Eliminated Default Passwords Across 200 Substations

Challenge

Security audit revealed 40% of protection relays still had default passwords. Manual password rotation was inconsistent and poorly documented across multiple vendors.

Solution

Implemented SUBNET's automated password management with post-session rotation and centralized vault storage across SEL, ABB, and GE relay fleets.

Results

100% secure
Default Passwords
Before: 40% remaining
After: 0%

Password Rotation
Before: Manual, quarterly
After: Automatic, per-session
90% faster
Audit Preparation
Before: 2 weeks
After: 2 hours

"The automated password rotation gives us bulletproof audit trails and eliminates the risk of forgotten credentials. Our NERC CIP compliance is now effortless."

Streamlined Emergency Access During Storm Response

Challenge

Hurricane response required 24/7 relay access for multiple teams, but manual credential sharing created security risks and delayed restoration efforts.

Solution

Implemented SUBNET's just-in-time access with approval workflows and session recording for emergency operations across critical substations.

Results

95% faster
Access Approval
Before: 2-4 hours
After: 5 minutes

Automated Asset Discovery Across Legacy Infrastructure

Challenge

Aging infrastructure with incomplete documentation made it impossible to track all connected devices, creating blind spots for security and maintenance planning.

Solution

Deployed SUBNET's automated asset discovery to scan and catalog all IEDs, RTUs, and gateways across serial and Ethernet networks with protocol identification.

Results

63% increase
Device Visibility
Before: 60% known
After: 98% mapped
92% faster

Centralized Management Across Multi-Vendor Environment

Challenge

Managing protection settings across SEL, ABB, GE, and Schneider devices required multiple vendor tools and inconsistent workflows, slowing critical updates.

Solution

Unified all device management through SUBNET's platform with vendor-agnostic interfaces and standardized workflows for mixed-vendor substations.

Results

87% reduction
Tool Consolidation
Before: 8 vendor tools
After: 1 platform
90% faster
Training Time
Before: 3 weeks
After: 2 days
92% faster
Update Efficiency
