The grid is a target.
Treat it like one.
PacketViper secures electric utility OT environments – substations, SCADA, energy management systems – with preemptive inline enforcement that protects grid operations without disrupting them.
A 9-second cyberattack took down Ukraine’s power grid for hours. The technique is documented. The threat is global.
The Problem
Nation-state actors are already inside US utility networks. Pre-positioning is real.
The Volt Typhoon campaign, documented by CISA and NSA, specifically targeted US critical infrastructure including electric utilities for pre-positioning – establishing persistent access designed to activate during a geopolitical crisis. NERC CIP provides a compliance framework. But compliance is not security. An environment can pass a CIP audit and still have the lateral movement pathways and unmonitored substation connections that made the Ukrainian attack possible.
Pre-Positioning: Attackers Are Already Inside
Volt Typhoon established persistent access to US utility infrastructure designed to activate during a geopolitical crisis – not for immediate disruption. Passive visibility detects reconnaissance after the fact. You need AMTD that makes pre-positioning costly and detectable at first contact.
Unmonitored Substation Connections
Distributed substation infrastructure creates monitoring gaps at exactly the points where attackers need to operate. The Ukrainian attack simultaneously hit multiple substations – the coordination required visibility and access at each distributed location without central oversight detecting the activity.
NERC CIP Compliance ≠ Security
A utility can pass a CIP audit and still have the flat OT network segments, unmonitored remote access sessions, and undetected lateral movement pathways that enabled the Ukrainian attack. CIP tells you the floor. PacketViper tells you whether the floor is actually there.
How It Works
Inline enforcement designed for the power system – DNP3-native, substation-aware
PacketViper deploys across the utility OT architecture – at the corporate/operational boundary, at substation connections, at energy management system interfaces – enforcing inline without disrupting power system operations.
DNP3 Protocol Enforcement – Power System Native
DNP3 is the primary protocol for power system communication. PacketViper understands DNP3 natively – what normal communication looks like between master and outstation, what command sequences are operationally valid, what constitutes an anomalous command. A DNP3 Direct Operate command sent from an unexpected source to a substation RTU triggers enforcement immediately – before it executes.
AMTD – Defeats Volt Typhoon-Style Pre-Positioning
Nation-state actors conducting pre-positioning reconnaissance encounter fake substation interfaces, fake RTU responses, and deceptive system banners. Their reconnaissance maps a network that doesn’t exist. Every probe reveals their presence and burns their time. The sustained unusual access that pre-positioning requires becomes detectable and costly rather than invisible.
Remote Access Behavioral Monitoring
Vendor and maintenance access sessions are required for utility operations but represent significant attack surface. Geographic enforcement, time-of-day controls, and behavioral monitoring apply to every remote session. The Ukrainian attack required months of undetected remote access that would have been anomalous against a behavioral baseline – PacketViper flags exactly that pattern.
Substation RSU Deployment – Autonomous Enforcement at Distributed Locations
PacketViper RSU units deploy at distributed substations, switching stations, and generation facilities – each operating autonomously while contributing to a centralized operational picture. Enforcement at each substation continues whether or not the WAN connection to the operations center is active.
Federation – Synchronized Policy Across All Utility Locations
A threat detected at one substation immediately influences protection at all others. Centralized management synchronizes policy across substations, switching stations, and generation facilities with a single operational view. The Ukrainian attack coordinated across three sites simultaneously – PacketViper responds to threats at the same speed, across all locations at once.
NERC CIP Evidence Generation: Continuous tamper-evident logging for all enforcement actions, policy changes, and user activity – NERC CIP compliance evidence generated as standard output from normal security operations. No separate compliance tooling. No audit reconstruction.
Proof Points
Validated against documented attack techniques
Nation-state APTs are in US utility networks right now. Pre-positioning is a documented, current threat. Passive visibility isn’t enough – you need inline enforcement that fires before the activation command, and AMTD that makes reconnaissance too costly to complete.
Power system operations are safety-critical. The security layer doesn’t touch controllers, doesn’t interfere with protection systems, and doesn’t require configuration changes to SCADA or EMS. Enforcement is invisible to every operational system it’s protecting.
NERC CIP compliance is the floor, not the ceiling. Board-level responsibility for grid security in a post-Ukraine, post-Volt Typhoon environment requires a defensible preemptive posture – not just audit evidence, but demonstrated enforcement capability.

NERC CIP-015-1 is the North American Electric Reliability Corporation standard for Internal Network Security Monitoring in high-impact BES Cyber Systems. PacketViper's inline monitoring, Deceptive Responders, and comprehensive audit logging directly satisfy the monitoring and evidence requirements of this standard without requiring passive-only monitoring tools.
PacketViper deploys RSUs at substations with native DNP3 protocol support, enabling accurate detection of unauthorized commands or anomalous ICS traffic without generating false positives that could disrupt legitimate SCADA communications. Autonomous operation means substations remain protected even during WAN outages.
Yes. PacketViper is explicitly designed as a compensating control for legacy OT devices that cannot be patched. By enforcing at the network layer, PacketViper shields vulnerable devices from direct threat exposure – blocking attacks, confusing reconnaissance, and enforcing behavioral boundaries – without requiring any modification to the protected equipment.
