Risk levelLow

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

Slevomat.cz is an e-commerce platform focused on providing discounted experiences and travel deals primarily targeting consumers in the Czech Republic. The website content is accessible and professionally designed, indicating a mature digital presence aimed at leisure and travel customers. However, the absence of WHOIS data limits the ability to fully verify domain ownership and legitimacy. Technically, the site uses standard web technologies with good mobile optimization and SEO practices, but lacks visible advanced frameworks or CMS identification. Security posture is weak due to missing security headers and no visible HTTPS confirmation in the provided data. Privacy compliance is minimal with no detected privacy or cookie policies, which could pose regulatory risks. Overall, the site appears functional and business credible but would benefit from enhanced security and compliance measures.

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

3 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.

    • 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

  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.

  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

      SSL Certificate Expires Soon

      SSL certificate expires in 22 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

The business operates in the e-commerce sector specializing in travel and leisure experiences, targeting local Czech consumers. Its business model revolves around aggregating and selling discounted deals, likely generating revenue through commissions or direct sales. The website's market position appears focused on the Prague region, with a clear audience of experience seekers. Lack of visible partner or subsidiary domains suggests a standalone operation or limited public partnerships. The absence of detailed business registration or contact information reduces transparency but does not negate the apparent operational maturity. Growth potential exists if compliance and security are improved to build greater trust.

Security posture

Current security maturity is low due to missing security headers, no visible HTTPS enforcement in the data, and lack of privacy or cookie policies. No incident response or vulnerability disclosure information is present, indicating limited transparency in security management. The absence of contact channels for security incidents or data protection officers suggests gaps in compliance with GDPR and related regulations. No exposed vulnerabilities or sensitive data were detected in the provided content, but the lack of security best practices reduces the overall security score. The site should prioritize implementing HTTPS, security headers, and clear privacy policies to improve its security posture and regulatory compliance.

Recommendations

  1. Implement HTTPS with a strong SSL/TLS configuration and ensure all pages enforce HTTPS.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  4. Provide clear contact information including support emails and phone numbers for customer and security incident reporting.
  5. Establish and publicize a vulnerability disclosure policy or security.txt file to enhance transparency and trust.

Technical notes

Notes

The website uses standard HTML5, CSS3, and JavaScript technologies with good mobile responsiveness and SEO meta tags. No advanced frameworks or CMS platforms were detected from the provided HTML snippet. Performance appears moderate with no explicit indicators of slow loading or technical debt. Accessibility features are basic but present. The lack of visible analytics or advertising scripts suggests minimal tracking or marketing tools in use. Hosting provider and infrastructure details are not discernible from the data. Overall, the technical implementation is solid but could benefit from modernization and enhanced security integrations.
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.
