59/100

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

ATP architekten ingenieure is a well-established European architecture and engineering firm specializing in integrative planning and sustainable building solutions using Building Information Modeling (BIM). With over 1,500 employees and 14 locations across Europe, the company holds a strong market position as a BIM pioneer and leader in sustainable architecture. The website reflects a high level of professionalism, comprehensive project portfolios, and active engagement with clients through social media and contact forms. Technically, the site uses modern frameworks like Astro and is hosted on Netlify, but suffers from a critical security issue due to an invalid or missing SSL certificate, which undermines the security posture. Privacy and cookie policies are present and GDPR compliant, supporting good privacy practices. Overall, the site is content-rich and user-friendly but requires urgent security improvements to protect user data and enhance trust.

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 Real Estate sector, focusing on architecture, engineering, consulting, and integrative planning services. Founded in 1951, ATP architekten ingenieure has grown into an enterprise-scale firm with a broad European footprint. Their business model centers on delivering sustainable and innovative building projects, leveraging BIM technology. The firm targets clients interested in emission-free, future-proof buildings and offers a wide range of services including general planning, consulting, and special research projects. The website's detailed project showcases and multiple location pages indicate a mature and diversified portfolio. The presence of social media links and a contact form suggests active client engagement and marketing efforts. No evidence of payment processing or e-commerce was found, consistent with a professional services business.

Security posture

The website's security posture is weakened by the absence of a valid SSL certificate and lack of enabled TLS protocols, which is a critical vulnerability exposing users to potential data interception. While some security headers like HSTS are present, they are ineffective without proper HTTPS configuration. No advanced security frameworks or incident response contacts are evident. The site does not implement DNSSEC or CAA records, missing opportunities to enhance domain security. Forms include GDPR consent checkboxes, indicating awareness of data protection requirements. Overall, the security maturity is basic and requires immediate remediation of SSL issues and enhancement of transport security to meet modern standards.

Recommendations

  1. Renew and correctly install a valid SSL certificate to enable HTTPS and protect user data.
  2. Enable TLS 1.2 or TLS 1.3 protocols and disable insecure protocols to improve encryption.
  3. Implement OCSP stapling and session resumption to optimize SSL performance and security.
  4. Add DNSSEC and CAA DNS records to strengthen domain security and certificate issuance control.
  5. Publish a security policy and incident response contact information to improve transparency and readiness.
Technical notes

Notes

The website is built using the Astro framework and hosted on Netlify, indicating a modern and scalable infrastructure. It uses Partytown to offload third-party scripts, improving performance. Google Tag Manager is integrated for analytics and marketing. The site is mobile optimized with responsive design and good accessibility features. SEO is supported by proper meta tags, Open Graph tags, and structured JSON-LD data describing images and projects. However, performance metrics are missing or zero, suggesting incomplete data collection or monitoring. The invalid SSL certificate is a major technical flaw impacting security and user trust. Overall, the technical implementation is modern and well-structured but requires security fixes and performance monitoring enhancements.
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.
