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. 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. 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

  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

gridscale GmbH operates in the cloud infrastructure sector, offering IaaS solutions with a focus on flexibility and reliability. The company appears to have a medium-sized presence with a domain age consistent with its founding year of 2014. Their business model revolves around providing cloud resources such as VMs, storage, and backup services. The website content is targeted at business customers and IT professionals, emphasizing rapid provisioning and data protection features. The company maintains a social media presence on Facebook, but no other partner or subsidiary domains were identified. The lack of visible contact information and compliance policies suggests room for improvement in customer engagement and regulatory adherence.

Security posture

The website employs HTTPS, ensuring encrypted communications. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected, which could enhance protection against common web attacks. There is no evidence of a published security policy, incident response plan, or vulnerability disclosure program, which are important for transparency and trust. The absence of DNSSEC reduces DNS security. No vulnerabilities or exposed sensitive data were identified in the provided content. Overall, the security posture is moderate but could benefit from implementing best practices and publishing relevant security documentation.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
  3. Enable DNSSEC for the domain to improve DNS security.
  4. Publish a security policy and incident response information to increase transparency and trust.
  5. Provide clear contact information including emails and phone numbers for customer and security incident reporting.

Technical notes

Notes

The website is built on WordPress CMS using the Yoast SEO Premium plugin and Bootstrap 4 framework, indicating a modern and SEO-optimized platform. The site is mobile responsive and has good navigation clarity. Performance is moderate based on the complexity of the HTML and CSS observed. No advanced hosting provider information was detected. The absence of advanced security headers and DNSSEC suggests technical improvements are possible. The site does not appear to use extensive third-party analytics or tracking services, indicating minimal user tracking. Overall, the technical infrastructure supports the business needs but can be enhanced for security and compliance.
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.
