Five contracts, five invoices, and with every outage the same question: whose problem is it?
With TRON
One partner.
- One point of contact who knows your entire environment
- One contract at a fixed monthly price
- The people who build it also manage and secure it
You don't have to move everything over at once. Start with whatever is causing problems right now, your IT management, for example, and expand when it suits you.
03Case studies
This is what one partner looks like in practice.
The bar under each client shows which of our five areas of expertise we take care of for them. For most it's four or more, and five clients rely on us for everything.
04Software & web
We also build what doesn’t exist yet.
The team that writes your software also hosts, secures and supports it. No handover from developer to IT support team, no ‘that’s a hosting problem’.
