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

C O R E 1 is a Czech digital agency specializing in AI and advanced web technologies, operating since 2007. They position themselves as leaders in their field, offering services including AI integration, web design, UI/UX, and digital marketing. Their website reflects a professional and modern digital presence with strong branding and client testimonials, targeting businesses seeking innovative web solutions. Technically, the site uses modern web technologies, including Video.js for media, Google Tag Manager, and various marketing and retargeting tools, with a custom CMS named core1/BasicCMS. The site is well-optimized for performance, mobile responsiveness, and SEO. Security-wise, HTTPS is enforced and cookie consent mechanisms are implemented, but there is a lack of published security policies or incident response information. WHOIS data is unavailable, likely due to privacy protection, which is common and justified for this business type. Overall, the site demonstrates a mature digital infrastructure and credible business presence.

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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn

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 technology sector, focusing on AI and web technologies, serving a medium to small business clientele primarily in the Czech Republic. Their competitive advantage lies in combining AI with web development to create smarter, faster, and more profitable websites. They maintain a strong partnership ecosystem, including associations related to UX and AI. The business model is service-oriented, with revenue likely generated from web development projects, AI integration, and digital marketing services. The presence of client testimonials and an active blog indicates ongoing engagement and growth. Their market position is that of a specialized, innovative agency with a solid reputation since 2007.

Security posture

The website demonstrates a good security posture with HTTPS enforced and cookie consent implemented, indicating GDPR awareness. However, no explicit security policies, incident response plans, or vulnerability disclosure mechanisms are published. Security headers are not detected in the provided data, which could be improved. The use of multiple third-party marketing and tracking scripts introduces potential risk vectors that require regular auditing. No exposed sensitive data or vulnerabilities were detected in the content. Overall, the security maturity is moderate, with room for improvement in transparency and technical controls.

Recommendations

  1. Publish a formal security policy and incident response plan on the website to enhance transparency and trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Provide contact information for a Data Protection Officer or security contact to comply with GDPR and improve incident handling.
  5. Regularly review and audit third-party scripts and marketing tools to mitigate supply chain risks.

Notes

The website is built on a custom CMS (core1/BasicCMS) and uses modern web standards including HTML5, CSS3, and JavaScript. It integrates Video.js for video playback and employs Google Tag Manager, Facebook Pixel, and other marketing tools for analytics and retargeting. The site is optimized for fast loading and mobile responsiveness, with good SEO practices evident in meta tags and structured data. Accessibility features are present but could be further enhanced. Hosting provider details are not disclosed. The technical infrastructure supports a professional digital agency's needs with scalable and maintainable components.
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.
