Risk levelMedium

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

Tomáš Kalina's website is a personal portfolio and blog primarily targeting a general audience interested in his work or content. The site is built on WordPress using a premium theme and hosted on a Czech hosting provider. The technical infrastructure is modern and includes HTTPS with a valid SSL certificate, but lacks advanced security headers and DNSSEC. Privacy compliance is minimal, with no privacy policy or terms of service found, though a cookie consent mechanism is present. Contact information is limited to a contact form without explicit email or phone details. Overall, the site is professionally designed with good user experience but could improve 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

7 findings rated critical or high. Fix these first.

  1. 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

  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"

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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.

Add-on

Leaked records that mention tomaskalina.com, from OffSeq Breach.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The website serves as a personal branding platform for Tomáš Kalina, with no clear commercial business model or extensive services offered. It targets a niche audience likely familiar with the individual. The domain is well aged since 2013, indicating established presence. There are no detected partnerships or subsidiaries. The site lacks business trust indicators such as certifications or testimonials. Marketing and analytics tools are minimal or absent, suggesting low commercial intent or data collection.

Security posture

The security posture is moderate with HTTPS enabled and no exposed sensitive data. However, the absence of security headers and DNSSEC reduces the overall security maturity. No explicit security policies or incident response contacts are provided, which may limit preparedness for security incidents. The site uses standard WordPress plugins but no advanced security frameworks are evident. Recommendations include enabling DNSSEC, adding security headers, and publishing security and privacy policies to enhance trust and compliance.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  4. Add explicit contact information including email and phone for business and security inquiries.
  5. Consider integrating security frameworks or certifications to demonstrate commitment to security best practices.

Hosting is provided by Websupport.cz, a reputable Czech hosting provider. The site is mobile optimized and uses Google Fonts and JW Player CDN for media.

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.
