Security checks
Each check inspects a different part of daily.co's public security setup. Green means healthy, yellow needs attention, red is a problem.
Security Headers
Only 0/5 security headers present. Missing: CSP, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy. This exposes the application to clickjacking, MIME-sniffing, and other client-side attacks.
TLS Configuration
TLSv1.2 negotiated. Issues: TLS 1.2 negotiated (1.3 preferred).
DMARC / Email Security
Strengths: SPF record present with soft-fail (~all); DKIM configured (selectors: google, mandrill, cm, zendesk1, zendesk2). Issues: DMARC policy is 'none' (monitoring only, no enforcement).
DNS Configuration
Strengths: 4 nameservers configured (ns-170.awsdns-21.com., ns-746.awsdns-29.net., ns-1331.awsdns-38.org., ns-1660.awsdns-15.co.uk.); 5 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
Certificate Hygiene
Strengths: Certificate valid, 188 days remaining; Issued by Amazon. Issues: Wildcard certificate in use — broader attack surface if compromised.
Known Breaches
No known breaches found in public disclosure databases.
HSTS Header
HSTS enabled: max-age=63072000. Missing includeSubDomains. Missing preload directive.
CVE Exposure
Detected technologies: Vercel, Next.js. (Vercel detected but excluded from CVE matching — upstream infrastructure). No version information exposed — CVE matching not possible (this is good practice).
Recommended actions
5 items
Steps to improve daily.co's security grade, ranked by impact.
1
Strengthen email authentication configuration
Email authentication is partially configured for daily.co but has gaps. Actions needed: upgrade DMARC policy from 'none' to 'quarantine' or 'reject'. 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
Upgrade DMARC policy to p=quarantine (then p=reject after monitoring)
2
Verify with: nslookup -type=txt _dmarc.daily.co

2
Add missing security headers (CSP, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy)
5 of 5 recommended security headers are missing on daily.co: CSP, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy. These headers protect against clickjacking, MIME-sniffing, and unauthorized browser feature access. Adding them is a server configuration change with no application code changes required.
Compliance impact
PCI-DSS 4.0Req 6.4.1
Security headers are required application controls
OWASPSecure Headers
Recommended baseline for web applications
How to fix this
1
Add Content-Security-Policy header (start with report-only to avoid breakage)
2
Add: X-Content-Type-Options: nosniff
3
Add: X-Frame-Options: DENY (or SAMEORIGIN if you use iframes)
4
Add: Referrer-Policy: strict-origin-when-cross-origin
5
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
6
Verify with: curl -sI https://daily.co | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
3
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for daily.co 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
How to fix this
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 .co TLD
4
Verify: dig +dnssec daily.co
4
Upgrade to TLS 1.3
daily.co 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.
How to fix this
1
Update web server config to prefer TLS 1.3 (nginx: ssl_protocols TLSv1.2 TLSv1.3)
2
Verify: openssl s_client -connect daily.co:443 -tls1_3
5
Review certificate configuration
Certificate issues found for daily.co: 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
