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

RevBid, operated by RevMedia GmbH, is a specialized header bidding platform that helps publishers maximize their ad revenue through advanced programmatic solutions. The company targets a diverse range of publishers including crypto websites, content sites, and online tools or games. Their business model focuses on providing flexible, no-lock-in contracts and dedicated support to publishers worldwide, positioning themselves as a trusted partner in the ad tech space. The website is professionally designed with clear navigation and good content relevance, supporting their market positioning as a niche ad network with a global footprint. Technically, the website employs modern web technologies including Bootstrap, Font Awesome, jQuery, and integrates key advertising and analytics scripts such as Prebid.js, TikTok Pixel, and Google Analytics. Hosting is provided by Vautron Rechenzentrum AG, and the domain is registered with transparent WHOIS data consistent with the company’s identity. Performance and mobile optimization are good, though accessibility features are basic. SEO practices are adequately implemented. From a security perspective, the site uses HTTPS with a good SSL configuration but lacks important security headers and DNSSEC. There is no published security policy or incident response contact, and no cookie consent mechanism is present, which are areas for improvement. No critical vulnerabilities or exposed sensitive data were detected. Privacy compliance is basic with a privacy policy present but no explicit cookie consent. Overall, the website presents a moderate risk profile with good business credibility and technical implementation but some gaps in security and privacy compliance. Strategic recommendations include enhancing security headers, enabling DNSSEC, implementing cookie consent, and publishing security and incident response policies to improve trust and compliance.

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

  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

    • 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

RevBid operates in the ad tech sector focusing on header bidding solutions for publishers. Their competitive advantage lies in their flexible, no-lock-in contracts and support for diverse publisher types including crypto and content sites. Revenue streams likely come from ad network commissions and partnerships. The company targets publishers seeking to optimize ad revenue with a trustworthy partner. Growth indicators include over 5000 active monetized sites and presence on six continents. Partnerships with known ad tech companies and testimonials support their market credibility. The company is relatively new (founded 2023) but shows professional branding and a clear strategic focus.

Security posture

The security maturity level is moderate. HTTPS is enforced with a good SSL setup, but the absence of security headers such as Content-Security-Policy and Strict-Transport-Security reduces the security posture. No security.txt or incident response contacts are published, limiting transparency for vulnerability reporting. Privacy compliance is partial with a privacy policy but no cookie consent mechanism. No vulnerabilities or exposed sensitive data were found in the HTML content. The company should prioritize implementing security headers, DNSSEC, and formal incident response processes to enhance security culture and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Enable DNSSEC on the domain to improve DNS security.
  3. Add a cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  4. Publish a security policy and incident response contact information (e.g., security@ or abuse@ email).
  5. Regularly audit third-party scripts and tracking pixels to ensure privacy compliance and minimize user tracking.

Technical notes

Notes

The website uses a modern and common tech stack with Bootstrap, Font Awesome, jQuery, and Prebid.js for header bidding. It integrates third-party analytics and advertising scripts asynchronously to optimize performance. Hosting is stable with a reputable provider. The site is mobile optimized and SEO friendly with proper meta tags. However, accessibility features are basic and could be improved. No CMS was detected, indicating a custom or static site build. Performance is moderate, with potential for improvement by optimizing script loading and caching strategies. Technical risks include missing security headers and lack of DNSSEC which could be exploited in DNS spoofing or clickjacking attacks.
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.
