upcall.com — Grade B (85/100)
2378 companies scanned
Security checks
Each check inspects a different part of upcall.com's public security setup. Green means healthy, yellow needs attention, red is a problem.
DNS Configuration
Strengths: 3 nameservers configured (ns-24-c.gandi.net., ns-198-b.gandi.net., ns-225-a.gandi.net.); 5 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
DMARC / Email Security
Strengths: SPF record present with soft-fail (~all); DKIM configured (selectors: google, s1, s2, smtpapi). Issues: DMARC policy is 'none' (monitoring only, no enforcement); DMARC has no aggregate report URI (rua).
Security Headers
3/5 security headers present. Missing: CSP, Permissions-Policy.
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. includeSubDomains present. Missing preload directive.
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, 365 days remaining; Issued by Gandi SAS.
Recommended actions
3 items
Steps to improve upcall.com's security grade, ranked by impact.
1
Strengthen email authentication configuration
Email authentication is partially configured for upcall.com 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.upcall.com

2
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for upcall.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 upcall.com
3
Add optional security headers (CSP, Permissions-Policy)
upcall.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://upcall.com | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
