Cyzag Field

Cyzag Field is the app for the person walking the plant. Three things, done properly: rounds, forms and tasks. Captured where the work happens — tank farms, jetties, process units and classified areas. WHERE COVERAGE ISN'T COMING In a classified area, network infrastructure is a certification exercise of its own. Plenty of sites simply don't have it, and never will. Cyzag Field treats that as the permanent condition rather than the exception. A full shift of readings, forms, photos and notes is held safely on the device and synced when you're back in range, with the audit trail intact. BUILT FOR CERTIFIED HANDHELDS Cyzag Field runs on the ATEX and IECEx certified devices your teams already carry, including handhelds from ecom, Bartec and i.safe. Glove mode, hardware buttons and sunlight-readable layouts are assumed, not bolted on. IT DOES LESS, ON PURPOSE Three things that work with the network down beat twenty that need a connection. Rounds you can complete, forms you can submit, tasks you can raise at the point you see the problem — not two hours later from memory at a desk. PART OF THE CYZAG PLATFORM Rounds, forms and task types are configured centrally in Cyzag by the people who own the process. Completed work lands in the same records and audit trail your team already uses. There is no second system to keep in step. Cyzag Field requires a Cyzag account. Cyzag is an operational intelligence platform used in industrial settings such as chemical manufacturers, refiners, terminals and marine operators.
