WASHINGTON – October 21, 2026 -- Corsha has launched Folio, a module for its Industrial Identity Security Platform that automatically generates and updates maps and documentation of how operational technology (OT) systems are connected and communicating, replacing manual assessments that the company says take weeks.
Folio draws on live network and access data captured by Corsha Gatekeepers. It records which machines are communicating, when, why and how, and produces derived hardware lists, real-time connection maps and Microsoft Visio data flow diagrams. The outputs are designed for IEC 62443, NERC CIP and Zero Trust frameworks.
Folio targets documentation gaps that slow OT compliance and incident response
Corsha says OT documentation is often missing or has drifted too far from the running environment to be useful. Compliance artifacts built through manual assessments are frequently incomplete or inaccurate, according to the company.
Folio supports three use cases:
- Day-to-day operations: removes manual upkeep of system and network documentation for risk assessment and incident response.
- Continuous compliance: delivers updated system, connection and architecture documentation "in minutes" for hurdles such as Authority to Operate (ATO), Zero Trust and NERC CIP.
- Technology adoption: lets teams assess how robotics, physical AI and predictive analytics would affect brownfield environments before production deployment.
Connection Canvas lets teams design zones and view enforced segmentation
A live Connection Canvas lets teams design boundaries, zones and machine groups while showing active data flows, segmentation and enforced policies. The canvas uses IEC 62443 terminology through to exported assessment artifacts. Folio tracks changes using machine identity, which Corsha says IP addresses alone cannot reveal.
Corsha founder and CEO Anusha Iyer said industrial enterprises need an "accurate, current understanding of every machine and every connection" to modernize safely, and tied Folio to faster incident recovery and compliance that keeps pace with change.
The company claims Folio can cut time spent on compliance activities by orders of magnitude, reduce recovery time from incidents and errors, and eliminate the cost of manually maintaining operations documentation. It provided no benchmark data to support these figures.
Corsha is backed by Ten Eleven Ventures, Razor's Edge Ventures, Booz Allen Ventures and Cybernetix Ventures.
