Security checks
Each check inspects a different part of palmeiras.com.br's public security setup. Green means healthy, yellow needs attention, red is a problem.
HSTS Header
Strict-Transport-Security header is missing. Connections can be downgraded to HTTP via man-in-the-middle attacks.
Security Headers
None of the 5 recommended security headers are 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.
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.
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 Microsoft 365; 2 MX record(s) configured; Multiple MX records provide redundancy.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
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.
DNS Configuration
Strengths: 3 nameservers configured (ns1.aziondns.net., ns3.aziondns.org., ns2.aziondns.com.); 2 MX records present; DNSSEC enabled; Zone transfers properly restricted.
Known Breaches
No known breaches found in public disclosure databases.
Cookie Security
No cookies set on the homepage response. No cookie security flags to evaluate.
DMARC / Email Security
Strengths: DMARC policy set to quarantine; SPF record present with hard-fail (-all); DKIM configured (selectors: selector1).
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.
Certificate Hygiene
Strengths: Certificate valid, 208 days remaining; Issued by GoDaddy.com, Inc..
Recommended actions

Steps to improve palmeiras.com.br's security grade, ranked by impact.
1
Enable HSTS (HTTP Strict Transport Security)
The HSTS header is missing on palmeiras.com.br. Without it, connections can be downgraded from HTTPS to HTTP via man-in-the-middle attacks. This is a straightforward server configuration change.
Compliance impact
PCI-DSS 4.0Req 6.4.1
Required application security controls
NIST 800-53SC-8
Transmission confidentiality and integrity
How to fix this
1
Add header: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
2
Verify all subdomains support HTTPS before adding includeSubDomains
3
Test with: curl -sI https://palmeiras.com.br | grep -i strict
4
Submit to hstspreload.org after confirming the header is correct

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 palmeiras.com.br: 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 a Content-Security-Policy header. Safe starting value (works with Google Fonts and inline styles/scripts): default-src 'self'; style-src 'self' 'unsafe-inline' https://fonts.googleapis.com; font-src 'self' https://fonts.gstatic.com; script-src 'self' 'unsafe-inline'; upgrade-insecure-requests. Test your site after adding it, then tighten over time by removing 'unsafe-inline'.
2
Add: X-Content-Type-Options: nosniff
3
Add: X-Frame-Options: SAMEORIGIN (use DENY only if you never embed your pages in iframes)
4
Add: Referrer-Policy: strict-origin-when-cross-origin
5
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
6
Verify with: curl -sI https://palmeiras.com.br | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
