Security score

48/100

Risk levelHigh

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

The website ohla-zs.cz is currently inaccessible, returning a 403 Forbidden error page that blocks access to any meaningful content. The domain was registered in 2021 with REG-ZONER as the registrar and uses three name servers under servicio-online.net. No business information, contact details, privacy policies, or security policies are present on the accessible page. The lack of content and contact information severely limits the ability to assess the company's business model, market position, or services. Technically, the site shows minimal implementation with no detectable scripts, analytics, or security headers. The security posture is weak due to lack of HTTPS information and absence of security best practices. Overall, the site appears to be either under maintenance, restricted, or improperly configured, resulting in a low trust and credibility score.

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

11 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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';…

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 · 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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention ohla-zs.cz, from OffSeq Breach.

No leaked records found

Breach holds no records for ohla-zs.cz right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

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 absence of accessible content, no detailed business intelligence can be derived. The domain age suggests a relatively new entity, but no company name, sector, or services are disclosed. No partnerships or subsidiaries are identifiable. The lack of contact information and policies indicates a low level of digital maturity and business transparency.

Security posture

The security posture is poor as the site is inaccessible and does not provide any security headers or HTTPS confirmation. No incident response contacts or vulnerability disclosures are present. The absence of privacy and cookie policies further indicates non-compliance with GDPR and other data protection regulations. The site is effectively blocked, which may be intentional for security or administrative reasons, but this limits external security assessment.

Recommendations

  1. Enable proper website access and resolve 403 Forbidden errors to allow content visibility.
  2. Implement HTTPS with a valid SSL certificate and configure security headers to improve security posture.
  3. Publish comprehensive privacy, cookie, and terms of service policies to comply with legal requirements.
  4. Add clear contact information including emails, phone numbers, and physical addresses to enhance business credibility.
  5. Establish incident response and vulnerability disclosure mechanisms to improve trust and security readiness.

Technical notes

Notes

The website currently serves a static 403 Forbidden error page with no dynamic content or interactive elements. No CMS or frameworks are detectable. The domain is hosted with REG-ZONER, but no further hosting or infrastructure details are available. The site uses Google Fonts for typography but no other external scripts or libraries. Performance and SEO are minimal due to lack of content and meta tags. Mobile optimization and accessibility are basic given the simple error page layout.
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.
