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

Keystone Advisers is an established independent investment banking firm founded in 2005, specializing in mergers, acquisitions, divestitures, capital raising, and financing advisory services primarily in the Baltic region. The company serves medium-sized enterprises and international clients, leveraging over 20 years of market experience and a strong professional team. Their digital presence is built on WordPress with multilingual support, optimized for desktop and mobile users, and includes SEO best practices. However, the website lacks critical privacy and cookie policies, which impacts compliance and user trust. Security posture is adequate with HTTPS enabled but could be improved by adding security headers and incident response information. Overall, Keystone Advisers presents a professional and trustworthy business profile with room for enhancing privacy and security transparency.

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.

Priority findings

10 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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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"

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

      Missing X-Frame-Options header

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

The company holds a strong market position in the Baltic financial advisory sector with a clear focus on M&A and financing solutions. Their business model revolves around providing specialized consulting services to medium-sized companies, supported by a network of regional offices in Estonia, Latvia, Lithuania, and Israel. The presence of multiple regional domains and professional contact details indicates a well-structured organization. The partnership with a web development firm suggests a commitment to maintaining a quality digital presence. Growth indicators include a long operational history and a portfolio of notable clients. The company could benefit from expanding its compliance documentation and security disclosures to strengthen client confidence.

Security posture

Keystone Advisers maintains a secure website with HTTPS and no visible exposure of sensitive data. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces the overall security robustness. There is no public vulnerability disclosure or incident response contact information, which limits transparency and preparedness for security incidents. The use of common WordPress plugins necessitates regular updates to mitigate vulnerabilities. Privacy compliance is weak due to missing privacy and cookie policies, which could expose the company to regulatory risks. Enhancing these areas would improve the security maturity and trustworthiness of the website.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to improve protection against common web attacks.
  3. Publish a vulnerability disclosure policy or security.txt file to demonstrate transparency and readiness.
  4. Provide incident response contact information (e.g., security@ or abuse@ email addresses) to facilitate reporting of security issues.
  5. Ensure all WordPress plugins and themes are regularly updated to minimize vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS using the Avia Framework and includes plugins such as Yoast SEO and WPML for multilingual support. The technology stack is modern and widely supported, with jQuery and Google Fonts integrated. Performance is moderate with good mobile optimization and basic accessibility features. SEO is well addressed with proper meta tags and structured data in JSON-LD format. Hosting details are not explicitly identified. The site uses Google Analytics for user tracking but lacks cookie consent mechanisms, which could be improved for privacy compliance. Overall, the technical implementation supports a professional and functional website but could benefit from enhanced security and privacy features.
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.
