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

Memento Historia is a Czech-language online magazine dedicated to ancient and medieval history, providing educational articles and multimedia content such as podcasts on YouTube. The website targets history enthusiasts and the general public interested in historical topics, operating primarily as a content publisher monetized through advertising networks like Seznam SSP and Google Ads. The site demonstrates a consistent and professional brand presentation with a good quality of content and user experience. Technically, the website employs modern frontend technologies including Bootstrap, jQuery, Google Fonts, and integrates analytics and advertising scripts from Google and Seznam. The site is mobile optimized and performs moderately well, though accessibility features are basic. Security posture is adequate with HTTPS enabled but lacks important security headers, and no explicit privacy or cookie policies are found, though a cookie consent mechanism is present. The WHOIS data for the domain is unavailable, which limits the ability to verify domain registration legitimacy and age. Despite this, the website appears professionally maintained with active content updates and social media presence. No critical security vulnerabilities or adult content were detected, and the site is safe for general audiences. Overall, Memento Historia is a niche media site with solid content and technical foundation but would benefit from improved transparency in privacy policies, enhanced security headers, and WHOIS data availability to strengthen trust and compliance.

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

13 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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"

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 · found on this site
  • 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

Memento Historia occupies a niche position in the Czech media market as a specialized historical content provider. Its competitive advantage lies in focused, well-presented historical articles and multimedia content targeting history enthusiasts. The business model relies on advertising revenue through established ad networks. The presence of social media channels supports audience engagement and content distribution. Growth potential exists through expanded multimedia offerings and improved compliance and security practices. The lack of visible company registration or detailed business information suggests a small-scale operation primarily focused on content publishing rather than commercial services.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. The use of multiple third-party scripts for analytics and advertising introduces potential risk vectors that require regular auditing. No incident response or security policy information is provided, indicating limited formal security governance. Compliance with GDPR is partial, with cookie consent present but no detailed privacy policy. Overall, the security posture is functional but could be significantly improved with standard best practices and transparency.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Add essential security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against web vulnerabilities.
  3. Conduct regular security audits of third-party scripts and dependencies to mitigate risks from external content.
  4. Improve accessibility features to broaden audience reach and comply with accessibility standards.
  5. Seek to clarify domain registration details or use WHOIS privacy responsibly to enhance domain legitimacy and trust.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap for responsive design, Google Fonts for typography, and jQuery for scripting. Analytics and advertising are integrated via Google Analytics, Google Tag Manager, and Seznam SSP scripts. The site loads asynchronously for performance optimization and is mobile-friendly. However, no CMS or backend platform is explicitly detected. Performance is moderate with room for improvement in accessibility and SEO. The lack of security headers and missing privacy documentation represent technical debt and compliance gaps. Hosting provider details are not discernible from the content. Overall, the technical infrastructure supports the business needs but requires enhancements for security 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.
