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

5 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.

    • 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

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

PartnerStack operates in the technology sector, targeting B2B SaaS companies seeking to scale their partner programs. Its business model revolves around providing a SaaS platform that automates partner recruitment, onboarding, tracking, commission payments, and program optimization. The company leverages a large partner network and marketplace to boost channel revenue for clients. Strategic advantages include a comprehensive feature set, strong customer validation, and integration with popular marketing and analytics tools. Growth indicators include a broad customer base (600+ companies), active partner network (115,000+ partners), and ongoing product updates and events. The partnership ecosystem is a core asset, enabling scalable revenue growth for clients.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA to prevent abuse, and integration of fraud detection services (Sift) within the PartnerStack platform. Security headers are implied though not explicitly listed in the HTML snapshot. No sensitive data exposure or vulnerable libraries were detected. However, the absence of publicly accessible security policies, incident response contacts, or vulnerability disclosure mechanisms indicates room for improvement in transparency and compliance. GDPR compliance is not explicitly documented, and no cookie consent mechanism was found. Overall, the security posture is strong technically but lacks some governance documentation.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy accessible from the homepage.
  2. Implement a cookie consent mechanism to comply with GDPR and other privacy regulations.
  3. Add a dedicated security policy and incident response page with contact information.
  4. Introduce a vulnerability disclosure or security.txt file to encourage responsible reporting.
  5. Explicitly set and document all security headers to enhance security posture and transparency.

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.
