61/100

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

SCIO is a well-established Czech education services provider specializing in entrance exams, preparatory courses, and educational testing products for students and schools. With over 30 years of experience, SCIO holds a strong market position in the Czech education sector, offering a broad portfolio of services including national comparative exams for universities and secondary schools, as well as professional tools for educators. The website reflects a professional and user-friendly digital presence with clear navigation and comprehensive content tailored to its target audience of students, parents, and educational institutions. Technically, the site employs modern web technologies, including JavaScript, Google Tag Manager, and CookieHub for privacy compliance, and is optimized for mobile devices with good accessibility and SEO practices. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though there is room for improvement in publishing explicit security policies and incident response information. The absence of WHOIS data limits domain trust analysis, but the overall digital footprint and professional presentation support legitimacy. Strategic recommendations include enhancing security transparency and incident response readiness to further strengthen trust and compliance.

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

4 findings rated critical or high. Fix these first.

  1. 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.

  2. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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.

Business context

Business profile

SCIO operates in the education sector, targeting students preparing for university and secondary school entrance exams, as well as schools seeking testing and evaluation tools. Its business model revolves around providing standardized testing services, preparatory courses, and educational projects, generating revenue through exam fees, course enrollments, and institutional partnerships. The company demonstrates competitive advantages through its long-standing market presence, comprehensive service offerings, and integration of scientific research into its products. SCIO maintains a robust partnership ecosystem, including design and UX collaborators and related educational projects. Growth indicators include digital expansion and innovative projects like AI-assisted teaching tools. The company’s operations are primarily focused in the Czech Republic, with related domains serving regional and international audiences.

Security posture

SCIO exhibits a mature security posture with HTTPS enforced site-wide and a cookie consent mechanism aligned with GDPR requirements. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected in the website content. The use of third-party analytics and tracking is managed with user consent. To elevate security maturity, SCIO should consider implementing and publicly sharing a formal security policy, incident response procedures, and a vulnerability disclosure program. These measures would enhance stakeholder trust and compliance with evolving regulatory standards such as NIS2.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information to facilitate reporting and handling of security issues.
  3. Implement security headers such as Content-Security-Policy and X-Frame-Options to harden the website.
  4. Establish and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Continue monitoring and updating privacy compliance measures to maintain GDPR alignment.

Technical notes

Notes

The website is built using modern web standards including HTML5, CSS3, and JavaScript, with integration of Google Tag Manager for analytics and CookieHub for cookie management. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with efficient use of SVG graphics and preloading of fonts. No CMS or hosting provider information was detected. The technical implementation supports a professional user experience but could benefit from enhanced security headers and more explicit technical documentation. Overall, the infrastructure appears stable and well-maintained with opportunities for modernization in security practices.
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.
