Security checks

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

Security Headers
3/5 security headers present. Missing: Referrer-Policy, Permissions-Policy.
Needs work
Certificate Hygiene
Strengths: Certificate valid, 86 days remaining; Issued by Let's Encrypt. Issues: Wildcard certificate in use — broader attack surface if compromised.
Needs work
DNS Configuration
Strengths: 2 nameservers configured (daisy.ns.cloudflare.com., isaac.ns.cloudflare.com.); 5 MX records present; DNSSEC enabled; Zone transfers properly restricted.
Healthy
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
DMARC / Email Security
Strengths: DMARC policy set to reject (strongest); SPF record present with soft-fail (~all); DKIM configured (selectors: s1).
Healthy
HSTS Header
HSTS enabled: max-age=31536000. includeSubDomains present. Missing preload directive.
Healthy
CVE Exposure
No server software versions detected in HTTP response headers. This is good practice (version hiding) but means CVE exposure cannot be assessed from external signals alone.
Healthy

Steps to improve casetext.com's security grade, ranked by impact.

1
Add optional security headers (Referrer-Policy, Permissions-Policy)
Impact: < 1 Hour
LOW
casetext.com has most security headers configured. Missing: Referrer-Policy, Permissions-Policy. These are best-practice additions that reduce the attack surface for client-side vulnerabilities.
How to fix this
1
Add: Referrer-Policy: strict-origin-when-cross-origin
2
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
3
Verify with: curl -sI https://casetext.com | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
2
Review certificate configuration
Impact: 1–2 Hours
LOW
Certificate issues found for casetext.com: wildcard certificate in use. Wildcard certificates have a broader blast radius if compromised. These are operational hygiene items, not immediate security risks.
How to fix this
1
Consider replacing wildcard cert with individual certs for critical subdomains
2
Consolidate certificate issuance to 1–2 trusted CAs
