Built for the energy edge

Real protections that installers and operators can deploy in minutes.

Modbus / MQTT DPI

Inspect, validate, and filter fieldbus and broker traffic. Block malformed function codes, topic abuse, and unauthorized writes.

Keywords: Deep Packet Inspection, allow-lists, function-code control

Zero-Trust Segmentation

Isolate inverters, BESS, and EVSE with policy-based micro-perimeters. Only known identities and flows pass.

Keywords: mTLS, identity-aware policies

OTA Updates

Secure over-the-air firmware and ruleset updates with signed packages and staged rollouts.

Keywords: signed firmware, rollback

NIS2-Aligned Controls

Support for policies and logging aligned with NIS2 readiness: asset inventory, audit trails, incident hooks.

Keywords: compliance posture, audit logs

Installer-Friendly

DIN-rail mount, low power, wizard-based setup, and presets for popular inverters and EVSE.

Keywords: quickstart profiles

Fleet & SOC Hooks

Northbound APIs and syslog/webhook export for fleet portals, SIEM/SOAR, and DSO/DSR telemetry.

Keywords: API, syslog, webhooks

DIN-rail by design

Purpose-built hardware for plant rooms, cabinets, and wall boxes. Policies protect inverters, BESS controllers, EV chargers, and site gateways without re-wiring.

  • Profiles for Modbus registers & MQTT topics
  • Identity-aware access for maintenance sessions
  • Local fallback mode for safety operations
