A Unified Security Platform for Modern Grid Protection
As substations become more digital and interconnected, cybersecurity becomes a top priority for utilities and system integrators. Threats are evolving quickly, regulations are tightening, and traditional “single-appliance” cybersecurity architectures no longer scale. Firewalls, IDS systems, jump servers, log collectors, and domain controllers often end up fragmented across multiple devices—hard to manage, hard to secure, and costly to maintain.
The Welotec RSAVP solves these challenges by consolidating all network security functions onto one high-performance, virtualized platform built specifically for primary substations.
All Cybersecurity Tools, One Hardened Platform
The RSAVP can host a complete cybersecurity stack in virtual machines, including:
Core Protection Components
-
Next-generation firewalls (virtual)
Fortinet FortiGate VM, Palo Alto VM-Series, Check Point CloudGuard -
Intrusion Detection Systems (IDS)
OMICRON StationGuard, Radiflow iSID VM, Rhebo OT Monitoring
Secure Access & Identity
- Jump servers / remote access gateways
- Active Directory domain controllers
- Certificate and key management servers
Monitoring & Forensics
- SIEM connectors & syslog collectors
- Event storage & reporting servers
- Network packet capture and analysis tools
Everything runs within isolated VMs on the same physical RSAVP hardware — with strong separation, simplified patching, and easy lifecycle management.
Why RSAVP Is the Ideal Cybersecurity Platform
- High-core processors → perfect for IDS deep packet inspection
- Up to 512 GB RAM → supports many security VMs simultaneously
- IEC 61850-3 & IEEE 1613 certified → resilient against EMI, temperature, vibration
- FPGA-based PRP/HSR redundancy → ensures uninterrupted inspection during failures
- Redundant architecture → security services stay online even if one server fails
- Optimized for real-time workloads → no packet loss or slowdowns
The result is a robust, substation-ready cybersecurity hub.
Benefits for Utilities and System Integrators
- Centralized access control
- Unified patch management
- Network segmentation
- Continuous monitoring and logging
- Strong identity and certificate management
- Firewall appliances
- IDS appliances
- Log servers • Jump servers
- Management servers
All are replaced by virtual machines running on 1–2 RSAVPs.
-
Faster Response & Easier Maintenance
Security patches, configuration updates, and backups are performed:
- Centrally
- Consistently
- With snapshot-based rollback
- Without taking devices offline
- Better visibility of substation traffic
- Easier change control
- Less wiring and fewer single points of failure
- More predictable lifecycle planning
Making Substations Cyber-Resilient
Cybersecurity must be integral to the substation architecture—not an afterthought. By consolidating key security applications into a dedicated virtualized platform, utilities gain improved resilience, stronger compliance, and simplified management.
The Welotec RSAVP provides exactly that: A secure, robust, flexible cybersecurity foundation engineered for modern and future digital substations.
