Security checks

Each check inspects a different part of gsa.gov's public security setup. Green means healthy, yellow needs attention, red is a problem.

DMARC / Email Security
Strengths: DMARC policy set to reject (strongest); DKIM configured (selectors: google, s1, s2). Issues: No SPF record found.
Needs work
Known Breaches
No known breaches found in public disclosure databases.
Healthy
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
Healthy
HSTS Header
HSTS enabled: max-age=31536000 with includeSubDomains and preload. Meets best-practice configuration.
Healthy
Security Headers
4/5 security headers present. Missing: CSP.
Healthy
CVE Exposure
Detected technologies: Proxy/CDN. (Proxy/CDN detected but excluded from CVE matching — upstream infrastructure). All detected technologies are upstream CDN/proxy infrastructure. No application-level software versions exposed.
Healthy
DNS Configuration
Strengths: 5 nameservers configured (dns2.gsa.gov., dns.gsa.gov., dns3.gsa.gov., dns5.gsa.gov.); 5 MX records present; DNSSEC enabled; Zone transfers properly restricted.
Healthy
Certificate Hygiene
Strengths: Certificate valid, 63 days remaining; Issued by Let's Encrypt.

Recommended actions
1 item

Steps to improve gsa.gov's security grade, ranked by impact.

1
Strengthen email authentication configuration
Impact: 2–4 Hours
HIGH
Email authentication is partially configured for gsa.gov but has gaps. Actions needed: add SPF record. Until DMARC enforcement is active, spoofed emails may still reach recipients.
Compliance impact
NIST CSFPR.AC-7
Email authentication is a required access control
How to fix this
1
Add SPF record if missing: v=spf1 include:_spf.google.com -all
2
Verify with: nslookup -type=txt _dmarc.gsa.gov
