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

OPTEN AG is a Swiss-based professional .NET internet agency specializing in the development of custom web applications, eCommerce platforms, corporate websites, and digital business solutions. The company holds a recognized Umbraco Silver Partner certification, underscoring its technical expertise and commitment to quality. Their website demonstrates a strong market position with a portfolio of reputable clients such as STIHL and the National League. The business targets organizations seeking tailored digital solutions and emphasizes strategy, design, and development services. Technically, the website leverages modern technologies including Umbraco CMS, Google reCAPTCHA, GSAP, ScrollMagic, and Vimeo API integrations. The site is well-optimized for mobile devices, offers good accessibility, and employs SEO best practices. The presence of structured data and a cookie consent mechanism reflects digital maturity and GDPR compliance. From a security perspective, the site enforces HTTPS and uses reCAPTCHA to protect forms, but lacks explicit security policy documentation and incident response contacts. No critical vulnerabilities or suspicious elements were detected. Overall, the security posture is solid but could be enhanced by adding security headers and formal policies. The overall risk assessment is low, with the website presenting a professional, trustworthy, and compliant digital presence. Strategic recommendations include publishing a dedicated security policy, enhancing incident response transparency, and continuous monitoring of third-party libraries to maintain security standards.

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 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 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

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

OPTEN AG operates as a medium-sized technology service provider in Switzerland, focusing on custom software development and digital transformation services. Their competitive advantage lies in their certified expertise with Umbraco CMS and a strong client base in diverse sectors. The business model revolves around delivering tailored digital solutions that integrate seamlessly with clients' existing infrastructures. Revenue streams likely include project-based software development, consulting, and ongoing support. The company targets medium to large enterprises requiring complex web applications and eCommerce platforms. Growth indicators include recent certification achievements and a visible portfolio of high-profile clients. The partnership ecosystem includes Umbraco and Swiss Made Software, enhancing credibility and market reach.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA to mitigate automated abuse, and a cookie consent mechanism aligned with GDPR requirements. However, the absence of published security policies and incident response contacts indicates room for improvement in transparency and preparedness. No exposed sensitive data or vulnerable libraries were identified in the analysis. The site does not currently implement advanced security headers such as Content-Security-Policy or X-Frame-Options, which could further harden the security stance. Overall, the security culture appears professional but would benefit from formal documentation and enhanced header configurations to mitigate emerging threats.

Recommendations

  1. Publish a comprehensive security policy page detailing security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.
  5. Enhance transparency by documenting data retention policies and privacy practices in detail.

Technical notes

Notes

The website is built on a modern technology stack centered around the Umbraco CMS platform, leveraging .NET technologies. It integrates several JavaScript libraries for animations (GSAP, ScrollMagic), UI components (Swiper), syntax highlighting (PrismJS), and lazy loading (LazySizes). The site uses Google reCAPTCHA for form protection and Google Maps API for location services. Performance is moderate with good mobile optimization and accessibility features. The use of structured data (JSON-LD) improves SEO and semantic understanding. Technical risks are minimal but include the need for enhanced security headers and continuous monitoring of third-party dependencies to prevent technical debt and vulnerabilities.
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.
