Capabilities

Everything in your attack surface,
nothing left in the dark.

Sharingan chains passive enumeration, active probing, and continuous monitoring into a single platform — so you always know what's exposed.

Passive Discovery

Harvest subdomains from certificate transparency logs, subfinder, crt.sh, and more — without touching the target network.

DNS Resolution & Brute-force

Resolve every discovered hostname with dnsx and run wordlist-driven brute-force with multi-million entry lists stored in optimised volumes.

HTTP Fingerprinting

Run httpx across live subdomains to capture status codes, titles, tech stacks, and etc. — continuously updated.

Signal Intelligence

Every DNS change, new subdomain, and HTTP state transition emits a severity-graded signal. Triage from a unified feed or get Telegram alerts.

Real-time CT Streaming

Subscribe to live certificate issuance feeds. New subdomains matching your scope are ingested seconds after the certificate is signed.

HackerOne Import

Drop in a HackerOne program scope CSV and Sharingan automatically parses wildcard and explicit scope entries into your asset inventory.

Workflow

From zero to full visibility in three steps.

Define your scope

Add companies and seed domains manually, via bulk upload, or by importing directly from a HackerOne program scope CSV. Sharingan instantly scaffolds your asset tree.

Enumerate & probe

Workers fire across dedicated VPS nodes — passive engines find subdomains, dnsx resolves them, httpx fingerprints every live service, and CT streams watch for new certs in real time.

Monitor & act on signals

Every state change — new subdomain, DNS mutation, HTTP status flip — produces a severity-graded signal. Review in the dashboard or receive instant Telegram notifications.

Here's what a real recon run looks like — from passive discovery to a graded signal, in seconds.
