0–100, higher is better. How it is calculated

Adyoulike is a mature native advertising technology platform founded in 2010, offering a comprehensive suite of native advertising solutions including automatic stories, retail stories, native social, video, and display ads. Positioned as a leading global SSP in native advertising, it targets brand advertisers and premium publishers worldwide. The company has a strong market presence supported by multiple international offices and a recent acquisition by OpenWeb, enhancing its market reach and capabilities. Technically, the website employs modern web technologies such as HTML5, CSS3, JavaScript, and jQuery with additional tools like bxSlider and Axeptio CMP for cookie consent management. The site is mobile optimized and SEO friendly, though accessibility features are basic. Security posture is solid with HTTPS enforced and domain transfer protections, but lacks DNSSEC and explicit security policies or incident response contacts. Overall, the website is professional, trustworthy, and compliant with privacy regulations, though improvements in security headers and transparency could enhance its posture further.

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

4 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
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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

  • 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

Adyoulike operates in the technology and media sectors, focusing on native advertising solutions that enable brands to scale campaigns across premium publishers programmatically. Its business model revolves around a supply-side platform (SSP) and marketplace facilitating native ad placements with high engagement formats. The company leverages partnerships with major publishers and DSPs, evidenced by its connected DSP count and premium publisher network. The acquisition by OpenWeb signals strategic growth and integration into a broader digital engagement ecosystem. Revenue streams likely include platform fees, ad placements, and technology licensing. The company targets brand marketers and publishers seeking scalable native advertising solutions. Its competitive advantages include proprietary technology, a global exchange, and a strong portfolio of success stories and industry awards.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and domain transfer protections in place. However, the absence of DNSSEC and lack of published security policies or incident response contacts indicate gaps in transparency and advanced security practices. No vulnerabilities or exposed sensitive data were detected in the content. Cookie consent is managed via a reputable CMP (Axeptio), supporting GDPR compliance. The site does not expose any critical security issues or signs of compromise. To improve, the company should implement security headers, publish a security policy, and provide incident response contact channels to enhance trust and readiness.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement comprehensive security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Regularly audit third-party libraries and scripts to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern and standard technology stack with HTML5, CSS3, JavaScript, and jQuery, supplemented by bxSlider for UI components and Axeptio for cookie consent management. Hosting is managed via Gandi SAS, a reputable registrar and hosting provider. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. Performance is moderate with video content and interactive elements. Accessibility is basic and could be improved. No CMS is explicitly detected, suggesting a custom or static site architecture. The technical implementation is solid but could benefit from enhanced security headers and performance optimizations.
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.
