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 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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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.

Business context

Business profile

DAYLEE operates in a competitive digital marketing landscape with a niche focus on personalization and marketing automation. Their competitive advantage lies in deep expertise with CDPs and data-driven marketing strategies, supported by partnerships with platforms like Spotler, Klaviyo, and Bloomreach. The company targets medium to large e-commerce and leisure businesses seeking to optimize customer engagement and conversion through personalized experiences. Revenue streams likely include consulting, implementation, and ongoing support services. The presence of multiple client testimonials and case studies indicates a growth-oriented approach and strong client retention. Their partnership ecosystem enhances credibility and market reach. Strategic observations suggest continued investment in data insights and AI capabilities to maintain market differentiation.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, reducing risks of common web attacks. The use of Cookiebot indicates attention to privacy and consent management. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy or incident response contact limits transparency in security governance. There is no evidence of a vulnerability disclosure program or security.txt file. Overall, the security measures are adequate for the business type but could be enhanced by publishing formal security policies and incident response procedures to improve trust and compliance.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Add explicit incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to meet higher standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on the Webflow platform, leveraging modern front-end technologies including jQuery, Swiper.js for sliders, and Google Tag Manager for analytics and marketing tags. Cookiebot is used for cookie consent management, ensuring GDPR compliance. Hosting is via Webflow's cloud infrastructure with CDN support from Cloudfront, contributing to fast load times and good performance. The site is mobile-optimized with responsive design and accessibility considerations such as focus-visible outlines. SEO is supported by proper meta tags, Open Graph, and Twitter card metadata. The technical implementation is robust with no broken elements detected. Opportunities exist to further improve accessibility and publish more detailed security and privacy documentation.
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.
