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

Iisii solutions GmbH operates a specialized online appointment booking platform (O-TIS) fully integrated with the EVIDENT TIS practice management system, targeting medical practices in Germany. Their solution enables real-time appointment scheduling, automated reminders, and patient self-service, enhancing operational efficiency and patient satisfaction. The company positions itself as an exclusive partner of EVIDENT, emphasizing seamless integration and automation to reduce manual workload in medical practices. Technically, the website is built on WordPress with modern plugins such as WPBakery Page Builder and Borlabs Cookie for GDPR compliance. The site is mobile-optimized and uses HTTPS with secure data transmission. While the technical stack is modern and the site performs moderately well, there is room for improvement in security headers and accessibility features. Security posture is solid with HTTPS and secure forms, but lacks published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is good, with clear privacy and cookie policies and consent mechanisms in place. Overall, the website and business present a professional and trustworthy image with a strong focus on healthcare technology solutions. Strategic improvements in security transparency and technical hardening could further enhance trust and compliance.

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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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 company holds a niche position in the healthcare technology sector, providing a SaaS solution for medical appointment scheduling integrated with a widely used practice management system (EVIDENT TIS). Their business model focuses on B2B services to medical practices, offering value through automation, real-time integration, and patient engagement tools. Revenue likely derives from software licensing, SMS services, and app usage. The partnership with EVIDENT strengthens market credibility and provides a competitive advantage. The target customers are medical practices seeking efficient appointment management and patient communication solutions. Growth potential exists through expanding integrations and enhancing digital patient services.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, secure data transmission, and GDPR-compliant cookie management. The use of CAPTCHA mechanisms on contact forms indicates attention to abuse prevention. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure reduces transparency. Security headers are not detected, which could expose the site to certain web-based attacks. No known vulnerabilities or sensitive data exposures were found. Overall, the security maturity is good but could be improved by publishing security documentation and implementing additional HTTP security headers.

Recommendations

  1. Implement and configure HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information on the website to improve transparency and trust.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit and update all WordPress plugins and themes to mitigate risks from outdated components.
  5. Enhance website accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a WordPress CMS platform using version 6.8.3, enhanced with WPBakery Page Builder for layout management and Borlabs Cookie for GDPR-compliant cookie consent. It uses Bootstrap 4.3.1 for responsive design and FontAwesome 6.1.2 for icons. The site loads scripts and stylesheets efficiently and is mobile-optimized with good SEO meta tags. Performance is moderate, with no major blocking resources detected. The technical stack is modern but could benefit from improved security headers and enhanced accessibility compliance. Hosting provider details are not disclosed. Overall, the technical implementation supports the business goals effectively with room for security and accessibility improvements.
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.
