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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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. 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';…

  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 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

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 holds a niche position in the energy storage sector in the Czech Republic, leveraging its long operational history and substantial storage capacity. Their business model focuses on providing storage services and capacity auctions to cross-border clients. The website content and structure suggest a focus on transparency and compliance, with downloadable official documents and clear navigation. The absence of direct contact emails or phone numbers on the site may indicate a preference for controlled communication channels, possibly via customer zones or partner portals. The company appears to maintain a moderate-sized team and emphasizes corporate responsibility and environmental respect.

Security posture

SPP Storage demonstrates a mature security posture with enforced HTTPS, cookie consent mechanisms, and no visible exposure of sensitive data. However, the lack of explicit security headers such as Content Security Policy or HSTS is a minor gap. No incident response contacts or vulnerability disclosure policies are published, which could be improved to enhance trust and readiness. The site does not use any known vulnerable libraries and employs standard Drupal security practices. Overall, the security posture is good but could benefit from enhanced transparency and additional security controls.

Recommendations

  1. Implement and publish a security.txt file or vulnerability disclosure policy to facilitate responsible reporting.
  2. Add HTTP security headers such as Content Security Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide explicit incident response contact information to improve transparency and trust.
  4. Consider adding verified company contact emails and phone numbers on the website for easier communication.
  5. Regularly review and update cookie and privacy policies to maintain GDPR compliance and user trust.

Technical notes

Notes

The website is built on Drupal 10, leveraging modern CSS normalization and JavaScript libraries like jQuery and Swiper.js for UI components. The site is hosted with a registrar Active24, using their name servers. Performance is moderate with good mobile responsiveness and accessibility features. SEO is supported by proper meta tags and language alternates. The site uses a cookie compliance module for EU regulations. No major technical debt or outdated components were detected. Opportunities exist to enhance security headers and improve incident response readiness.
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.
