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

KNOW HOW solutions s.r.o. is a Czech-based marketing agency specializing in branding, web design, strategy, content creation, and digital marketing services. Established in 2009, the company positions itself as a creative and sustainable partner for businesses seeking long-term growth and meaningful impact. The website reflects a professional and modern digital presence with clear navigation, rich content, and multiple client testimonials and awards that reinforce its market credibility. Technically, the site employs a variety of modern JavaScript libraries and tracking tools, including Google Tag Manager and Microsoft Clarity, indicating a mature digital infrastructure. Security posture is generally good with HTTPS enforced and cookie consent mechanisms in place; however, the absence of visible security headers and lack of published security policies suggest areas for improvement. The WHOIS data is missing, which reduces domain trustworthiness and should be investigated further. Overall, the site is safe, well-designed, and compliant with GDPR, serving a general business audience effectively.

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

5 findings rated critical or high. Fix these first.

  1. 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

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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

  3. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  4. 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

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

The company operates in the marketing and creative services sector, targeting businesses that value sustainability and long-term strategic growth. Its business model revolves around providing comprehensive marketing solutions including branding, web design, social media management, and performance marketing. The presence of international awards and a diverse client portfolio indicates a competitive market position. The company leverages partnerships and social media channels to enhance its reach and credibility. Revenue streams likely include project-based fees and ongoing marketing service contracts. The website content and client testimonials suggest a focus on quality and client satisfaction, supporting growth and retention. No parent or subsidiary companies are identified, indicating an independent operation.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enabled and a cookie consent mechanism compliant with GDPR. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security is a notable gap. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site uses third-party scripts for analytics and marketing, which should be regularly audited to mitigate supply chain risks. There is no visible incident response or security policy information, which could impact preparedness and transparency. Overall, the security maturity is adequate for the business type but could be enhanced by implementing recommended headers and publishing security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to prevent vulnerabilities from supply chain risks.
  4. Verify and update WHOIS domain registration information to improve domain legitimacy and trust.
  5. Enhance privacy compliance by documenting data retention policies and providing more detailed cookie usage disclosures.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with libraries such as jQuery, Swiper.js for carousels, GSAP and ScrollMagic for animations, and Lenis for smooth scrolling. Google Tag Manager and Microsoft Clarity are integrated for analytics and user behavior tracking. The site loads CSS and JS resources from reputable CDNs, improving performance and reliability. The HTML structure includes accessibility features such as ARIA labels and keyboard navigation support. The site is mobile-optimized with responsive design elements. Performance is moderate, with some videos and images preloaded for better user experience. No CMS is explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not available from the content. Overall, the technical implementation is modern and well-structured, 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.
