69/100

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

Stuudium operates an e-school platform primarily targeting students, parents, and teachers in Estonia. The website serves as a portal for users to select their school and log in to the platform. The business model is SaaS-based, providing educational institutions with digital tools for school management. The platform appears to have a moderate market position within the Estonian education sector, focusing on usability and accessibility for its target audience. Technically, the website uses standard web technologies including HTML5, CSS3, and JavaScript, with assets hosted on a dedicated CDN domain. The site is basic in design and functionality, with minimal content and limited SEO or accessibility features. Mobile optimization is present but basic. No advanced frameworks or CMS platforms are detected from the provided HTML. From a security perspective, the site uses HTTPS (assumed from external asset URLs), but no explicit security headers or policies are visible. The form disables autocomplete and autocorrect to enhance input security. However, the absence of privacy, cookie, and terms of service policies indicates gaps in compliance with GDPR and other regulations. No contact or incident response information is provided, limiting transparency and trust. Overall, the website is functional but basic, with moderate business credibility but limited privacy and security maturity. Strategic improvements in compliance documentation, security headers, and user trust signals are recommended to enhance the platform's security posture and regulatory adherence.

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

6 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

    • 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

  • Security headers: did not complete in this scan.
  • 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

Stuudium is positioned as a specialized SaaS provider in the education sector, focusing on e-school management solutions. Its competitive advantage lies in serving a niche market of Estonian schools with a dedicated platform for students, parents, and teachers. The business model relies on platform subscriptions or licensing to educational institutions. The target customer segment is clearly defined, and the platform supports user engagement through school selection and login features. Growth indicators are not visible from the provided data, but the presence of a branded CDN and external corporate site suggests an established operation. Partnerships or subsidiaries are not evident. The lack of visible certifications or trust badges may limit market expansion opportunities.

Security posture

The current security posture is basic with HTTPS usage implied but no explicit security headers detected. The site lacks privacy and cookie policies, which are critical for GDPR compliance. No vulnerability disclosure or incident response information is available, indicating limited readiness for security incidents. The form input fields have some security considerations such as disabling autocomplete, but overall security best practices are not fully implemented. The absence of contact information and security policies reduces transparency and user trust. No known vulnerabilities or malware indicators are detected in the provided content. The security score reflects moderate risk with room for significant improvement.

Recommendations

  1. Implement comprehensive privacy and cookie policies to ensure GDPR compliance and user transparency.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Provide clear contact information including security incident response contacts to improve trust and readiness.
  4. Enhance mobile optimization and accessibility features to improve user experience and compliance with accessibility standards.
  5. Regularly audit and update the technical stack and security configurations to mitigate vulnerabilities and maintain platform integrity.

Technical notes

Notes

The website uses a straightforward technical stack with HTML5, CSS3, and JavaScript. External assets are served from a dedicated CDN domain, indicating a separation of static content delivery. The site lacks advanced frameworks or CMS platforms, suggesting a custom or lightweight implementation. Performance is moderate with no explicit indicators of optimization or caching strategies. Mobile responsiveness is basic, and accessibility features are minimal. SEO optimization is limited, with meta tags instructing noindex but follow, which may affect search engine visibility. The form disables autocomplete and autocorrect, which is a minor security and usability consideration. Overall, the technical infrastructure is functional but could benefit from modernization and enhanced security controls.
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.
