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

ICON Wirtschaftstreuhand GmbH is a medium-sized Austrian professional services firm specializing in tax consulting, auditing, and international tax expertise. The company holds a strong market position, being ranked first in sustainability and machinery & plant engineering consulting by INDUSTRIEMAGAZIN in 2025. Their business model focuses on delivering comprehensive tax and audit services through nine specialized service lines supported by a global network and membership in WTS Global. The website reflects a professional and consistent brand image targeting businesses and private clients with international tax needs. Technically, the site is built on TYPO3 CMS, served via Apache and Amazon CloudFront CDN, and uses modern web technologies including Font Awesome and Google Tag Manager. However, the site lacks a valid SSL certificate and does not serve content over HTTPS, which is a critical security shortcoming despite the presence of strong security headers and a content security policy. Privacy and cookie policies are present and GDPR compliant, with consent mechanisms implemented. Contact information is comprehensive and clearly presented. Overall, the site is well-designed and content-rich but requires urgent security improvements to enable HTTPS and strengthen its security posture.

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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  2. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

ICON Wirtschaftstreuhand GmbH operates in the finance sector, providing tax advisory and auditing services with a focus on international clients. Their competitive advantage lies in their industry-specific expertise, especially in sustainability and machinery sectors, and their global network affiliation. The business model is service-oriented, targeting corporate and private clients requiring complex tax solutions. The company maintains partnerships with recognized entities such as WTS Global and uses external platforms for seminars and webinars, indicating a strong ecosystem. Growth indicators include industry recognition and active content marketing through news, seminars, and expert testimonials. The website supports lead generation and client engagement through newsletters and a job portal, reflecting a mature digital presence.

Security posture

The website demonstrates moderate security maturity with several best practices implemented, including security headers like X-Content-Type-Options, X-Frame-Options, Content Security Policy, and X-XSS-Protection. However, the absence of a valid SSL certificate and lack of HTTPS delivery severely undermine the security posture, exposing users to risks such as data interception and man-in-the-middle attacks. No vulnerabilities like Heartbleed or POODLE were detected, and no vulnerable libraries were identified. Incident response and security policy information are not publicly available, which could be improved to enhance transparency and trust. The site does not implement OCSP stapling or session resumption, which could improve performance and security. Overall, the security posture is weak due to missing HTTPS, requiring immediate remediation.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and configure strong cipher suites.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Publish a clear security policy and incident response contact information to increase transparency.
  5. Regularly audit and update third-party scripts and tracking tools to ensure privacy compliance and security.

Technical notes

Notes

The website is powered by TYPO3 CMS with PHP 8.1.32 on an Apache server, delivered via Amazon CloudFront CDN. It uses modern front-end technologies including Font Awesome 6 Pro and Google Tag Manager for analytics and marketing. The site is mobile optimized with responsive design and good accessibility features. SEO is well addressed with proper meta tags and Open Graph data. Performance metrics are not available, but the use of CDN and optimized images suggests moderate to good performance. The lack of HTTPS is a critical technical debt. The site uses multiple external domains for analytics, social media, and marketing integrations, which are standard for professional websites but require careful privacy management.
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.
