Critical gaps in: DMARC / Email Security. Positive signals: MX Records & Mail Provider, TLS Configuration, TLS Protocol Support all passed.

3 action items identified, including 1 critical. The issues are configuration gaps, not architectural problems. A focused remediation effort of 2–5 days could address all findings.

Security checks

Each check inspects a different part of app.cymulate.com's public security setup. Green means healthy, yellow needs attention, red is a problem.

DMARC / Email Security
Strengths: SPF record present with hard-fail (-all). Issues: No DMARC record found — email spoofing is not prevented; No DKIM records found for common selectors (domain may use custom selectors — this is not a confirmed gap).
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.
Needs work
DNS CAA Records
Strengths: CAA records configured (12 record(s)); Authorized CAs: amazon.com, amazonaws.com, amazontrust.com, awstrust.com, letsencrypt.org. Issues: No iodef record — CA violations won't be reported to the domain owner.
Needs work
DNS Configuration
Strengths: DNSSEC enabled. Issues: No NS records found (unusual).
Needs work
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.
Needs work
Certificate Hygiene
Strengths: Certificate valid, 81 days remaining; Issued by Google Trust Services; 156 certificates logged in CT. Issues: Certificates issued by 7 different CAs (threshold: 5 for 156 logged certs) — possible misconfiguration or shadow IT. Note: Wildcard certificate in use (*.domain) — covers all subdomains. Common practice; worth noting that compromise would affect all subdomains.
Needs work
MX Records & Mail Provider
No MX records found. This domain does not receive email directly — this is intentional for many domains and carries no security risk. If email is expected, verify mail routing via A/AAAA fallback or a mail provider.
Healthy
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
Healthy
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.
Healthy
Known Breaches
No known breaches found in public disclosure databases.
Healthy
Cookie Security
Strengths: 1 cookie(s) analyzed; All cookies have Secure flag; All cookies have HttpOnly flag; All cookies have SameSite attribute.
Healthy
HSTS Header
HSTS enabled: max-age=31536000s (365 days). includeSubDomains present. Missing preload directive.
Healthy
Security Headers
4/5 security headers present. Missing: Permissions-Policy.
Healthy
CVE Exposure
Detected technologies: cloudflare, Proxy/CDN. (cloudflare, Proxy/CDN detected but excluded from CVE matching — upstream infrastructure). All detected technologies are upstream CDN/proxy infrastructure. No application-level software versions exposed.
Healthy

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

1
Set up email authentication (DMARC, DKIM)
Impact: 1–2 Days
CRITICAL
Without email authentication, anyone can send emails that appear to come from app.cymulate.com. This is the most common vector for phishing attacks targeting employees and customers. DMARC, DKIM are 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 DNSSEC on your domain
Impact: 1–3 Days (Depends On Registrar)
MEDIUM
Without DNSSEC, DNS responses for app.cymulate.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 app.cymulate.com
3
Review certificate configuration
Impact: 1–2 Hours
LOW
Certificate issues found for app.cymulate.com: wildcard certificate in use. Wildcard certificates have a broader blast radius if compromised. These are operational hygiene items, not immediate security risks.
How to fix this
1
Consider replacing wildcard cert with individual certs for critical subdomains
2
Consolidate certificate issuance to 1–2 trusted CAs
