Risk levelLow

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

The United States Postal Service (USPS) operates the official national postal service website, providing a comprehensive range of mail and shipping services to the general public and businesses. The site offers key functionalities such as package tracking, postage payment and printing, scheduling pickups, ZIP Code lookup, and passport appointment scheduling. USPS holds a strong market position as a government-backed enterprise with extensive reach and brand recognition. Technically, the website employs a modern technology stack including jQuery, RequireJS, Bootstrap, and multiple third-party analytics and advertising pixels. The site is mobile-optimized, accessible, and SEO-friendly, delivering a professional user experience. However, some security best practices such as explicit security headers and a cookie consent mechanism could be improved. From a security perspective, the site enforces HTTPS and uses secure forms, but lacks visible security.txt or vulnerability disclosure pages. The WHOIS data is unavailable, likely due to registry restrictions for government domains, which slightly impacts trust but does not detract from the site's legitimacy given its official branding and content. Overall, USPS.com is a highly professional, secure, and trustworthy government website with minor areas for enhancement in privacy compliance and security transparency. The risk profile is low, and the site effectively serves its broad audience with reliable postal services.

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. 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

  2. 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

USPS.com serves as the digital front for the United States Postal Service, a government entity providing essential mail and shipping services nationwide. The business model is service-oriented, focusing on mail delivery, package shipping, and related customer services. Revenue streams include postage sales, PO Box rentals, and business shipping solutions. The target customers range from individual consumers to small businesses and international shippers. The site integrates with multiple USPS subdomains and partner services, creating a cohesive ecosystem. Growth indicators include digital adoption of services like Click-N-Ship and Informed Delivery. The partnership ecosystem includes government agencies and postal-related services. Strategic observations highlight USPS's role as a critical infrastructure provider with a strong brand and extensive service portfolio.

Security posture

USPS.com demonstrates a mature security posture with mandatory HTTPS, secure form handling, and no exposed sensitive data in the HTML. The presence of multiple tracking and advertising pixels indicates extensive user data collection, which necessitates robust privacy controls. The absence of explicit security headers and vulnerability disclosure mechanisms suggests room for improvement in transparency and defense-in-depth. No critical vulnerabilities or malware indicators were found. Incident response contact information is not publicly visible, which could be enhanced to improve security readiness. Overall, the site balances usability and security well but should strengthen privacy compliance and security communication.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a security.txt file or dedicated vulnerability disclosure page to facilitate responsible reporting and improve transparency.
  3. Introduce a clear cookie consent mechanism to comply with GDPR and other privacy regulations, enhancing user trust.
  4. Provide publicly accessible incident response contact information to improve security communication and readiness.
  5. Regularly audit third-party scripts and tracking pixels to minimize privacy risks and ensure compliance with data protection standards.

Notes

The website uses a robust and modern technology stack including jQuery, RequireJS, and Bootstrap, supporting responsive design and accessibility. Multiple third-party analytics and advertising pixels are integrated, indicating sophisticated marketing and user behavior tracking. The site is well-structured with comprehensive metadata, Open Graph tags, and JSON-LD structured data enhancing SEO and social media integration. Performance is moderate, with potential optimization opportunities in script loading and resource management. The absence of a detected CMS suggests a custom or proprietary platform. Hosting details are not explicitly available, but the site uses HTTPS with strong SSL configuration. Overall, the technical infrastructure supports a high-quality user experience with minor areas for optimization.
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.
