Security checks

Each check inspects a different part of calii.com'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.
Problem
DMARC / Email Security
Strengths: DKIM configured (selectors: s1, s2). Issues: DMARC policy is 'none' (monitoring only, no enforcement); No SPF record found.
Problem
DNS Configuration
Strengths: 4 nameservers configured (ns1.dnsimple.com., ns2.dnsimple-edge.net., ns3.dnsimple.com., ns4.dnsimple-edge.org.); 5 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
Needs work
Security Headers
3/5 security headers present. Missing: CSP, Permissions-Policy.
Needs work
Known Breaches
No known breaches found in public disclosure databases.
Healthy
TLS Configuration
TLSv1.3 negotiated with TLS_AES_128_GCM_SHA256 (128-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
Healthy
CVE Exposure
Detected technologies: Heroku, Proxy/CDN. (Proxy/CDN detected but excluded from CVE matching — upstream infrastructure). No version information exposed — CVE matching not possible (this is good practice).
Healthy
Certificate Hygiene
Strengths: Certificate valid, 69 days remaining; Issued by Let's Encrypt.
Healthy

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

1
Set up email authentication (SPF)
Impact: 1–2 Days
CRITICAL
Without email authentication, anyone can send emails that appear to come from calii.com. This is the most common vector for phishing attacks targeting employees and customers. SPF is not configured.
Compliance impact
NIST CSFPR.AC-7
Email authentication is a required access control
ISO 27001A.13.2.1
Information transfer policies require email security controls
HIPAA§164.312(e)
Transmission security for electronic PHI
How to fix this
1
Add SPF record to DNS: v=spf1 include:_spf.google.com ~all (adjust for your email provider)
2
Configure DKIM signing with your email provider and publish the public key in DNS
3
Add DMARC record: v=DMARC1; p=quarantine; rua=mailto:[email protected]
4
Monitor DMARC reports for 2–4 weeks, then upgrade policy to p=reject
2
Enable HSTS (HTTP Strict Transport Security)
Impact: < 1 Hour
HIGH
The HSTS header is missing on calii.com. 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://calii.com | grep -i strict
4
Submit to hstspreload.org after confirming the header is correct
3
Enable DNSSEC on your domain
Impact: 1–3 Days (Depends On Registrar)
MEDIUM
Without DNSSEC, DNS responses for calii.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 calii.com
4
Add optional security headers (CSP, Permissions-Policy)
Impact: < 1 Hour
LOW
calii.com has most security headers configured. Missing: CSP, Permissions-Policy. These are best-practice additions that reduce the attack surface for client-side vulnerabilities.
How to fix this
1
Add Content-Security-Policy header (start with report-only to avoid breakage)
2
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
3
Verify with: curl -sI https://calii.com | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
