Their offerings span consulting, development, operation, and support, with a focus on quality and user experience. The website reflects a mature digital presence with comprehensive content, clear navigation, and strong branding consistency. Technically, the website employs modern frameworks and technologies, including TYPO3 CMS, nopCommerce for digital commerce, and integrates AI capabilities through their Intersim AI product. The site is mobile-optimized, uses Vimeo for video content, and incorporates Google Tag Manager and Usercentrics for analytics and consent management, indicating a well-rounded digital infrastructure. From a security perspective, the site enforces HTTPS, implements standard security headers, and uses Google reCAPTCHA to protect forms.

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

5 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

    • 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

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Intersim AG operates as a medium-sized Swiss technology company focused on delivering tailored digital solutions. Their market positioning is strong within the Swiss digital agency landscape, supported by a portfolio of reputable clients such as Swissgrid AG, Kanton Solothurn, and others. The company leverages agile methodologies and modern tech stacks to meet individual customer needs, including AI integration and multi-platform app development. Revenue streams likely derive from consulting, software development, hosting, and ongoing support contracts. The company maintains a partnership ecosystem with technology providers and clients, emphasizing quality and innovation. Growth indicators include active blog content, certifications, and a visible recruitment presence, signaling ongoing expansion and talent acquisition.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, including HSTS, CSP, and X-Frame-Options. Use of Google reCAPTCHA and Usercentrics consent management enhances protection against automated abuse and supports privacy compliance. No exposed credentials or vulnerabilities were found in the HTML content. However, the lack of a published security policy or incident response contact limits transparency and preparedness for security incidents. The company holds recognized certifications (IQNET, SQS) which imply internal security and quality management practices. Overall, the security maturity is high but could benefit from enhanced public-facing security documentation and vulnerability disclosure mechanisms.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information (e.g., security@ or abuse@ email).
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance form security with anti-CSRF tokens and monitor login attempts for brute force protection.

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.
