External Attack Surface Management

Know every asset an attacker can see.

Give us a domain. We map your entire internet-facing footprint — subdomains, live web apps, IP addresses, TLS certificates and exposed cloud assets — then keep watching it for change.

What we do

Most breaches start with an asset nobody remembered owning — a forgotten subdomain, an expired cert, a public bucket. We find those before someone else does, from the outside in, using only the domain you give us.

Discover

Enumerate the full subdomain and asset footprint from 40+ passive sources, certificate transparency and active resolution.

Validate

Resolve DNS, confirm which hosts are actually live, fingerprint their tech and capture certificates — only real, reachable assets.

Monitor

Re-scan on a schedule and get told what's new, what changed and what disappeared — before it becomes an incident.

Report

A clean inventory per asset type in your portal, with vulnerability insights layered on top (coming soon).

Everything we inventory

One domain in — a complete, categorized asset inventory out. Each category is its own tab in your dashboard.

Subdomains

Every name under your domain, resolved and de-duplicated — we surface only the live ones.

Web Applications

Live HTTP services with status, title, server and detected technologies — your real app inventory.

IP Addresses

The addresses your assets resolve to, with hosting and network context.

TLS Certificates

Issuers, validity windows and SANs — catch expiring, self-signed or rogue certificates early.

Cloud Assets

Buckets and storage endpoints referenced by your apps — flagged when publicly exposed.

Soon

Vulnerabilities

Prioritized findings per asset — CVEs, misconfigurations and takeovers, ranked by real-world risk.

How it works

Three steps from a single domain to a full picture of your exposure.

01

Submit your domain

Confirm you're authorized to assess it. Passive discovery never touches your target; active probing waits for the next step.

02

We map the surface

Once approved, ephemeral workers spin up, run the discovery pipeline and tear themselves down. Time-boxed, rate-limited and cost-capped.

03

Explore your inventory

Browse assets by category in your dashboard, watch progress live, and request deeper checks where you need them.

Built responsibly

Authorized, controlled, accountable

Active scanning sends real traffic to real targets. We treat that seriously: nothing runs without authorization and operator approval, and every action is attributed and logged.
