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

Alumnii, operated by Paulbergman GmbH, is a specialized SaaS platform focused on providing comprehensive alumni network management solutions primarily for educational institutions, companies, foundations, and associations in Germany. The platform offers integrated services including member management, newsletters, payment processing, event management, job boards, and mentoring functionalities. The company positions itself as a niche provider with a strong emphasis on GDPR compliance and German-based hosting. Technically, the website is built using modern web technologies such as Jekyll for static site generation, Bootstrap for responsive design, and integrates analytics via Matomo. The site is mobile-optimized, accessible, and SEO-friendly, reflecting a mature digital infrastructure. Security measures include HTTPS with strong encryption and Google reCAPTCHA to protect forms, although additional security headers and explicit cookie consent mechanisms are absent. From a security perspective, the site demonstrates good practices with encrypted communications and data protection aligned with GDPR. However, the absence of published incident response contacts and vulnerability disclosure policies suggests room for improvement in transparency and readiness. The WHOIS data aligns well with the website's claims, showing consistent domain registration and hosting in Germany without privacy protection, enhancing trustworthiness. Overall, Alumnii presents a professional, trustworthy, and well-structured online presence suitable for its target audience. Strategic enhancements in security policies and privacy mechanisms would further strengthen its compliance and user trust.

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

8 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"

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

Alumnii operates in the education and technology sectors, targeting alumni organizations such as universities, companies, and non-profits. Its business model revolves around SaaS offerings that streamline alumni management and networking. The company leverages partnerships and client testimonials to build credibility and market presence. Revenue streams likely include subscription fees for platform access and additional services like payment processing. The company maintains an active social media presence and uses third-party platforms like Capterra for reviews, indicating a focus on reputation management and customer acquisition. Growth indicators include a clear product roadmap with features like integrated websites and event management. The company is small-sized and based in Berlin, Germany, with no publicly listed subsidiaries or parent companies.

Security posture

The website exhibits a solid security posture with mandatory HTTPS and SSL encryption using SHA256. Integration of Google reCAPTCHA helps mitigate automated abuse. The hosting is German-based, supporting GDPR compliance claims. However, the lack of explicit security headers such as Content-Security-Policy or X-Frame-Options reduces defense-in-depth. No incident response or abuse contact information is published, which could delay handling of security incidents. No known vulnerabilities or exposed sensitive data were detected in the HTML content. The use of Matomo analytics suggests privacy-conscious tracking. Overall, the security maturity is good but could be enhanced by formalizing incident response and publishing vulnerability disclosure policies.

Recommendations

  1. Implement and publish a cookie consent banner/mechanism to fully comply with GDPR cookie requirements.
  2. Add security HTTP headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  3. Publish an incident response contact or security@ email address to facilitate vulnerability reporting and incident management.
  4. Consider creating and publishing a vulnerability disclosure policy or security.txt file to encourage responsible security reporting.
  5. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable dependencies.

Technical notes

Notes

The website uses a modern static site generator (Jekyll) combined with Bootstrap for responsive design, ensuring good mobile optimization and accessibility. JavaScript libraries such as jQuery, Slick Carousel, Typed.js, and player.js enhance interactivity and user experience. Google reCAPTCHA integration protects forms from spam and abuse. Matomo analytics is used for privacy-respecting user tracking. Hosting is managed via German name servers, consistent with GDPR compliance. Performance is moderate, with no major issues detected. The site lacks some advanced security headers and explicit cookie consent mechanisms, which are technical gaps to address. Overall, the technical infrastructure is solid, modern, and well-maintained.
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.
