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

6 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. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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

RTB House operates in the technology sector, providing AI-powered advertising solutions primarily for web and app platforms. Their business model is B2B, focusing on performance marketing and retargeting services that leverage first-party data and deep learning algorithms. The company showcases a global client base with case studies from various industries including automotive, fashion, and real estate. Their competitive advantage lies in proprietary deep learning technology that identifies non-obvious converters and optimizes ad placements without sharing or selling client data. RTB House maintains an active partnership ecosystem and a strong social media presence, enhancing market reach and credibility. Growth indicators include expanding service offerings such as in-app advertising and gaming-focused campaigns. Strategic observations highlight the company's emphasis on privacy compliance and personalized marketing as key differentiators.

Security posture

The website employs HTTPS with a good SSL configuration, ensuring encrypted communications. Cookie consent banners and privacy policies indicate compliance with GDPR and related privacy regulations. However, the site lacks explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options, which could enhance protection against common web attacks. No public incident response or vulnerability disclosure policies are found, and no dedicated security contact information is provided. There is no evidence of exposed sensitive data or vulnerable libraries in the HTML content. Overall, the security maturity is moderate to good, with room for improvement in transparency and technical safeguards.

Recommendations

  1. Implement and publish comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Establish and disclose an incident response policy and provide dedicated security contact channels to improve transparency and readiness.
  3. Consider publishing a vulnerability disclosure or security.txt file to encourage responsible reporting of security issues.
  4. Enhance contact information by providing verified company emails and phone numbers for customer and security inquiries.
  5. Regularly audit third-party scripts and tracking pixels to ensure compliance with privacy regulations and minimize tracking risks.

Notes

The website is built on a modern technology stack featuring React and Next.js frameworks, supported by DatoCMS for content management. It integrates multiple third-party analytics and marketing tools such as HubSpot, Google Tag Manager, and Fathom Analytics, enabling robust data collection and campaign management. Multimedia content is delivered efficiently using Mux Player. The site demonstrates fast performance, excellent mobile optimization, and good accessibility features. SEO is well addressed with proper meta tags, Open Graph data, and structured JSON-LD schema markup. Technical risks are minimal, though reliance on multiple external scripts requires ongoing monitoring to avoid performance degradation or security vulnerabilities.
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.
