Transition Guides for Free Users, Solo, and Teams Subscribers

Censys offers tiered data access solutions for a wide range of users, from hobbyists to enterprise security teams. The Free tier is designed for preliminary security investigations. Users can search and view basic protocols and services, but ICS protocols are excluded. For example, you can search for host.services.ftp.banner to view specific details about a banner message provided by the service. If you want to search for advanced protocols 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)
• Threat actor endpoints (Enterprise)
• Deep application scanners (Enterprise)
• Cobalt strike, for red teams to test an org's vulnerabilities (Enterprise)

We introduced a new data model in the Censys Platform that includes three datasets: hosts, certificates, and web properties. Search functionality in the Censys Platform was enhanced, both syntax and semantics have changed since Legacy Search. Due to schema changes, you must define the dataset by prepending your search with host., cert., or web..

📘

Due to schema and syntax changes, you must modify your queries for them to return the same results.

The Censys Platform now uses a new query language that provides the following benefits:

• Universal search allows users to easily search across multiple datasets with one query.
• Search now includes a query validator that verifies syntax and assists with troubleshooting.
• Simplified regex searches and improved the use of operators.
• Wildcard no longer supported, use regex instead.

Censys introduced a new data model for describing hosts, certificates, and web properties on the internet in the Censys Platform. This new data model is different from the one available in Legacy Search and features many improvements and additions. Queries and workflows that were used in Legacy Search need to be modified to return similar results in the Censys Platform.

Some of the most prominent changes include:

• A new domain-specific language and syntax, Censys Query Language (CenQL), for querying the Censys Platform datasets.
• Virtual hosts are now represented by web properties to describe and organize data for internet assets that respond to name-based scans.
• Additional context about web asset software, hardware, operating system, threats, and more to provide actionable information on what exactly mapped services and devices are, how they are configured, whether they are vulnerable, whether they are malicious, and where they live.
  • Threat-related data, including data that was previously associated with the C2 label in Legacy Search datasets, is accessible to Enterprise organizations that have purchased the Threat Hunting module.
• host, cert, or web have been prepended to all parsed data fields. These values indicate whether the field is present on a host, certificate, or web property asset.
• Many values related to software or hardware that were previously present in the label field in Legacy Search can now be found instead in software and software.components fields for hosts and web properties.

Censys offers tiered data access solutions for a wide range of users, from hobbyists to enterprise security teams. The Starter tier is designed to provide comprehensive internet visibility and actionable insights. You can search and view basic & advanced protocols and services that unlock deeper data and view one week of host history, excluding ICS protocols. Raw data can be viewed and downloaded.

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)
• Cobalt strike, for red teams to test an org's vulnerabilities (Enterprise)

In addition to the new Platform, we also released the Censys Platform API. To seamlessly transition to the new API, please update the following:

• Base URL: There is a new base URL for the Censys Platform API.
• Access token: There is a new process to generate a Personal Access Token.
• Review any downstream applications that receive data from the API.

For more information about these changes, see Get Started.
