The company targets businesses seeking to increase web traffic, sales, and inquiries through online marketing strategies.

Technically, the site employs modern front-end frameworks such as Bootstrap and jQuery, integrates Google Analytics, Microsoft Clarity, and Google Tag Manager for analytics and tracking, and offers a responsive design optimized for mobile devices. Security posture is adequate with HTTPS enabled and cookie consent mechanisms in place, though the absence of security headers and a published security policy suggests room for improvement.

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

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

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 positions itself as a specialized digital marketing agency with a focus on SEO and performance marketing. Its business model revolves around service provision to other businesses, leveraging certifications and client references to build trust. The presence of multiple office locations in Prague and Brno indicates a regional footprint. The website's blog and service pages suggest ongoing content marketing efforts to engage and educate potential clients. The use of advanced analytics and tracking tools reflects a data-driven approach to marketing. However, the absence of detailed privacy policies and incident response information may indicate gaps in compliance and security governance. The company appears to maintain partnerships with recognized platforms such as Heureka and Sklik, enhancing its service offerings. Growth potential is supported by a comprehensive service portfolio and active digital presence.

Security posture

The website employs HTTPS, ensuring encrypted communications, and implements a cookie consent banner aligned with GDPR requirements. However, no explicit security headers like Content-Security-Policy or X-Frame-Options were detected, which could mitigate common web vulnerabilities. There is no visible security policy or incident response contact information, limiting transparency in security governance. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of reputable analytics and marketing tools suggests reliance on trusted third-party services. Overall, the security posture is moderate but could benefit from enhanced header configurations, published security policies, and vulnerability disclosure mechanisms to improve resilience and compliance.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a detailed privacy policy page clearly outlining data collection, processing, and retention practices to improve GDPR compliance and user trust.
  3. Establish and publicize a security policy and incident response contact information to demonstrate commitment to security governance and facilitate vulnerability reporting.
  4. Add a vulnerability disclosure or security.txt file to encourage responsible reporting of security issues and improve transparency.
  5. Enhance accessibility features to meet recognized standards, improving usability for all users and potentially boosting SEO.

Technical notes

Notes

The website is built using Bootstrap for responsive design and jQuery for DOM manipulation, supplemented by modern libraries such as MixItUp for filtering and Tiny Slider for carousels. Analytics are implemented via Google Analytics and Microsoft Clarity, with Google Tag Manager managing tags and scripts. The site loads fonts from Google Fonts and uses Ekko Lightbox for media display. Performance appears moderate with asynchronous loading of scripts and lazy loading of images. The site is mobile optimized and includes SEO-friendly meta tags and Open Graph data. No CMS was explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not discernible from the content. Overall, the technical stack is modern and adequate for the business needs, though opportunities exist to improve performance and accessibility.
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.
