IoT and industrial control system (ICS) security
Modern Workspace > IoT and industrial control system (ICS) security
From smart buildings and sensors to SCADA and PLCs, modern enterprises increasingly rely on connected devices and industrial systems. But most of these assets were never designed with cybersecurity in mind—and they’re now high-value targets for cyberattacks.
Allevio helps organizations assess, segment, monitor, and secure their IoT and ICS environments. We deliver tailored solutions that bridge IT and OT security, reduce attack surfaces, and align with industry frameworks like NIST, IEC 62443, and ISO 27019.
What We Offer
IoT & ICS Risk Assessment
Understand your exposure across connected environments:
- Asset discovery and classification for OT, ICS, IIoT, and smart devices
- Risk mapping by criticality, communication paths, and known vulnerabilities
- Review of existing controls and compensating measures
- Assessment aligned to NIST CSF, IEC 62443, and ISA 99
Network Segmentation & Traffic Control
Limit lateral movement and isolate critical systems:
- Design of VLANs, DMZs, and firewalled zones for OT and IoT
- Deployment of unidirectional gateways, industrial firewalls, and data diodes
- Protocol filtering and whitelisting (Modbus, DNP3, BACnet, OPC-UA)
- Zero Trust segmentation for hybrid IT/OT environments
Threat Detection & Monitoring
See what’s happening across your industrial networks:
- Passive traffic monitoring for anomalies and threats
- Behavioral analytics and threat intelligence for OT protocols
- Integration with SIEM, SOC, and industrial IDS (e.g., Nozomi, Claroty, Dragos)
- Alerting and response playbooks tailored to operational impact
Security Hardening & Governance
Reduce attack surfaces and build defensible environments:
- Secure configuration of PLCs, HMIs, RTUs, and edge devices
- Firmware and patch management workflows for OT
- Role-based access controls (RBAC) and multi-factor authentication
- Development of OT security policies, response plans, and audit frameworks
Supported Technologies & Platforms
- Protocols: Modbus, DNP3, OPC UA, BACnet, PROFINET, MQTT
- Security Tools: Claroty, Nozomi Networks, Dragos, Armis, Cisco Cyber Vision
- Firewalls & Segmentation: Fortinet Rugged, Palo Alto Industrial NGFW, Belden, Hirschmann
- Compliance: IEC 62443, NIST SP 800-82, ISO 27019, NIS2, ISA/IEC standards
Use Cases
