Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
HSTS header is missing
Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.
No Content-Security-Policy header found
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
No <main> landmark found
Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.
46 third-party resources (100% of weight)
Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment

Figures combine localized regulatory fine ceilings, search/conversion value priced against local CPC, and bandwidth waste estimates. Results depend on implementation quality and audience composition. Not legal or financial advice.
Conversion barriers
8 barrier(s) likely increasing bounce by ~28%.
- Page takes 7.0s to loadUsers abandon at ~3s — you're 4.5s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
- No Content-Security-Policy headerHigher XSS blast radius — one compromised script can exfiltrate the checkout form→ Ship a reporting-only CSP first, then enforce once violations are clean
- Viewport disables user zoomVisitors with low vision can't read the page — and some jurisdictions treat this as a legal risk→ Remove user-scalable=no; drop maximum-scale if it's below 2
- No Open Graph tagsLinks shared on LinkedIn / Slack / Facebook show bare URLs — referral clicks drop→ Add og:title, og:description, og:image, og:url to the page head

Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside a web browser.
Styled components is a CSS-in-JS styling framework that uses tagged template literals in JavaScript.
Manage session history with JavaScript
Lodash is a JavaScript library which provides utility functions for common programming tasks using the functional programming paradigm.
Moment.js is a free and open-source JavaScript library that removes the need to use the native JavaScript Date object directly.
React is an open-source JavaScript library for building user interfaces or UI components.
UmiJs is a scalable, enterprise-class frontend application framework that supports both configuration and conventional routing while maintaining functional completeness, such as dynamic routing, nested routing, and permission routing.
core-js is a modular standard library for JavaScript, with polyfills for cutting-edge ECMAScript features.
jQuery is a JavaScript library which is a free, open-source software designed to simplify HTML DOM tree traversal and manipulation, as well as event handling, CSS animation, and Ajax.
qiankun is a JS library who helps developers to build a micro frontends system.
Observations (4)
Runtime exposed via X-Powered-By header
The X-Powered-By header reveals 'styled-components 6.1.1'. Remove this header in production to reduce information leakage.
jQuery loaded alongside a modern framework
Both jQuery and React are loaded. Modern frameworks handle DOM manipulation natively. jQuery may be unnecessary and adds ~30KB to the page weight. Check the Performance tab for bundle analysis.
No build tool detected
A framework (Day.js) was detected but no bundler was identified. The build tool may not be detectable from output patterns, or the site may use the framework's built-in bundler.
Complex technology stack detected
11 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
