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

e7 GmbH is an Austrian energy and environmental engineering consultancy specializing in energy efficiency, renewable energy, and climate protection. The company offers a broad range of services including energy audits, management, consulting for new construction and renovations, energy innovations, and international projects. Their market position is that of a specialized small enterprise with a strong focus on sustainable energy solutions. The website content is professionally presented, targeting businesses and organizations interested in energy and climate solutions. Technically, the website is built on the webEdition CMS platform and uses Matomo for analytics, reflecting a privacy-conscious approach. However, the site suffers from a lack of HTTPS support and valid SSL certificates, which significantly undermines its security posture. Performance is slow, and no modern TLS protocols or security headers are configured, exposing the site to potential risks. From a security perspective, the absence of HTTPS and security headers are critical vulnerabilities. No explicit security policies or incident response contacts are provided, which could impact trust and compliance. Privacy compliance is reasonably good due to the presence of a comprehensive privacy policy and cookie information, although no explicit consent mechanism is observed. Overall, the website is functional and professional but requires urgent security improvements, especially enabling HTTPS and implementing security best practices. Strategic recommendations include obtaining a valid SSL certificate, enabling HSTS, adding security headers, and enhancing incident response transparency to improve trust and compliance.

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

7 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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 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
  • 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

e7 GmbH operates in the energy sector, focusing on consulting services related to energy efficiency, renewable energy, and climate protection. Their business model revolves around providing expert engineering and consulting services to public and private sector clients. The company leverages partnerships such as membership in Geothermie Österreich and participates in international projects, indicating a collaborative and growth-oriented approach. Their target customers include municipalities, businesses, and organizations aiming for energy transition and sustainability. The company maintains a professional online presence with detailed service descriptions and news updates, supporting their market credibility and growth potential.

Security posture

The current security maturity level of the e7 GmbH website is low due to the absence of HTTPS and valid SSL certificates, which is a critical security flaw. The lack of security headers and modern TLS protocols further weakens the security posture. No incident response or security policy information is available, indicating limited preparedness for security incidents. While no known vulnerabilities such as Heartbleed or POODLE are detected, the basic security hygiene is insufficient for a professional consultancy handling potentially sensitive client data. Compliance with GDPR is supported by a comprehensive privacy policy, but cookie consent mechanisms could be improved. Overall, the security posture requires immediate remediation to protect user data and maintain trust.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  3. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Establish and publish a clear security policy and incident response contact information.
  5. Enhance cookie consent mechanisms to comply fully with GDPR and improve user transparency.

Technical notes

Notes

The website is powered by webEdition CMS, a less common but functional content management system. It uses Matomo analytics, indicating a preference for privacy-friendly tracking. The DNS is managed via DomainControl (GoDaddy), and the site resolves to both IPv4 and IPv6 addresses. Performance is slow with a load time over 10 seconds, which could be improved by optimizing resources and server response times. Mobile optimization and accessibility are good, with responsive design and skip links for navigation. SEO is supported by proper meta tags and Open Graph data. However, the lack of HTTPS and modern TLS support is a significant technical risk. The site would benefit from modernization of its security infrastructure and performance tuning.
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.
