Security teams hunting for leaked credentials, API keys, or proprietary code snippets in the wild should start with PublicWWW; it's the fastest way to search billions of indexed web pages for specific alphanumeric patterns you actually care about rather than drowning in generic vulnerability feeds. The free tier lets you run unlimited searches without authentication, so you can validate the signal before committing budget. Skip this if you need automated monitoring of your own source code repositories or continuous scanning of your attack surface; PublicWWW is a manual reconnaissance tool, not a backstop for insider threats or CI/CD pipeline leaks.
Matos Automated Attack Surface Management
Startups and SMBs with sprawling multi-cloud footprints should pick Matos Automated Attack Surface Management because it finds shadow assets and orphaned infrastructure that your teams don't know exist, without requiring agents or manual tuning. The continuous discovery engine covers ID.AM (asset inventory) and DE.CM (anomaly detection) simultaneously, meaning you get both visibility and active monitoring from one deployment. Skip this if you need deep vulnerability correlation across on-premises datacenters; Matos is cloud-native by design and will feel limited in hybrid environments with heavy legacy infrastructure.
