Medium risk. 6 critical or high findings in Security headers, GDPR outside view and 2 other checks.

Security score

70/100

Risk levelMedium

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

The domain www.st-os.com is currently inaccessible, returning a 403 Forbidden error with no visible website content. The WHOIS query indicates that the domain is not registered or inactive, as no registrar or registration data is available. Due to the lack of accessible content, no business information, contact details, or security policies can be identified. The technical infrastructure cannot be assessed beyond the presence of a basic HTTP error response. Security posture is minimal with no security headers or HTTPS information detected. Overall, the website is non-functional and does not provide any information to assess its legitimacy or business operations.

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

6 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 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

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

No business intelligence can be derived from the website due to the absence of content and domain registration data. There is no evidence of market positioning, services, or partnerships. The domain appears inactive or unregistered, which precludes any meaningful analysis of business operations or competitive advantages.

Security posture

The security posture is poor given the complete lack of accessible content and absence of security headers or HTTPS enforcement. The 403 Forbidden error may indicate restrictive server configurations or access controls but does not provide insight into security best practices or incident response readiness. No compliance or data protection measures are evident.

Recommendations

  1. Register and properly configure the domain to enable website accessibility.
  2. Implement HTTPS with valid SSL/TLS certificates to secure communications.
  3. Add standard security headers to improve protection against common web attacks.
  4. Publish privacy, cookie, and terms of service policies to enhance compliance and trust.
  5. Establish clear contact information and business details to improve credibility.
Site observations

Automated reading of the public site. Ratings are indicative.

Generic detected. Website returns a 403 Forbidden error with minimal HTML content and no indication of specific WAF provider branding. These observations may be incomplete. For a fuller analysis, contact guard@offseq.com.

Technical notes

Notes

The website currently serves only a 403 Forbidden error page with minimal HTML content and no metadata, scripts, or external resources. No CMS or technology stack can be identified. The lack of content and domain registration suggests the site is either under development, misconfigured, or abandoned. Performance and SEO cannot be evaluated. Mobile optimization and accessibility are non-existent due to lack of content.
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.
