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

One Square Advisors is a specialized financial advisory firm based in Germany, focusing on financial restructuring, insolvency consulting, M&A, trustee services, real estate, and bond services. The company positions itself as an expert partner for special financial situations, targeting businesses and financial professionals seeking tailored solutions. The website is professionally designed, primarily in German, and provides detailed descriptions of its key services, reflecting a niche market position with a small company size and a founding year of 2008. Technically, the website is built on WordPress using popular plugins such as WPBakery Page Builder and Slider Revolution. The infrastructure is moderate in performance with good mobile optimization and basic accessibility features. Hosting and domain registration are consistent with the company's German location, with SSL enabled and domain transfer protections in place. However, DNSSEC is not enabled, and some security headers are missing, indicating room for improvement in security hardening. From a security perspective, the site enforces HTTPS and implements a cookie consent mechanism, showing awareness of privacy compliance. However, it lacks a published privacy policy, terms of service, security policy, incident response contacts, and vulnerability disclosure mechanisms, which are important for regulatory compliance and trust. No critical vulnerabilities or malicious content were detected, but the absence of DNSSEC and security.txt files are notable gaps. Overall, the website is trustworthy and professional but would benefit from enhanced privacy and security disclosures to improve compliance and user trust. Strategic recommendations include publishing comprehensive privacy and security policies, enabling DNSSEC, adding security headers, and establishing a vulnerability disclosure process.

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

7 findings rated critical or high. Fix these first.

  1. 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: 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)

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  2. 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"

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

One Square Advisors operates in the finance sector with a focus on financial restructuring and insolvency advisory, serving a specialized market segment. Their business model revolves around providing expert consultancy and tailored financial solutions for complex situations. The company leverages its decades of combined expertise to differentiate itself in a competitive market. The website's content and LinkedIn presence support a credible professional image. Revenue streams likely derive from consulting fees and trustee services. The firm targets corporate clients and financial institutions, emphasizing trust and experience. No parent or subsidiary companies were identified, indicating an independent operation. The company maintains a focused partnership ecosystem, including LinkedIn for professional networking. Growth indicators are not explicit but the domain age and content quality suggest stable operations.

Security posture

The security maturity of the website is moderate. HTTPS is properly implemented, ensuring encrypted communications. The domain status clientTransferProhibited adds protection against unauthorized domain transfers. However, the absence of DNSSEC leaves the domain vulnerable to DNS spoofing attacks. Security headers such as Content-Security-Policy and X-Content-Type-Options are not detected, which could mitigate certain web-based attacks. No exposed sensitive data or vulnerable libraries were identified in the analysis. The site uses standard WordPress plugins, which require regular updates to prevent vulnerabilities. Privacy compliance is partial, with cookie consent but no privacy policy or terms of service. Incident response readiness is not evident due to lack of published contacts. Overall, the security posture is adequate for a small professional site but requires enhancements to meet higher compliance standards like GDPR fully.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve GDPR compliance and user trust.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Implement additional security headers such as Content-Security-Policy and X-Content-Type-Options to harden the website against common attacks.
  4. Create and publish a security policy and incident response contact information to demonstrate security maturity and readiness.
  5. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.

Technical notes

Notes

The website is built on a WordPress CMS platform using WPBakery Page Builder and Slider Revolution plugins, indicating a modern but common technology stack. It uses jQuery and other standard JavaScript libraries. The site loads CSS and JS assets from its own domain, minimizing third-party dependencies except for Google Fonts. Hosting appears stable with a German registrar and DNS servers. Performance is moderate, with no explicit speed optimizations detected but good mobile responsiveness. Accessibility is basic, with room for improvement in semantic markup and ARIA attributes. SEO is supported by proper meta tags and structured links. The site uses a custom child theme with embedded fonts, showing some customization. Overall, the technical infrastructure is solid for a small business website but could benefit from performance and accessibility 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.
