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

Ušetřeno.cz s.r.o. operates a well-established Czech online platform specializing in comparison and brokerage services across energy, finance, insurance, and telecommunications sectors. The company offers consumers tools to compare prices and services such as energy suppliers, loans, mortgages, insurance policies, and mobile tariffs, aiming to help users save money efficiently. As part of the ČSOB group, Ušetřeno.cz benefits from strong market positioning and credibility within the Czech Republic. The website features a professional design, clear navigation, and interactive calculators that enhance user engagement and experience. Technically, the website leverages modern web technologies including Vue.js for frontend interactivity, Google Tag Manager for analytics, and Cookiebot for cookie consent management, reflecting a mature digital infrastructure. The site is mobile-optimized and SEO-friendly, although some accessibility features could be improved. Security-wise, HTTPS is enforced, and cookie consent mechanisms are in place; however, the absence of explicit security headers and a security.txt file indicates room for enhancement in security posture and incident response readiness. The WHOIS data for the domain is unavailable, which raises concerns about transparency and domain registration legitimacy. Despite this, the website's content quality, business information, and affiliation with a reputable financial group mitigate some trust concerns. Overall, the platform demonstrates a solid business and technical foundation with moderate security maturity, suitable for its consumer-facing financial services role. Strategic recommendations include implementing comprehensive security headers, publishing a vulnerability disclosure policy, enhancing accessibility compliance, and improving transparency around domain registration and incident response contacts to strengthen trust and security culture.

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

5 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. 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';…

  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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Ušetřeno.cz holds a competitive position in the Czech market as a multi-sector comparison platform, targeting consumers looking to optimize expenses on utilities, financial products, and telecom services. Its business model relies on affiliate commissions from partners, enabling free user access to comparison tools and calculators. The company leverages its affiliation with ČSOB to enhance credibility and market reach. Growth indicators include a broad service portfolio and integration of exclusive offers. The partnership ecosystem includes insurance providers and job portals, supporting diversified revenue streams. The platform's user-centric approach, combined with digital marketing and analytics, supports effective customer acquisition and retention. Strategic observations highlight the importance of maintaining transparency and security to sustain consumer trust in a sensitive financial services environment.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and cookie consent implemented, aligning with GDPR requirements. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No explicit security policy or incident response contact information is published, limiting preparedness for vulnerability disclosures or security incidents. The use of third-party scripts like Google Tag Manager and Cookiebot introduces potential risk vectors that require regular auditing. Data protection practices appear compliant with GDPR, but enhanced transparency and formalized security governance would improve overall security maturity. The current posture is adequate for consumer trust but should be strengthened to mitigate evolving threats and regulatory expectations.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options.
  2. Publish a security.txt file to facilitate vulnerability reporting and improve incident response transparency.
  3. Enhance website accessibility to meet recognized standards and improve user inclusivity.
  4. Regularly audit and update third-party scripts to minimize security vulnerabilities.
  5. Increase transparency around domain registration and provide explicit security contact channels.

Technical notes

Notes

The website is built using Vue.js, indicating a modern, component-based frontend framework that supports dynamic user interfaces. Google Tag Manager and Cookiebot are integrated for analytics and cookie consent management, reflecting compliance with privacy regulations. The site uses Font Awesome for iconography and includes responsive design elements for mobile optimization. Performance is moderate, with asynchronous loading of scripts and optimized assets. No CMS is explicitly detected, suggesting a custom or proprietary solution. Hosting provider details are not disclosed. Technical debt appears low, but opportunities exist to improve accessibility and security configurations. Overall, the technical infrastructure supports a professional and user-friendly experience with room for security and compliance enhancements.
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.
