Multi-Layer Analysis

6 Inspection Layers

Every scan passes through six distinct inspection layers. Each layer analyzes a different dimension of your security posture.

L0

Transport Layer

TLS/SSL, cipher suites, certificate validation

L1

Protocol Layer

HTTP/2, HSTS, redirect chains, response headers

L2

Application Layer

CMS detection, CVE lookup, directory exposure

L3

Network Layer

Port scanning, subdomain discovery, WAF detection

L4

DNS Layer

DNSSEC, SPF, DKIM, DMARC, zone configuration

L5

Data Layer

Cookie attributes, mixed content, CSP enforcement

Scanner Modules

150+ Professional Scanners

Each scanner module is purpose-built for a specific security domain. Modules are organized into 6 categories with individual findings, severity scores, and remediation guidance.

SSL & Encryption

Validates certificate chains, cipher suites, and protocol versions to ensure encrypted connections meet modern standards.

  • SSL Certificate Validator

    Checks validity, expiry, issuer trust chain, and key strength

  • TLS Protocol Checker

    Detects deprecated TLS 1.0/1.1 and weak cipher suites

  • Certificate Chain Analysis

    Verifies complete chain of trust from root to leaf

  • HSTS Enforcement

    Checks HTTP Strict Transport Security headers and preload status

HTTP Security Headers

Audits response headers that control browser security behavior — from CSP to X-Frame-Options.

  • Security Headers Audit

    Full header analysis: CSP, X-Content-Type, Referrer-Policy

  • CORS Configuration

    Detects overly permissive cross-origin resource sharing

  • Cookie Security Check

    Validates Secure, HttpOnly, SameSite, and Path attributes

  • Mixed Content Detection

    Identifies HTTP resources loaded on HTTPS pages

Pro+

Network & Infrastructure

Probes network-level exposure including open ports, subdomain enumeration, and WAF detection.

  • Port Scanner

    Non-intrusive scan of common service ports (top 1000)

  • Subdomain Enumeration

    Discovers subdomains via DNS, certificate transparency logs

  • DNS Security Check

    Validates DNSSEC, zone transfers, dangling CNAMEs

  • WAF Detection

    Identifies web application firewall vendor and configuration

Pro+

Application Security

Fingerprints technology stacks, checks for known CVEs, and discovers exposed directories and endpoints.

  • Technology Detection

    Identifies CMS, frameworks, libraries, and server software

  • CMS Version Check

    Detects outdated WordPress, Drupal, Joomla versions

  • CVE Database Lookup

    Cross-references detected software against NVD/MITRE CVE data

  • Directory Listing Scan

    Checks for exposed directories, backup files, .git/.env

Email & DNS Authentication

Validates email authentication records to prevent spoofing, phishing, and deliverability issues.

  • SPF Record Analysis

    Checks Sender Policy Framework record syntax and coverage

  • DKIM Validation

    Validates DomainKeys Identified Mail signatures and key strength

  • DMARC Policy Check

    Verifies DMARC alignment, policy enforcement, and reporting

  • MX & Mail Security

    Checks MX records, STARTTLS support, and DANE/TLSA

Performance & Configuration

Analyzes configuration files, redirect chains, and performance metrics that affect security posture.

  • Performance Metrics

    TTFB, resource loading, render-blocking asset analysis

  • Robots.txt Audit

    Checks for sensitive paths exposed via robots.txt

  • Redirect Chain Analysis

    Maps redirect hops and detects open redirect vulnerabilities

  • API Endpoint Discovery

    Discovers exposed API endpoints from sitemap, JS bundles

Verified Owner Access

Deep scans require domain verification

Advanced scanners (network probing, directory listing, CVE exploitation checks) can reveal sensitive configuration details. To protect website owners, these modules are gated behind domain ownership verification.

1

Add DNS TXT record

Place a unique verification token in your domain's DNS records.

2

Or add a meta tag

Add a <meta> tag with your verification token to your homepage.

3

Verification completes

We validate ownership and unlock the full scanner suite for your domain.
