PartnerStack is a leading SaaS platform specializing in partner relationship management (PRM) and partner ecosystem scaling for B2B SaaS companies. The company offers a comprehensive platform that enables businesses to recruit, activate, track, and reward partners including affiliates, influencers, and resellers. Positioned as the #1 partner ecosystem platform, PartnerStack serves over 600 companies and boasts a network of more than 115,000 active partners. Their services focus on automating partner operations, commission management, and providing actionable insights to optimize partner performance. Technically, PartnerStack's website is built on modern web technologies including Webflow CMS, integrated with analytics and marketing tools such as Segment, Google Tag Manager, HubSpot Forms, and Wistia for video content. The site is hosted and registered via Cloudflare, ensuring robust DNS and SSL configurations. The platform demonstrates excellent mobile optimization, accessibility, and SEO practices, contributing to a fast and user-friendly experience. From a security perspective, the website enforces HTTPS, employs security headers, integrates reCAPTCHA for form protection, and uses fraud detection services like Sift. However, there is room for improvement in publishing explicit security policies, incident response contacts, and vulnerability disclosure mechanisms. No critical vulnerabilities or exposed sensitive data were detected. Overall, PartnerStack presents a mature, professional, and trustworthy online presence with strong business credibility and technical maturity. The risk profile is low, with recommendations focusing on enhancing transparency around security policies and further hardening DNS security.

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 competitive B2B SaaS partner management market, leveraging a unique marketplace model that connects SaaS vendors with a large network of partners. Their business model is subscription-based SaaS, targeting mid to large-sized SaaS companies seeking to scale partner-driven revenue streams. The company differentiates itself through multi-channel partner support (affiliates, co-sell, influencers) and automation capabilities that reduce manual partner management overhead. Strategic partnerships and a growing partner network contribute to their market leadership. The company’s content marketing, research reports, and customer testimonials reinforce their thought leadership and customer trust.

Security posture

The security posture of PartnerStack's website is strong, with HTTPS enforced and multiple security headers implemented. The use of Google reCAPTCHA and integration with Sift for fraud detection indicate proactive measures against abuse and fraudulent activity. However, the absence of publicly available security policies, incident response contacts, and vulnerability disclosure programs suggests an opportunity to improve transparency and readiness. No signs of outdated or vulnerable libraries were found. Overall, the site follows best practices for web security but could enhance its compliance and incident management documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure or bug bounty program to encourage responsible reporting.
  4. Enable DNSSEC to improve domain name system security and prevent DNS spoofing.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.

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.
