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

4 findings rated critical or high. Fix these first.

  1. 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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Yellowgrape operates in the e-commerce sector, targeting organizations seeking to leverage data and technology for business growth. The agency's business model revolves around providing specialized marketing and technology services tailored to e-commerce needs. The website content and structure suggest a medium-sized agency with a consistent brand identity and good content quality. The company uses reputable third-party services for analytics and cookie management, indicating a mature approach to digital marketing and privacy compliance. No direct contact information or certifications were found, which could be areas for enhancement to boost trust and transparency. The absence of WHOIS data due to privacy protection is typical for such businesses and does not detract from legitimacy.

Security posture

The website employs HTTPS and integrates a comprehensive cookie consent mechanism via Cookiebot, demonstrating awareness of privacy and security best practices. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests potential areas for security hardening. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of published security policies, incident response contacts, or vulnerability disclosure programs indicates a gap in transparency and readiness for security incidents. Overall, the security posture is good but could be improved by adopting additional security controls and publishing relevant policies.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  3. Enhance accessibility features to improve compliance and user experience for all visitors.
  4. Provide explicit contact information such as company emails and phone numbers to increase business credibility.
  5. Consider adding certifications or trust badges to reinforce trustworthiness and professionalism.

Technical notes

Notes

The website is built on Webflow CMS, utilizing modern web technologies including HTML5, CSS3, and JavaScript. It integrates Google Tag Manager and Cookiebot for analytics and privacy management, respectively. The site loads external fonts from Google Fonts and hosts assets on a CDN. Performance is moderate with good mobile optimization and basic accessibility features. The technical setup is stable and professional, though there is an opportunity to improve SEO and accessibility further. Hosting appears to be managed by Identity Digital or a related provider, with no signs of technical debt or outdated libraries in the visible content.
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.
