Positioned as a medium-sized agency based in Lille, it serves a diverse clientele including SMEs, mid-sized companies, large enterprises, e-commerce businesses, and retail networks. The company emphasizes bespoke digital solutions and performance-driven marketing strategies, supported by a collective of experts. The website reflects a professional and consistent brand image with strong client references and positive ratings. Technically, the website is built on modern web technologies such as Webflow CMS, enhanced with advanced JavaScript libraries for UI/UX improvements and analytics tools including Matomo, Microsoft Clarity, and Google Tag Manager. The site is fast, mobile-optimized, and incorporates GDPR-compliant cookie consent mechanisms, demonstrating digital maturity and compliance awareness. From a security perspective, the site uses HTTPS and reputable third-party services but lacks explicit published security policies or incident response contacts. No critical vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data reduces transparency and slightly impacts trustworthiness, though the overall business credibility remains high based on content and client evidence. Overall, Dalt presents a strong digital presence with good security posture and compliance practices. Strategic improvements include publishing detailed security and incident response policies and enhancing WHOIS transparency to further strengthen trust and compliance.

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

    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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, LinkedIn, Google APIs, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

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

Dalt operates in the competitive French digital agency market with a focus on digital transformation and marketing services. Its competitive advantages include a broad technology agnostic approach, a collective of specialized experts, and a comprehensive service offering from strategy to execution. Revenue streams likely derive from consulting, project development, marketing campaigns, and long-term digital support contracts. The target customers are primarily B2B companies across various sizes and sectors, with a strong presence in Lille and national reach. The agency maintains an active partnership ecosystem visible through client logos and social media engagement. Growth indicators include 17 years of operation and over 250 clients served. Strategic observations suggest a focus on performance marketing and technology integration as key differentiators.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enforced and cookie consent implemented, aligning with GDPR requirements. Use of reputable analytics and tracking tools with consent mechanisms indicates privacy awareness. However, the absence of a dedicated security policy, incident response contact information, and vulnerability disclosure reduces transparency and preparedness. No security headers were explicitly detected in the provided data, suggesting room for improvement in HTTP security configurations. No vulnerabilities or exposed sensitive data were found, indicating good operational security. Overall, the security maturity is adequate for a digital agency but could be enhanced by formalizing policies and improving header configurations.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and controls.
  2. Provide clear incident response contact information to facilitate reporting and handling of security issues.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance HTTP security headers such as Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on Webflow CMS, leveraging modern JavaScript libraries including Swiper.js for UI components and Lenis for smooth scrolling. Analytics are implemented via Matomo, Microsoft Clarity, and Google Tag Manager, providing comprehensive user behavior insights. Cookiebot manages consent, ensuring GDPR compliance. The site is hosted on Webflow's CDN, contributing to fast load times and excellent mobile optimization. Accessibility features are present but could be further enhanced. The technical stack is modern and well-integrated, supporting a high-quality user experience and efficient content management. Opportunities exist to improve security headers and formalize security documentation to reduce technical risks.
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.
