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

Constant Contact is a well-established digital and email marketing platform primarily serving small to medium-sized businesses. It offers a SaaS subscription model focused on email marketing, online marketing campaigns, and marketing automation. The company is positioned as a leader in the email marketing industry and is a subsidiary of Endurance International Group. The website reflects a professional and consistent brand image with clear messaging and a strong call to action for free trials. Technically, the website is built using modern frameworks such as Gatsby and React, with integrations for consent management (Cookiebot), A/B testing (Optimizely), and video hosting (Wistia). The site is optimized for performance, mobile responsiveness, and accessibility, indicating a mature digital infrastructure. From a security perspective, the site enforces HTTPS, implements key security headers, and uses a cookie consent mechanism, demonstrating good security hygiene. However, explicit security policies, incident response information, and vulnerability disclosure mechanisms are not publicly available, which could be improved to enhance transparency and trust. Overall, the website is safe, professional, and trustworthy, with no indications of malicious content or blocking mechanisms. The lack of WHOIS data limits domain registration insights but does not detract from the site's legitimacy. Strategic recommendations include publishing security policies and vulnerability disclosure details to strengthen security posture and compliance visibility.

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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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

  3. 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

      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

Constant Contact operates in the technology sector, focusing on digital marketing solutions for small and medium businesses. Its competitive advantage lies in its established brand, comprehensive marketing tools, and integration capabilities. The business model is subscription-based SaaS, generating revenue through tiered plans and add-on services. The target customers are marketers and small business owners seeking effective email and online marketing solutions. The company benefits from its parent company Endurance International Group's resources and market reach. Growth indicators include continuous platform enhancements and marketing partnerships. The ecosystem includes integrations with analytics, consent management, and video hosting providers, supporting a robust marketing technology stack.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, modern security headers, and cookie consent compliance. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program indicates room for improvement in transparency and preparedness. Compliance with GDPR is indicated through consent mechanisms and privacy policy content. The site lacks explicit contact channels for security incidents or abuse reporting, which is a gap in incident response readiness. Overall, the security posture is solid but could be enhanced by formalizing and publishing security governance documents.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Enhance transparency on certifications and compliance frameworks relevant to data protection.
  4. Provide explicit contact channels for security incidents and abuse reporting.
  5. Regularly review and update privacy and cookie policies to maintain GDPR and other regulatory compliance.

Opportunities exist to enhance technical documentation and security 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.
