Cybersecurity for Critical Infrastructure
Critical infrastructure has a security problem that most vendors have not solved. The tools designed for enterprise IT do not belong in power substations, water treatment plants, or pipeline control rooms. And the consequences of getting this wrong are not a data breach — they are a physical event.
The threat is real and it is here now
In 2021, an attacker used remote access to alter chemical levels at the Oldsmar water treatment facility in Florida. In 2022, Sandworm bricked ICS devices across 30 Polish energy sites using default credentials. In 2024, CISA and the FBI issued joint advisories warning that nation-state actors had pre-positioned themselves inside U.S. critical infrastructure — not to steal data, but to be ready to cause disruption on demand.
These are not hypothetical threats. They are documented incidents involving the same types of environments your organization operates.
Why standard cybersecurity fails in critical infrastructure
Most cybersecurity was designed for IT environments — systems that can be patched, updated, and rebooted. Critical infrastructure is different in every way that matters.
PLCs and RTUs run decades-old firmware. You cannot install an agent on a device that controls a turbine. You cannot reboot a water pump to apply a security update mid-operation. And you cannot accept a security tool that causes a process disruption — in these environments, that disruption can mean physical harm or service outages affecting millions of people.
The Purdue Model assumed air gaps that no longer exist. Most critical infrastructure today has some form of remote access, vendor connectivity, or IT/OT network convergence. The isolation that was supposed to be the security is gone — and most security tools have no answer for what happens inside the zone once an attacker is already there.
PacketViper: built for critical infrastructure from the ground up
PacketViper RSUs (Remote Security Units) are compact, ruggedized appliances that install passively inline at field sites — substations, pumping stations, traffic control cabinets, manufacturing cells. No agents on controllers. No cloud dependency for enforcement. No active scanning that could trip a PLC.
OT protocol-native enforcement
Deep packet inspection for Modbus, DNP3, BACnet, S7COMM, NTCIP, EtherNet/IP, IEC 61850, and OPC-UA — with field-level command visibility. PacketViper understands the difference between a legitimate Modbus read and a command that should not be there.
Autonomous enforcement inside the zone
When a threat is detected inside an OT zone, the response has to happen there — not at a boundary firewall, not after a SOAR playbook runs, not after an analyst approves an action. PacketViper blocks and isolates at point of contact, inside the zone, in milliseconds.
Deceptive responders for OT environments
Deceptive responders mimic legitimate OT assets — PLCs, RTUs, SCADA endpoints — drawing attackers away from real infrastructure and generating high-fidelity, false-positive-free alerts. Any interaction with a deceptive responder is by definition unauthorized. No tuning required.
Fail-safe by design
Hardware bypass mode ensures traffic continues uninterrupted even if the RSU loses power or encounters a fault. Operations never stop because of us.
Sectors we protect
PacketViper is deployed in electric utilities and power generation, water and wastewater treatment, oil and gas pipelines, manufacturing and industrial automation, traffic control systems, building automation systems, and federal government facilities.
If your environment cannot afford downtime, cannot accept agents on legacy devices, and cannot wait for a human to respond before damage occurs — this is what we built.
Built for environments that cannot fail.
