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

3 findings 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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

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

  • Security headers: did not complete in this scan.
  • 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

MassMutual operates in the finance sector with a focus on insurance and retirement solutions. Its business model centers on mutuality, providing products directly to consumers and businesses. The company maintains a strong brand presence with multiple specialized domains serving different customer segments such as financial professionals and institutional clients. The website content and tools like calculators support customer engagement and financial planning. The company’s market position is reinforced by comprehensive service offerings and a large enterprise scale. Partnerships and related domains indicate a broad ecosystem supporting diverse financial needs.

Security posture

The website demonstrates a mature security posture with HTTPS, multiple security headers, and use of monitoring tools like New Relic. Sensitive input masking and session replay controls are implemented to protect user data. However, the absence of a publicly accessible vulnerability disclosure policy or security.txt file and lack of explicit incident response contacts are areas for improvement. No obvious vulnerabilities or exposed sensitive data were detected. The security score is high but could be enhanced by increasing transparency and formalizing incident response communications.

Recommendations

  1. Publish a dedicated vulnerability disclosure or security.txt file to improve transparency and encourage responsible reporting.
  2. Provide explicit incident response contact information such as security@ or abuse@ email addresses on the website.
  3. Enhance visibility of security certifications or compliance attestations to strengthen trust.
  4. Regularly review and update privacy and cookie policies to maintain GDPR and other regulatory compliance.
  5. Continue investing in performance and accessibility improvements to maintain excellent user experience.

Technical notes

Notes

The website is built on a modern React framework with integration of advanced monitoring and analytics tools including New Relic and Tealium. It uses Sitecore CMS, indicating enterprise-grade content management. Performance optimizations and mobile responsiveness are evident. The use of multiple external APIs and libraries such as YouTube and Vimeo players enriches content delivery. Technical debt appears low with current best practices in place. Opportunities exist to further enhance security transparency and incident readiness. Hosting details are not explicitly identified but likely enterprise-grade given the scale and technology stack.
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.
