Security checks
Each check inspects a different part of colabsoftware.com'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.
Certificate Hygiene
Strengths: Certificate valid, 53 days remaining; Issued by Google Trust Services. Issues: Wildcard certificate in use — broader attack surface if compromised.
DNS Configuration
Strengths: 5 nameservers configured (franklin.ns.colabsoftware.com., hopper.ns.colabsoftware.com., tesla.ns.colabsoftware.com., curie.ns.colabsoftware.com.); 5 MX records present; DNSSEC enabled; Zone transfers properly restricted.
Known Breaches
No known breaches found in public disclosure databases.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
HSTS Header
HSTS enabled: max-age=31536000. Missing includeSubDomains. Missing preload directive.
DMARC / Email Security
Strengths: DMARC policy set to quarantine; SPF record present with soft-fail (~all); DKIM configured (selectors: google).
CVE Exposure
Detected technologies: cloudflare. (cloudflare detected but excluded from CVE matching — upstream infrastructure). All detected technologies are upstream CDN/proxy infrastructure. No application-level software versions exposed.

Steps to improve colabsoftware.com's security grade, ranked by impact.
1
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 colabsoftware.com: 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

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://colabsoftware.com | grep -iE 'content-security|x-frame|x-content|referrer|permissions'

Review certificate configuration
Certificate issues found for colabsoftware.com: wildcard certificate in use. Wildcard certificates have a broader blast radius if compromised. Ensure auto-renewal is configured to prevent expiry. These are operational hygiene items, not immediate security risks.
How to fix this
1
Verify auto-renewal is configured (Let's Encrypt: certbot renew --dry-run)
2
Consider replacing wildcard cert with individual certs for critical subdomains
3
Consolidate certificate issuance to 1–2 trusted CAs
