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

Sherlock's is a small, themed steakhouse located in Ahaus, Germany, operating within the pub 'The Unbrexit'. The business leverages digital innovation by offering smartphone-based table reservations, ordering, and payment, creating a modern dining experience. The website reflects this digital maturity by using the Chayns platform and React framework, providing a responsive and well-structured user interface. The business hosts special event dinners, enhancing customer engagement and market differentiation. Technically, the website is hosted on reputable infrastructure with HTTPS enabled, but lacks some security headers and formal privacy and cookie policies, which are areas for improvement. Overall, the security posture is solid with no visible vulnerabilities, but compliance gaps exist regarding privacy and cookie consent. The domain registration data aligns well with the business claims, supporting legitimacy and trustworthiness.

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.

Priority findings

8 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 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

  2. 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

  3. 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"

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

Sherlock's targets local customers and visitors interested in a unique dining experience combining traditional steakhouse cuisine with a Sherlock Holmes theme and digital convenience. The business model focuses on hospitality services enhanced by technology, including digital ordering and event hosting. The website's integration with the Chayns platform indicates a strategic partnership with Tobit.Labs, providing a robust digital infrastructure. The company positions itself as a modern, tech-savvy restaurant in a competitive local market, leveraging themed events to attract and retain customers. Growth potential lies in expanding digital services and event offerings. The absence of direct contact emails or phone numbers on the website suggests a preference for digital communication channels, possibly via the integrated chatbot.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and no exposed sensitive data in the HTML. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces the defense-in-depth posture. No vulnerability disclosures or incident response contacts are provided, which limits transparency in security management. The lack of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. The use of modern frameworks and reputable hosting reduces risk, but formalizing security policies and adding security headers would strengthen the overall posture. No signs of malware or phishing were detected.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  5. Enhance accessibility features and provide alternative contact methods such as phone or email for improved customer trust.

Technical notes

Notes

The website is built on the Chayns platform using React and modern JavaScript, ensuring a responsive and interactive user experience. Hosting is managed via Gandi.net DNS services, indicating stable infrastructure. Performance is moderate with some external dependencies on Tobit.Labs services. SEO is well addressed with Open Graph tags and JSON-LD structured data. Mobile optimization is good, supporting a wide range of devices. However, accessibility features are basic and could be improved. The absence of security headers and formal privacy mechanisms represents technical debt. Overall, the technical implementation supports the business model effectively but has room for security and compliance enhancements.
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.
