About RedGem

See what attackers see

RedGem gives you complete external visibility — into your digital assets and your attack surface. Spot public-facing vulnerabilities and leaked credentials before attackers do, and stay ahead of new CVEs, exploits, and security news.

Complete external visibility

See your organization exactly as an attacker would.

Critical risk identification

Surface public-facing vulnerabilities and leaked credentials first.

Proactive threat intelligence

Real-time alerts on new CVEs, exploits, and security news.

Digital footprint monitoring

Automatic discovery and tracking of every public-facing asset.

One platform, your whole attack surface

Discover, scan, and defend — automatically

Four connected modules give you everything an attacker can see about your organization — and a head start on fixing it.

Asset Discovery & Monitoring

Map and watch your entire attack surface

You can't secure what you don't know about. RedGem keeps a live inventory of every subdomain, IP, port, and service — and tells you the moment something changes.

  • Automatic subdomain, IP & port inventory
  • SSL, web-service & technology change detection
  • Real-time alerts on every new or changed asset

How RedGem works

Four steps from a single domain to a continuously defended attack surface

1

Connect a domain

Add a domain and RedGem starts mapping everything attached to it.

2

Discover assets

Subdomains, IPs, ports, and services are inventoried automatically.

3

Scan & enrich

Continuous scans surface vulnerabilities, leaks, and CVEs that affect you.

4

Get alerted

Severity-ranked alerts reach your team the moment something changes.
