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

FLOWBOX s.r.o. is a Czech-based company specializing in autonomous energy management and optimization solutions for industries, buildings, and cities. Their flagship product, FLOWBOX EMOS, integrates energy data intelligence, microgrid management, and advisory services to help clients reduce energy costs by up to 50%, improve energy resilience, and reduce CO2 emissions. Recognized by Gartner and holding ISO 27001 certification, FLOWBOX positions itself as a trusted vendor in the energy management software market. The company targets industrial clients, municipalities, and building managers, offering tailored solutions with quick ROI and scalable implementation. Technically, the website is built on the Webflow platform, leveraging modern JavaScript libraries such as GSAP for animations, Swiper.js for sliders, and DotLottie for interactive graphics. The site is well-optimized for mobile devices, features clear navigation, and includes GDPR-compliant cookie consent mechanisms. Security practices include HTTPS enforcement and ISO 27001 certification, though HTTP security headers are not explicitly detected. The presence of Cloudflare Turnstile captcha enhances form security. The security posture is strong overall, with no evident vulnerabilities or exposed sensitive data. However, the absence of WHOIS registration data for the domain www.flowbox.com is a notable anomaly that slightly reduces trustworthiness. The website content is professional, comprehensive, and safe for general audiences, with no adult or questionable content detected. Strategic recommendations include adding security headers, publishing a security.txt file, and providing explicit incident response contacts to further enhance trust and compliance. Overall, FLOWBOX demonstrates a mature digital presence with strong business credibility and technical implementation, serving a niche but critical market segment in energy management and sustainability.

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

2 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.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Business profile

FLOWBOX operates in the energy sector, focusing on software solutions for energy management and optimization. Their competitive advantage lies in autonomous control, integration of renewable energy sources, and data-driven decision-making tools. The business model combines software licensing with advisory services, targeting medium to large enterprises and municipalities. The company has a growing international footprint with installations in over 20 countries and more than 300 deployments. Partnerships with recognized entities like Gartner and certifications such as ISO 27001 and Solar Impulse Efficient Solution reinforce their market position. Customer testimonials and case studies across diverse industries indicate strong client satisfaction and operational impact. The company’s growth is supported by a flexible, hardware-agnostic platform that accelerates ROI and supports scalability. FLOWBOX’s strategic focus on sustainability and digitalization aligns with global energy transition trends, positioning it well for future expansion.

Security posture

FLOWBOX exhibits a robust security posture highlighted by ISO 27001 certification, indicating adherence to international information security standards. The website enforces HTTPS and employs Cloudflare Turnstile captcha to protect forms from automated abuse. Cookie consent mechanisms demonstrate GDPR compliance efforts. However, the absence of explicit HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options suggests room for improvement in hardening the web application. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The lack of a published security.txt file and incident response contact information limits transparency for vulnerability reporting. Overall, the security maturity is high but can be enhanced by implementing additional web security headers and formalizing vulnerability disclosure processes.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a security.txt file at the root domain to facilitate responsible vulnerability disclosure.
  3. Add explicit incident response contact information (e.g., security@ or abuse@ email addresses) on the website.
  4. Regularly audit and monitor third-party scripts, especially those from less known domains like 394424.com, to mitigate supply chain risks.
  5. Enhance user privacy transparency by detailing data retention policies and cookie usage in the privacy policy.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern JavaScript libraries such as GSAP for animations, Swiper.js for interactive sliders, and DotLottie for animated graphics. It uses Google Tag Manager for analytics and marketing tags, and Cloudflare Turnstile captcha for bot protection on forms. The site is hosted on Webflow’s platform, ensuring fast loading times and excellent mobile responsiveness. The HTML and CSS are valid and well-structured, supporting accessibility and SEO best practices. The use of multiple deferred and async scripts optimizes performance. However, the inclusion of an external script from 394424.com, an unknown domain, may pose a security risk and should be reviewed. Overall, the technical infrastructure is modern, performant, and scalable, supporting a professional user experience.
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.
