Businessangels.de is a well-established company builder and investor based in Berlin, Germany, with over 26 years of experience in the digital industry. The company focuses on building and investing in medium-sized digital businesses and startups, offering capital, expertise, and network support. Their portfolio includes multiple subsidiaries and successful exits, positioning them as a significant player in the German digital venture capital and company building market. The website reflects a professional and consistent brand image, targeting entrepreneurs, startups, and investors. Technically, the website is built on WordPress with modern JavaScript libraries such as jQuery and Slick Carousel, enhanced by Google reCAPTCHA for form security and a consent management platform for GDPR compliance. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site is mobile-optimized and SEO-friendly, though accessibility features are basic. From a security perspective, the site enforces HTTPS and uses reCAPTCHA to protect forms. However, explicit security headers like CSP and X-Frame-Options are not detected, and no formal security or incident response policies are published. No vulnerabilities or exposed sensitive data were found. Privacy compliance is well addressed with a privacy policy and cookie consent mechanism. Overall, the website and business demonstrate a strong digital maturity and trustworthy presence. Strategic recommendations include enhancing security headers, publishing formal security policies, and improving accessibility. The domain registration and WHOIS data align well with the business claims, supporting legitimacy and trustworthiness.

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

10 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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

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 · found on this site
  • 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

Businessangels.de operates as a company builder and venture capital investor primarily in the technology sector, with a focus on digital businesses and startups in Germany. Their business model combines direct company building, investment, and domain trading. The company leverages its long history since 1999 and a network of subsidiaries to create synergies between new economy digital ventures and traditional industries. Their competitive advantage lies in their experience, capital resources, and network. The target customers are entrepreneurs and startups seeking capital and expertise. The company shows growth through multiple investments and exits, and maintains partnerships with companies like ADCELL and BERMUC. The website content and structure support their market positioning as a reliable and experienced investor and builder.

Security posture

The website demonstrates a moderate to good security posture. HTTPS is enforced, and Google reCAPTCHA v3 is implemented to protect forms from automated abuse. A consent management platform ensures GDPR cookie compliance. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security hardening. No security or incident response policies are publicly available, which could impact transparency and preparedness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The security score is good but could be improved by implementing recommended headers and publishing formal security documentation.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a formal security policy and incident response plan on the website to improve transparency and preparedness.
  3. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities.
  4. Enhance website accessibility features to comply with standards and improve user experience for all users.
  5. Maintain and monitor GDPR compliance, including clear data retention policies and user rights information.

Technical notes

Notes

The website is built on a modern WordPress CMS platform, using jQuery and Slick Carousel for UI components and Google reCAPTCHA v3 for bot protection. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site is mobile-optimized and includes SEO best practices such as meta tags and structured data (JSON-LD). Performance is moderate, with minified CSS and JS assets cached. Accessibility is basic but could be improved. The technical stack is mature and well-maintained, though some security headers are missing. Overall, the infrastructure supports the business needs effectively with room for security and accessibility enhancements.
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.
