Know your entire
attack surface
Discover every domain, subdomain, and exposed service. Validate TLS certificates, fingerprint tech stacks, and find vulnerabilities before attackers do.
Attack surface discovery
Enter your root domain and Scuto maps everything — subdomains, DNS records, exposed services, and IP addresses. Continuously monitored so new assets never slip through.
- Subdomain enumeration via DNS, certificate transparency, and brute force
- Dangling CNAME detection to prevent subdomain takeover
- Continuous monitoring — get alerted when new subdomains appear
TLS certificate validation
Validate every certificate across your domains — check expiry dates, cipher strength, protocol versions, and certificate chain integrity. Get alerted before certificates expire.
- Grade every certificate from A+ to F based on configuration strength
- Expiry alerts at 30, 14, and 7 days — never get caught off guard
- Flag weak ciphers, deprecated TLS versions, and self-signed certificates
Tech stack fingerprinting
Automatically detect what's running on each domain — web servers, frameworks, CDNs, and WAFs. Know exactly what's exposed and where your gaps are.
- Detect web servers, frameworks, CMS platforms, and JavaScript libraries
- Identify CDN and WAF presence — flag unprotected endpoints
- Match detected versions against CVE databases for known vulnerabilities
Deep subdomain enumeration
Combine multiple discovery techniques — DNS enumeration, certificate transparency logs, and smart brute force — to find every subdomain, including ones you forgot about.
- Multi-source discovery combining passive and active techniques
- Port scanning on discovered subdomains to map exposed services
- Diff between scans — see what's new, changed, or disappeared
More capabilities
Everything you need to map, monitor, and secure your external attack surface.
Scheduled Scanning
Continuous monitoring on a schedule. Get alerted when new subdomains appear or certificates are about to expire.
Dangling DNS Detection
Find CNAME records pointing to deprovisioned services — preventing subdomain takeover attacks before they happen.
Port Scanning
Discover exposed ports and services across your entire attack surface. Flag unexpected listeners and shadow IT.
Header Analysis
Check for missing security headers — HSTS, CSP, X-Frame-Options, and more. Get remediation guidance for each.
WHOIS & DNS Intelligence
Track domain registration, nameserver changes, and DNS record modifications. Get alerted on unauthorized changes.
Compliance Mapping
Map TLS configuration and exposed services to SOC 2, ISO 27001, and PCI DSS controls automatically.
