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

7 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 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';…

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 · found on this site
  • 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.

Add-on

Leaked records that mention datev.at, from OffSeq Breach.

No leaked records found

Breach holds no records for datev.at right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

DATEV operates in the technology sector, focusing on accounting and tax software solutions for the German-speaking market, particularly Austria. The business model revolves around software licensing, cloud services, and consulting. The website targets tax advisors and small to medium enterprises, offering tailored packages and solutions to support digital transformation and compliance. The company maintains a strong market position with a comprehensive product portfolio and a professional service ecosystem. Partnerships with major platforms like LinkedIn and Facebook are evident through tracking pixels, supporting marketing and outreach efforts. The absence of explicit phone or email contacts on the main site suggests a preference for controlled communication channels, likely via contact forms and service portals.

Security posture

The website enforces HTTPS and employs a cookie consent banner with detailed categories, demonstrating compliance with privacy regulations. Security best practices include the use of a honeypot plugin to mitigate spam and no visible exposure of sensitive data. However, the site lacks explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are recommended to enhance protection against common web attacks. No vulnerability disclosures or incident response policies are published, which could be improved to increase transparency and readiness. Overall, the security posture is good but could benefit from additional hardening and formalized security communication.

Recommendations

  1. Implement and enforce Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to strengthen web security.
  2. Publish a security policy and incident response contact information to improve transparency and preparedness.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly audit and update all plugins and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress 6.6.2, utilizing popular JavaScript libraries such as jQuery and Owl Carousel for interactive elements. The presence of Yoast SEO structured data indicates attention to search engine optimization. The site uses lazy loading for images and responsive design techniques, contributing to good performance and mobile optimization. Hosting details are not explicitly disclosed, but the site uses HTTPS with a valid SSL certificate. The technical implementation is modern and stable, though some security headers are missing. Performance is moderate, with opportunities for optimization in loading speed and accessibility compliance.
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.
