Risk levelHigh

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

ERA21 is a Czech media company specializing in architecture and design content, publishing a magazine and providing online articles, news, and event information. The company targets architects, designers, and industry professionals, operating primarily in the Czech Republic with a small-sized business model focused on media publishing and advertising revenue. The website is professionally designed with consistent branding and clear contact information, supported by official Czech cultural institutions. Technically, the site uses legacy JavaScript libraries such as jQuery 1.11 and common UI plugins, with moderate performance and good mobile optimization. Security posture is adequate with HTTPS enforced and cookie consent implemented, but lacks advanced security headers and a visible privacy policy. WHOIS data is unavailable, which slightly reduces trust but the business presence and content quality support legitimacy. Overall, the site is functional, professional, and trustworthy with room for improvement in privacy and security transparency.

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

9 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

  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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

ERA21 holds a niche position in the Czech architecture media market with a 25-year history. Its competitive advantage lies in specialized content and official support from cultural and governmental bodies. The business model relies on subscriptions and advertising, with partnerships evident through linked domains and sponsors. The target customer segment includes architecture professionals and enthusiasts. Growth indicators include active event promotion and digital content updates. The company maintains a professional online presence but could enhance transparency and compliance to strengthen market trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent mechanisms in place. However, it lacks critical security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web attacks. No incident response or vulnerability disclosure information is provided, limiting readiness for security events. The absence of a privacy policy page and security.txt file indicates gaps in compliance and transparency. No vulnerable libraries or exposed sensitive data were detected in the HTML content. Overall, the security posture is adequate but could benefit from improvements in headers, policies, and incident readiness.

Recommendations

  1. Implement and publish a comprehensive privacy policy page detailing GDPR compliance and data handling practices.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web vulnerabilities.
  3. Create and maintain a security.txt file to facilitate vulnerability disclosure and improve incident response communication.
  4. Update JavaScript libraries to current versions to reduce risk of known vulnerabilities.
  5. Enhance website accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website uses a traditional tech stack centered on jQuery 1.11 and associated UI plugins such as jCarousel and Nivo Slider. While functional, these libraries are outdated and may pose security risks if not regularly updated. The site loads external resources from reputable CDNs including Google Fonts and Font Awesome. Performance is moderate with no explicit optimization indicators. Mobile responsiveness is good, supported by viewport meta tags and responsive CSS. SEO is basic with minimal meta description and keywords. No CMS or hosting provider information is discernible from the HTML. Technical debt is present due to legacy libraries and lack of modern security headers, suggesting opportunities for modernization and improved security posture.
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.
