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

RTB House is a technology company specializing in next-generation performance advertising powered by deep learning. Their platform focuses on first-party data to deliver personalized marketing campaigns that drive growth across web and app channels. The company positions itself as a leader in the performance DSP market, offering services such as retargeting, acquisition, engagement, and demand generation. The website demonstrates a strong brand presence with client testimonials, case studies, and a comprehensive privacy and cookie consent framework. Technically, the website is built on modern frameworks including Next.js and React, integrates with marketing and analytics tools like HubSpot, Google Tag Manager, and Fathom Analytics, and uses DatoCMS for content management. The site is well-optimized for performance, mobile responsiveness, and SEO, providing an excellent user experience. From a security perspective, the site enforces HTTPS and includes cookie consent mechanisms aligned with GDPR compliance. However, explicit security headers are not detected, and no public security policy or incident response information is available. The WHOIS data for the domain is not publicly available, which slightly reduces trust but does not contradict the legitimacy indicated by the website content and branding. Overall, RTB House presents a professional and trustworthy digital presence with strong technical and privacy compliance maturity. Strategic improvements in security transparency and direct contact information could further enhance trust and security posture.

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

Business profile

RTB House operates in the technology sector, specifically in digital advertising and marketing technology. Their business model revolves around leveraging deep learning to enhance performance advertising using first-party data. The company targets advertisers, marketers, and agencies seeking advanced retargeting and acquisition solutions. Their market position is that of an innovative DSP provider with a focus on AI-driven personalization. Revenue streams likely include advertising campaign management fees and technology licensing. The presence of global case studies and client testimonials indicates a broad international footprint and a mature partnership ecosystem. The company emphasizes data privacy and compliance, which is critical in their industry. Strategic observations include the importance of maintaining transparency in domain registration and enhancing security disclosures to align with industry best practices.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enforced and a cookie consent mechanism that supports GDPR compliance. The absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the content. The lack of published security policies, incident response procedures, or vulnerability disclosure programs suggests limited transparency in security governance. The WHOIS data absence is a minor concern but does not indicate malicious intent. Overall, the security maturity is adequate for a technology company but could be enhanced by adopting additional security best practices and publishing relevant policies.

Recommendations

  1. Implement and publish comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a formal security policy and incident response plan on the website to improve transparency and trust.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Provide direct company contact emails and phone numbers for sales and support to improve business credibility and user trust.
  5. Review domain registration details and consider making WHOIS information publicly available to enhance legitimacy and trust signals.

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.
