Action Items
Ordered by priority · 5 items
1
Strengthen email authentication configuration
Email authentication is partially configured for sendgrid.com 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
Remediation Steps
1
Add SPF record if missing: v=spf1 include:_spf.google.com -all
2
Verify with: nslookup -type=txt _dmarc.sendgrid.com

2
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for sendgrid.com can be spoofed, potentially redirecting users to malicious sites. This requires coordination with your domain registrar to publish DS records.
Compliance Impact
NIST 800-53SC-20
Secure name/address resolution service
Remediation Steps
1
Check if your DNS provider supports DNSSEC (Cloudflare, Route53, etc.)
2
Enable DNSSEC signing in your DNS provider dashboard
3
Add the DS record to your registrar for .com TLD
4
Verify: dig +dnssec sendgrid.com
3
Review certificate configuration — expires in 21 days
Certificate issues found for sendgrid.com: certificate expires in 21 days; wildcard certificate in use. Wildcard certificates have a broader blast radius if compromised. Ensure auto-renewal is configured to prevent expiry. These are operational hygiene items, not immediate security risks.
Remediation Steps
1
Verify auto-renewal is configured (Let's Encrypt: certbot renew --dry-run)
2
Consider replacing wildcard cert with individual certs for critical subdomains
3
Consolidate certificate issuance to 1–2 trusted CAs
4
Increase HSTS max-age duration
HSTS is enabled but the max-age (0s) is below the recommended minimum of 15768000s (6 months). A short max-age means browsers forget the HTTPS-only policy quickly, reducing protection between visits.
Compliance Impact
PCI-DSS 4.0Req 6.4.1
Application security header configuration
Remediation Steps
1
Update header: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
2
Verify: curl -sI https://sendgrid.com | grep -i strict
5
Upgrade to TLS 1.3
sendgrid.com negotiated TLSv1.2. TLS 1.2 is still compliant under all major security frameworks and is not a vulnerability. TLS 1.3 offers faster handshakes and removes legacy cipher negotiation. This is a best-practice improvement, not a compliance gap.
Remediation Steps
1
Update web server config to prefer TLS 1.3 (nginx: ssl_protocols TLSv1.2 TLSv1.3)
2
Verify: openssl s_client -connect sendgrid.com:443 -tls1_3
