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

1url.cz is a Czech-based URL shortening service operating since 2010, providing users with the ability to shorten, anonymize, and preview URLs. The service targets general internet users who require shorter, more manageable links for social media, forums, SMS, or affiliate marketing. The website is simple and functional, with clear instructions and integration of Google reCAPTCHA to prevent abuse. Technically, the site uses standard web technologies including HTML, CSS, and Google Fonts, hosted likely by Wedos, the domain registrar. The site enforces HTTPS and uses permanent HTTP 301 redirects for link shortening, ensuring fast and reliable redirection. From a security perspective, the site demonstrates basic best practices such as HTTPS and CAPTCHA protection but lacks published privacy, cookie, or terms of service policies, which are important for compliance and user trust. No advanced security headers were detected, and no direct contact information for security incidents is provided. The domain registration data is consistent with the website content and age, indicating legitimacy and stability. Overall, the website is functional and moderately secure but would benefit from enhanced privacy compliance, improved security headers, and clearer contact information. The content is safe for general audiences with no adult or questionable content detected. The technical implementation is basic but sufficient for the service offered, though mobile optimization and accessibility could be improved.

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. 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

    • 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

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

Business profile

1url.cz operates in the niche market of URL shortening services within the Czech Republic, leveraging a long-standing domain since 2010 to build trust. Its competitive advantage lies in offering permanent redirects (HTTP 301) and optional custom aliases, appealing to users needing reliable and customizable short links. The business model appears to be free service-based, possibly monetized through indirect means such as advertising or partnerships, though no explicit ads or affiliate programs are visible. The target customers are general internet users, including social media users, forum participants, and affiliate marketers. The lack of published business contact details or certifications limits transparency but the stable domain age and consistent WHOIS data support credibility. The service ecosystem includes Google reCAPTCHA for abuse prevention and uses Wedos for domain registration and likely hosting.

Security posture

The security posture of 1url.cz is basic but functional. HTTPS is enforced, and Google reCAPTCHA is implemented to mitigate automated abuse. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. The lack of published privacy and cookie policies represents a compliance gap, especially under GDPR. No incident response contacts or vulnerability disclosure policies are provided, limiting transparency and responsiveness to security issues. No known vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the site is moderately secure but requires improvements in policy publication, security headers, and incident response readiness to enhance trust and compliance.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear terms of service and acceptable use policies to define user responsibilities and legal protections.
  4. Add dedicated contact channels for security incidents, such as abuse@ or security@ email addresses.
  5. Enhance mobile responsiveness and accessibility to improve user experience across devices.

Technical notes

Notes

The website uses a straightforward technology stack with HTML, CSS, Google Fonts, and Google reCAPTCHA for bot protection. The domain is registered and likely hosted by Wedos, a Czech hosting provider. Performance is moderate with no explicit indicators of slow loading but no advanced optimization detected. SEO is basic with meta keywords and description present but no Open Graph or structured data. Accessibility features are minimal, and mobile optimization is basic. No CMS or advanced frameworks are detected, indicating a custom or lightweight implementation. The site uses permanent HTTP 301 redirects for URL shortening, which is a best practice for SEO and link permanence. Overall, the technical infrastructure is stable but could benefit from modernization and enhanced SEO and accessibility features.
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.
