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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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.

Business context

Business profile

STRATO holds a strong market position as a large European hosting provider with a diversified product portfolio that includes domains, hosting, servers, cloud storage, and marketing services. Its competitive advantages include ISO 27001 certification, green energy commitment, and a 30-day money-back guarantee. The business model is subscription-based with flexible packages and a focus on customer satisfaction. The company operates multiple subsidiaries across Europe, enhancing its regional presence. Partnerships such as with Cronon GmbH expand its ecosystem. The website content and structure indicate a focus on SMBs and professionals seeking reliable hosting and online business solutions. Growth indicators include marketing tools and online shop offerings, positioning STRATO well in the digital services market.

Security posture

STRATO demonstrates a mature security posture with ISO 27001 certification and data centers located in Germany, ensuring compliance with EU data protection standards. The website enforces HTTPS and provides a comprehensive cookie consent mechanism aligned with GDPR requirements. However, explicit security headers like Content Security Policy and HSTS are not visibly configured, and no public vulnerability disclosure or incident response policies are found. No exposed sensitive data or vulnerabilities were detected in the website content. The absence of direct security contact information limits incident reporting transparency. Overall, the security maturity is high but could benefit from enhanced public security documentation and headers.

Recommendations

  1. Implement and publish comprehensive security headers such as CSP, HSTS, and X-Frame-Options to enhance browser security.
  2. Establish and publicly disclose a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  3. Provide clear and accessible contact information for security incidents and data protection officer details.
  4. Regularly audit and update third-party scripts and tracking tools to minimize privacy risks and ensure compliance.
  5. Enhance transparency around data retention policies and incident response procedures to build customer trust.

Notes

The website is built on a modern technology stack including Strapi CMS and JavaScript frameworks, with integration of Google Tag Manager and Jentis for consent management. It is hosted likely on STRATO's own infrastructure or IONOS services, ensuring good performance and reliability. The site is mobile-optimized with responsive design and accessibility features. SEO best practices are followed with proper meta tags and Open Graph data. The technical implementation is robust with no visible technical debt or performance bottlenecks. Opportunities exist to improve security headers and public security documentation to further strengthen the technical posture.
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.
