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

Interenergo d.o.o. is a medium-sized energy company based in Slovenia, operating as part of the Austrian Kelag group since 2009. The company focuses on renewable energy investments, energy efficiency solutions, power purchase agreements, and energy trading across Southeast Europe. Their website is professionally designed with clear navigation and bilingual support, targeting businesses and investors interested in green energy solutions. Technically, the site uses modern JavaScript libraries and cookie consent mechanisms but lacks a valid SSL certificate, which is a critical security gap. Security headers are partially implemented, but the absence of HTTPS significantly lowers the security posture. Contact information and privacy policies are clearly provided, supporting GDPR compliance. Overall, the website is functional and trustworthy but requires urgent improvements in SSL/TLS implementation to enhance security 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

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

Interenergo holds a strong regional market position in Southeast Europe with presence in seven countries. Their business model revolves around developing renewable energy projects, providing energy efficiency services, and trading energy on multiple wholesale markets. The company leverages its parent Kelag's century-long energy industry experience, enhancing credibility. Their target customers include developers, landowners, power producers, investors, companies, and public sector entities. The website content and structure reflect a professional corporate approach with clear service offerings and success stories, indicating a mature business with growth potential. Partnerships with related Austrian energy companies are evident from linked domains and CSP policies.

Security posture

The website's security posture is weak due to the lack of a valid SSL certificate and absence of HTTPS support, exposing users to potential interception risks. While security headers like Content-Security-Policy and Strict-Transport-Security are present, HSTS is not effectively enabled, and the X-XSS-Protection header is disabled. No evidence of incident response or vulnerability disclosure policies is found. Cookie consent is implemented via Cookiebot, supporting privacy compliance. The site uses external trusted services for analytics and marketing but should prioritize securing transport layer encryption and enhancing security headers to mitigate risks.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable and configure HSTS with includeSubDomains and preload directives to enforce secure connections.
  3. Enable X-XSS-Protection header or strengthen CSP to protect against cross-site scripting attacks.
  4. Publish explicit terms of service and security policy pages to improve transparency and compliance.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.

Technical notes

Notes

The website uses a custom or proprietary CMS framework (modules3) with JavaScript libraries such as Swiper.js for sliders and Cookiebot for cookie consent management. Google Tag Manager is used for analytics and marketing tags. The site is bilingual (Slovenian and English) with a responsive design optimized for mobile devices. Performance metrics are not provided, but the site includes preloading of fonts and scripts. Accessibility is basic with some ARIA roles and labels. SEO is basic with meta description and viewport tags but no Open Graph or JSON-LD structured data detected. The lack of SSL/TLS is a major technical deficiency. DNS records appear missing or not detected, which may indicate scanning limitations or DNS misconfiguration.
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.
