Medium risk. 9 critical or high findings in GDPR outside view, Email security and 2 other checks.

Security score

50/100

Risk levelMedium

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

The website semma.gr is currently inaccessible due to a Cloudflare Turnstile CAPTCHA security challenge, which blocks direct access to the site's content. As a result, no business information, contact details, or policies are available for analysis. The site appears to be protected by Cloudflare's security services, indicating an intent to mitigate automated access or attacks. However, this also limits the ability to assess the site's content quality, technical infrastructure, and security posture comprehensively. The lack of accessible content and metadata suggests the site is either under maintenance, protected against bots, or experiencing access restrictions.

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

  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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  4. 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 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';…

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

Due to the Cloudflare security challenge, no business intelligence data such as company name, market position, services, or sector information could be extracted. There are no visible contact points, social media links, or business descriptions. The domain is registered under the Greek ccTLD (.gr), but without WHOIS data, no further legitimacy or business context can be established.

Security posture

The presence of a Cloudflare Turnstile CAPTCHA indicates a baseline security measure to prevent automated abuse. However, no security headers or policies are visible due to the blocked content. The SSL/TLS configuration and other security best practices cannot be evaluated. No vulnerabilities or incident response information is available. The security posture is therefore indeterminate but likely relies heavily on Cloudflare's protection mechanisms.

Recommendations

  1. Provide a publicly accessible landing page or business homepage without mandatory CAPTCHA to allow content and policy visibility.
  2. Publish clear privacy, cookie, and terms of service policies to improve compliance and trust.
  3. Add visible contact information including emails, phone numbers, and physical addresses.
  4. Implement security headers and disclose security policies to enhance security posture transparency.
  5. Consider providing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website uses Cloudflare as a hosting and security provider, employing their Turnstile CAPTCHA for bot mitigation. The HTML content is minimal and serves only to present the challenge page. No CMS or additional frameworks are detected. Performance and SEO cannot be assessed due to lack of content. The site uses modern HTML5 and CSS3 standards but lacks metadata and structured data. Mobile optimization and accessibility cannot be evaluated. The technical infrastructure appears to rely on Cloudflare's edge network.
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.
