Protect connected vehicle communications, secure dealership networks, filter manufacturing OT systems, and safeguard telematics data with DNS filtering across 90 million categorized domains.
Modern vehicles are networked computers on wheels. The automotive industry faces unique cybersecurity challenges spanning connected cars, manufacturing plants, dealerships, and supply chains that DNS filtering addresses at the foundational layer.
Vehicles with cellular connectivity make continuous DNS queries for navigation, telematics, entertainment, and OTA updates. DNS filtering ensures these queries only resolve to legitimate automotive infrastructure, blocking C2 domains that could compromise vehicle systems.
As manufacturing systems become IP-connected, the boundary between operational technology and IT networks dissolves. DNS filtering provides a non-invasive security layer that protects production line controllers without disrupting manufacturing processes.
Automotive supply chains involve thousands of suppliers sharing data through interconnected systems. DNS filtering secures these connections by blocking compromised supplier domains and preventing supply chain attacks at the network resolution layer.
Industry-specific content risks across the automotive value chain that DNS filtering addresses
Vehicle-to-everything communication relies on trusted infrastructure domains. Rogue V2X servers on compromised domains could send false traffic data or emergency alerts. DNS filtering ensures V2X queries only resolve to verified, authorized infrastructure endpoints.
Telematics systems transmit location, driving behavior, and diagnostic data to cloud platforms. DNS filtering prevents telematics data from being redirected to unauthorized collection servers through DNS hijacking or poisoning attacks.
Dealerships handle customer financial data, vehicle ownership records, and manufacturer system access. restricted domains targeting dealership management system credentials are a primary attack vector that DNS filtering blocks proactively.
Automotive manufacturing plants are high-value restricted content targets. A single day of production downtime costs millions. DNS filtering blocks restricted content C2 domains and prevents initial infection by stopping access to unsafe content distribution infrastructure.
Over-the-air software updates to millions of vehicles must come from verified sources. DNS filtering ensures OTA update queries resolve only to legitimate manufacturer update servers, preventing malicious firmware distribution through DNS spoofing.
Tier 1 and Tier 2 suppliers with network access to OEM systems create lateral attack paths. DNS filtering at the supplier integration boundary blocks compromised supplier domains from accessing manufacturer networks.
Purpose-built features securing the entire automotive ecosystem from vehicle to factory
Filter DNS queries from connected vehicle telematics control units. Block access to unauthorized data collection domains while allowing legitimate navigation, entertainment, and OTA update services to function normally.
Apply DNS filtering to operational technology networks in manufacturing plants. Restrict industrial controllers and SCADA systems to approved domains, preventing compromised OT devices from reaching attacker infrastructure.
Manage DNS policies across hundreds of dealership locations from a centralized console. Separate policies for showroom WiFi, F&I department systems, and service bay diagnostics ensure appropriate security per network zone.
Enforce DNS policies on supplier network integrations. Monitor and control which external domains supplier-connected systems can access, reducing the attack surface created by third-party network access to your infrastructure.
Generate compliance documentation for UNECE WP.29 and ISO/SAE 21434 cybersecurity regulations. DNS filtering logs provide evidence of network security controls required for vehicle type approval in regulated markets.
Secure fleet management telematics across thousands of commercial vehicles. DNS filtering prevents fleet tracking data leakage and blocks unauthorized access to vehicle location and operational data streams.
How automotive companies deploy DNS filtering across vehicles, factories, and dealerships
An OEM deployed DNS filtering on their connected vehicle platform serving 2 million vehicles. Telematics DNS queries were restricted to verified backend domains, blocking attempts to redirect vehicle data to unauthorized collection infrastructure.
An automotive manufacturer deployed DNS filtering across 12 assembly plants. Production line controllers were isolated at the DNS layer, preventing restricted content from spreading between IT and OT networks and protecting continuous operations.
A manufacturer pushed DNS filtering to their 800-dealer network. Each dealership received segmented policies for customer WiFi, DMS systems, and diagnostic tools. PCI compliance across the dealer network improved by 55%.
An autonomous vehicle development lab secured their research network with DNS filtering. Test vehicle data, AI training datasets, and proprietary algorithms were protected from exfiltration by restricting DNS resolution to approved research domains.
An electric vehicle charging network operator deployed DNS filtering across 10,000 charging stations. Each station's payment processing and user authentication systems were secured at the DNS layer, preventing data interception attacks.
A major automotive parts supplier deployed DNS filtering to secure OEM data exchange channels. Supplier portal access was verified through DNS-level controls, and compromised test environments were prevented from reaching production OEM networks.
