This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

3 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • Network security: did not complete in this scan.
  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

AppLovin holds a strong market position in the mobile advertising technology sector, leveraging a broad portfolio of products and subsidiaries to serve app publishers and advertisers. Their business model focuses on providing mediation platforms, user acquisition engines, and analytics tools that enable clients to optimize revenue and growth. The company benefits from strategic partnerships, such as with Adjust, and maintains a robust ecosystem of SDK networks and DSPs. Growth indicators include comprehensive product offerings, active resource centers, and customer testimonials. The website's content and structure support clear communication of value propositions and market differentiation.

Security posture

The website exhibits a mature security posture with enforced HTTPS, multiple security headers, and no exposed sensitive information. However, there is no explicit security policy or incident response information available on the site, which could be improved to enhance transparency and readiness. No vulnerabilities or outdated libraries were detected in the provided content. Privacy compliance is well addressed with comprehensive privacy and cookie policies, including GDPR considerations. The absence of a vulnerability disclosure or security.txt file is a minor gap. Overall, the security maturity is high but could benefit from more explicit documentation and contact channels for security incidents.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance transparency by detailing data retention policies and privacy compliance measures.
  5. Regularly audit third-party scripts and tracking tools to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built on WordPress CMS, utilizing modern JavaScript libraries such as jQuery, jQuery UI, Slick Carousel, and Magnific Popup for UI components and interactivity. It employs lazy loading for images and videos to optimize performance. SEO is enhanced by Yoast SEO plugin and structured data in JSON-LD format. The site is mobile-optimized with responsive design and accessibility considerations. Hosting details are not explicit but likely involve enterprise-grade cloud infrastructure. Performance is fast with minimal render-blocking resources. Technical risks are low, with no visible deprecated technologies or security flaws in the analyzed content.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
