Data Access Tiers and Entitlements

Censys offers tiered data access solutions for a wide range of users, from hobbyists to enterprise security teams. All customers begin with a Free account which offers basic internet visibility, access to basic protocols & certificates, and limited web property data such as root endpoints.

This provides Censys users with a starting point to explore the internet landscape. To access more advanced data that provides deeper insights, you must upgrade to a higher-tiered account. Each tier builds upon comprehensive internet scanning data, offering progressively deeper insights into hosts, services, certificates, and potential security risks.

Censys offers Free, Starter, Core, and Enterprise tiers, as well as additional modules to address specific use cases. Each tier unlocks additional capabilities while maintaining strict data quality and accuracy that security professionals rely on for critical decisions.

If you encounter data with a lock icon, you must upgrade to access that data. If you see a 🔒 lock icon next to a dataset, it means that you must upgrade to view the data. Upgrading your account unlocks this data and provides enhanced security insights.

Censys tiers

The sections below provide a brief overview of the data visibility for Censys tiers.

Free

The Free tier is designed for preliminary security investigations. Users can search and view basic protocols and services, but some protocols and their attendant data are excluded. If you want to search for a protocol like MSMQ and view its data, you must upgrade to a paid account.

Basic certificate information is searchable and viewable for free users. To search for advanced certificate fields and view historical data, you must upgrade to a paid tier. Free tiers are limited to 1 page of results.

The Free tier allows users to search and view basic web properties like root endpoints. To access the following assets, you must upgrade:

• Endpoint resources, non-root endpoints (Starter and Enterprise)
• Threat actor endpoints (Enterprise)
• Deep application scanners (Enterprise)
• Advanced queries using regex (Starter and Enterprise)
• Additional protocols and applications, including cobalt strike (Enterprise)

📘

Note

The Free tier does not provide access to the Censys API.

Starter

If you purchase credits through the Censys website, your account is upgraded to the Starter tier, granting comprehensive internet visibility and actionable insights. On the Starter tier, you can:

• Search and view basic and advanced protocols and services that unlock deeper data.
• View one week of host history.
• Create up to two collections.

Starter tier accounts are limited to a maximum of 500 results per search query.

The Starter tier allows users to search and view all certificate data, including certificates expired for more than 30 days. Web property data such as complete endpoints are searchable and viewable, providing insights into devices, services, and systems exposed on the internet.

To access the following assets, you must upgrade:

• Threat actor endpoints (Enterprise)
• Deep application scanners (Enterprise)
• Additional protocols and applications, including cobalt strike (Enterprise)

📘

Note

The Starter tier provides access to the Censys API.

Core and Enterprise

Enterprise-level access includes two tiers: Core and Enterprise. Vulnerability data is not available to the Core tier, but is available to the Enterprise tier. The Enterprise tier is priced higher than Core because of access to this additional data.

Both tiers offer full protocol data access and advanced internet visibility provided by deep application scanners. This allows you to search and view protocols, services, web applications, and view 1 month of host history, excluding industrial control system (ICS) protocols. Enterprise search results include all CPE-based fields and provide access to unlimited paginated results. Raw and JSON data can be viewed and downloaded.

Threat-specific data is available in the Threat Hunting module, which may be purchased by Enterprise customers.

Enterprise customers may purchase access to ICS protocol data separately.

Note

The Enterprise tier provides access to the Censys API.
