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

emro s.r.o. is a small Czech Republic-based company specializing in electrical installations, including low voltage security systems, residential and industrial power distribution, and production of electrical switchboards. Established originally in 2003 and restructured as a legal entity in 2010, the company serves commercial and residential clients with a focus on quality electrical infrastructure projects. The website reflects a basic but functional online presence built on the Yola CMS platform, with moderate mobile optimization and basic design quality. Technical infrastructure includes common web technologies such as jQuery and Google Maps integration, hosted via Active24. Security posture is limited, with no visible HTTPS enforcement or security headers, and no published privacy or cookie policies, indicating compliance gaps. Tracking scripts from Yola and SiteWit are present without user consent mechanisms. Overall, the site is legitimate and consistent with the business but requires improvements in security and privacy compliance to enhance trust and regulatory adherence.

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

10 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, focusing on electrical installation services for both residential and industrial clients. Its market position is that of a small, established regional player with a history of notable projects including installations for Lidl stores, residential buildings, and industrial facilities. The business model is service-oriented, relying on project-based contracts. The website lacks extensive marketing or partnership information but shows a stable operational footprint. Growth indicators are limited from the website content, but the company demonstrates a solid foundation with a clear target audience in the Czech Republic. No subsidiaries or parent companies are indicated. The company could benefit from enhanced digital marketing and clearer trust signals to improve competitive advantage.

Security posture

The website's security maturity is low to moderate. Absence of HTTPS enforcement and security headers exposes the site to potential risks such as data interception and clickjacking. The use of an outdated jQuery version may introduce vulnerabilities. No privacy or cookie policies are published, which is a compliance gap under GDPR. No incident response or vulnerability disclosure information is provided, limiting transparency. The lack of secure forms reduces attack surface but also limits user interaction. Overall, the security posture requires significant improvements to meet modern standards and regulatory requirements. Implementing HTTPS, security headers, updated libraries, and privacy policies are critical next steps.

Recommendations

  1. Implement HTTPS with a valid SSL certificate and enforce HTTPS redirects site-wide.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  4. Update jQuery and other libraries to supported secure versions to mitigate vulnerabilities.
  5. Introduce a vulnerability disclosure policy or security contact information to improve transparency and incident response readiness.

Technical notes

Notes

The website is built on the Yola CMS platform using standard web technologies including jQuery 1.11.1 and Google Fonts. It integrates Google Maps via iframe for location display. The site is moderately optimized for mobile devices with responsive CSS rules. Performance is moderate with no explicit speed optimizations detected. SEO optimization is minimal, lacking meta descriptions and keywords. Accessibility features are basic, with no ARIA roles or advanced accessibility markup. The hosting provider is Active24, consistent with the domain registrar. The site uses external analytics and tracking scripts from Yola and SiteWit but lacks cookie consent mechanisms. Overall, the technical implementation is functional but dated and requires modernization to improve security, performance, 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.
