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

iSun AG is a Swiss-based custom software development company specializing in blockchain technology, fintech solutions, and compliance software. Their offerings include exchange software, asset digitization, banking software, compliance tools, virtual and physical debit cards, money transfer software, and payment gateways. The company targets businesses requiring advanced, secure, and tailored digital financial solutions, positioning itself as a niche technology provider in the Swiss and European markets. The website reflects a professional and consistent brand image with clear navigation and relevant content. Technically, the site is built using modern frameworks such as Hugo and Bootstrap, with integration of analytics and tracking tools like Google Analytics and Google Tag Manager. Security posture is solid with HTTPS enforced and secure form handling, though the absence of security headers and incident response information suggests room for improvement. Privacy compliance is partial, with a privacy policy present but lacking cookie consent mechanisms despite tracking usage. Overall, the website and domain registration data indicate a legitimate and credible business with a good digital maturity level.

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 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

    • 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

The company operates in the technology sector with a focus on banking and fintech software solutions. Its business model revolves around custom software development for digital asset management, compliance, and financial services. The presence of physical offices in Switzerland and Lithuania, along with a verified LinkedIn profile, supports its market credibility. The company leverages modern web technologies and maintains a professional online presence, targeting fintech startups, banks, and enterprises seeking blockchain and compliance software. No parent or subsidiary companies were identified. The company’s strategic positioning in blockchain and compliance software aligns with growing market demands in fintech and regulatory technology.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and secure form submission practices. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No incident response or security policy information is published, which could impact trust and readiness in case of security incidents. The use of third-party analytics and tracking scripts without a cookie consent mechanism may raise privacy concerns under GDPR. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could be enhanced by adopting additional security headers, publishing security policies, and implementing privacy compliance mechanisms.

Recommendations

  1. Implement comprehensive security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance web security.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR and improve privacy transparency.
  3. Publish a dedicated security policy and incident response contact information to build trust and readiness.
  4. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Consider appointing and publishing Data Protection Officer contact details to strengthen privacy compliance.

Technical notes

Notes

The website is built using the Hugo static site generator, leveraging Bootstrap for responsive design and jQuery for interactivity. It integrates Google Fonts and Adobe Typekit for typography. Analytics are handled via Google Analytics and Google Tag Manager. The site loads multiple JavaScript libraries including Isotope for filtering and Slick for carousels, indicating a modern and interactive user experience. Performance is moderate with asynchronous loading of analytics scripts. Mobile optimization is good, with responsive navigation and layout. SEO is supported by proper meta tags and Open Graph data. No CMS vulnerabilities are apparent due to static site generation. Technical risks include reliance on multiple third-party scripts without visible integrity checks or subresource integrity attributes.
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.
