Security score

Risk levelMedium

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

LeanLinking is a technology company offering a SaaS platform focused on supplier relations and negotiation management. Their solution targets procurement teams aiming to improve supplier visibility, automate compliance, and strengthen supplier relationships. The website is professionally designed using Webflow, with good mobile optimization and clear navigation. The technical infrastructure includes modern analytics and marketing tools such as Google Analytics, Microsoft Clarity, and LinkedIn Insight Tag, integrated via Google Tag Manager. The site enforces HTTPS and provides a comprehensive cookie consent mechanism compliant with GDPR. However, the absence of WHOIS data raises concerns about domain registration legitimacy. No explicit privacy policy or terms of service pages were found, and contact information is limited to a contact form without direct emails or phone numbers. Overall, the security posture is good but could be improved by adding security headers and explicit security policies.

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

4 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      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

      What to do: Implement a Content-Security-Policy appropriate for your application

      • 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';…

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 13 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

LeanLinking positions itself as a trusted supplier management solution across multiple industries, focusing on procurement efficiency and compliance automation. Their business model is SaaS-based, targeting medium to large enterprises needing supplier data consolidation and negotiation tools. The website content and branding are consistent and professional, with trust signals including detailed cookie policies and third-party analytics. The lack of WHOIS data and direct contact details slightly reduce business credibility. The company leverages partnerships with major platforms like Microsoft and Google for analytics and marketing, indicating a mature digital ecosystem. Growth potential is supported by clear calls to action for demos and contact, but transparency on company registration and security policies could be enhanced.

Security posture

The website uses HTTPS with a presumably strong SSL configuration, and implements a detailed cookie consent banner supporting GDPR compliance. Tracking and marketing scripts from reputable providers are used responsibly with user consent. However, no explicit security headers were detected, and no security or incident response policies are published. The absence of a security.txt file or vulnerability disclosure policy limits transparency for security researchers. No exposed sensitive data or vulnerable libraries were identified. The overall security posture is good but could be strengthened by publishing security policies, adding security headers, and providing incident response contact channels.

Recommendations

  1. Add and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish explicit privacy policy and terms of service pages separate from the cookie policy to improve transparency and compliance.
  3. Provide direct company contact emails and phone numbers on the website to improve business credibility and user trust.
  4. Implement a security.txt file and vulnerability disclosure policy to facilitate responsible security reporting.
  5. Verify and publish domain WHOIS information to confirm domain legitimacy and improve trustworthiness.

Technical notes

Notes

The website is built on Webflow, leveraging modern front-end technologies and third-party integrations for analytics and marketing. Google Tag Manager is used to manage multiple tracking scripts including Google Analytics, Microsoft Clarity, and LinkedIn Insight Tag. The site is mobile optimized with good accessibility features such as focus-visible outlines and keyboard navigation support. Performance is moderate with optimized images and asynchronous script loading. However, no hosting provider information was detected, and no server-side security headers were identified. The technical implementation is solid but could benefit from enhanced security configurations and more transparent business information.
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.
