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

Kadeřnictví MILI is a small local hairdressing business based in Prague, Czech Republic, offering a range of hairdressing services including modern hairstyles, hair coloring, cutting, wedding hairstyles, hair extensions, eyelash extensions, and a mobile hairdresser service to clients' homes. The website targets local residents seeking convenient and personalized hair care services. The business has been operating since 1999, with the domain registered in 2008, indicating a stable presence in the market. Technically, the website is built with basic HTML, CSS, and JavaScript, without modern frameworks or CMS detected. Hosting is provided by HostMonster, as indicated by the nameservers. The site has moderate performance and basic mobile optimization but lacks advanced accessibility features. SEO is basic with meta tags present but no structured data or Open Graph tags. From a security perspective, the site lacks HTTPS enforcement and security headers, which are critical for protecting user data and ensuring trust. No privacy or cookie policies are published, and no contact emails or forms are available for user interaction, limiting compliance with GDPR and other privacy regulations. The site uses a minimal tracking counter from pocitadlo.cz but no major analytics or marketing tools. Overall, the website is functional and provides relevant content for its target audience but requires significant improvements in security, privacy compliance, and technical modernization to enhance trustworthiness and user experience.

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

12 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

  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

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 · found on this site
  • 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 business operates in the local hairdressing sector with a niche offering of home hairdresser services, which differentiates it from typical salons. Its market positioning is that of a small, customer-focused service provider in Prague. Revenue streams likely come from direct service fees for hairdressing and extensions. The absence of online booking or contact forms suggests a reliance on phone bookings. The external links to related local sites indicate some partnership or cross-promotion but no formal affiliations or subsidiaries. Growth potential may be limited by the small scale and lack of digital engagement features.

Security posture

The current security posture is weak due to the absence of HTTPS, security headers, and privacy policies. The lack of secure forms or contact emails reduces the risk of data leakage but also limits user trust and compliance. No incident response or vulnerability disclosure information is provided, indicating low security maturity. The minimal tracking and absence of third-party analytics reduce privacy risks but also limit business intelligence capabilities. Overall, the site is vulnerable to interception and lacks transparency in data protection practices.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure all communications.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and inform users.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Introduce contact email and/or secure contact forms to improve communication and data collection.
  5. Enhance mobile optimization and accessibility to improve user experience and SEO.

Technical notes

Notes

The website uses basic web technologies without modern frameworks or CMS, which simplifies maintenance but limits scalability and features. Hosting via HostMonster is reliable but no CDN or performance optimization detected. The site lacks HTTPS, which is a critical technical deficiency. JavaScript libraries used are minimal and custom (greybox scripts). SEO is basic with meta tags but no structured data or Open Graph tags. The site could benefit from modernization including responsive design, accessibility improvements, and integration of analytics and marketing tools.
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.
