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.

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

Sezzle operates in the competitive buy now, pay later market, targeting consumers who seek flexible payment options without interest fees. Its business model revolves around installment payments and credit building, appealing to younger demographics and financially conscious shoppers. The company leverages partnerships with merchants to integrate its payment solutions, expanding its market reach. Sezzle's strong brand reputation is reinforced by high customer ratings and active social media presence. The company’s growth is supported by modern technology adoption and strategic marketing through analytics and review platforms. No parent or subsidiary companies were identified, indicating a focused operational structure.

Security posture

Sezzle demonstrates a mature security posture with HTTPS enforced site-wide and implementation of key security headers such as Content-Security-Policy and Strict-Transport-Security. No critical vulnerabilities or exposed sensitive information were detected in the website content. However, the absence of a publicly available security policy or incident response page suggests room for improvement in transparency and preparedness communication. Privacy policies are comprehensive and GDPR compliant, indicating strong data protection practices. The use of reputable third-party analytics and review services is balanced with privacy considerations. Overall, the security maturity is high but could benefit from enhanced disclosure of security governance.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency around data retention policies and user privacy controls.
  5. Continue monitoring and updating third-party libraries and scripts to mitigate potential vulnerabilities.

The site uses optimized fonts and images, contributing to performance and SEO.

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.
