DR. PASCAL SIEBER & PARTNERS AG is a Swiss-based independent consulting firm specializing in digital business transformation and ICT strategy. The company offers a broad range of consulting services including strategy, business, software, project, and IT consulting, as well as executive training through their Academy. Their market position is that of a specialist partner for companies and organizations undergoing digital transformation, with a focus on delivering innovative strategies and supporting clients from ideation to implementation. The website is professionally designed, well-structured, and targets business leaders and managers seeking digital excellence. Technically, the site is built on Squarespace CMS, leveraging modern web technologies and integrates Google Analytics and Tag Manager for marketing and analytics purposes. The site is mobile optimized and SEO friendly, providing a good user experience. Security-wise, the site uses HTTPS but lacks some important security headers such as HSTS and CSP, which could be improved to enhance protection against common web threats. Privacy compliance is well addressed with a visible cookie banner and a dedicated privacy policy page in German, indicating GDPR awareness. However, the WHOIS data for the domain is missing or unavailable, which raises concerns about domain registration legitimacy and should be verified. Overall, the website presents a trustworthy and professional image but could benefit from enhanced security headers and verification of domain registration details.

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"

    • 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';…

  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

  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

      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

The company operates in the consulting sector with a focus on digital transformation and ICT. Their business model revolves around providing expert advisory services to enterprises and public organizations, helping them adapt to digital realities and optimize their business processes. The target customers are primarily Swiss-based businesses and public sector entities, as well as non-profit organizations. The firm leverages a multi-service approach including strategy, IT, software, and project consulting, supported by educational offerings through their Academy. The company maintains an active social media presence on LinkedIn, Instagram, Facebook, and YouTube, enhancing their market reach and brand visibility. The lack of WHOIS data is a potential risk factor but does not currently detract from the company's apparent professionalism and market positioning. No parent or subsidiary companies are identified, indicating an independent operation. The website content is rich and relevant, supporting strong business credibility.

Security posture

The website enforces HTTPS, ensuring encrypted communication. However, it lacks several important security headers such as HSTS, Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are recommended to mitigate risks like protocol downgrade attacks, cross-site scripting, clickjacking, and MIME sniffing. The forms on the site appear to be securely implemented with no exposed sensitive data in the HTML. No known vulnerable libraries or security flaws are detected from the provided data. Privacy policies and cookie consent mechanisms are in place, supporting compliance with GDPR. Incident response and security policy information are not publicly available, which could be improved to enhance transparency and preparedness. Overall, the security posture is good but could be strengthened by implementing additional HTTP security headers and publishing security policies.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) header to enforce HTTPS and protect against downgrade attacks.
  2. Implement a Content-Security-Policy (CSP) header to reduce the risk of cross-site scripting (XSS) attacks.
  3. Add X-Frame-Options header to prevent clickjacking attacks.
  4. Add X-Content-Type-Options header to prevent MIME sniffing vulnerabilities.
  5. Publish a clear security policy and incident response contact information on the website.
  6. Verify and update WHOIS domain registration information to ensure domain legitimacy and trust.
  7. Regularly audit third-party scripts and libraries for vulnerabilities.
  8. Maintain and update privacy and cookie policies to reflect current regulations and practices.

Technical notes

Notes

The website is built on the Squarespace platform, utilizing its CDN and infrastructure for hosting and delivery. It uses modern web fonts via Typekit and integrates Google Analytics and Google Tag Manager for tracking and marketing purposes. The site is mobile responsive and well-optimized for SEO with proper meta tags and structured data (JSON-LD) describing the organization and website. Performance is moderate, typical for CMS-based sites with rich media content. Accessibility features are basic but present. The technical stack is modern and stable, but there is room for improvement in security headers and performance tuning. No deprecated or vulnerable libraries are detected in the scripts loaded. Overall, the technical implementation supports a professional and functional web presence.
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.
