Security score

37/100

Risk levelHigh

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

The website tallinn.ee is currently inaccessible beyond a Cloudflare Turnstile security challenge page, which prevents full content and security analysis. The domain is registered since 2010 with an Estonian registrar consistent with the website's country of origin, indicating legitimacy. The visible page only shows a human verification prompt with no business or contact information, privacy policies, or terms of service. The technical infrastructure relies on Cloudflare services for security and analytics. Due to the access restrictions, the website's content quality, privacy compliance, and security posture cannot be fully assessed. The lack of exposed contact or policy information limits trust and transparency from a user perspective.

NIS2 and GDPR posture

GDPR outside view: 10/ 100 · Critical
Checks completed: 7of 7

NIS2 Art. 21(2)

(a) Risk analysis and security policies: Not visible from outside
(b) Incident handling: One indicator
(c) Business continuity, backups and crisis management: Not visible from outside

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

20 findings rated critical or high. Fix these first.

GDPR outside view

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.

Counted in this score

SSL/TLS: 0
Security headers: 70
Email security: 60
DNS health: 80
Network security: 0
GDPR outside view: 10
Average: 37

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 · found on this site
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

Tallinn.ee appears to be a government-related website for the city of Tallinn, Estonia, based on domain and registrar data. The domain age and registrar align with an established public sector entity. However, no direct business descriptions, services, or contact details are accessible on the challenge page. The website likely serves residents and visitors of Tallinn, providing municipal services and information. The use of Cloudflare indicates a focus on security and performance, but the current access block limits visibility into the site's full business model and digital presence.

Security posture

The website employs Cloudflare's Turnstile CAPTCHA and security challenge mechanisms, indicating a proactive approach to mitigating automated threats and abuse. However, the lack of visible security headers or policies on the accessible page prevents a detailed security posture evaluation. No vulnerabilities or exposed sensitive data were detected in the limited content. Incident response contacts and security policies are not publicly visible, which is a gap in transparency. Overall, the security posture appears cautious but cannot be fully validated due to content blocking.

Recommendations

Enable access to at least a basic landing page without WAF challenge to allow content and compliance analysis.
Publish clear privacy and cookie policies compliant with GDPR and other regulations.
Provide visible contact information including general and security incident contacts.
Implement and expose security headers and best practices on public pages.
Enhance transparency by publishing security policies, incident response procedures, and data protection officer contacts.

Site observations

Automated reading of the public site. Ratings are indicative.

Cloudflare detected. Website content is blocked by Cloudflare security challenge (Turnstile captcha). Only a challenge page with minimal content is accessible. These observations may be incomplete. For a fuller analysis, contact guard@offseq.com.

Key observations

Website content is inaccessible due to Cloudflare Turnstile challenge.
No visible privacy, cookie, or terms of service policies on the accessible page.
No contact information or business details are exposed on the challenge page.
Technical stack includes Cloudflare security and analytics services.
WHOIS data indicates a legitimate domain registration consistent with Estonian government entity.
Unable to perform full content, security, and compliance analysis due to access restrictions.

Technical notes

Notes

The website uses Cloudflare services extensively for security (Turnstile CAPTCHA) and analytics (Cloudflare Insights). The HTML content is minimal and primarily serves the security challenge. No CMS or other frameworks are detectable from the limited content. Hosting is via Cloudflare's edge network. Performance and SEO cannot be assessed due to lack of content. The technical setup prioritizes security but at the cost of accessibility for automated analysis. Modern JavaScript and CSS practices are used in the challenge page styling.

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.
