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

InstaGYM is a Czech-based fitness company specializing in organizing fitness camps primarily in Slovakia and abroad, as well as providing online personal training and nutrition consulting services. The company positions itself as a market leader in its niche, targeting fitness enthusiasts seeking professional training and wellness solutions. The website is professionally designed using modern web technologies such as Nuxt.js and integrates popular analytics and marketing tools including Google Tag Manager, Facebook Pixel, and Exponea. The technical infrastructure supports a good user experience with mobile optimization and moderate performance. Security posture is adequate with HTTPS enforced and no obvious vulnerabilities detected, though security headers could be improved. Privacy compliance is limited due to the absence of a clear privacy policy and terms of service, although a cookie consent mechanism is implemented. The WHOIS data is unavailable, likely due to privacy protection, which slightly reduces trustworthiness but is not uncommon for small businesses. Overall, InstaGYM presents a credible and professional online presence with room for improvement in privacy and security transparency.

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

7 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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

      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.

Business context

Business profile

InstaGYM operates in the fitness and wellness sector with a focus on organizing fitness camps and providing online coaching services. Its business model revolves around connecting clients with expert trainers and nutrition advisors through an online platform, supplemented by physical fitness camps. The company targets a niche market of fitness-conscious individuals in the Czech and Slovak regions. The website's content and branding are consistent and professionally presented, supporting its market leader claim. The use of advanced marketing and analytics tools indicates a data-driven approach to customer engagement. However, the lack of publicly available company registration details and privacy policies suggests potential gaps in regulatory compliance and transparency. The company could benefit from enhancing its trust signals by publishing certifications, detailed business information, and compliance documentation.

Security posture

The website employs HTTPS, ensuring encrypted communication, and integrates several third-party analytics and marketing scripts. While no critical vulnerabilities or exposed sensitive data were found, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a notable gap. The site lacks a published security policy, incident response contacts, or vulnerability disclosure mechanisms, which are important for mature security postures. The cookie consent mechanism is a positive indicator of privacy awareness. Overall, the security maturity is moderate but could be significantly improved by implementing recommended security headers, publishing security policies, and establishing clear incident response channels.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve privacy compliance and user trust.
  2. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Establish and publish a vulnerability disclosure policy and security incident response contacts.
  4. Enhance transparency by providing clear company registration and contact information on the website.
  5. Regularly audit third-party scripts and tracking tools to minimize security and privacy risks.

Technical notes

Notes

The website is built using Nuxt.js, a modern Vue.js framework supporting server-side rendering, which enhances SEO and performance. It uses popular JavaScript libraries and integrates Google Fonts for typography. Analytics and marketing tools such as Google Tag Manager, Facebook Pixel, and Exponea are embedded for user tracking and campaign management. The site is mobile-optimized and shows good design quality. However, the absence of a detected CMS suggests a custom or static site build. Performance is moderate, likely influenced by multiple external scripts. There is no explicit hosting provider information. Technical debt appears low, but improvements in security headers and privacy documentation are needed to reduce risks and align with best practices.
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.
