MainPost is a well-established regional news media company serving Würzburg, Schweinfurt, Franken, Bayern, and broader Germany. It offers a comprehensive news platform with local sports, economy, culture, and event information. The company operates multiple subsidiary services including digital newspapers, advertising booking, job listings, and special event platforms, positioning itself as a key regional media player. Technically, the website employs modern JavaScript frameworks, consent management via Usercentrics, and integrates advertising and marketing tools such as Stroeer and Taboola. The site is mobile-optimized and uses structured data for SEO enhancement.

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

5 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 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. 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 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
  • 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

MainPost holds a strong market position as a regional media leader with diversified revenue streams including advertising, subscriptions, and event services. Its business model focuses on digital and print media integration, leveraging local market knowledge and community engagement. The presence of multiple branded subdomains indicates a broad service ecosystem. The company targets a general audience interested in regional news and culture. Partnerships with advertising networks and marketing platforms enhance monetization. Growth potential lies in digital transformation and expanding digital subscriptions. The lack of explicit registrant WHOIS data slightly limits full business verification but does not detract from evident operational maturity.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of a consent management platform for privacy compliance, and no visible exposure of sensitive data. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options is a gap. No vulnerability disclosure or incident response contacts are published, which could hinder rapid response to security incidents. The integration of multiple third-party scripts and ad networks introduces potential risk vectors that require ongoing monitoring. Overall, the security maturity is good but can be enhanced by adopting additional security best practices and transparency measures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  3. Publish a security policy and incident response contact information, including a security.txt file to facilitate vulnerability reporting.
  4. Regularly audit third-party scripts and advertising integrations to minimize security risks and ensure compliance.
  5. Enhance accessibility features and provide clear contact information including verified company emails and phone numbers.

Technical notes

Notes

The website uses a modern JavaScript-based front end with asynchronous script loading for performance. It integrates multiple third-party services for consent management (Usercentrics), paywall/subscription management (Tinypass/Piano), advertising (Stroeer, Taboola), and push notifications (Cleverpush). Hosting appears to be managed by iwelt-ag.net, a German hosting provider. The site is mobile responsive and uses structured data (JSON-LD) extensively for SEO and content clarity. Performance is moderate with some deferred script loading. Accessibility is basic but could be improved. No CMS is explicitly detected. The technical stack is robust for a regional media site but could benefit from enhanced security headers and performance optimizations.
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.
