Protect passenger records, filter airport and in-flight WiFi, secure reservation systems, and defend loyalty programs with DNS filtering across 90 million categorized domains and 58 content categories.
Airlines and travel companies manage some of the most sensitive personal data in any industry. DNS filtering provides a critical security layer across airports, aircraft, hotels, and booking platforms.
PNR records contain passport numbers, payment details, travel itineraries, and contact information for millions of travelers. DNS filtering prevents this data from being exfiltrated through compromised systems or DNS tunneling attacks.
Airport lounges and in-flight WiFi connect thousands of passengers to shared networks. DNS filtering provides content control and content filtering on these networks without requiring any software installation on passenger devices.
GDS platforms and booking engines are critical infrastructure that process billions in transactions. DNS filtering blocks access to credential restricted domains targeting airline reservation system operators and travel agents.
Aviation and travel face unique cyberweb-based risks that DNS filtering addresses at the network foundation
Passenger Name Records and Advance Passenger Information contain identity documents, billing data, and travel patterns that are highly valuable on dark web markets. DNS filtering prevents data leakage from reservation and check-in systems.
Modern airports operate dozens of interconnected networks serving airlines, retail, ground handling, and government agencies. DNS filtering provides a unified security layer across this complex ecosystem without disrupting operations.
Satellite-based in-flight connectivity has limited bandwidth and high latency. DNS filtering operates efficiently within these constraints, blocking malicious content without consuming precious satellite bandwidth on full content inspection.
Frequent flyer accounts contain billions in accumulated miles. restricted domains targeting loyalty program credentials enable account takeover and fraudulent redemption. DNS filtering blocks these credential harvesting campaigns.
Fraudulent domains mimicking airline and OTA booking pages collect payment information from travelers. DNS filtering identifies and blocks fake booking sites, protecting both airline brands and passenger financial data.
Airlines operate across dozens of jurisdictions with varying data protection laws. DNS filtering enforces region-aware policies ensuring compliance with EU PNR Directive, TSA regulations, and local data sovereignty requirements simultaneously.
Purpose-built features for securing travel infrastructure from ground to air
Deploy content filtering on airport passenger WiFi networks. Block unsafe content, and inappropriate content categories while allowing travelers full access to travel-related services and business productivity tools.
Bandwidth-efficient DNS filtering optimized for satellite connectivity. Protect passengers from content risks and enforce content policies during flights without impacting the already constrained in-flight internet experience.
Restrict Global Distribution System access to authorized networks and block known credential restricted domains targeting Amadeus, Sabre, and Travelport systems. Prevent unauthorized booking modifications and data access.
Block domains associated with loyalty program credential restricted content, miles brokering, and account takeover infrastructure. Protect the billions in accumulated value stored in frequent flyer and hotel rewards programs.
Manage DNS policies across airport lounges, city offices, maintenance facilities, and crew bases from a single console. Location-specific policies adapt to the security needs of each facility type.
Monitor DNS traffic across all travel network segments. Track content risk trends, identify targeted restricted content campaigns against your brand, and generate compliance reports for aviation regulators.
How airlines and travel companies deploy DNS filtering to protect operations and passengers
A major airline deployed DNS filtering on their in-flight WiFi serving 200,000 daily passengers. Content filtering blocked inappropriate categories while content classification prevented passengers from accessing restricted content and unsafe content domains at 35,000 feet.
An international airport network filtered DNS across 45 airline lounges. Separate policies for business travelers and general passengers ensured appropriate content access while blocking all malicious domains on shared networks.
A travel agency conglomerate integrated DNS filtering into their operations network. Agents were protected from accessing fraudulent supplier domains, and fake booking confirmation restricted pages were blocked across all branch offices.
An airline frequent flyer program with 50 million members deployed DNS filtering to protect the program's web infrastructure. Credential restricted domains targeting their loyalty portal were blocked, reducing account takeovers by 91%.
A cruise operator deployed DNS filtering across their fleet's satellite internet. Passenger WiFi was filtered for content and content risks while crew networks received stricter policies preventing access to bandwidth-heavy streaming domains.
A ground services company operating at 120 airports used DNS filtering to protect their check-in, baggage handling, and ramp operations networks. Critical airline system access was secured while employee internet was appropriately filtered.
Protect passenger data, secure in-flight connectivity, and defend booking infrastructure with enterprise DNS filtering built for the travel industry.
