Onyx and you

The customer has a central role

Faster yet safer

With Onyx One Qualification, you have a successful workflow for qualifying your contractors and subcontractors. It is a secure, fast and safe way of qualifying, partially automatic, but without you losing control….

More certainty, fewer queues

Your contractors and subcontractors are qualified and approved? With Onyx One Registration, every third party entering your site is registered in advance and for a certain period of time. In case of problems or incidents, access can easily be denied.

The safety training revisited

Are your safety rules known and followed? Or is security training limited to watching a gate film and/or signing an A4 sheet? Thanks to Onyx One Training, your safety policy becomes truly effective. Get to know safety, adapted to your company’s specific requirements.

The efficiency in communication

Onyx One Communication ensures centralized, transparent and traceable communication. The tool avoids data silos and simplifies communication with contractor managers.

Auditproof at all times

Human error is reduced to a minimum with the Onyx One Tracking module. Most of the steps in the tracking process happen fully automatically, such as tracking certificate expiration dates and training.

The customer has a central role

Onyx One is a “Software as a Service” solution, and we take our service as seriously as our software. We are committed to providing you with quality support before, during and after implementing Onyx One.
