Where Zero Trust for Machines Is Applied

Operant helps industrial and critical infrastructure operators secure the systems that run our world. Governing how equipment, sensors, and connections authenticate and communicate, without rearchitecting what's already running.

These are the most common ways operators apply Operant's Trust Fabric today.

Securing SCADA & Industrial Control Systems

The Challenge

SCADA protocols DNP3, Modbus, IEC 61850 were designed decades before authentication was a consideration. They carry commands and telemetry with no concept of verifying who or what sent them.


Why Traditional Controls Fail

Network segmentation and firewalls can restrict where traffic comes from, but they can't verify what sent it. The protocols themselves have no identity to check.


How Operant Helps

Operant carries native protocol authentication directly with DNP3, Modbus, and IEC 61850 traffic every scada transaction signed and independently verifiable at the protocol level itself.


Outcomes

  • No standing dependency on network segmentation alone

  • Reduced blast radius and lateral misuse

  • Granular allow/deny per command per device

Extending Zero Trust to Connected Devices & Remote Access

The Challenge

Sensors, monitoring systems, and remote vendor connections are multiplying faster than any manual segmentation project can track each one a new relationship someone has to configure, credential, and eventually forget to rotate.


Why Traditional Controls Fail

VPNs and static credentials can secure a connection at setup, but they don't scale every new device means another manual configuration, another shared secret aging quietly in the background.


How Operant Helps

Operant establishes a dedicated, authenticated connection for every device and relationship automatically point-to-point, re-verified, and replicable across fleets of devices. 


Outcomes

  • Per-device isolation that scales without manual configuration
  • No long-lived, unrotated credentials sitting idle
  • Third-party vendor access control

Built for What's Coming: Crypto-Agility & Automated Response

The Challenge

Operators face two converging deadlines: today's threats moving at machine speed, and a 2030–2031 federal mandate to migrate critical infrastructure to post-quantum cryptography often on hardware that wasn't built for either.


Why Traditional Controls Fail

Most security architectures assume today's cryptography is permanent and that response requires a human watching a dashboard. Neither assumption holds as quantum-capable threats and machine-speed attacks both accelerate.


How Operant Helps

Operant is built crypto-agile able to swap cryptographic algorithms, including post-quantum standards without replacing infrastructure. The Trust Controller gives operators a single console to pause a compromised connection or rotate credentials the moment something looks wrong, with automated response on the roadmap as trust grows.


Outcomes

  • Ready for PQC migration mandates without a hardware refresh
  • Faster containment of compromised connections
  • A security foundation that adapts as both threats and standards evolve
