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

KPN Webmail is a secure webmail portal provided by KPN, a leading Dutch telecommunications company. The service enables users to access their email accounts online without requiring a dedicated email client, supporting access from any internet-connected PC, including abroad. The website is branded consistently with KPN's corporate identity and links to official KPN support resources, reinforcing its legitimacy and trustworthiness. Technically, the site uses standard web technologies including HTML5, CSS, and JavaScript, with a focus on basic mobile optimization and accessibility. The site enforces HTTPS, ensuring encrypted communication, and uses secure form input practices. However, it lacks visible security headers and does not provide privacy or cookie policies on the login page, which are important for compliance and user trust. From a security perspective, the portal demonstrates a moderate security posture with secure password fields and HTTPS but would benefit from enhanced security headers and published security policies. No vulnerabilities or exposed sensitive data were detected in the provided content. The absence of contact information and incident response details limits user support options. Overall, the website is functional and trustworthy for its purpose but could improve in privacy compliance, security transparency, and user support information to enhance user confidence and regulatory adherence.

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

KPN is a major telecommunications provider in the Netherlands, offering a broad range of services including internet, mobile, and email solutions. The webmail portal serves as a critical access point for KPN's email customers, supporting their communication needs. The business model is service-oriented, focusing on subscription-based telecommunications and internet services. KPN's market position is strong as a leading national provider with a large customer base. The company leverages its brand reputation and extensive infrastructure to maintain competitive advantages. The webmail service integrates with KPN's broader ecosystem, including customer support and mobile email configuration tools, indicating a well-developed partnership and service network. Growth indicators include continuous service updates and integration with mobile platforms. Strategic observations suggest opportunities to enhance digital maturity through improved privacy and security features.

Security posture

The security maturity of the KPN Webmail portal is moderate. The use of HTTPS and secure form inputs are positive indicators. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap in defense-in-depth strategies. The absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms limits transparency and user trust. Compliance with GDPR is not clearly demonstrated on this page, which could pose regulatory risks. No immediate vulnerabilities or exposed sensitive data were identified, indicating a stable security baseline. Enhancing security headers, publishing privacy and security policies, and providing incident response contacts would significantly improve the security posture and compliance readiness.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies accessible from the login page to improve GDPR compliance and user trust.
  2. Add standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to strengthen protection against common web attacks.
  3. Provide clear contact information for security incidents, including abuse and security email addresses, to facilitate responsible vulnerability reporting and incident response.
  4. Enhance mobile optimization and accessibility features to improve user experience and compliance with accessibility standards.
  5. Consider publishing a security.txt file or vulnerability disclosure policy to encourage responsible security research and transparency.

Technical notes

Notes

The website uses a straightforward technology stack consisting of HTML5, CSS, and JavaScript, with deferred loading of scripts to optimize performance. The site includes meta tags for viewport and description, supporting basic SEO and mobile responsiveness. The login form uses appropriate input types and autocomplete attributes, enhancing usability and security. External links point to official KPN domains, maintaining brand consistency. No CMS or advanced frameworks are detected, indicating a custom or lightweight implementation. Performance is moderate with no evident heavy resources. Accessibility is basic, with a noscript fallback message. The site lacks advanced SEO features and structured data such as JSON-LD or Open Graph tags. Hosting and server details are not provided, limiting deeper infrastructure analysis.
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.
