manicule.dev — Grade B- (80/100) 2394 companies scanned
Security checks

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

Security Headers
None of the 5 recommended security headers are 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.
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
No CAA records found. Without CAA, any Certificate Authority can issue certificates for this domain. Adding CAA records restricts issuance to authorized CAs only, reducing the risk of misissued certificates.
Needs work
DNS Configuration
Strengths: 2 nameservers configured (tom.ns.cloudflare.com., walk.ns.cloudflare.com.); 5 MX records present; Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
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
DMARC / Email Security
Strengths: SPF record present with soft-fail (~all); DKIM configured (selectors: google). Issues: DMARC policy is 'none' (monitoring only, no enforcement); DMARC has no aggregate report URI (rua).
Needs work
MX Records & Mail Provider
Strengths: Mail handled by Google Workspace; 5 MX record(s) configured; Multiple MX records provide redundancy.
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
TLS Configuration
TLSv1.3 negotiated with TLS_AES_128_GCM_SHA256 (128-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
Healthy
HSTS Header
HSTS enabled: max-age=63072000s (730 days). Missing includeSubDomains — subdomains not covered. Missing preload directive.
Healthy
Known Breaches
No known breaches found in public disclosure databases.
Healthy
Cookie Security
No cookies set on the homepage response. No cookie security flags to evaluate.
Healthy
CVE Exposure
Detected technologies: Vercel. (Vercel detected but excluded from CVE matching — upstream infrastructure). All detected technologies are upstream CDN/proxy infrastructure. No application-level software versions exposed.
Healthy
Certificate Hygiene
Strengths: Certificate valid, 41 days remaining; Issued by Let's Encrypt; 24 certificates logged in CT; Certificates from 2 CAs: Let's Encrypt, Sectigo Limited. Note: Wildcard certificate in use (*.domain) — covers all subdomains. Common practice; worth noting that compromise would affect all subdomains.
Healthy

Steps to improve manicule.dev's security grade, ranked by impact.

1
Add missing security headers (CSP, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy)
Impact: 1–2 Hours
HIGH
5 of 5 recommended security headers are missing on manicule.dev: 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 a Content-Security-Policy header. Safe starting value (works with Google Fonts and inline styles/scripts): default-src 'self'; style-src 'self' 'unsafe-inline' https://fonts.googleapis.com; font-src 'self' https://fonts.gstatic.com; script-src 'self' 'unsafe-inline'; upgrade-insecure-requests. Test your site after adding it, then tighten over time by removing 'unsafe-inline'.
2
Add: X-Content-Type-Options: nosniff
3
Add: X-Frame-Options: SAMEORIGIN (use DENY only if you never embed your pages in iframes)
4
Add: Referrer-Policy: strict-origin-when-cross-origin
5
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
6
Verify with: curl -sI https://manicule.dev | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
2
Strengthen email authentication configuration
Impact: 2–4 Hours
HIGH
Email authentication is partially configured for manicule.dev 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.manicule.dev
3
Enable DNSSEC on your domain
Impact: 1–3 Days (Depends On Registrar)
MEDIUM
Without DNSSEC, DNS responses for manicule.dev 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 .dev TLD
4
Verify: dig +dnssec manicule.dev
