Risk levelMedium

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

gridscale GmbH is a German technology company specializing in cloud infrastructure services. Their website presents a portfolio of cloud solutions including virtual machine provisioning, integrated backups, live snapshots, and features aimed at flexibility and reliability. The company targets businesses and IT professionals seeking scalable cloud infrastructure. The website is built on WordPress using the Astra theme and Yoast SEO plugin, indicating a modern and SEO-optimized platform. Performance and mobile optimization are good, though accessibility is basic. Security posture is adequate with HTTPS enabled but lacks advanced security headers and published security policies. Privacy and cookie policies are absent, which is a compliance gap. The domain registration is consistent with the business claims, showing legitimacy and a mature presence since 2014.

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 data protection. Their business model revolves around providing scalable cloud resources suitable for various workloads. The company appears medium-sized, established in 2014, and based in Germany. The website content is professional and consistent with their market positioning. No explicit partnerships or subsidiaries are identified from the website content. The company leverages standard WordPress technologies and SEO tools to maintain digital presence. Lack of visible contact details and compliance documentation may limit trust for some customers.

Security posture

The website employs HTTPS, ensuring encrypted communications. However, no security headers such as Content-Security-Policy or Strict-Transport-Security were detected, which could enhance protection against common web attacks. There is no published security policy or incident response information, which are important for transparency and readiness. No vulnerabilities or exposed sensitive data were found in the content. The absence of privacy and cookie policies indicates potential GDPR compliance gaps. Overall, the security posture is moderate but could be improved by implementing recommended headers, publishing security documentation, and adding privacy compliance mechanisms.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish a comprehensive privacy policy and cookie consent mechanism to comply with GDPR and enhance user trust.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to strengthen web security.
  4. Publish a security policy and incident response plan with contact channels for reporting security issues.
  5. Include clear contact information such as company emails and phone numbers to improve business credibility and user support.

Technical notes

Notes

The website is built on WordPress CMS with the Astra theme and uses the Yoast SEO Premium plugin for SEO optimization. The front-end uses Bootstrap 4 framework for responsive design. DNS is managed via dnsimple.com nameservers, but DNSSEC is not enabled. The site is served over HTTPS with a valid SSL certificate. Performance is moderate with good mobile optimization. Accessibility features are basic and could be enhanced. No analytics or tracking scripts were detected, indicating minimal user tracking. The technical stack is modern and suitable for the business needs but could benefit from improved security configurations and accessibility enhancements.
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.
