How cside Protects Airline & Transit Platforms 
Client-Side Intelligence
Our hybrid proxy architecture provides comprehensive client-side protection specifically designed for the unique challenges of airline and transit platforms.
Your Traveler's Browsers Are the Target
Your website loads dozens of 3rd party scripts (marketing tags, data integrations, analytics). One bad script exposes your users to attacks.
Fraud tools and separate payment portals don't monitor the browser. CSPs and crawlers are evaded by attacks with dynamic JavaScript.
Airlines & transit platforms fall under PCI DSS, GDPR, and regional data laws that hold organisations accountable for 3rd party scripts.
Our hybrid proxy architecture provides comprehensive client-side protection specifically designed for the unique challenges of airline and transit platforms.
Our proxy monitors the activity of every script, blocking malicious code from reaching users on your platform.
PCI 6.4.3 & 11.6.1 requirements with script inventory, change detection, justifications, and audit-ready reports.
Identify what personal data each third-party script has access to and where it's sent. Stay compliant with GDPR + HIPAA by preventing PII leaks.
Our system creates device fingerprints for every user session, enabling detection of suspicious activity from bots or humans at the browser level.
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.
"Our experts can conduct a client-side vulnerability assessment and provide a customized recommendation."

Common Client-Side Attacks on Airline & Transit Platforms
Code hidden on document upload or payment pages steal card data and personal information
Attackers purchase expired domains of scripts on your site to change code from an approved source.
A breach in one of your trusted providers (analytics, chatbots, marketing tool) infects your entire site.
Advanced threats target sessions with specific criteria (e.g. IP address) to evade traditional detection.
Misconfigured or malicious scripts violate your privacy control policy to exfiltrate sensitive PII.
Fake login or consent fields displayed over UI elements to harvest login credentials.
Don't Wait for a Data Breach or Audit Failure
cside tells me everything I need to know about a script, and makes sure they are safe to show to the user. It's really made me realize how big of a problem 3rd party script security is, and there are no other solutions I've tried that dive as deep as cside.
