Risk levelHigh

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

accilium GmbH is a medium-sized management and strategy consultancy specializing in digital transformation within the mobility, energy, and public sectors. With over 130 consultants across multiple European offices, it holds a strong market position among the top consultancies in the German-speaking region. The company offers services including strategy and innovation, business transformation, data intelligence, and organizational consulting. The website is professionally designed, mobile-optimized, and SEO-friendly, reflecting a mature digital presence. However, the security posture is weakened by the absence of a valid SSL certificate and lack of modern TLS protocol support, which poses risks to data confidentiality and user trust. Privacy compliance is well addressed with GDPR-aligned policies and cookie consent mechanisms. Overall, accilium demonstrates strong business credibility and digital maturity but requires urgent improvements in SSL/TLS security to protect its users 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

12 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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

  3. Network security

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

    • Critical

      Critical Service Exposed: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

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 · found on this site
  • 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

accilium operates in the consulting industry with a focus on digital transformation in energy, transport, and government sectors. Its competitive advantage lies in deep expertise in mobility and energy ecosystems, supported by certifications such as ISO 27001 and TISAX. The business model centers on providing strategic consulting services to enterprises undergoing digital and sustainable transitions. The company targets large enterprises and public sector clients in Europe, leveraging a multi-office presence to serve diverse markets. Growth indicators include recent leadership expansions and strategic promotions. The partnership ecosystem includes LinkedIn and social media engagement, with no suspicious or unrelated domains detected. The company maintains transparency through comprehensive privacy and security policies.

Security posture

The current security maturity level is moderate but compromised by critical issues such as the lack of a valid SSL certificate and disabled TLS protocols, which are fundamental for secure communications. While the company holds ISO 27001 and TISAX certifications indicating a formal security management framework, the website's technical security implementation is lacking. No major vulnerabilities like Heartbleed or POODLE were detected, and cookie consent mechanisms are in place. However, the absence of HTTPS and modern security headers reduces protection against interception and man-in-the-middle attacks. Incident response information is not publicly available, which could hinder timely breach management. Overall, the security culture appears formalized but requires technical remediation to align with best practices.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate immediately to enable HTTPS and protect user data.
  2. Enable and enforce modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated versions.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Enable OCSP stapling to improve certificate revocation checking performance and security.
  5. Publish incident response contact information and vulnerability disclosure policies to enhance transparency and readiness.

Technical notes

Notes

The website is built on WordPress CMS using modern plugins and themes such as Yoast SEO Premium, Elementor, Blocksy, and Complianz GDPR Cookie Consent. It integrates Google Analytics, Google Tag Manager, Hotjar, and Google AdSense for analytics and marketing. The hosting provider is identified as kasserver.com. Performance is moderate with room for optimization. The site is mobile-optimized and accessible with good SEO practices. However, the lack of HTTPS and TLS support is a significant technical risk. The site uses jQuery and Slick Slider for UI components. Overall, the technical infrastructure supports a professional consulting business but requires urgent security upgrades.
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.
