technology needs to be in two years

Questions
Common questions
Do you provide on-site IT support in Grand Cayman?
Yes. Our engineers live and work in Grand Cayman, so when something needs hands-on attention we come to you. Most problems don’t need a visit at all: we fix them remotely through secure tools, often while you’re still on the phone. Our helpdesk is open 8:00am to 5:00pm, Monday to Friday, and emergency calls are answered 24/7.
Where is our data stored?
Microsoft 365 data stays in your Microsoft tenant, and our nightly backups of it are stored in a hurricane-rated data centre in the Cayman Islands for three years. Server backup and hosting are available on-island too.
We already have an IT person or overseas IT team. Can you help?
Yes — that’s co-managed IT. We act as your local hands and eyes, take on the work your team doesn’t have time for, and add security testing and strategy on top. Learn about co-managed IT.
Can you help with our cyber insurance?
Yes. Our plans are designed around the controls insurers ask for most — MFA, endpoint detection and response, backups and staff training — and we help you complete insurer questionnaires about the controls we manage.
What if we want to leave?
You can leave at the end of any term with 60 days’ notice. Whenever you leave, we hand over all your admin credentials, documentation and data. We never hold them hostage.
What does the free network assessment include?
An engineer visits your office and reviews your network, firewall and Wi-Fi, your servers and computers, your Microsoft 365 or Google Workspace setup, your backups, and key security controls such as multi-factor authentication, patching and email protection. We also check what your business exposes to the internet. You get a short written report in plain English: what’s working, what’s at risk and what we’d fix first, and we walk you through it. There’s no cost and no obligation.
