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

Adsterra is a well-established online advertising network founded in 2012, providing cost-effective high-quality traffic solutions for advertisers and monetization opportunities for publishers. The company positions itself as a top player in the advertising technology sector, targeting advertisers and publishers globally. The website reflects a professional and modern design, leveraging popular technologies such as Bootstrap and multiple analytics platforms to optimize user experience and marketing effectiveness. The technical infrastructure includes robust domain registration with Amazon Registrar and DNS services via Cloudflare, although DNSSEC is not enabled, representing a minor security gap. Security posture is generally good with HTTPS enforced and domain status protections in place, but explicit security policies and headers are not evident in the content. Privacy compliance is partially addressed through a cookie consent mechanism, but no explicit privacy or terms of service policies were found in the analyzed content. Overall, the website demonstrates moderate to good digital maturity and business credibility, with extensive user tracking and advertising technologies integrated. No adult or explicit content was detected, making the site safe for general audiences.

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

2 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 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 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

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

Adsterra operates in the technology sector as an advertising network, serving both advertisers seeking quality traffic and publishers looking to monetize their inventory. The business model revolves around facilitating online ad placements and traffic monetization, likely generating revenue through ad impressions, clicks, and conversions. The company has maintained domain registration consistency since 2012, indicating stable operations. The presence of multiple third-party tracking and marketing tools suggests a mature marketing ecosystem aimed at optimizing campaign performance and user engagement. However, the lack of visible contact information and formal policies may limit transparency. The company’s market positioning as a top advertising network is supported by its branding and service offerings, although further details on partnerships or subsidiaries were not found. The website’s content and design quality support a medium-sized enterprise profile with a focus on technology and digital advertising.

Security posture

The security posture of the website is generally sound with HTTPS enabled and domain registration protections such as clientDeleteProhibited and clientTransferProhibited statuses active. However, the absence of DNSSEC reduces DNS security robustness. The website includes multiple third-party scripts for analytics and advertising, which increases the attack surface and requires careful management to avoid vulnerabilities. No explicit security headers or policies were detected in the HTML content, and no incident response or security contact information is provided, which could be improved to enhance trust and readiness. The cookie consent mechanism indicates some level of privacy compliance, but the lack of a visible privacy policy and terms of service is a compliance gap. Overall, the site demonstrates moderate security maturity but would benefit from enhanced security documentation and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish comprehensive privacy policy and terms of service pages to improve compliance and transparency.
  3. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide explicit security policy and incident response contact information to enhance trust and preparedness.
  5. Review and audit third-party scripts regularly to minimize security risks and ensure compliance with privacy regulations.

Technical notes

Notes

The website uses a modern technology stack including Bootstrap 5 for responsive design, multiple analytics platforms (Amplitude, Yandex Metrica, Google Analytics), and marketing tools such as Survicate and Cookiebot. The domain is registered with Amazon Registrar and uses Cloudflare DNS services, indicating reliable hosting infrastructure. Performance is moderate with preloading and asynchronous loading of scripts to optimize speed. Mobile optimization is good due to responsive design frameworks. Accessibility features are basic but present. SEO optimization is supported by proper meta tags and Open Graph data. However, the absence of CMS identification suggests a custom or proprietary platform. The technical implementation is solid but could be enhanced with improved security headers and privacy documentation.
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.
