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

    • 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

FLEKSI operates in the real estate sector focusing on flexible workspace solutions. Their business model includes short and long-term rentals of offices, coworking desks, event spaces, and meeting rooms. The company targets professionals and businesses in Prague seeking adaptable office environments. Their parent company, Passerinvest Group, supports their operations, indicating strong backing and real estate expertise. The company leverages a multi-location strategy within a prominent business district, enhancing competitive advantage. Their marketing ecosystem includes Google Ads, Facebook, LinkedIn, and Seznam retargeting, showing active digital marketing efforts. The presence of certifications and internal rules documents reflects a professional and regulated business environment.

Security posture

The website demonstrates a good security posture with HTTPS enforced and use of Google reCAPTCHA on forms to prevent spam. Cookie consent and GDPR compliance are implemented, showing attention to privacy regulations. However, explicit security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not evident in the HTML content, which could be improved to mitigate risks such as clickjacking and MIME sniffing. No exposed sensitive data or vulnerable libraries were detected. The absence of a public security policy or incident response contact is a minor gap. Overall, the security maturity is good but could benefit from enhanced HTTP header configurations and published security policies.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Conduct regular audits of third-party scripts and libraries to ensure no vulnerabilities are introduced.
  4. Enhance accessibility features to improve compliance with standards and user experience for all visitors.
  5. Maintain and update GDPR and cookie consent mechanisms to align with evolving privacy regulations.

It leverages multiple third-party services such as Google Tag Manager, Google Analytics, Facebook Pixel, LinkedIn Insight Tag, and Seznam retargeting for marketing and analytics. The site integrates with Nexudus platform for workspace management and Stripe.js for payment processing. Performance is moderate with asynchronous loading of scripts and preloading of critical CSS.

The site uses Google Maps API for location services and Google reCAPTCHA for form security. Overall, the technical infrastructure is robust and supports the business needs effectively.
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.
