Censys Playbook: Outside-In Exposure Checks on Your Own Estate with CenQL, cencli, the Platform API and ASM
A hands-on Censys guide checked against Censys's own documentation: authenticate cencli and the Platform API, write CenQL queries for your own ranges, certificates and end-of-life software, paginate and budget credits, diff outside-in results against your inventory, and run attack surface management without noise.
- Authenticate cencli with OAuth or a token, and set the organisation every time
- CenQL queries for your own CIDRs, management ports, expiring certificates and EOL software
- Paginate the search API, and budget credits before a script burns them
- Diff outside-in results against your inventory to find unowned exposure
- Spot Censys's own scanners in your logs, and why blocking them fixes nothing
- Run ASM seeds, exclusions and risk tuning so alerts mean something
- A 90-day rollout and an acquisition-style interview drill
