44/100

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

untermStrich Software GmbH is a technology company specializing in SaaS-based office management and controlling software tailored for architects and engineers. The company has a strong market presence with approximately 87,000 users worldwide and operates in multiple countries including Austria, Germany, and the USA. Their flagship product, untermStrich X4, offers comprehensive tools for project management, electronic invoicing, CRM, and document management, targeting architectural and engineering firms. The website demonstrates a high level of digital maturity with professional design, structured data, and SEO optimization. However, the current lack of a valid SSL/TLS certificate and disabled HTTPS protocols represent a critical security vulnerability that must be addressed promptly. Privacy and cookie policies are well implemented and GDPR compliant, enhancing user trust. Overall, untermStrich presents a credible and professional business with a solid technical infrastructure but requires immediate improvement in 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

1 finding rated critical or high. Fix these first.

  1. 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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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, focusing on software solutions for the architecture and engineering industries. Their business model includes both software licensing and SaaS subscriptions, providing flexibility to customers. The website content and structured data indicate a medium-sized enterprise with a consistent brand and strong trust signals such as ISO 27001 certification and extensive customer base. Partnerships with organizations like aia.de further strengthen their market position. The company emphasizes customer support and continuous product development, with multiple contact channels and a customer portal. Growth indicators include daily new community members and international expansion. The marketing ecosystem leverages HubSpot and Google Tag Manager for lead generation and analytics.

Security posture

The website employs several security headers including HSTS, X-Content-Type-Options, X-Frame-Options, and X-XSS-Protection, which are positive indicators. However, the absence of a valid SSL certificate and disabled TLS protocols severely undermine the security posture, exposing users to risks such as data interception and man-in-the-middle attacks. No incident response or vulnerability disclosure information is found, which could be improved to enhance transparency and readiness. The hosting environment and server details are limited but appear standard. Overall, the security maturity is moderate but requires urgent remediation of SSL/TLS issues to meet industry best practices and compliance requirements.

Recommendations

  1. Obtain and install 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 and publish a vulnerability disclosure policy or security.txt file to improve transparency.
  4. Provide explicit incident response contact information to facilitate security communications.
  5. Regularly audit and update security headers and server configurations to maintain compliance.

Technical notes

Notes

The website is built on WordPress 6.8.1 using the Flatsome theme and several plugins including Rank Math SEO, WP Rocket for performance optimization, and Complianz for GDPR cookie consent management. It uses jQuery 3.7.1 and integrates HubSpot forms for marketing and lead capture. The site is optimized for mobile with responsive design and accessibility features. Performance metrics are missing, indicating a potential gap in monitoring. Hosting appears to be on an Apache server with a single IPv4 address. The site uses structured data (JSON-LD) extensively for SEO and rich snippets. The main technical risk is the invalid SSL configuration, which impacts user trust and security compliance.
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.
