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

N2O is an award-winning brand experience marketing agency established in 1999, specializing in delivering scalable, measurable, and impactful brand experiences and events. The company targets brands seeking experiential, retail, social media, and travel marketing services, positioning itself as a creative agency blending cultural intelligence and human insight to create engaging experiences. The website reflects a professional and consistent brand image with strong trust indicators including multiple industry awards and client testimonials. Technically, the website is built on the Webflow platform, utilizing modern technologies such as Google Tag Manager, Google Analytics, Vimeo for video content, and cookie consent management tools. The site demonstrates good mobile optimization, SEO practices, and moderate performance. Security posture is solid with HTTPS enforced and use of Cloudflare Turnstile captcha on forms, though explicit security headers are not detected. The WHOIS data for the domain is unavailable due to a domain naming rules error from Nominet UK, which raises concerns about domain legitimacy or configuration. Despite this, the website content and business information appear credible and professional. Privacy and cookie policies are present and indicate GDPR compliance. Contact information is primarily via web forms, with no direct emails or phone numbers explicitly provided. Overall, the website presents a mature digital presence with strong business credibility and good security practices, but the lack of WHOIS data and direct contact details suggest areas for further verification and improvement.

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

3 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.

    • 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. 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

N2O operates in the retail and media sectors as a creative brand experience agency with a focus on experiential marketing, retail marketing, social media marketing, and strategic planning. The company has a medium-sized footprint and a well-established market position supported by numerous industry awards and a diverse client portfolio including major brands. Their business model centers on delivering creative marketing campaigns and brand activations that generate measurable impact and advocacy. The agency leverages partnerships and exclusive retail relationships to enhance service delivery. Growth indicators include recent award wins and active content publication. The company maintains a strong digital marketing ecosystem with integrated analytics and advertising tools.

Security posture

The website demonstrates a good security posture with HTTPS enabled and the use of Cloudflare Turnstile captcha to protect forms from automated abuse. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. There is no visible security policy or incident response information on the site, which could enhance transparency and preparedness. Privacy compliance is well addressed with a comprehensive privacy policy and cookie consent mechanism. Overall, the security maturity is solid but could benefit from enhanced header configurations and published security policies.

Recommendations

  1. Implement and enforce explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and readiness.
  3. Provide direct company contact emails and phone numbers to enhance trust and facilitate communication.
  4. Investigate and resolve the domain WHOIS data issue with Nominet UK to ensure domain legitimacy and registration transparency.
  5. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on the Webflow CMS platform, leveraging modern web technologies including Google Tag Manager, Google Analytics, Vimeo embedded videos, and cookie consent scripts. The site uses Google Fonts for typography and integrates third-party marketing and tracking tools such as Leadinfo and Cookie Script. Performance is moderate with good mobile optimization and SEO practices evident in meta tags and structured data. The use of asynchronous script loading and CDN-hosted assets contributes to efficient content delivery. Technical risks are minimal, though reliance on multiple third-party scripts requires ongoing monitoring for vulnerabilities. The site architecture supports a rich user experience with multimedia content and dynamic navigation elements.
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.
