How to prevent clickjacking
- Prefer CSP frame-ancestors with allowed origins
- Legacy: X-Frame-Options: DENY or SAMEORIGIN
- Apply consistently across sensitive routes
Across 7,440 recent scans, 59.0% have no X-Frame-Options or CSP frame-ancestors directive set. Clickjacking protection is rarely enforced.
What is clickjacking?
Clickjacking overlays your site with a hidden frame to trick users into unintended clicks. Proper framing policies stop hostile embeds.
Implementation examples
Once you've identified the gap, applying the fix is straightforward. Here are the three configurations developers reach for most often.
Nginx
add_header Content-Security-Policy "frame-ancestors 'self'" always;
add_header X-Frame-Options "DENY" always;Apache
Header always set Content-Security-Policy "frame-ancestors 'self'"
Header always set X-Frame-Options "DENY"Node.js (Express + Helmet)
app.use(
helmet({
contentSecurityPolicy: {
directives: { frameAncestors: ["'self'"] },
},
frameguard: { action: "deny" },
})
)Tool-specific questions
X-Frame-Options or frame-ancestors?
Use CSP frame-ancestors. XFO is legacy, so avoid conflicting settings.
Can I allow specific partners?
Yes - list partner origins in frame-ancestors, and periodically review them.

FAQ
Frequently asked.
What is Barrion and how does it enhance website security?
Barrion is a security testing and monitoring platform for engineering teams, covering three products: passive DAST that continuously watches your live web apps and APIs, SAST via GitHub that scans your codebase for secrets, insecure patterns and vulnerable dependencies, and AI pentesting that runs active, agent-driven attacks with proof-of-exploit. Findings come with step-by-step fixes you can ship immediately.
How safe is Barrion to use for security testing?
Every default Barrion scan is 100% passive and read-only. We never submit forms, brute-force endpoints or interact with state-changing routes, so it's safe to run against production.
What types of security issues does Barrion identify?
Barrion is a security testing and monitoring platform, so coverage spans three surfaces. Passive DAST flags misconfigurations across TLS/HTTPS, security headers, cookie flags, CORS policy, DNS records, email authentication (SPF/DKIM/DMARC), network exposure and common web hygiene issues. SAST via GitHub finds secrets in code, insecure patterns and vulnerable dependencies. AI pentesting adds exploitable findings like SQL injection, XSS and broken access control with proof-of-exploit.
What specific security checks does Barrion perform?
Barrion checks TLS/HTTPS configuration, HTTP security headers, cookie flags, CORS policy, DNS and email authentication records, network exposure and common web hygiene issues, then prioritises them by severity with clear remediation.
What is Barrion's smart crawling?
Smart crawling automatically discovers the pages and endpoints of your app so scans cover the surface that matters, without you manually listing every URL.
How often does Barrion perform security scans?
Manual scans on demand. Continuous monitoring runs automatically on Essential (weekly+) and Business (daily), and alerts you the moment a new issue appears.
Is Barrion suitable for security testing of all business sizes?
Yes. Barrion is a security testing and monitoring platform, with passive DAST, SAST via GitHub and AI pentesting available to solo developers, startups, scale-ups and enterprise security teams alike, without adding headcount.
How does Barrion handle data security and privacy during security testing?
Scans are passive and read-only by default, and we never store or expose sensitive data from your application. Pentests are rate-limited and non-destructive, designed to confirm exploitability without altering data or affecting availability.
What if I'm not satisfied with Barrion's security testing service?
Paid plans start with a free trial, and you can cancel anytime. If something isn't right, contact us and we'll make it work for your team.
How does Barrion help with SOC 2, ISO 27001, NIS2, and other compliance frameworks?
Barrion produces audit-ready PDF and CSV reports suitable for SOC 2, ISO 27001, PCI DSS and NIS2, ready to share with auditors, customers and your board.
