Key points
- Corsha announced Folio on Wednesday as a new module for its Industrial Identity Security Platform.
- The tool automates the creation of operational maps and documentation using live network and access data.
- Folio aims to replace manual, tedious documentation processes with real-time visibility into OT system communications.
Corsha has launched Folio, a new module designed to automatically map industrial networks and document how operational technology systems connect and communicate in real time.
How it unfolded
- On Wednesday, Corsha announced the release of Folio, a new addition to its Industrial Identity Security Platform.
- The company stated that Folio automatically creates and updates operational maps based on live network data rather than static designs.
- Corsha CEO Anusha Iyer highlighted that the module uses AI and machine learning to automate the tedious work of daily operations documentation.
Who is affected
Security and operations teams in industrial enterprises are the primary users of this new module. According to Corsha, these teams often struggle with outdated or non-existent documentation, which makes risk management and incident preparation difficult. The tool is designed for organizations that need to maintain compliance with frameworks such as IEC 62443, NERC CIP, and Zero Trust. By providing an accurate view of how systems actually run, Folio targets the gap between designed architecture and current operational reality.
What happens next
Teams using the Corsha platform can now generate derived hardware lists, real-time connection maps, and Microsoft Visio data flow diagrams. Corsha states that these artifacts allow security and network teams to share accurate information across departments. The company emphasizes that this real-time visibility helps organizations spot risk and drift, prepare for incidents, and modernize with confidence. The module relies on Corsha Gatekeepers to capture identities, connections, and data flows on the OT network.
The background in plain language
Industrial networks often lack accurate documentation because environments change frequently while records remain static. This drift creates security blind spots, as teams cannot see unauthorized connections or outdated systems. Manual mapping is slow and error-prone, leaving organizations vulnerable. Automated tools address this by continuously monitoring live traffic to build an accurate, current map of devices and their communications. This real-time visibility helps teams understand exactly what is connected, how data moves, and where potential risks exist without relying on outdated diagrams or guesswork.
What to do and how to stay safe: Corsha
- Review current operational technology documentation to identify gaps between recorded architecture and actual network connections.
- Evaluate whether existing monitoring tools provide real-time visibility into device identities and data flows within the OT environment.
- Check compliance requirements for frameworks like IEC 62443 or NERC CIP to ensure documentation processes meet audit standards.
- Monitor for automated solutions that can reduce manual effort in maintaining accurate network maps and system records.
