Medium risk. 3 critical or high findings in Security headers and SSL/TLS.

Security score

73/100

Risk levelMedium

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

Datarun is a Czech technology company specializing in data processing and automation solutions, targeting business clients. The website is built using modern web technologies including React and Next.js, hosted behind Cloudflare, and incorporates cookie consent mechanisms via Cookiebot. The site demonstrates a moderate level of digital maturity with good design quality and mobile optimization. Security posture is solid with HTTPS enforced and standard security headers present, though the absence of a privacy policy and contact information reduces compliance and trust levels. The domain WHOIS data is unavailable, likely due to privacy protection, which slightly impacts legitimacy assessment. Overall, the website is professional and functional but would benefit from enhanced transparency and compliance documentation.

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 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. 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

The company operates in the technology sector focusing on data and automation services, likely serving small to medium-sized enterprises. The business model appears to be B2B with key services including data processing and integration. The website's use of multiple third-party advertising and analytics services indicates an active marketing approach. However, the lack of explicit business contact details and corporate information limits full business intelligence insights. No partnerships or subsidiaries are explicitly identified from the website content.

Security posture

The website enforces HTTPS and employs security headers such as HSTS, X-Content-Type-Options, and Content-Security-Policy, reflecting good security hygiene. Cookie consent is actively managed, supporting GDPR compliance efforts. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a published privacy policy and terms of service represents a compliance gap. Incident response and security policy information are not publicly available, which could hinder trust and preparedness. Regular audits of third-party scripts and enhanced transparency are recommended.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Provide clear and accessible contact information including company emails and phone numbers.
  3. Conduct regular security audits of third-party scripts and dependencies to mitigate vulnerabilities.
  4. Enhance website accessibility features to improve inclusivity and compliance with standards.
  5. Consider publishing security policies and incident response procedures to demonstrate security maturity.

Technical notes

Notes

The website leverages a modern React and Next.js stack, ensuring good performance and mobile responsiveness. Hosting via Cloudflare provides CDN and security benefits. The site uses Cookiebot for cookie management and Google Tag Manager for analytics integration. While performance is moderate, there is room for improvement in SEO and accessibility. The absence of a CMS is noted, suggesting a custom or static site approach. Technical debt appears low but could increase without ongoing maintenance of third-party integrations.
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.
