Smart city traffic.
Yesterday’s security.
Unacceptable gap.
PacketViper secures intelligent traffic systems – ITS, NTCIP, SCADA-connected controllers – with enforcement that fits inside a roadside cabinet and operates autonomously.
One compromised intersection controller can cascade into citywide gridlock. That’s not a hypothetical.
A laptop and a key. Four days of gridlock.
In 2006, two disgruntled engineers disrupted Los Angeles traffic signals for four days using a laptop and physical access to a control cabinet. They didn’t need sophisticated malware. They didn’t need a nation-state budget. They needed a laptop and a key.
The ITS market has grown dramatically since then – $12 billion in 2025, projected to $19 billion by 2030. What hasn’t grown at the same rate: the security protecting it. Most traffic controller systems still run NTCIP and SNMP in cleartext. Many use the same default credentials across all intersections citywide. Networks are flat and unsegmented – a breach at one cabinet reaches every cabinet.
Iranian state actors were documented reconnoitering US smart city traffic infrastructure in 2020. This is not a future threat. It’s a current one.
When traffic controllers fail, ambulances can’t reach hospitals. Fire trucks get stuck in gridlock. An all-red outage turns every intersection into a four-way stop simultaneously. The physical consequences of a cyber attack on traffic infrastructure are immediate, visible, and potentially fatal.
Cabinet-rack RSUs. Protocol-native enforcement. No reconfiguration required.
PacketViper OT360 with Remote Security Units is purpose-built for the traffic cabinet environment. RSUs are rugged, form-factor appropriate for cabinet rack installation, and deploy as transparent bridges on existing controller network connections – no reconfiguration of existing equipment, no changes to NTCIP or controller configurations.
Each RSU understands ITS protocols natively: NTCIP, SNMP, and the traffic-specific protocol stack. It monitors for anomalous commands – protocol-level enforcement, not just IP/port allow-deny. If a command is sent that’s outside normal operational bounds, enforcement fires at the RSU, locally, without waiting for the central operations center to respond.
Geo-fencing rules prevent traffic management commands from being accepted from outside defined geographic regions – a command that looks like it’s coming from a regional traffic management center but originates from outside the expected network space gets flagged and blocked immediately.
SCADA integration surfaces security events into the existing traffic management center displays via Modbus. Traffic operations staff see security alerts in the systems they already monitor. No new tool. No new training.
Purpose-built for ITS field deployment
Protocol-Native ITS Enforcement
NTCIP, SNMP, and traffic-specific protocol stack awareness – enforcement at the command level, not just IP/port filtering.
Cabinet-Rack RSU Form Factor
Designed for field deployment in roadside enclosures – not server room appliances shoehorned into a cabinet.
Geographic Command Fencing
Traffic management commands validated against expected source geography – commands from outside defined network regions are blocked immediately.
Compartmentalization via AMTD
Breach at one cabinet can’t propagate freely to others – the watertight bulkhead principle applied to ITS networks.
SCADA Integration
Security alerts surface in existing traffic management center displays via Modbus – no new tools, no new training for operations staff.
Autonomous Operation
RSUs enforce locally if central management connectivity is interrupted – field enforcement never depends on central connectivity to function.
Live in production with state DOT customers
“Far fewer security incidents, enforcing geo-fenced rules they simply couldn’t do with their old firewall.”– State DOT customer, live production deployment
Production deployment with state DOT customer – real ITS infrastructure, real traffic, measurable security improvement.
No reconfiguration required – transparent bridge installs without touching controller configurations or NTCIP operation.
Cabinet breach detection – physical access to roadside enclosures triggers immediate detection and containment response.
Every stakeholder in ITS security
For Security Teams
ITS networks are distributed, physically accessible, and running legacy equipment. RSUs give you coverage at every node without requiring central connectivity to enforce.
For OT Operators
Zero changes to controller configurations or NTCIP operation. The RSU is invisible to the systems it’s protecting – operations continue exactly as before.
For Leadership
No federal mandate yet for ITS cybersecurity – but the threat is current and the liability exposure is real. Proactive deployment costs a fraction of the incident response, legal, and PR cost of a traffic network compromise.

Talk to us before the incident. We’ll show you what the gap looks like in your ITS network and what an RSU deployment would cost versus what a breach would.
ITS networks face risks including unauthorized access to traffic signal controllers, manipulation of variable message signs, interference with connected vehicle infrastructure, and ransomware targeting transportation management centers. These attacks can cause traffic disruptions, accidents, and public safety incidents.
PacketViper supports NTCIP (National Transportation Communications for ITS Protocol) natively, enabling accurate enforcement decisions for traffic management communications. It deploys at traffic operations centers and remote field device sites, providing autonomous protection at unmanned intersections and signal cabinets without requiring on-site security staff.
