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

NFON AG is a large German technology company specializing in cloud-based telephony solutions, particularly cloud PBX systems for businesses across Europe. The company targets business customers seeking scalable and flexible telephony services delivered via the cloud. Their market position is strong as a leading European cloud PBX provider, offering unified communications and telephony solutions. Technically, the website infrastructure is minimal with a geoip2-based country redirect script and hosted on myracloud. However, the site lacks a valid SSL certificate, resulting in no HTTPS support and poor security posture. Email security is well configured with valid SPF and DMARC records, and DNS records indicate professional email handling via Mimecast. The website content is minimal, lacking metadata, structured data, or visible business contact information, which negatively impacts user experience and trust. Security headers are partially implemented but critical TLS protocols and cipher suites are missing, exposing the site to risks. Overall, the site has a low security score and poor privacy compliance, with no visible privacy or cookie policies. Strategic improvements are needed to install valid SSL, enhance security headers, publish privacy and cookie policies, and improve website content and professionalism.

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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  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"

    • 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

NFON AG operates in the cloud telephony sector with a B2B SaaS business model. Their competitive advantage lies in providing cloud PBX solutions that enable businesses to manage telephony flexibly. The company likely generates revenue through subscription services for telephony solutions. The target customers are businesses across Europe requiring unified communications. The domain age and WHOIS data align with the company's founding date and business claims, supporting legitimacy. The company uses professional email security services and DNS infrastructure. However, the website lacks marketing and analytics tools, and no social media presence was detected in the provided content. The absence of privacy and security policies and contact details online may hinder customer trust and compliance with regulations such as GDPR.

Security posture

The current security posture is weak due to the absence of a valid SSL certificate and HTTPS support, which is a critical vulnerability. Although SPF and DMARC records are correctly configured, the lack of TLS protocols and strong cipher suites exposes the site to interception risks. Security headers are partially present but incomplete. No security policy, incident response contacts, or vulnerability disclosure mechanisms are published. The site does not implement OCSP stapling or session resumption, impacting both security and performance. These gaps indicate a low maturity level in security practices, posing risks to data confidentiality and user trust. Immediate remediation of SSL and TLS issues is essential, alongside publishing security policies and improving incident response readiness.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the site.
  2. Enable modern TLS protocols (TLS 1.2 or 1.3) and configure strong cipher suites.
  3. Publish comprehensive privacy and cookie policies with GDPR compliance indicators.
  4. Add clear contact information including security incident response channels.
  5. Implement security.txt and vulnerability disclosure policies to enhance transparency and trust.
Technical notes

Notes

The website uses a minimal JavaScript-based geoip2 country redirect mechanism and is hosted on myracloud infrastructure. DNS records are professionally managed with multiple authoritative nameservers and email security via Mimecast. However, the lack of valid SSL certificate and TLS support severely limits secure communications. No CMS or frameworks were detected, indicating a possibly static or custom-built site. Performance data is missing, but the minimal content suggests slow or incomplete loading metrics. SEO and accessibility features are absent or minimal due to lack of metadata and structured data. The technical debt includes outdated or missing security configurations and lack of modern web standards implementation, which could impact business operations and user trust.
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.
