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

Retention Science is a medium-sized SaaS company specializing in AI-driven email and SMS marketing automation for ecommerce businesses. Their platform integrates customer data and uses predictive analytics to optimize marketing campaigns, helping clients increase engagement and sales. The website is professionally designed using modern technologies like React and Gatsby, with good SEO and accessibility features. However, a critical security issue is the absence of a valid SSL certificate and HTTPS, which significantly impacts the site's security posture. Privacy compliance is well addressed with a comprehensive privacy policy and cookie consent mechanism. Overall, the company presents a credible and trustworthy business front but must urgently address its SSL/TLS configuration to ensure secure communications and protect user data.

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

4 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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

Retention Science targets ecommerce businesses seeking to enhance customer engagement and retention through AI-powered marketing automation. Their business model is subscription-based SaaS, leveraging integrations with leading ecommerce platforms. The company has a strong market presence with hundreds of brand partners and extensive customer reach. Key competitive advantages include AI-driven personalization, multi-channel marketing (email and SMS), and rich data reporting. The website highlights customer testimonials and partner logos as trust signals. The company maintains transparency with terms, privacy, and vulnerability disclosure pages, supporting regulatory compliance and customer trust.

Security posture

The website's security posture is weak due to the lack of a valid SSL certificate and absence of HTTPS, exposing users to potential data interception risks. No security headers are present, and modern TLS protocols are not enabled. While SPF and DMARC DNS records are configured correctly, DNSSEC and CAA records are missing, reducing DNS security. Cookie consent is managed properly via Cookiebot, indicating good privacy practices. No explicit security policy or incident response contacts are found, which could hinder timely handling of security incidents. The vulnerability disclosure page exists but lacks a security.txt file. Immediate remediation of SSL/TLS and security headers is recommended to elevate security maturity.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS site-wide.
  2. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated ones.
  4. Add DNSSEC and CAA DNS records to enhance DNS security.
  5. Publish a security.txt file to complement the existing vulnerability disclosure page.
  6. Establish and publish a formal security policy and incident response contact information.
  7. Regularly audit third-party scripts and dependencies for vulnerabilities.
Technical notes

Notes

The website is built using React and Gatsby, hosted on AWS infrastructure as inferred from DNS nameservers. It uses Google Analytics and Optimizely for analytics and experimentation, and Cookiebot for cookie consent management. The site has moderate load time (~6.4 seconds) and a moderate number of resources (48). Mobile optimization and accessibility are good, with semantic HTML and ARIA roles present. SEO is supported by comprehensive meta tags, Open Graph, and JSON-LD structured data. However, the lack of HTTPS and SSL certificate is a major technical risk. Performance can be improved by optimizing resource loading and reducing page size. Overall, the technical stack is modern and well-implemented but requires urgent security upgrades.
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.
