Deutscher Verlag für Gesundheitsinformation GmbH · Healthcare · Germany
High risk. 6 critical or high findings in Network security, Security headers and 1 other check.
Leading Medicine Guide is a German healthcare expert portal operated by Deutscher Verlag für Gesundheitsinformation GmbH, founded in 2001. The website provides a curated directory of highly qualified German medical specialists and clinics across various medical fields, targeting patients and healthcare consumers seeking expert medical advice and treatment options in Germany. The business model centers on providing trusted healthcare information and facilitating connections between patients and medical professionals. The site maintains a consistent brand presence and good content quality, supporting its niche market position in the German healthcare sector. Technically, the website employs a moderate technology stack including jQuery, Cookiebot for cookie consent management, Matomo for analytics, and Google Tag Manager. It uses HTTPS and includes structured data for SEO and social media integration. The site is mobile-optimized with good navigation and accessibility features, although some improvements in security headers and performance optimization could be made. From a security perspective, the site implements a comprehensive cookie consent mechanism with granular user controls, indicating good privacy compliance efforts. However, no explicit privacy policy or terms of service pages were detected in the provided content, and WHOIS data is missing or domain registration is unconfirmed, which raises concerns about domain legitimacy. No security policy or incident response information is published, and security headers appear absent, suggesting room for improvement in security posture. Overall, the website is professional and trustworthy in content and business presentation but would benefit from enhanced transparency in domain registration, explicit privacy and security policies, and improved security best practices to strengthen user trust and compliance with data protection regulations.
Scanned
NIS2 Art. 21(2)
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.
6 findings rated critical or high. Fix these first.
Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.
Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server
What to do: Immediately restrict access to PostgreSQL using firewall or VPN
Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer
What to do: Consider restricting access to FTP or implementing strong authentication
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.
Forces HTTPS connections
What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"
Prevents clickjacking attacks
What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"
Controls resources the browser is allowed to load
What to do: Implement a Content-Security-Policy appropriate for your application
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Server supports weak protocols: TLSv1.1
What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

Each check with its score, findings and the evidence it collected.
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
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.
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.

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.
Leaked records that mention leading-medicine-guide.de, from OffSeq Breach.
No leaked records found
Breach holds no records for leading-medicine-guide.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.
Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
