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

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 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

    • 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

Surfshark operates a subscription-based business model focused on delivering privacy and cybersecurity services globally. Its market position is reinforced by multiple industry awards and a broad product portfolio that addresses various aspects of online security and privacy. The company leverages partnerships such as Incogni for data removal services and promotes affiliate programs to expand reach. Target customers include privacy-conscious consumers and business teams. The company shows growth potential through continuous product innovation and strong social media engagement. The domain age and registration details align with a legitimate and stable business operation. Surfshark's ecosystem includes complementary services like Surfshark Search and Surfshark Alert, enhancing its competitive advantage.

Security posture

Surfshark demonstrates a mature security posture with HTTPS enforced site-wide, comprehensive security headers, and a no-logs policy supported by RAM-only servers to protect user data. The domain is protected against unauthorized transfers, and the company maintains transparency through published trust centers and privacy policies. However, the absence of DNSSEC and a publicly available security.txt file limits the completeness of its security framework. Incident response contact channels are not explicitly provided, which could hinder rapid vulnerability reporting. No critical vulnerabilities or exposed sensitive data were detected in the analysis. Overall, Surfshark maintains strong security practices appropriate for its industry and customer expectations.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide explicit incident response contact information (e.g., security@ or abuse@ emails).
  4. Consider publishing Data Protection Officer contact details to improve GDPR transparency.
  5. Regularly audit and update third-party scripts to minimize potential security risks.

Technical notes

Notes

The website is built on a modern React and Next.js framework, ensuring server-side rendering and good SEO performance. It uses advanced analytics tools like Snowplow and Google Tag Manager for data collection and marketing insights. Hosting appears to be on a reputable provider (Hetzner Online GmbH), with fast loading times and excellent mobile responsiveness. The site includes accessibility features and comprehensive meta tags for SEO. Technical debt is minimal, but enabling DNSSEC and improving incident response mechanisms would further strengthen the infrastructure. The use of multiple external domains for affiliate and partner services is well managed without suspicious links.
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.
