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

deltacity is an independent digital service provider based in Germany specializing in the development of sophisticated digital platforms across digital health, commerce, and content management sectors. The company offers comprehensive services including strategic consulting, creative conception, innovative software development, and technical implementation. Their website reflects a professional and consistent brand presence with clear service offerings and active recruitment efforts, indicating a medium-sized enterprise with a solid market position in the technology sector. Technically, the website is built on Drupal 10 CMS, employs Matomo for analytics with user consent management via CookieFirst, and integrates multimedia content through Vimeo. The site is mobile-optimized with good SEO and accessibility features, although some security headers are not explicitly detected. HTTPS is enforced, and privacy policies are comprehensive and GDPR compliant. From a security perspective, the site demonstrates good practices such as encrypted connections and cookie consent but lacks visible incident response contacts or vulnerability disclosure mechanisms. The absence of WHOIS data for the domain raises concerns about domain registration legitimacy, although the website content and branding suggest a legitimate business. This discrepancy warrants further investigation to confirm domain ownership and registration status. Overall, deltacity presents a trustworthy and professional digital agency with a mature digital infrastructure. Strategic recommendations include enhancing security headers, publishing explicit security policies, and resolving WHOIS inconsistencies to strengthen trust and compliance.

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. 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

  2. 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

deltacity operates as a specialized digital agency focusing on digital health, commerce, and content management platforms. Their business model centers on providing end-to-end digital strategy and solution services, targeting businesses requiring sophisticated digital transformation. The company maintains a competitive advantage through its expertise in digital health projects and a strong presence in the German market. Active job listings indicate growth and investment in talent acquisition. The partnership ecosystem includes external analytics and consent management providers, but no direct partner or subsidiary domains were identified. Revenue streams likely derive from consulting, software development, and platform maintenance contracts. The company’s clear branding and professional content support a high level of business credibility.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism aligned with GDPR requirements, reflecting a good baseline security posture. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection reduces defense-in-depth effectiveness. No explicit security policy or incident response contact information is published, which may hinder timely vulnerability reporting and incident management. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of Matomo analytics with consent indicates privacy-conscious tracking. Overall, the security maturity is moderate with room for improvement in header implementation and incident response transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a clear security policy and provide dedicated incident response contact channels such as security@ or abuse@ email addresses.
  3. Conduct regular audits of third-party scripts and dependencies to identify and mitigate potential vulnerabilities.
  4. Resolve WHOIS data inconsistencies by ensuring domain registration information is accurate and publicly available to improve trustworthiness.
  5. Enhance accessibility features and conduct usability testing to improve user experience for all visitors.

Technical notes

Notes

The website is built on Drupal 10 CMS, a modern and widely supported content management system, indicating a solid technical foundation. Integration with Vimeo for video content and Matomo for analytics shows a balanced use of third-party services with privacy considerations. The CookieFirst consent management system is properly implemented, supporting GDPR compliance. Performance is moderate with responsive design and mobile optimization evident. However, the lack of detected security headers and incomplete WHOIS data suggest areas for technical improvement. Hosting provider details are not explicitly identified from the content. Overall, the technical infrastructure supports the business needs but would benefit from enhanced security configurations and domain registration transparency.
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.
