Tennis-Bistro is a small hospitality business operating a lunch restaurant and café located in Talin Tenniskeskus, Helsinki, Finland. The website presents the business as a local dining and catering service provider offering buffet lunches, snacks, and a wide selection of drinks. The target audience is local customers and visitors to the tennis center. The business model focuses on hospitality services with an emphasis on buffet and catering offerings. The website is built on WordPress with Yoast SEO plugin, indicating a moderate level of digital maturity. However, the website suffers from slow loading times and basic mobile optimization. Security posture is weak due to the absence of a valid SSL certificate and HTTPS support, exposing visitors to potential risks.

Contact information is clearly provided, including phone, email, and physical address, along with a Facebook social media link. Overall, the website is functional and professionally presented but requires urgent security and compliance improvements.

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

9 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

  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

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

The business operates in the hospitality sector, specifically targeting local clientele at a tennis center in Helsinki. It leverages a straightforward business model centered on food service and catering. The website content and structure suggest a small-sized enterprise with a localized market presence. The use of WordPress and Yoast SEO indicates an investment in online visibility, but the lack of advanced analytics or marketing tools suggests limited digital marketing sophistication. The Facebook page serves as the primary social media channel, supporting community engagement. The absence of privacy and security policies may expose the business to regulatory risks under GDPR. There is no indication of partnerships or subsidiaries. The business appears focused on maintaining a consistent brand image with quality photographic content and clear service descriptions.

Security posture

The website's security posture is poor, primarily due to the lack of a valid SSL certificate and absence of HTTPS, which is a critical vulnerability exposing users to data interception and man-in-the-middle attacks. No security headers or advanced TLS protocols are enabled. The site does not implement HSTS or OCSP stapling, further weakening its security stance. No incident response or vulnerability disclosure policies are found, indicating limited preparedness for security incidents. The absence of privacy and cookie policies also reflects non-compliance with GDPR requirements. No forms are present on the homepage, reducing attack surface but also limiting user interaction. Overall, the site requires immediate remediation to secure communications and improve compliance.

Recommendations

  1. Obtain and install a valid SSL certificate to enable HTTPS across the entire site.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Develop and publish privacy and cookie policies to comply with GDPR and inform users about data handling.
  4. Optimize website performance to reduce load times and improve user experience, especially on mobile devices.
  5. Establish an incident response plan and consider publishing vulnerability disclosure information to enhance security transparency.

Technical notes

Notes

The website is built on WordPress CMS with the Yoast SEO plugin, leveraging jQuery and Google Fonts for frontend functionality and styling. DNS records indicate hosting with Louhi Networks. The site lacks a valid SSL certificate and does not support any TLS protocols, resulting in unencrypted HTTP traffic. Performance is slow with a load time exceeding 16 seconds and a moderate number of resources (39). Mobile optimization is basic, with responsive meta tags and some CSS adjustments. SEO is enhanced by Yoast SEO plugin and proper meta tags including Open Graph and Twitter cards. No analytics or tracking scripts are detected, indicating minimal user tracking. The absence of security headers and HTTPS is a significant technical risk. The site structure and navigation are clear and consistent, supporting good user experience despite technical shortcomings.
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.
