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

The website www.dny-teplarenstvi-a-energetiky.cz represents a well-established conference event focused on the heating and energy sectors in the Czech Republic. It serves as a platform for industry professionals, partners, exhibitors, and media to engage in discussions shaping the future of the energy field. The business model centers on event organization and conference hosting, with a strong presence indicated by attendance and partner statistics. The site content is professional and relevant, targeting industry stakeholders. Technically, the website uses legacy JavaScript libraries such as jQuery 1.11.2 and jQuery UI, along with Lightbox.js for UI elements. The site is moderately optimized for performance and mobile use but lacks advanced accessibility and SEO features. No CMS or hosting provider information is evident. Security measures include a cookie consent mechanism; however, no security headers or advanced protections are detected, and the SSL configuration could not be verified from the data provided. From a security perspective, the site shows moderate maturity with no visible vulnerabilities or exposed sensitive data. The absence of WHOIS data for the domain is a concern for domain legitimacy and trust but does not directly impact the operational security of the website. Privacy compliance is supported by an external privacy policy and a cookie consent banner, indicating awareness of GDPR requirements. Contact information is transparent and professional, enhancing business credibility. Overall, the website is functional and professional but would benefit from technical modernization, enhanced security headers, and improved domain transparency. Strategic recommendations include updating JavaScript libraries, implementing security headers, verifying SSL configurations, and publishing incident response and security policies 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

8 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"

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 conference organized by Exponex, s.r.o. targets the energy sector, specifically heating and energy professionals in the Czech Republic. It holds a strong market position with a 32-year history and significant partner and visitor engagement. The business model relies on event hosting, exhibitor services, and networking opportunities. Revenue streams likely include ticket sales, sponsorships, and exhibitor fees. The partnership ecosystem includes the Teplárenské sdružení České republiky and media partners. Growth indicators include consistent event scheduling and content updates. The company maintains professional contact points and transparent organizational information, supporting credibility and operational stability.

Security posture

The security posture of the website is moderate. The presence of a cookie consent banner indicates compliance with privacy regulations. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. The use of an outdated jQuery version may expose the site to known vulnerabilities. No incident response or security policy information is publicly available, which limits transparency and preparedness. The absence of WHOIS data for the domain raises concerns about domain registration legitimacy but does not directly affect website security. Overall, the site would benefit from enhanced security configurations and transparency to improve its security maturity.

Recommendations

  1. Update JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  2. Implement and enforce security headers such as CSP, HSTS, and X-Frame-Options to strengthen web security.
  3. Verify and enforce HTTPS with strong SSL/TLS configurations to protect data in transit.
  4. Publish clear security and incident response policies to improve transparency and preparedness.
  5. Improve accessibility and SEO features to enhance user experience and search engine visibility.

Technical notes

Notes

The website uses legacy JavaScript libraries including jQuery 1.11.2 and jQuery UI, which are outdated and may pose security risks. The presence of Lightbox.js indicates some interactive UI elements. The site lacks modern frameworks or CMS identification. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic with meta keywords and description present but minimal. No analytics or tracking scripts were detected, indicating minimal user tracking. The site structure is clear with well-organized navigation menus. Technical debt is present due to outdated libraries and missing 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.
