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

EVN is a large Austrian energy provider specializing in electricity, gas, heating, water, photovoltaic solutions, and e-mobility services. The website targets private customers, businesses, agriculture, and municipalities, offering a comprehensive range of energy-related products and services. The company maintains a professional and consistent online presence with clear navigation and rich content. Technically, the site uses Kentico CMS, Cloudflare CDN, and integrates analytics tools like eTracker and Microsoft Application Insights. However, the security posture is weak due to the absence of a valid SSL certificate and disabled TLS protocols, which critically impacts secure communications. Privacy and cookie policies are present and GDPR compliant, with a consent mechanism implemented. Overall, the site is trustworthy and professional but requires urgent improvements in SSL/TLS configuration to ensure user security.

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

    • 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 X-Frame-Options header

      Prevents clickjacking attacks

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

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

EVN holds a strong market position as a regional energy supplier in Austria, serving diverse customer segments including private, business, agricultural, and municipal clients. Their business model revolves around energy supply and related services, supplemented by consulting and digital offerings such as a digital assistant. The company leverages partnerships with entities like kabelplus for broadband and telecom services. The website reflects a mature digital strategy with modern CMS and analytics integration, supporting customer engagement and service delivery. EVN's social media presence across major platforms enhances brand visibility and customer interaction. The absence of privacy protection in WHOIS data and consistent domain registration details reinforce legitimacy.

Security posture

The website demonstrates partial adherence to security best practices with several security headers implemented, including CSP, HSTS, X-Content-Type-Options, and X-XSS-Protection. Cookies are set with HttpOnly and Secure flags. However, the lack of a valid SSL certificate and disabled TLS protocols represent critical vulnerabilities, exposing users to potential interception and data compromise. OCSP stapling and session resumption are disabled, reducing performance and security. No explicit incident response or security policy information is found, indicating potential gaps in security governance. The site should prioritize SSL/TLS deployment and enhance security configurations to meet industry standards and regulatory requirements.

Recommendations

  1. Immediately install and maintain a valid SSL/TLS certificate to enable HTTPS and secure user data.
  2. Enable and configure TLS 1.2 or TLS 1.3 protocols with strong cipher suites to protect communications.
  3. Enhance HSTS policy by enabling includeSubDomains and preload directives.
  4. Implement OCSP stapling and session resumption to improve security and performance.
  5. Publish a clear security policy and incident response contact information to improve transparency and readiness.
Technical notes

Notes

The website is built on Kentico CMS and hosted on Azure Web Apps with Cloudflare CDN providing DNS and caching services. It uses modern JavaScript frameworks including Angular for the digital assistant and jQuery for legacy support. External integrations include Google Maps, Google Fonts, eTracker analytics, and FriendlyCaptcha for bot protection. Performance metrics indicate slow loading, possibly due to lack of caching or optimization. SEO is well addressed with proper meta tags and Open Graph data. Accessibility is basic but present. The site is mobile optimized with responsive design. Technical debt is moderate, with opportunities to improve security infrastructure and performance optimization.
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.
