What this means
flinto.app scored 65/100, meeting baseline requirements but with 0 findings that require attention. The vendor can proceed with a remediation timeline agreement.
Critical gaps in: HSTS Header, Security Headers, DMARC / Email Security. Positive signals: Known Breaches, TLS Configuration, CVE Exposure 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 flinto.app'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
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.
DMARC / Email Security
Issues: No DMARC record found — email spoofing is not prevented; No SPF record found; No DKIM records found for common selectors (domain may use custom selectors — this is not a confirmed gap).
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.
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.
DNS Configuration
Strengths: 4 nameservers configured (ns-cloud-e1.googledomains.com., ns-cloud-e2.googledomains.com., ns-cloud-e4.googledomains.com., ns-cloud-e3.googledomains.com.); DNSSEC enabled; Zone transfers properly restricted.
Certificate Hygiene
Strengths: Certificate valid, 34 days remaining; Issued by Let's Encrypt.

Steps to improve flinto.app's security grade, ranked by impact.
1
Set up email authentication (DMARC, SPF, DKIM)
Without email authentication, anyone can send emails that appear to come from flinto.app. This is the most common vector for phishing attacks targeting employees and customers. DMARC, SPF, 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 HSTS (HTTP Strict Transport Security)
The HSTS header is missing on flinto.app. 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://flinto.app | grep -i strict
4
Submit to hstspreload.org after confirming the header is correct
3
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 flinto.app: 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 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://flinto.app | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
