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

htp GmbH is a regional telecommunications provider serving the Hannover metropolitan area and surrounding cities in Germany. The company offers a range of services including high-speed internet, fixed-line telephony, mobile telephony, fiber optic connections, and security solutions. The website reflects a mature and professional business with a clear regional focus and customer-centric offerings. The company maintains a presence on major social media platforms and displays customer trust signals such as positive reviews and environmental certifications. Technically, the website is built on the TYPO3 CMS platform, utilizing modern web technologies such as jQuery, lazy loading for images, and accessibility tools. The site is mobile-optimized, well-structured, and includes comprehensive privacy and cookie policies with user consent mechanisms, indicating good digital maturity and compliance with GDPR requirements. From a security perspective, the site enforces HTTPS and uses a reputable cookie consent management system. However, it lacks explicit published security policies, incident response contacts, and security headers, which are areas for improvement. The absence of WHOIS registration data reduces transparency and trustworthiness from a domain registration standpoint, although the website content and external trust indicators support legitimacy. Overall, htp.net presents a trustworthy and professional online presence for a regional telecom provider with good technical and privacy compliance. Strategic enhancements in security transparency and domain registration clarity would further strengthen its security posture and business credibility.

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

4 findings rated critical or high. Fix these first.

  1. 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"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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

      SSL Certificate Expires Soon

      SSL certificate expires in 7 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography

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

htp GmbH operates as a regional telecommunications provider focused on the Hannover area, offering bundled internet, fixed-line, mobile, and fiber optic services. The business model centers on owning and expanding its own network infrastructure, emphasizing fair, personal, and transparent customer relationships. The company targets both residential and business customers, with tailored tariff plans and local shop presence. Partnerships with regional energy and telecom companies (enercity, EWE, swb, etc.) indicate a strong ecosystem and market integration. Customer reviews and environmental certifications suggest a positive brand reputation. The company leverages digital channels for customer engagement, including webmail, customer center portals, and social media. Growth opportunities likely include fiber expansion and enhanced mobile offerings.

Security posture

The website demonstrates a moderate to good security posture with enforced HTTPS and a robust cookie consent mechanism supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and security.txt files limits transparency and preparedness for security incidents. Security headers such as Content-Security-Policy and X-Frame-Options are not evident, which could improve protection against common web attacks. The lack of WHOIS data reduces domain registration transparency, which is a minor risk factor. Overall, the security posture is adequate for a regional telecom provider but could be enhanced by publishing detailed security and incident response information and implementing additional HTTP security headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response and abuse contact information on the website.
  3. Implement and configure HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  4. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Clarify domain registration details and ensure WHOIS information is publicly available to enhance trust.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and widely used content management system, indicating a stable and scalable platform. The use of jQuery 3.7.1 and lazy loading techniques improves user experience and performance. Accessibility features such as the Eye-Able assistive toolbar demonstrate commitment to inclusive design. The site is mobile-optimized with responsive images and clear navigation. SEO is supported by proper meta tags and Open Graph data. The cookie consent is managed by CCM19, a specialized tool for GDPR compliance. Performance is moderate, with potential for optimization in loading times. No critical technical debt or outdated libraries were detected. Hosting provider details are not explicit but likely regional or specialized. Overall, the technical infrastructure supports a professional and user-friendly website experience.
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.
