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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

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 with a focus on digital solutions for e-commerce and corporate clients, including hospitality and real estate sectors. Their business model is service-oriented, providing tailored digital strategies and implementations. The client list and awards showcase strong market positioning and long-term partnerships, indicating stable revenue streams and growth potential. The agency leverages multimedia content and case studies to demonstrate expertise, enhancing trust and competitive advantage. Partnerships with notable clients and a clear focus on innovation and quality service delivery underpin their market presence. The absence of detailed financial or founding year data limits deeper financial analysis but the extensive client base and project scope suggest a medium-sized enterprise with solid industry standing.

Security posture

The website employs HTTPS with strong SSL configuration and includes multiple security headers, reflecting adherence to best practices. The presence of cookie consent scripts indicates awareness of privacy regulations, though the lack of a dedicated privacy policy page and incident response contacts suggests incomplete compliance. Forms include anti-spam measures, enhancing security against automated abuse. No vulnerabilities or exposed sensitive data were detected in the content. The security score is high but could be improved by publishing formal security policies and incident response information. Overall, the security posture is robust for a digital agency website, supporting safe user interactions and data handling.

Recommendations

  1. Publish a comprehensive privacy policy page clearly outlining data collection, usage, and user rights to enhance GDPR compliance.
  2. Add a terms of service page to define user agreements and legal protections.
  3. Include security incident response contact information to improve transparency and readiness.
  4. Consider implementing and publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Provide contact details for a Data Protection Officer or privacy contact to strengthen trust and compliance posture.

Technical notes

Notes

The website uses modern web standards including HTML5, CSS3, and JavaScript with React JS technology mentioned for e-commerce solutions. It integrates Google Tag Manager for analytics and tracking, and employs web fonts and responsive design for optimal mobile experience. Multimedia content such as videos and interactive elements are used effectively. Performance is moderate with good mobile optimization and accessibility features. No CMS or hosting provider details were identified. The technical implementation supports a professional and engaging user experience but could benefit from explicit CMS or platform identification and performance optimization details.
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.
