IT consultancy and outsourcing
We plan and build IT systems, test them against attack and close the gaps, and write software where nothing off the shelf fits. If you would rather not hire the staff, we also run the help desk, the network, the backups and the move to cloud.

How it works
On the consultancy side we plan and implement infrastructure, select hardware and software, design network architecture, and optimise what you already run rather than replacing it by reflex.
On security we assess, harden and monitor. That means testing systems against realistic attack, closing what the test finds, and staying on for incident response rather than handing over a report and leaving.
Where nothing off the shelf fits we write the software and integrate it with your existing systems. Where you would rather not carry the headcount, we run the help desk, network and server administration, backup and recovery, and the migration to cloud.
