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

Blockthrough is a technology company specializing in adblock revenue recovery solutions for digital publishers. Founded in 2015, it serves a global audience of publishers by providing a platform that delivers lighter, nonintrusive ads to users who use ad blockers, thereby helping publishers recover lost revenue. The company holds reputable certifications such as Google Certified Publishing Partner and IAB EU TCF v2.0 vendor status, positioning itself as a trusted partner in the digital advertising ecosystem. The website content is professional and targeted primarily at publishers and media companies seeking to optimize ad revenue while maintaining user experience. Technically, the website is built on WordPress using the Elementor page builder, hosted behind Cloudflare, and employs modern web technologies including jQuery and integrations with HubSpot and Calendly for marketing and scheduling. The site implements a comprehensive cookie consent mechanism via CookieYes, categorizing cookies by purpose and providing users with customization options, indicating a commitment to privacy compliance. Performance and mobile optimization are good, though accessibility features are basic. From a security perspective, the site enforces HTTPS with strong SSL configuration and includes standard security headers. The domain registration is transparent and consistent with the business profile, with no privacy protection masking registrant data. However, the site lacks explicit privacy policy and terms of service pages in the provided content, and no incident response or vulnerability disclosure policies are found, which are areas for improvement. Overall, Blockthrough presents a mature, credible business with a solid technical foundation and good security posture. Strategic recommendations include publishing explicit privacy and security policies, enabling DNSSEC, enhancing accessibility, and establishing a vulnerability disclosure program to further strengthen trust and compliance.

Priority findings

5 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
    • 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

Blockthrough operates in the media and technology sectors, focusing on helping publishers monetize adblock traffic through compliant, user-friendly advertising solutions. Its business model is B2B SaaS, providing technology that integrates with existing ad servers and demand sources. The company targets digital publishers globally, including top-tier media companies, as evidenced by its client logos and case studies. The presence of certifications and partnerships with Google and IAB enhances its competitive positioning. Revenue streams likely include platform fees or revenue share from recovered ad impressions. The company demonstrates growth through extensive client adoption (>13,000 sites) and significant revenue recovery ($175M+). The partnership ecosystem includes SSPs, ad networks, and marketing platforms like HubSpot and Calendly, indicating a well-integrated operational model.

Security posture

The website exhibits a good security maturity level with HTTPS enforced and multiple security headers present, reducing common web vulnerabilities. Use of Cloudflare provides additional bot management and DDoS protection. Cookie consent implementation aligns with GDPR requirements, though the absence of a published privacy policy and incident response contacts represents compliance gaps. No exposed sensitive data or vulnerable libraries were detected in the content. The lack of a vulnerability disclosure policy or security.txt file limits transparency for security researchers. Overall, the security posture is strong but could be improved by formalizing policies and enhancing accessibility compliance.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages linked prominently on the website.
  2. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  3. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance website accessibility features to meet WCAG standards for broader compliance.
  5. Add explicit incident response contact information to improve transparency and trust.

Notes

The website is built on a modern WordPress CMS platform using Elementor for page building, supported by jQuery and various third-party integrations such as HubSpot for marketing automation and Calendly for scheduling. Hosting is provided via Cloudflare, offering CDN and security services. The site uses a cookie consent management tool (CookieYes) with detailed cookie categorization and user controls, indicating a mature approach to privacy compliance. Performance is moderate with responsive design and mobile optimization. SEO is supported by proper meta tags and structured data. Technical risks are minimal, though enabling DNSSEC and improving accessibility would enhance the technical posture further.
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.
