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

Diecéze ostravsko-opavská operates as the official diocesan organization for the Ostravsko-Opavská region in the Czech Republic, providing religious, pastoral, educational, and community services. The website serves as a comprehensive information portal for parishioners, clergy, and the general public interested in diocesan activities, events, and organizational structure. It maintains a consistent brand presence and offers multiple communication channels including social media and direct contact information. Technically, the website is built on WordPress with a modern tech stack including Yoast SEO, WPBakery Page Builder, and several plugins enhancing user experience and content management. Hosting is provided by cesky-hosting.eu, and the site is optimized for mobile devices with good SEO practices. Performance is moderate, with room for improvement in accessibility and security headers. From a security perspective, the site enforces HTTPS and uses nonce tokens for AJAX requests, indicating a baseline security posture. However, it lacks explicit security headers and a public security policy or incident response information. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is partially met with a comprehensive privacy policy but lacks a cookie consent mechanism. Overall, the website is trustworthy, professional, and well-maintained, suitable for its non-profit religious mission. Strategic improvements in privacy compliance and security hardening would enhance its risk posture and user trust.

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

8 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

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 diocesan website holds a strong market position as the official digital presence of the Ostravsko-Opavská diocese, targeting religious communities and stakeholders in the Czech Republic. Its business model is non-profit, focusing on community engagement, information dissemination, and spiritual services. Revenue streams are likely supported by donations and church funding rather than commercial activities. The site demonstrates a well-established partnership ecosystem with related diocesan and religious entities, including SharePoint intranet and cultural initiatives like Varhany pro Ostravu. Growth indicators include active event calendars, multimedia content, and educational offerings. The organization benefits from a clear governance structure and transparent communication channels.

Security posture

The website exhibits a moderate to good security maturity level. HTTPS is properly configured, and nonce tokens are used for form submissions, reducing CSRF risks. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options limits protection against clickjacking and content injection attacks. No public vulnerability disclosure or incident response contacts are provided, which could hinder timely reporting and mitigation of security incidents. Data protection practices align with GDPR through a comprehensive privacy policy, but the lack of cookie consent mechanisms is a compliance gap. Overall, the site shows awareness of security best practices but would benefit from enhanced policies and technical controls.

Recommendations

  1. Implement a cookie consent banner to comply with GDPR and enhance user privacy transparency.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen defense against common web attacks.
  3. Publish a security policy and incident response contact information to facilitate vulnerability reporting and improve trust.
  4. Enhance accessibility features to meet WCAG standards and improve usability for all users.
  5. Regularly audit and update all plugins and themes to mitigate risks from outdated software.

Notes

The website is built on a stable WordPress platform using the Salient theme and popular plugins such as Yoast SEO and WPBakery Page Builder. It leverages jQuery and Flickity for interactive elements. Hosting is provided by cesky-hosting.eu, with DNS configured accordingly. The site is mobile-optimized and includes structured data (JSON-LD) for SEO enhancement. Performance is moderate, with potential improvements in loading speed and accessibility. No critical technical debt or deprecated technologies were detected. The site lacks advanced security headers and cookie consent mechanisms, which are recommended for modernization and 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.
