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

Propeller Digital is a leading London-based digital agency specializing in driving digital growth for clients in hospitality, travel, food & drink, and entertainment sectors. The company offers a comprehensive suite of services including digital strategy, SEO, web development, conversion rate optimization, UX/UI design, social media management, analytics, and paid media campaigns. Their market position is strong, supported by decades of experience and a portfolio of notable clients and successful case studies. Technically, the website is built on modern frameworks such as Next.js and integrates various third-party services like Vimeo for video hosting, Google Tag Manager for analytics, and Tawk.to for live chat support. The site demonstrates excellent performance, mobile optimization, and SEO practices, reflecting a mature digital infrastructure. From a security perspective, the website enforces HTTPS, employs security headers, and uses reCAPTCHA on forms to mitigate spam and abuse. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of explicit security policies and incident response information suggests room for improvement in transparency and preparedness. Overall, the website presents a professional, trustworthy, and well-maintained digital presence. The WHOIS lookup for the 'www.propeller.co.uk' subdomain failed due to an invalid query, but the main domain is presumably properly registered. The business exhibits strong credibility and compliance with privacy regulations, including GDPR. Strategic recommendations include publishing detailed security and incident response policies and enhancing vulnerability disclosure mechanisms.

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. 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 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. 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

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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

Propeller Digital operates as a full-service digital agency targeting ambitious brands primarily in hospitality and related industries. Their competitive advantage lies in their data-driven approach, deep customer insights, and deployment of best-in-class talent. Revenue streams likely include consulting, digital marketing services, web development projects, and ongoing client support. The company maintains a robust partnership ecosystem, including integrations with Shopify Plus and marketing tools like Gorgias. Growth indicators are positive, with multiple case studies showing significant client success. The agency's operations reflect a focus on delivering measurable business outcomes and maintaining long-term client relationships.

Security posture

The website demonstrates a mature security posture with HTTPS enforcement, comprehensive security headers, and use of anti-spam measures such as Google reCAPTCHA. No exposed credentials or vulnerable libraries were identified in the content. However, the lack of publicly available security policies, incident response plans, or vulnerability disclosure information indicates potential gaps in compliance and transparency. There is no visible contact channel dedicated to security incidents or abuse reporting. Overall, the security maturity is good but could be enhanced by formalizing and publishing security governance documents and establishing clear incident response communication channels.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website to enhance transparency and trust.
  2. Implement and publicize a vulnerability disclosure program, including a security.txt file, to encourage responsible reporting.
  3. Provide clear contact information for security incidents, such as a security@ or abuse@ email address.
  4. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance data protection officer visibility and GDPR compliance documentation to strengthen privacy posture.

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.
