69/100

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

The website e-onkologie.cz serves as an educational portal dedicated to oncology professionals, providing access to the official journal 'Klinická onkologie' and related oncology educational resources. It is affiliated with recognized Czech medical societies (ČLS JEP and SLS) and features partnerships with major pharmaceutical companies, indicating a specialized niche focus in healthcare education. The business model centers on delivering oncology knowledge and journal content to medical professionals in the Czech Republic, positioning itself as a trusted resource within this sector. Technically, the site is built with basic HTML and CSS, incorporating Google Analytics for user tracking. The editorial system is hosted externally via Carecomm. The site lacks modern web frameworks and advanced technical features but maintains moderate performance and basic mobile optimization. SEO and accessibility are present at a basic level, with room for improvement. From a security perspective, the site does not display advanced security headers or policies, and no privacy or cookie policies are published, which impacts compliance with GDPR and best practices. No forms or sensitive data collection are present on the homepage, reducing immediate risk. The domain registration is consistent and legitimate, with no privacy protection, supporting trustworthiness. However, the absence of contact information and security disclosures limits transparency. Overall, the website is a functional, niche educational platform with moderate technical maturity and basic security posture. Strategic improvements in privacy compliance, security headers, and contact transparency would enhance trust and regulatory adherence.

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

Priority findings

3 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 384-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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

e-onkologie.cz operates as a specialized healthcare educational portal focused on oncology, serving medical professionals primarily in the Czech Republic. Its competitive advantage lies in its official affiliation with national oncology societies and partnerships with leading pharmaceutical companies, which bolster credibility and content authority. The business model is content-driven, providing journal access, recommended oncology procedures, and editorial system services. Revenue streams likely include sponsorships and partnerships with pharmaceutical firms. The target audience is oncology specialists and healthcare providers seeking continuing education. Growth indicators include sustained domain presence since 2014 and ongoing partnerships. The ecosystem includes pharmaceutical partners and editorial service providers, reflecting a collaborative approach to oncology education.

Security posture

The website demonstrates a basic security posture with no visible HTTPS enforcement or security headers such as Content Security Policy or HSTS. No privacy or cookie policies are published, indicating gaps in GDPR compliance. The absence of forms reduces attack surface, but lack of incident response contacts or security disclosures limits preparedness. Google Analytics is used without visible consent mechanisms, posing privacy concerns. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is low to moderate, with significant room for improvement in compliance, transparency, and technical security controls.

Recommendations

  1. Implement and publicly display comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Add security headers including Content Security Policy, HSTS, and X-Frame-Options to enhance site security.
  3. Provide clear contact information including security incident response channels to improve transparency and readiness.
  4. Ensure HTTPS is enforced site-wide to protect data integrity and user privacy.
  5. Improve mobile optimization and accessibility to enhance user experience and compliance with standards.

Technical notes

Notes

The website uses a simple technology stack primarily consisting of HTML and CSS, with Google Analytics for tracking. There is no evidence of modern JavaScript frameworks or CMS directly on the site, though editorial management is handled externally via Carecomm. The site performance is moderate with basic mobile responsiveness and SEO meta tags present. Technical debt is indicated by lack of security headers and absence of privacy/cookie policies. Hosting is likely provided by REG-ZONER based on registrar and nameservers. Opportunities exist to modernize the tech stack, improve security configurations, and enhance accessibility and SEO for better digital maturity.
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.
