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

3 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • 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

  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

The company occupies a niche in anti-detect browser technology, providing solutions for multi-accounting and digital fingerprint protection. Their competitive advantage lies in unique technologies for browser fingerprinting, proxy management, and automation. Revenue streams include subscriptions, add-ons like the Cookies Converter, and affiliate commissions. The target customers are professionals in traffic arbitrage, digital agencies, affiliate marketing, e-commerce, online betting, and social marketing. The company maintains active social media channels and a partner ecosystem. Growth indicators include recent domain registration (2020) and continuous product updates. Strategic observations suggest focusing on enhancing privacy compliance and publishing security policies to strengthen market trust.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, multiple security headers, and secure cookie attributes. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program indicates gaps in transparency and readiness. GDPR compliance is supported by a comprehensive privacy policy but lacks explicit cookie consent mechanisms. The company should consider publishing security documentation and implementing consent banners to improve compliance and user trust. Incident response contact channels are not provided, which could hinder timely communication during security events.

Recommendations

  1. Implement a cookie consent mechanism to comply with GDPR and enhance user privacy transparency.
  2. Publish a detailed security policy and incident response plan accessible from the website.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve usability for all users.
  5. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.

Technical notes

Notes

The website is built using the Astro framework with modern JavaScript modules and Headless UI components, ensuring a fast and responsive user experience. Hosting is via Cloudflare DNS and CDN, providing performance and security benefits. Analytics integration includes Google Tag Manager, Yandex Metrika, and TikTok Pixel, enabling comprehensive user behavior tracking. The site is mobile-optimized with good SEO practices and clear navigation. No CMS was detected, indicating a custom or static site approach. Technical risks are minimal, but the lack of DNSSEC and cookie consent mechanisms are areas for improvement. Overall, the technical infrastructure supports the business goals effectively with room for enhanced security and privacy features.
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.
