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

9 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 positions itself as an experienced IT service provider with a focus on web and cloud technologies. Its business model revolves around providing tailored digital solutions to diverse clients. The website content is consistent and professional, though lacking direct contact emails or phone numbers, relying solely on a contact form. No social media presence or partner domains are linked, indicating a focused but limited digital footprint. The absence of privacy and cookie policies may affect compliance and trust. The company appears stable with a domain age consistent with its stated experience, but the lack of advanced marketing or analytics tools suggests a modest digital maturity level.

Security posture

Security posture is basic with no HTTPS/SSL data explicitly provided but assumed given modern web standards. The domain has clientTransferProhibited status but lacks DNSSEC and security headers such as CSP or HSTS. No privacy or cookie policies are published, and no incident response or vulnerability disclosure information is available. The contact form collects personal data but no visible security measures or data protection statements are present. Overall, the site shows minimal security best practices and lacks transparency on data protection, representing a moderate risk level.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Enable DNSSEC and add security headers (CSP, HSTS, X-Frame-Options) to enhance domain and site security.
  3. Provide direct company contact emails and phone numbers clearly labeled for better communication and credibility.
  4. Add incident response and vulnerability disclosure information to demonstrate security readiness.
  5. Conduct a security audit to identify and remediate potential vulnerabilities and improve overall security posture.

Technical notes

Notes

The website is built using Bootstrap 5.1 and Mobirise CSS, with Google Fonts integration and JavaScript for interactivity. It uses a contact form powered by Formoid for data collection. The site is mobile responsive and has a moderate performance profile. No CMS or backend technologies are detected from the HTML content. Hosting is managed through IONOS SE with DNS servers at iaasdns.com. SEO optimization is basic with meta tags present but no advanced structured data or Open Graph tags. Accessibility features are minimal but present. The site lacks advanced analytics or marketing tools, indicating room for technical modernization.
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.
