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

A3 WEB is a French digital agency based in Cholet specializing in the creation of websites, SEO, SEA campaigns, mobile applications, and webmarketing services. With over 20 years of experience, the agency serves primarily small to medium-sized enterprises and local businesses in the Maine-et-Loire and Vendée regions. Their service offerings include bespoke website development, e-commerce solutions, mobile app development using Ionic, and comprehensive digital marketing strategies. The agency emphasizes local presence and personalized client relationships, supported by a professional website with strong SEO and marketing integrations. Technically, the website is built on WordPress with a suite of plugins including Yoast SEO, Ninja Forms, WP Rocket, and Complianz for GDPR compliance. The site uses a valid SSL certificate but lacks modern TLS protocol support and some advanced security headers. Hosting and email services appear to be provided by OVH. Performance is optimized with caching and lazy loading, and the site is mobile-friendly with good SEO practices including structured data. From a security perspective, the site has a valid SSL certificate and no known major vulnerabilities but lacks DNSSEC and HSTS enforcement. Cookie consent is managed properly with a consent mechanism in place. No explicit security policy or incident response information is found. The agency demonstrates good privacy compliance with a comprehensive privacy policy and cookie policy. Overall, A3 WEB presents a solid digital presence with a focus on local market needs, good technical infrastructure, and a moderate security posture. Strategic improvements in security protocols and enhanced transparency on terms of service and incident response would strengthen their trustworthiness and compliance posture.

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

9 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

      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

  2. 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"

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

A3 WEB positions itself as a specialized digital agency serving the Cholet region and surrounding areas, targeting SMEs, TPEs, and local organizations. Their competitive advantage lies in their comprehensive service portfolio, local expertise, and personalized client engagement. The business model is service-oriented, generating revenue through web development, SEO/SEA campaigns, mobile app projects, and webmarketing services. The agency leverages partnerships with local clients and related service providers such as Monclocher for municipal websites. Growth indicators include a diverse client base and integration of modern marketing tools. The agency maintains a strong local brand with consistent messaging and trust signals such as client logos and GDPR compliance.

Security posture

The current security maturity level is moderate. The website employs a valid SSL certificate but does not support modern TLS protocols, which is a significant gap. DNSSEC is not enabled, and CAA records are incomplete, reducing DNS security. The site lacks HTTP security headers like HSTS, Content-Security-Policy, and others that enhance protection against common web attacks. No explicit security policy or incident response information is published, which may impact transparency and readiness. GDPR compliance is well addressed through privacy and cookie policies with consent mechanisms. The absence of a vulnerability disclosure policy or security.txt file limits external security collaboration. Overall, the security posture is adequate for a small digital agency but requires improvements to meet higher standards and regulatory expectations.

Recommendations

  1. Enable TLS 1.2 or TLS 1.3 protocols to ensure secure encrypted communications.
  2. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  3. Activate DNSSEC to protect DNS queries and responses from tampering.
  4. Define and publish proper CAA DNS records to restrict certificate issuance.
  5. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  6. Publish a security policy and incident response contact information to improve transparency.
  7. Regularly update WordPress core and plugins to mitigate vulnerabilities.
  8. Consider implementing a security.txt file and vulnerability disclosure program.

Technical notes

Notes

The website is built on WordPress 5.5.15 with a modern tech stack including Yoast SEO for search optimization, Ninja Forms for data collection, WP Rocket for caching and performance, and Complianz for GDPR cookie management. Hosting and email services are provided by OVH, a reputable French provider. The site uses lazy loading and preloading techniques for performance optimization and is mobile responsive. However, the SSL configuration lacks support for modern TLS versions, which is a technical risk. The site integrates Google Tag Manager and Hotjar for analytics and user behavior tracking. Overall, the infrastructure is solid for a small agency but could benefit from modernization of security protocols and enhanced accessibility features.
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.
