59/100

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

Evides N.V. is a large, established public utility company providing reliable and sustainable drinking water services to approximately 2.5 million consumers and businesses in the southwest Netherlands. The company operates a comprehensive digital infrastructure including a customer portal (Mijn Evides), extensive self-service options, and detailed information resources. Their market position is strong with a focus on quality, sustainability, and customer engagement. Technically, the website is built on modern frameworks like Nuxt.js and Vue.js, hosted on Microsoft Azure, and integrates analytics and marketing tools such as Google Analytics, Hotjar, and Google Tag Manager. Security measures are in place including a strict Content Security Policy and multiple security headers; however, the SSL certificate is currently invalid and no modern TLS protocols are enabled, representing a critical security risk. Privacy compliance is robust with comprehensive GDPR-aligned policies and cookie consent mechanisms. Overall, the site is professional and trustworthy but requires urgent remediation of SSL issues to ensure secure user interactions.

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding rated critical or high. Fix these first.

  1. 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

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

Evides operates in the energy sector as a key regional water supplier with a large customer base. Their business model centers on providing essential water services, supported by digital self-service platforms and extensive customer support channels. The company demonstrates strong community involvement through educational initiatives, sustainability programs, and partnerships with local and international organizations. Their revenue streams include water supply fees, connection services, and ancillary services for both residential and industrial clients. Evides maintains a well-structured content ecosystem with detailed FAQs, service pages, and regulatory information, supporting transparency and customer empowerment. Their partnership ecosystem includes related domains for industrial water, water connection applications, and outage reporting, enhancing service delivery.

Security posture

The website exhibits a moderate security maturity level with several best practices implemented such as a restrictive Content Security Policy, X-Frame-Options, and Referrer-Policy headers. However, the absence of a valid SSL certificate and lack of support for modern TLS protocols significantly undermine the security posture, exposing users to potential risks. The site does not currently implement OCSP stapling or session resumption mechanisms, which could impact both security and performance. There is a responsible disclosure policy with a dedicated security contact email, indicating an awareness of security governance. No critical vulnerabilities or exposed sensitive data were detected in the provided data. Remediation of SSL issues and enhancement of TLS support are critical to improving the security posture.

Recommendations

  1. Immediately renew and correctly install a valid SSL/TLS certificate to enable HTTPS and support modern TLS versions (1.2 or 1.3).
  2. Fully enable and configure HSTS with includeSubDomains and preload options to enforce secure connections.
  3. Review and tighten Content Security Policy to eliminate 'unsafe-inline' and 'unsafe-eval' where possible to reduce XSS risks.
  4. Implement a security.txt file to formalize vulnerability disclosure and improve security communication.
  5. Enable OCSP stapling and session resumption to enhance SSL performance and security.

Technical notes

Notes

The website is built using modern JavaScript frameworks Nuxt.js and Vue.js, indicating a contemporary front-end architecture. It is hosted on Microsoft Azure, leveraging cloud infrastructure. The CMS used is Kentico Kontent, a headless CMS that supports modular content management. The site integrates multiple third-party services including Google Analytics, Hotjar, Google Tag Manager, Vimeo, and YouTube (nocookie variant), reflecting a mature digital marketing and analytics setup. Performance metrics are not available, but the presence of many preloaded scripts and large content suggests potential for optimization. The site is mobile-optimized with good accessibility and SEO practices evident from meta tags and structured content. Technical debt is minimal but SSL misconfiguration is a significant risk. Overall, the technical infrastructure supports a robust and scalable web presence but requires security improvements.
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.
