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

Prose London is a small, London-based full-service creative agency and publishing house specializing in identity and culture. The website presents a professional and visually appealing design, targeting creative professionals and businesses seeking branding and creative services. The technical infrastructure leverages modern technologies such as SvelteKit, Sanity CMS, and is hosted on Vercel, ensuring fast performance and good mobile optimization. Analytics are implemented via Plausible Analytics, reflecting a privacy-conscious approach with minimal user tracking. Security posture is generally good with HTTPS enforced and no exposed sensitive data; however, the absence of security headers and security policy documentation indicates room for improvement. Privacy compliance is weak due to missing privacy and cookie policies and lack of consent mechanisms. Overall, the website is legitimate and trustworthy but would benefit from enhanced privacy and security transparency.

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

7 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

Prose London operates in the media sector as a creative agency and publishing house, focusing on identity and culture. The business model revolves around providing creative services and content publishing, targeting a niche market in London. The company appears to be small in size with no public parent or subsidiary companies. The website content and branding are consistent and professional, positioning the company as a specialized creative partner. There is no evidence of extensive partnerships or affiliate programs. Revenue streams likely derive from client projects and publishing activities. The company maintains a modern digital presence but lacks publicly disclosed contact information and formal policies, which could impact client trust and regulatory compliance.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible sensitive data exposure. The use of deferred script loading and minimal tracking enhances security and privacy. However, the lack of standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is provided, limiting transparency and preparedness. The absence of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. Overall, the security posture is adequate for a small creative agency but requires improvements to meet higher standards and regulatory expectations.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with a consent mechanism to improve GDPR compliance.
  2. Add standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against web vulnerabilities.
  3. Provide clear contact information including emails and phone numbers to improve business credibility and user trust.
  4. Establish and disclose a vulnerability disclosure policy or security contact to demonstrate incident response readiness.
  5. Enhance accessibility features and navigation clarity to improve user experience and compliance with accessibility standards.

Technical notes

Notes

The website is built using modern web technologies including SvelteKit for frontend framework and Sanity as the CMS, hosted on Vercel which provides scalable and performant infrastructure. The site uses Plausible Analytics for privacy-friendly user tracking. The HTML and CSS are valid and optimized for fast loading and mobile responsiveness. However, there is a lack of security headers and formal privacy mechanisms. No forms or interactive data collection elements were detected in the provided HTML content. The technical implementation is solid but could benefit from improved security configurations and enhanced accessibility compliance.
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.
