61/100

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

LOKNI s.r.o. is a Czech company dedicated to providing sustainable filtered water solutions primarily targeting schools, municipalities, households, and companies. Their business model includes subscription services and direct sales of reusable bottles, positioning them as a key player in the Czech sustainable water market. The website is professionally designed, well-branded, and rich in content, reflecting a mature digital presence. Technically, the site is built on WordPress with modern plugins and integrates Google analytics with consent management, indicating good digital maturity. Security posture is solid with HTTPS and cookie consent mechanisms, though some security headers could be improved. The absence of WHOIS data reduces trust slightly but does not detract significantly from the overall legitimacy given the professional web presence and clear business information. Strategic recommendations include enhancing security headers, verifying domain registration details, and continuing to maintain strong privacy compliance.

Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

2 findings rated critical or high. Fix these first.

  1. 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

  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.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

LOKNI operates in the education and retail sectors with a focus on environmental sustainability. Their competitive advantage lies in a growing network of over 120 filtration devices and a user-friendly mobile app that tracks water consumption and plastic waste reduction. Revenue streams include subscription plans and e-commerce sales of bottles. The company targets environmentally conscious consumers, schools, and public institutions, leveraging partnerships and social media for brand awareness. Growth indicators include recent news updates and expansion of filtration points. The partnership with lokni-shop.cz for bottle sales complements their core services and enhances customer engagement.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, cookie consent management, and no visible exposure of sensitive data. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. There is no evidence of vulnerability disclosures or incident response policies publicly available, which could be enhanced to improve security culture and readiness. GDPR compliance is well addressed with clear privacy and cookie policies. Overall, the security posture is adequate for the business type but could benefit from formalized security policies and header implementations.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Verify and publish domain WHOIS information or ensure privacy protection is justified and transparent to improve trust.
  3. Develop and publish an incident response policy and vulnerability disclosure program to enhance security culture and readiness.
  4. Continue maintaining GDPR compliance and update privacy policies as regulations evolve.
  5. Enhance accessibility features to improve inclusivity and meet broader compliance standards.

Technical notes

Notes

The website is built on WordPress 6.8.3 with popular plugins such as Yoast SEO and Complianz GDPR for SEO and privacy compliance. It uses jQuery and Owl Carousel for interactive elements and Google Site Kit for analytics integration. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate, with potential improvements in image optimization and script loading. No major technical debt or deprecated technologies were detected. Hosting provider details are not explicitly available. Overall, the technical infrastructure supports a professional and user-friendly experience with opportunities for security and performance enhancements.
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.
