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

Simpler.so is an e-commerce focused SaaS platform offering a streamlined checkout solution that integrates multiple payment options to help merchants save on fees and increase sales. The website presents a professional and modern design built on Webflow, leveraging various third-party marketing and analytics tools such as Google Tag Manager, Facebook Pixel, LinkedIn Insight Tag, and Plausible Analytics. The presence of a comprehensive cookie consent mechanism indicates attention to privacy compliance, although no explicit privacy policy or terms of service pages were detected in the provided content. Security posture is solid with HTTPS enforced and no visible vulnerabilities, but could be improved by adding explicit security headers and publishing security policies. The lack of WHOIS registration data is a concern for domain legitimacy and reduces overall trustworthiness. Overall, the site is functional and business-focused but would benefit from enhanced transparency and contact information.

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

1 finding rated critical or high. Fix these first.

  1. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

The company targets e-commerce merchants seeking an easy-to-integrate checkout solution that supports multiple payment methods and reduces transaction fees. The business model is SaaS-based, focusing on checkout optimization and payment processing partnerships, notably with Stripe. The website's integration with marketing and analytics platforms suggests a data-driven approach to customer acquisition and retention. The absence of detailed company information and contact details limits external validation but the technology stack and partner domains indicate a legitimate operation within the e-commerce technology sector.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and no exposed sensitive data. Cookie consent is implemented with granular controls, supporting GDPR compliance. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security or incident response policies represent gaps. No vulnerabilities or malware indicators were found in the analyzed content. The WHOIS data absence is a negative factor for trust but does not directly indicate a security risk. Enhancing transparency and security documentation would improve the security posture.

Recommendations

  1. Publish a clear and accessible privacy policy and terms of service pages.
  2. Add explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide visible and verified contact information including support emails and phone numbers.
  4. Establish and publish an incident response policy with dedicated security contact channels.
  5. Verify and update WHOIS registration data to improve domain legitimacy and trust.

Technical notes

Notes

The website is built on Webflow CMS and uses a modern tech stack including Google Tag Manager, Facebook Pixel, LinkedIn Insight Tag, Cookiebot for consent management, and Weglot for multilingual support. Hosting is via Webflow's CDN, providing moderate performance and good mobile optimization. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but present. The site uses multiple third-party scripts for analytics and marketing, which increases tracking but supports business intelligence. No technical debt or critical performance issues were detected in the provided content.
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.
