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

6 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

    • 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. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  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

      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

  • 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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention in45minuten.de, from OffSeq Breach.

Technical appendix

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

Business context

Business profile

IServ GmbH holds a strong market position as a specialized provider of school digitalization solutions in Germany. Their business model focuses on SaaS and on-premises deployments, targeting schools and educational institutions. Key competitive advantages include comprehensive module offerings, strong data protection compliance, and localized hosting. Revenue streams likely derive from subscriptions and service contracts. The company maintains an active partnership ecosystem, including the IServ Academy for training and workshops. Growth indicators include a large user base and multiple certifications. Strategic observations highlight the importance of maintaining compliance and expanding cloud offerings to sustain market leadership.

Security posture

IServ GmbH exhibits a mature security posture with adherence to ISO 27001 and GDPR requirements. The platform ensures data protection through encrypted communications and secure hosting within Germany. No critical vulnerabilities or security misconfigurations were detected in the website content. However, the absence of a public incident response or vulnerability disclosure policy represents a compliance gap. The use of third-party tracking scripts is managed with user consent mechanisms. Overall, the security culture appears strong but could benefit from enhanced transparency and formalized incident handling disclosures.

Recommendations

  1. Publish a dedicated incident response and vulnerability disclosure policy page.
  2. Implement and publicly link a security.txt file to facilitate responsible vulnerability reporting.
  3. Enhance HTTP security headers such as Content Security Policy (CSP) and HTTP Strict Transport Security (HSTS).
  4. Provide direct contact channels for security incidents, e.g., security@iserv.de or abuse@iserv.de.
  5. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a modern JavaScript-based tech stack with integration of Google Tag Manager and Facebook Pixel for analytics and marketing. The platform supports multiple mobile app stores, indicating a multi-platform approach. Hosting is likely managed in German data centers, ensuring compliance with local data protection laws. The site demonstrates fast loading times, responsive design, and good accessibility features. No CMS is explicitly identified, suggesting a custom or proprietary solution. Technical risks are minimal, but continuous monitoring of third-party dependencies is advised to maintain security and performance.
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.
