Asset Inventory Exploration Page
What assets compose my inventory?
An attack surface can be composed of hosts, web entities, certificates, domains, and storage buckets.
-
Hosts are computers, virtual machines or devices connected to the Internet with an IP address.
-
Web entities are named entities running on a specific port that provide services or content using the HTTP protocol.
-
Domains (following the eTLD+1 format) are names that represent DNS zones.
-
Certificates are documents used during TLS handshakes to validate identities.
-
Storage buckets are object storage solutions available from Cloud Service Providers.
How do I use the Inventory list page?
The Inventory list page displays all of your organization’s assets.
You can explore, browse, and investigate these assets with basic and advanced searching.
Navigate to the page by opening the Inventory nav item and clicking the All Inventory option from the dropdown menu.

The default view of the table shows all asset types indexed by their ID, which is dependent on type. Columns in the default view apply to all assets of different types and include:
-
Risks - A count of any risks found on the asset by their severity.
-
Source - An enumeration indicating how the asset was added to your attack surface: as a seed, from a cloud connector, or via Censys discovery scans.
-
Tags - Any tags your team has applied to this asset.
-
Added - The date this asset was attributed to your organization.
Using the Search Bar
Provide search criteria using the Censys Search Language to search the fields listed in the ASM Asset schema docs.
Save queries by clicking the bookmark icon on the right side of the search bar and providing a name.

Open the Saved Queries menu to access and manage your team’s saved queries.

From this menu, you can run searches, edit the name, copy a query, or remove it from your list.
Column Selection
Additional columns are dependent on asset type and can be displayed in the table by clicking the plus (+) button at the far right of the header row.

Select or deselect the columns to create your desired view. Additional column options include:
