Your Traveler's Browsers Are the Target
- 01
Client-side attacks go undetected
Your website loads dozens of 3rd party scripts (marketing tags, data integrations, analytics). One bad script exposes your users to attacks.
- 02
Legacy tools miss dynamic attacks
Fraud tools and separate payment portals don't monitor the browser. CSPs and crawlers are evaded by attacks with dynamic JavaScript.
- 03
Compliance pressure is increasing
Airlines & transit platforms fall under PCI DSS, GDPR, and regional data laws that hold organisations accountable for 3rd party scripts.
- Monitor & secure every script to block malicious code from reaching users
- Protect sensitive flows like ticket booking and loyalty program pages
- Prevent violations of PCI DSS, GDPR, and HIPAA
- Reduce fraud with browser-layer forensics

Common Client-Side Attacks on Airline & Transit Platforms
Magecart & E-Skimming
Code hidden on document upload or payment pages steal card data and personal information
Expired Domains
Attackers purchase expired domains of scripts on your site to change code from an approved source.
Software Supply Chain
A breach in one of your trusted providers (analytics, chatbots, marketing tool) infects your entire site.
Dynamic JavaScript
Advanced threats target sessions with specific criteria (e.g. IP address) to evade traditional detection.
PII Leaks
Unmonitored scripts exfiltrate sensitive personal information such as passport data and travel details
Ad Injections
Injected ads or pop-ups inside the browser trick travelers into clicking fraudulent booking links
Why Attackers Target Airline & Transit Platforms
High value data: Stealing login credentials to purchase flight tickets and or hijack loyalty miles are lucrative assets for attackers to go after.
Multiple "trusted" scripts: marketing tags, chatbots, code libraries, and script tag managers are all entry points for browser attacks.
Easy to hide: Payment and check-in flows already request sensitive data that attackers want - card details, passport numbers, and loyalty program credentials.
Apps run client-side: As airline platforms push to mobile first experiences, code is increasingly executed on the browser, widening the attack surface.
