Risk levelHigh

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

The website www.penb-audit.cz represents a small Czech company specializing in energy consulting services, particularly focused on the Nová zelená úsporám subsidy program, energy performance certificates (PENB), and energy audits. The company has a proven track record with over 100 successfully processed subsidy projects, targeting homeowners and commercial property owners seeking energy efficiency improvements. The website is professionally designed, uses HTTPS, and provides clear contact information, although it lacks privacy and cookie policies which are important for GDPR compliance. Technically, the site is built on WordPress 4.9.3 and uses older versions of jQuery and jQuery Migrate, which may expose it to security vulnerabilities. The site includes Google Analytics and Google Tag Manager for tracking, but no advanced security headers were detected. The performance and mobile optimization are moderate to basic, with room for improvement in accessibility and modern technology adoption. From a security perspective, the site benefits from HTTPS but lacks explicit security headers and uses outdated JavaScript libraries. The absence of WHOIS registration data reduces trustworthiness and raises concerns about domain legitimacy. No privacy or cookie policies were found, indicating compliance gaps with GDPR and related regulations. No incident response or security policy information is available. Overall, the website is functional and professional but requires updates to its technical stack, improved security practices, and enhanced privacy compliance to strengthen its security posture and trustworthiness.

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

The company operates in the energy sector within the Czech Republic, focusing on energy efficiency consulting and subsidy facilitation. Its business model revolves around providing specialized services for energy audits, certification, and subsidy application assistance. The target market includes residential and commercial property owners interested in energy savings and government subsidies. The company appears to be a small-sized entity with a niche market position and a history of successful project completions. Partnerships with web design and branding firms are evident, but no broader partnership ecosystem or subsidiaries are identified. Revenue streams likely derive from consulting fees and certification services. Growth indicators are not explicitly stated but implied by the volume of projects handled.

Security posture

The current security maturity level is moderate but with notable gaps. The use of HTTPS is a positive baseline, but the absence of security headers such as Content-Security-Policy and X-Frame-Options weakens defense-in-depth. Outdated JavaScript libraries present potential vulnerabilities that could be exploited. No evidence of incident response readiness or published security policies was found. Data protection practices are minimal, with no privacy or cookie policies visible, which is a compliance risk under GDPR. The contact form includes a basic anti-spam hidden field but lacks stronger protections like CAPTCHA. Overall, the security culture appears basic and could benefit from formalization and modernization.

Recommendations

  1. Update all JavaScript libraries, especially jQuery and jQuery Migrate, to their latest secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive privacy and cookie policies to ensure GDPR compliance and improve user trust.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  4. Introduce stronger anti-spam measures on contact forms, such as CAPTCHA or honeypot techniques, to reduce spam and abuse.
  5. Obtain and publish clear WHOIS registration data to improve domain legitimacy and trustworthiness.

Technical notes

Notes

The website is built on an older version of WordPress (4.9.3) and uses legacy JavaScript libraries (jQuery 1.11.1 and jQuery Migrate 1.2.1), which are outdated and potentially vulnerable. The site loads external scripts from Google Analytics and Google Tag Manager for tracking purposes. The HTML structure is valid with proper meta tags and SEO optimizations, including Open Graph tags for social sharing. Mobile optimization and accessibility are basic but functional. Hosting provider details are not discernible from the data. Performance is moderate, with no explicit indicators of slow loading but also no advanced optimization techniques detected. The site lacks modern frameworks or platforms beyond WordPress and jQuery.
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.
