Cell Register - 2026 Pricing, Features, Reviews & Alternatives

Built for the heads of manufacturing, controls engineers and OT security leads who are asked what each machine can reach and who answers for it.

Go into the next change review with a zone for every machine. Cell Register reads the CMMS export, maintenance asset list or commissioning register you already keep and places each asset in a zone class: cell, line, plant supervisory, site business or safety. It derives a target security level from the class and raises it where remote access is declared.

Know what a wrong action costs. For each asset you see what it acts on physically and how far a wrong action reaches: a person in the cell, a batch, a line or a release. Adaptive controllers are counted separately from fixed-program ones, and so are the remotely reachable assets.

Take duties, not opinions, to the integrator. Tick the regimes that reach you and each asset carries the rows that attach: asset-owner duties under IEC 62443, the NIST SP 800-82 overlay, EU AI Act deployer duties where a controller adapts, and what the owner holds under the EU Machinery Regulation. Supplier rows are written as questions to ask, never as your duty.

Start without a platform on your network. The register runs in your browser and nothing is sent anywhere until you save.

Pricing: the free plan reads up to eight assets per run with no account. Solo is USD 29 a month for one person and adds the zone and conduit sheet, integrator questions, Machinery document checklist, board summary and saved registers. Team is USD 99 a month for the whole organisation.
