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

      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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 22 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

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, focusing on SaaS partner relationship management. Its business model revolves around providing a platform that enables SaaS companies to scale revenue through diverse partner types such as affiliates, resellers, and influencers. The company leverages a large partner network and marketplace to boost channel revenue. Its competitive advantage lies in its comprehensive platform features, ease of use, and strong partner engagement tools. Revenue streams likely include subscription fees and commissions. The target customers are SaaS vendors and partners seeking to grow through partnerships. Growth indicators include a large customer base (600+ companies) and an extensive active partner network (115,000+). The company emphasizes automation, transparency, and partner experience to sustain growth.

Security posture

The website exhibits a good security maturity level with HTTPS enforced and domain registration protections like clientTransferProhibited status. Use of Cloudflare DNS and integration of Sentry for error monitoring enhance security monitoring capabilities. However, the absence of DNSSEC and explicit security headers such as Content-Security-Policy and X-Frame-Options represent gaps that could be exploited. No exposed sensitive data or vulnerable libraries were detected. Privacy policies and incident response contacts are not publicly available, indicating potential compliance gaps with GDPR and NIS2. The site uses cookie consent mechanisms, but overall privacy compliance could be improved. The security culture appears proactive with fraud detection mentioned in platform features. Incident response readiness and vulnerability disclosure are not evident.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement and publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  4. Publish a security policy and provide clear incident response contact channels (e.g., security@ or abuse@ emails).
  5. Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting and enhance security posture.

Overall, the technical infrastructure supports a scalable and secure SaaS platform.
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.
