Security checks
Each check inspects a different part of workflowy.com's public security setup. Green means healthy, yellow needs attention, red is a problem.
DNS Configuration
Strengths: 2 nameservers configured (candy.ns.cloudflare.com., weston.ns.cloudflare.com.); 5 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
Certificate Hygiene
Strengths: Certificate valid, 46 days remaining; Issued by Let's Encrypt. Issues: Wildcard certificate in use — broader attack surface if compromised.
Known Breaches
No known breaches found in public disclosure databases.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
HSTS Header
HSTS enabled: max-age=63072000 with includeSubDomains and preload. Meets best-practice configuration.
Security Headers
4/5 security headers present. Missing: Permissions-Policy.
DMARC / Email Security
Strengths: DMARC policy set to quarantine; SPF record present with soft-fail (~all); DKIM configured (selectors: google, s1, s2, k1, smtpapi). Issues: DMARC has no aggregate report URI (rua).
CVE Exposure
Detected technologies: nginx. No version information exposed — CVE matching not possible (this is good practice).

Steps to improve workflowy.com's security grade, ranked by impact.
1
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for workflowy.com can be spoofed, potentially redirecting users to malicious sites. This requires coordination with your domain registrar to publish DS records.
Compliance impact

Secure name/address resolution service
How to fix this
1
Check if your DNS provider supports DNSSEC (Cloudflare, Route53, etc.)
2
Enable DNSSEC signing in your DNS provider dashboard

2
Review certificate configuration
Certificate issues found for workflowy.com: 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.
How to fix this
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
