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

The Thrift Savings Plan (TSP) website serves as the official online portal for the U.S. federal government's retirement savings and investment plan for federal employees and uniformed service members. Established by Congress in 1986, the TSP offers retirement savings options similar to private sector 401(k) plans. The website provides comprehensive information on plan management, fund options, performance, and withdrawal processes, targeting federal employees and service members. It maintains a strong market position as the authoritative source for TSP-related information and services. Technically, the website is built using modern web technologies including Jekyll as a static site generator, USWDS for design consistency, and integrates Google Analytics and Digital Analytics Program scripts for user behavior insights. The site is well-optimized for mobile devices, accessible, and demonstrates excellent SEO practices. Security is robust with HTTPS enforced, Content Security Policy headers, and anonymized IP tracking in analytics, although additional security headers could enhance protection. From a security perspective, the site shows maturity with no evident vulnerabilities or exposed sensitive data. It includes privacy and vulnerability disclosure policies, reflecting a commitment to compliance and transparency. The absence of WHOIS data is typical for .gov domains and does not detract from the site's legitimacy. Overall, the site is trustworthy, professional, and secure, serving a critical government function. The overall risk is low, with recommendations focusing on enhancing security headers, implementing DNSSEC, and publishing a security.txt file to further improve security posture and transparency.

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 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

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

The TSP website represents a critical government service providing retirement savings solutions to a large, defined customer base of federal employees and uniformed service members. Its business model is non-commercial, focused on public service and compliance with federal regulations. The site demonstrates strong market positioning as the official source for TSP information, supported by comprehensive content and user resources. The presence of a vulnerability disclosure policy indicates a proactive security stance. The partnership with the Federal Retirement Thrift Investment Board (frtib.gov) is evident, reinforcing its authoritative status. Growth indicators include regular updates and new fund offerings. The site’s ecosystem includes integration with government analytics and search services, enhancing user engagement and operational insights.

Security posture

The website exhibits a mature security posture with HTTPS enforced site-wide, Content Security Policy headers, and anonymized IP tracking in analytics scripts. The presence of a vulnerability disclosure policy and contact channels for security issues indicates readiness for incident response. No critical vulnerabilities or exposed sensitive data were detected. However, the site could improve by adding additional security headers such as X-Frame-Options and Referrer-Policy, implementing DNSSEC, and publishing a security.txt file to facilitate vulnerability reporting. Compliance with privacy regulations is evident but GDPR applicability is limited due to the U.S. government context. Overall, the security culture appears strong with good practices in place.

Recommendations

  1. Implement additional security headers including X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to enhance protection against common web attacks.
  2. Enable DNSSEC for the domain to improve DNS security and prevent spoofing.
  3. Publish a security.txt file at the root domain to provide clear vulnerability disclosure and security contact information.
  4. Regularly review and update privacy and cookie policies to maintain compliance with evolving regulations.
  5. Enhance transparency by providing more detailed business and security certifications on the website.

Technical notes

Notes

The website is built on a modern, static site architecture using Jekyll, which supports fast loading times and ease of maintenance. It leverages the U.S. Web Design System (USWDS) for consistent government branding and accessibility compliance. Integration with Google Analytics and the Digital Analytics Program provides robust data collection for user behavior analysis. The site is mobile-optimized and includes accessibility features such as skip navigation links and ARIA roles. Performance is fast with minimal external dependencies. Technical risks are low, though the absence of DNSSEC and some security headers represent minor areas for improvement. Overall, the technical infrastructure is solid and well-suited for a government service website.
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.
