Automatically Always Know Your Access
My IEDs: secure remote IED access for substations
Always know who accessed which device. Always know that connections are authorized. Always know that sessions are logged.
Authorized users connect to any IED instantly, without knowing connection details, while every session is logged and permissioned.
About PowerSYSTEM Center
PowerSYSTEM Center is a multi-function IED management platform that enables critical infrastructure asset owners to securely and centrally manage their large install base of many different intelligent electronic devices (meters, relays, RTUs, etc) deployed throughout their entire transmission and distribution system.
Core Platform Capabilities
- NERC CIP Intermediate System for IED Access Control
- Unified Relay Event File Collection and Archiving
- Unified Asset Monitoring
- Unified Data Historian Interfaces
Key Benefits
- Ensure compliance with regulatory requirements
- Integrate all devices, regardless of manufacturer or model
- Eliminate human performance issues and errors
- Protect your existing device investment
Used by dozens of the largest T&D companies in the US, PowerSYSTEM Center provides a central source of truth for all your devices with automated baseline monitoring, remote access control, and automatic scheduled password changes.
Who it serves
Built for Protection Engineers, OT Security teams, and Substation Maintenance at DSOs and TSOs. Replace manual connection procedures with instant, secure, audited access to every device in your fleet.
Problem in the field
Accessing IEDs across hundreds of substations means juggling connection parameters, credentials, and procedures for every device. Staff waste hours trying to connect instead of doing actual maintenance. Without centralized control, there is no way to enforce who can access which device, or to prove it during an audit.
How PowerSYSTEM Center helps
PowerSYSTEM Center brokers all IED connections so users never need to know IP addresses, ports, dial-up strings, or device credentials. Users authenticate once with their existing directory credentials and MFA. PowerSYSTEM Center then automatically navigates through multiple layers of network devices and security to reach the target IED. Permissions are set per user, device, application, task, or command, so each person only sees and accesses what they are allowed to. No additional substation hardware or client software is required: PowerSYSTEM Center works with your existing IT infrastructure.
Single sign-on
PowerSYSTEM Center integrates with Microsoft Active Directory for single sign-on. The only credentials users need are their network username and password provided by their IT department. Once authenticated, users see only the IEDs they are permitted to access based on their role and permissions.
Connection types
PowerSYSTEM Center supports connections to substation devices via Ethernet and serial paths, including low-bandwidth and dial-up links. The system knows which connection type each IED requires and automatically handles the connection process. Users spend more time managing and maintaining IEDs and less time trying to connect to them.
Evidence and control
Every session is recorded: who connected, to which device, when, for how long, and what actions were taken. Centralized access management means system administrators control permissions from one place, and unauthorized access attempts are logged and flagged.
Frequently asked questions
What connection types are supported?
PowerSYSTEM Center supports Ethernet, serial, and dial-up connections to substation devices. The system automatically determines the correct connection method for each IED and handles all intermediate network hops, firewalls, and security layers.
Do users need client software installed?
No. PowerSYSTEM Center does not require client software installation on user workstations, and no additional hardware or software is needed at the substation level. It works with your existing IT infrastructure.
How are access permissions managed?
Permissions can be set on a per-user, per-IED, per-application, per-task, or per-command basis. Users only see the devices they are authorized to access. Administrators manage all permissions centrally through PowerSYSTEM Center.
Does it work with devices from different vendors?
Yes. PowerSYSTEM Center is vendor-neutral and supports IEDs from SEL, GE, ABB, Siemens, Beckwith, and others. You are not locked into a single vendor's access solution.
How does single sign-on work?
PowerSYSTEM Center integrates with Microsoft Active Directory. Users log in with their existing network credentials. Once authenticated, PowerSYSTEM Center handles all device-level authentication automatically, so users never need to know individual device passwords.
Supports the practices you need to demonstrate: IEC 62443-3-3 account and session control, NERC CIP electronic access management, NIS2 access governance, and NIST SP 800-82 remote access requirements.
