Risk levelHigh

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

The website inst.cz is a small-scale portfolio site primarily showcasing web development and internet services projects. It has been active since at least 2012, with content referencing projects dating back to 2009. The site is built on WordPress and uses common web technologies such as jQuery and Highslide JS. Hosting and domain registration are consistent with the Czech hosting provider Wedos. However, the site lacks critical compliance elements such as privacy and cookie policies, terms of service, and contact information, which limits its business credibility and privacy compliance. Security posture is basic with no detected security headers or incident response information, and SSL configuration details are not explicitly available. The content is safe for general audiences and does not contain any adult or questionable material.

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

11 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. 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"

    • 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

Inst.cz operates as a small technology service provider focusing on web design and development, targeting a general audience in the Czech Republic. The business model appears to be service-based with a portfolio showcasing past projects. The market position is local and small-scale with no evident partnerships beyond a couple of related domains listed in the footer. The site does not display certifications or trust indicators, and lacks direct contact channels, which may impact customer acquisition and trust. The company was founded in 2012, consistent with domain age and content timeline.

Security posture

The security maturity of inst.cz is low to moderate. The site uses HTTPS but lacks security headers such as Content-Security-Policy and X-Frame-Options. There is no visible privacy policy or incident response contact information, which are important for GDPR compliance and security incident handling. No vulnerabilities or exposed sensitive data were detected from the content analysis. The site should improve security best practices by implementing headers, updating WordPress and plugins regularly, and providing clear security and privacy documentation.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to comply with GDPR.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information including emails and phone numbers for business and security incident response.
  4. Ensure WordPress core and plugins are regularly updated to mitigate vulnerabilities.
  5. Enhance mobile optimization and accessibility to improve user experience and SEO.

Technical notes

Notes

The website is built on WordPress CMS with jQuery and Highslide JS for interactive image display. It uses Google Fonts for typography. Hosting is provided by Wedos, a Czech hosting provider, consistent with domain registrar data. The site has moderate performance and basic mobile responsiveness. SEO optimization is basic with meta tags present but no advanced structured data or Open Graph tags detected. Accessibility features are minimal. The site could benefit from modernization and technical improvements to enhance performance, 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.
