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

4 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 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 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

  3. 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.

Business context

Business profile

Studo GmbH operates in the education technology sector, targeting universities, students, and administrative bodies. Their business model combines B2B and B2C SaaS offerings, providing apps and digital services that streamline communication, administration, and student engagement. The company enjoys a strong market position in Austria and surrounding countries, with over 50 institutional partnerships and a large user base. Their competitive advantages include comprehensive service offerings, strong certifications, and a focus on accessibility and data protection. Revenue streams likely include licensing, white-label solutions, and service contracts. Growth indicators include continuous product development, awards, and EU funding support. The partnership ecosystem includes European research and innovation bodies and regional funding agencies, supporting strategic expansion and innovation.

Security posture

Studo GmbH demonstrates a mature security posture with enforced HTTPS, TÜV SÜD certification validating software quality and GDPR compliance, and annual accessibility and security audits. The website uses secure forms with explicit GDPR consent, and no exposed sensitive data or vulnerable libraries were detected. However, the absence of DNSSEC and a published security.txt file indicates room for improvement in DNS security and vulnerability disclosure transparency. Incident response contact information is not explicitly provided, which could hinder rapid communication in case of security events. Overall, the company shows strong data protection practices aligned with GDPR and IT-Grundschutz standards, but should enhance transparency and DNS security to further strengthen their security culture.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Publish a security.txt file on the website to provide clear vulnerability disclosure and incident response contacts.
  3. Implement a visible cookie consent banner to comply fully with GDPR cookie consent requirements.
  4. Add security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Content-Type-Options to enhance web security.
  5. Provide explicit incident response contact information (e.g., security@ or abuse@ email) to improve communication channels for security issues.

Technical notes

Notes

The website is built with modern web standards including HTML5, CSS3, and JavaScript, with assets optimized using WebP images for performance. It leverages Cloudflare for DNS and CDN services, enhancing availability and speed. Analytics are handled via Piwik PRO, a privacy-focused platform. The site is mobile responsive and accessible, following WCAG and EU accessibility directives. No CMS or specific frameworks were detected, suggesting a custom or lightweight implementation. Performance is fast with preloaded stylesheets and deferred scripts. Technical risks include lack of DNSSEC and missing security headers, which are recommended for mitigation. Overall, the technical infrastructure supports a professional and scalable digital presence.
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.
