Security checks
Each check inspects a different part of tiktok.com's public security setup. Green means healthy, yellow needs attention, red is a problem.
MTA-STS & TLS Reporting
Issues: No MTA-STS configured — email in transit is vulnerable to TLS downgrade attacks. Sending servers cannot verify that your mail server requires TLS; No TLSRPT record — TLS delivery failures won't be reported to domain owner.
DNS CAA Records
No CAA records found. Without CAA, any Certificate Authority can issue certificates for this domain. Adding CAA records restricts issuance to authorized CAs only, reducing the risk of misissued certificates.
DNS Configuration
Strengths: 6 nameservers configured (a18-64.akam.net., a12-66.akam.net., a6-65.akam.net., a1-97.akam.net.); 3 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
Cookie Security
Strengths: 1 cookie(s) analyzed; All cookies have Secure flag; All cookies have HttpOnly flag. Issues: 1/1 cookie(s) missing SameSite attribute (tt_chain_token).
security.txt (RFC 9116)
No security.txt found. Publishing a security.txt at /.well-known/security.txt is the industry standard (RFC 9116) for vulnerability disclosure policies. Its absence may indicate a less mature security program.
MX Records & Mail Provider
Strengths: Mail handled by mx1.tiktok.com; 3 MX record(s) configured; Multiple MX records provide redundancy.
TLS Protocol Support
Strengths: TLS 1.3 supported; TLS 1.2 supported; TLS 1.3 supported (strongest). Protocol support: TLS 1.3: Yes, TLS 1.2: Yes, TLS 1.1: No, TLS 1.0: No.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
Known Breaches
No known breaches found in public disclosure databases.
DMARC / Email Security
Strengths: DMARC policy set to reject (strongest); SPF record present with hard-fail (-all); DKIM configured (selectors: google, s1, s2, k1, cm). Issues: DMARC has no aggregate report URI (rua).
HSTS Header
HSTS enabled: max-age=31536000s (365 days). includeSubDomains present. Missing preload directive.
Security Headers
4/5 security headers present. Missing: Permissions-Policy.
CVE Exposure
Detected technologies: nginx, Goofy Node. No version information exposed — CVE matching not possible (this is good practice).
Certificate Hygiene
Strengths: Certificate valid, 57 days remaining; Issued by DigiCert Inc. Note: Wildcard certificate in use (*.domain) — covers all subdomains. Common practice; worth noting that compromise would affect all subdomains.
Recommended actions
1 item
Steps to improve tiktok.com's security grade, ranked by impact.
1
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for tiktok.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
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 .com TLD
4
Verify: dig +dnssec tiktok.com
