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

T1 Tallinn operates as a large retail and entertainment shopping center located in Tallinn, Estonia. The website presents a comprehensive overview of the business offerings including retail stores, dining options, entertainment venues, and additional customer services. The site targets a broad audience including families and general shoppers, positioning itself as a key shopping and leisure destination in the region. The business appears well-established with a domain age consistent with its operational history since 2016. Technically, the website is built on WordPress CMS, leveraging modern web technologies such as jQuery, Video.js, and Google Fonts. It uses Cloudflare for DNS and CDN services, ensuring good performance and security. The site is mobile-optimized, accessible, and SEO-friendly, with structured data and meta tags implemented effectively. Analytics and marketing tools like Google Analytics and Facebook Pixel are used for user tracking and marketing purposes. From a security perspective, the website enforces HTTPS and uses clientTransferProhibited domain status to prevent unauthorized transfers. However, DNSSEC is not enabled, and security headers are not explicitly observed, indicating room for improvement. No critical vulnerabilities or exposed sensitive data were detected. Privacy compliance is strong with clear cookie consent mechanisms and a comprehensive privacy policy aligned with GDPR requirements. Contact information is transparent and professionally presented. Overall, the website demonstrates a solid security posture and business credibility with no major red flags. Recommendations include enabling DNSSEC, adding security headers, publishing a security policy, and considering a vulnerability disclosure program to further enhance trust and security maturity.

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

8 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  2. 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

T1 Tallinn is positioned as a prominent retail and entertainment hub in Estonia's capital, serving a diverse customer base with a wide range of services from shopping to leisure activities. The business model focuses on providing a comprehensive consumer experience combining retail, dining, and entertainment. The website reflects a mature digital presence with multilingual support and active social media engagement. Revenue streams likely include retail leasing, food and beverage sales, and entertainment ticketing. The partnership with entities like CINAMON cinema indicates a collaborative ecosystem. Growth indicators include active event promotion and continuous content updates. The company maintains a professional brand image with consistent messaging and clear customer engagement channels.

Security posture

The website exhibits a moderate to strong security posture with HTTPS enforced and domain transfer protections in place. No DNSSEC is enabled, which is a recommended enhancement for DNS security. The absence of explicit security headers such as Content-Security-Policy or X-Frame-Options suggests potential improvements to mitigate common web vulnerabilities. No incident response or security policy documentation is publicly available, which could be a gap in transparency and preparedness. The use of third-party analytics and marketing scripts introduces moderate tracking but is managed with cookie consent mechanisms. Overall, the site is secure for typical retail and informational use but would benefit from enhanced security controls and published policies.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a formal security policy and incident response contact information on the website.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize risk.

Notes

It leverages Google Fonts for typography and integrates Facebook Pixel and Google Analytics for marketing and analytics. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site is well-structured with valid HTML and CSS, optimized for mobile devices, and includes SEO best practices such as meta tags and structured data (JSON-LD). Performance is fast with no broken elements detected. Opportunities exist to improve security headers and enable DNSSEC. The technical implementation supports a positive user experience and business goals effectively.
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.
