Risk levelHigh

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

AVE Berlin is a small German company specializing in energy consulting and building technology planning, operating since 1999. Their website presents a professional image with clear service offerings including energy consulting, HOAI planning, approvals, construction supervision, assembly planning, and monitoring. The company targets organizations seeking sustainable and efficient energy solutions. Technically, the website uses legacy JavaScript libraries such as jQuery 1.7.2 and includes Google Analytics for visitor tracking. The site is moderately optimized for performance and mobile devices but lacks advanced accessibility features. Security posture is moderate with HTTPS usage implied but no visible security headers or modern protections. Privacy compliance is partial with a privacy policy present but no cookie consent mechanism. No incident response or vulnerability disclosure policies are publicly available. Overall, the website is trustworthy and professional but could improve in technical modernization and compliance transparency.

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. 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: 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 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 · 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

The company holds a niche position in the energy consulting sector in Germany, leveraging long-standing experience since 1999. Their business model focuses on providing specialized consulting and planning services for energy and building technology, targeting energy-intensive process improvements. The website content and structure support a B2B audience with detailed service descriptions and project references. The lack of visible contact details on the homepage may limit direct customer engagement. The partnership with DesignBits for web design indicates a professional approach to branding. No subsidiaries or parent companies are indicated, suggesting an independent small business. The company could benefit from enhanced digital presence and clearer contact channels to strengthen market reach.

Security posture

The website demonstrates a basic security posture with HTTPS usage and no visible sensitive data exposure. However, the use of outdated JavaScript libraries like jQuery 1.7.2 introduces potential vulnerabilities. The absence of security headers such as Content Security Policy, HSTS, or X-Frame-Options reduces defense-in-depth. No public security or incident response policies are disclosed, which may impact trust for security-conscious clients. Google Analytics is implemented without visible cookie consent, posing GDPR compliance risks. Overall, the security maturity is moderate but requires updates and transparency improvements to align with best practices and regulatory requirements.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to current secure versions to mitigate known vulnerabilities.
  2. Implement and display a cookie consent banner to comply with GDPR and improve privacy transparency.
  3. Add and configure security headers such as Content Security Policy, HSTS, and X-Frame-Options to enhance site security.
  4. Publish a security policy and incident response contact information to build trust and readiness for security events.
  5. Improve accessibility and mobile optimization to enhance user experience and SEO performance.

Technical notes

Notes

The website is built with standard HTML5 and CSS, enhanced by JavaScript libraries including jQuery 1.7.2, Nivo Slider, and Lightbox for UI effects. Fonts are loaded via Adobe Typekit. Google Analytics (ga.js) is used for visitor tracking. The site is hosted on servers associated with kasserver.com as indicated by the nameservers. Performance is moderate with no explicit speed optimizations detected. Mobile responsiveness is basic, with viewport meta tags present but no advanced responsive frameworks. No CMS or modern frameworks are detected, indicating a custom or static site architecture. Technical debt is evident in outdated libraries and lack of modern security headers. Opportunities exist to modernize the tech stack, improve performance, and enhance security configurations.
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.
