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

Omnisend is a specialized ecommerce-focused email and SMS marketing automation platform designed to help ecommerce brands increase revenue efficiently through automation, segmentation, and multi-channel campaigns. The company positions itself as a nimble and user-friendly SaaS solution with strong integrations to major ecommerce platforms such as Shopify, WooCommerce, and BigCommerce. The website demonstrates a mature digital presence with professional design, comprehensive content, and strong branding consistency. Technically, the site leverages WordPress CMS with modern JavaScript libraries, analytics, and consent management tools, indicating a well-maintained infrastructure. Security posture is good with HTTPS enforced and cookie consent implemented, though explicit security headers and a public security policy are absent. WHOIS data is not publicly available, likely due to privacy protection, which slightly reduces trust but is common for SaaS businesses. Overall, the site is professional, secure, and compliant with privacy regulations, targeting ecommerce marketers and businesses seeking marketing automation solutions.

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

Omnisend operates in the competitive ecommerce marketing automation sector, offering a SaaS platform that integrates email, SMS, and push notifications to drive sales and customer engagement. Its business model is subscription-based, targeting small to medium ecommerce brands. The company leverages partnerships with major ecommerce platforms and maintains a strong ecosystem of integrations and apps. The website content and social media presence reflect a growth-oriented company with a focus on ease of use and automation. The lack of public WHOIS data is offset by the brand's established market presence and professional online footprint. Revenue streams likely include tiered subscription plans and add-on services. The company emphasizes AI-driven features and data empowerment to differentiate itself in the market.

Security posture

The website enforces HTTPS and uses modern security and analytics tools such as Sentry and Cookiebot for error tracking and consent management. However, explicit security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not visibly implemented, which could be improved to enhance protection against common web attacks. There is no publicly available security policy or incident response information, and no vulnerability disclosure or security.txt file was found. The site appears free of exposed sensitive data or vulnerable libraries based on the provided content. Privacy compliance is strong with GDPR-aligned cookie consent and privacy policy. Overall, the security posture is good but could benefit from enhanced transparency and additional security headers.

Recommendations

  1. Implement and publish explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Create and make accessible a dedicated security policy and incident response page to improve transparency and trust.
  3. Publish a vulnerability disclosure policy and security.txt file to facilitate responsible reporting of security issues.
  4. Enhance visibility of data protection officer contact information and relevant certifications to demonstrate compliance and security culture.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included and maintain optimal performance.

Notes

The website is built on WordPress CMS with a custom theme optimized for ecommerce marketing. It uses modern JavaScript libraries including Swiper.js for sliders, Wistia for video embedding, and integrates with Google Tag Manager for analytics and tracking. Cookiebot is used for cookie consent management, indicating GDPR compliance. The site loads efficiently with preconnect and preload hints for fonts and scripts, suggesting good performance optimization. Mobile responsiveness and accessibility are well addressed. The presence of Visual Website Optimizer indicates active A/B testing and conversion optimization efforts. No hosting provider details were found, but the infrastructure appears robust and professionally managed. Opportunities exist to improve security headers and incident response transparency.
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.
