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. 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

  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"

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

TESSEA operates as a niche social enterprise network in the Czech Republic, targeting social entrepreneurs and related stakeholders. Its business model revolves around membership, networking, advocacy, and promotion of social economy initiatives. The organization leverages partnerships and regional representation to maintain a national footprint. The website content and metadata emphasize social entrepreneurship, indicating a focused market segment. The absence of direct contact details suggests a controlled communication channel, likely to manage inquiries efficiently. The use of Joomla and various extensions indicates a preference for established open-source technologies. The domain age and WHOIS data support the legitimacy and stability of the organization. No direct revenue streams or commercial activities are evident from the website content.

Security posture

The website enforces HTTPS and uses Google reCAPTCHA v3 to mitigate automated abuse. Cookie consent is implemented with GDPR compliance, including anonymized IP tracking in Google Analytics. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security posture. The use of an outdated Bootstrap version (2.3.2) may expose the site to known vulnerabilities if not properly patched. No exposed sensitive data or credentials were detected in the HTML content. Incident response and security policy documentation are not publicly available, which could hinder rapid response to security incidents. Overall, the site demonstrates a moderate security maturity level with room for improvement in headers and framework updates.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to enhance protection against common web attacks.
  2. Upgrade Bootstrap and other third-party libraries to their latest stable versions to mitigate known vulnerabilities.
  3. Publish explicit security policy and incident response information to improve transparency and preparedness.
  4. Consider adding direct verified contact emails and phone numbers for improved business credibility and user trust.
  5. Regularly audit Joomla CMS and installed extensions for security patches and updates to maintain a secure environment.

Technical notes

Notes

The website is built on Joomla CMS with Bootstrap 2.3.2 framework and uses jQuery along with several Joomla extensions such as SP Page Builder and JCEMediaBox. Google Analytics with IP anonymization and Google reCAPTCHA v3 are integrated for analytics and security. The site loads multiple CSS and JS assets, including FontAwesome icons and Google Fonts. Performance is moderate with responsive design and mobile optimization evident. Accessibility features are basic but present. SEO optimization is good with proper meta tags and Open Graph data. Hosting is likely provided by Active24, consistent with the domain registrar. The technical stack is stable but could benefit from modernization, especially updating legacy frameworks and adding security headers.
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.
