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

Arkone is a French-based agency specializing in bespoke web and mobile application development, targeting businesses and startups primarily in France. Founded in 2021, the company positions itself as a 100% French, custom solution provider with a focus on quality and client satisfaction. Their key services include mobile app development, web development, event-related digital services, and startup accompaniment. The website reflects a professional and consistent brand image, supported by active social media channels and structured data for SEO. Technically, the website is built on WordPress using the Divi theme, enhanced with Yoast SEO and Google Analytics for performance and marketing insights. Hosting is provided by OVH, a reputable French hosting provider, with DNS managed via Cloudflare. The site is mobile optimized and performs moderately well, though accessibility features are basic. The presence of a cookie consent mechanism indicates some level of privacy compliance. From a security perspective, the site enforces HTTPS and uses Cloudflare DNS, but lacks several recommended security headers and does not publish a security policy or vulnerability disclosure. No critical vulnerabilities or WAF blocking were detected, but improvements in security headers and incident response transparency are advised. Overall, Arkone's website demonstrates a solid business and technical foundation with room for enhancement in privacy and security compliance. The risk level is moderate with no immediate critical issues, making it a trustworthy digital presence for a small technology agency.

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

11 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

  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.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • 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 SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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

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 · found on this site
  • 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

Arkone operates as a small, specialized technology agency focusing on custom mobile and web development services in the French market. Their business model is service-oriented, catering to startups and businesses requiring tailored digital solutions. The company leverages a modern CMS platform and SEO best practices to maintain visibility. Their social media engagement on Instagram, LinkedIn, and Facebook supports brand awareness and client outreach. The domain age and registration details align with the company's recent founding, indicating consistency and legitimacy. No partnerships or subsidiaries were identified from the website content. The agency's competitive advantage lies in its French identity and bespoke service approach.

Security posture

The website exhibits a basic to moderate security posture. HTTPS is properly implemented, ensuring encrypted communications. DNS is managed via Cloudflare, which can provide additional security benefits. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No security.txt or vulnerability disclosure policy is published, limiting transparency and incident response readiness. The cookie consent mechanism is present, supporting GDPR compliance to some extent. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is adequate for a small agency but should be improved to meet higher standards.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to enhance protection against web vulnerabilities.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure page or security.txt file to encourage responsible reporting of security issues.
  4. Ensure all forms include anti-CSRF tokens and robust input validation to prevent injection attacks.
  5. Enhance privacy compliance by publishing a detailed privacy policy and terms of service accessible from the main navigation.

Technical notes

Notes

The website is built on WordPress CMS with the Divi theme, a popular and flexible framework for web development. It uses jQuery and integrates Google Tag Manager and Google Analytics for tracking and marketing purposes. Hosting is provided by OVH, a reputable French provider, with DNS managed by Cloudflare, indicating a reliable infrastructure. The site is mobile optimized and SEO friendly, leveraging Yoast SEO plugin and structured data (JSON-LD). Performance is moderate, with caching and minification plugins in use. Accessibility features are basic and could be improved. The technical stack is modern and suitable for the agency's business needs, though security enhancements are recommended.
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.
