Security report for marriottbonvoy.com

Marriott International, Inc. · Hospitality

Partial score · DNS & email only

75/100

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

The website exhibits a moderate security posture with strong network security and SSL/TLS configurations, but critical gaps in email authentication and compliance frameworks. Notably, the absence of SPF, DKIM, and overall email authentication exposes the business to significant risks such as phishing, spoofing, and email fraud. Medium-level issues in security headers, GDPR, and NIS2 compliance indicate potential vulnerabilities to data privacy breaches and regulatory non-compliance, which could lead to legal and reputational consequences. DNS health is adequate but can be improved by enabling DNSSEC and configuring CAA records to enhance domain integrity and prevent unauthorized certificate issuance. Overall, while core infrastructure security is solid, critical improvements are needed in email security and compliance to mitigate business risks and protect customer trust.

Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

NIS2 outside view
Not assessed
GDPR outside view
Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

2 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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.
  • GDPR outside view: 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.

Technical notes

Notes

The single critical issue identified is the lack of any email authentication mechanisms (no SPF, DKIM, or DMARC), which severely compromises email integrity and can facilitate phishing and spoofing attacks targeting the organization and its clients. High-severity absence of SPF record further exacerbates this risk. Medium-level failures include missing or misconfigured security headers, which can leave the website vulnerable to cross-site scripting and clickjacking. GDPR and NIS2 compliance failures highlight potential gaps in data protection and cybersecurity governance frameworks. DNS health is suboptimal due to DNSSEC not being enabled, reducing domain name resolution security, and missing CAA records increase risk of unauthorized SSL/TLS certificate issuance. SSL/TLS and network security modules scored perfectly, demonstrating strong cryptographic protocols and network defenses are in place.
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.
