# Critical Infrastructure

[Censys Core](https://docs.censys.com/docs/data-access-tiers-entitlements) customers may purchase the Critical Infrastructure module. This module includes industrial control system (ICS) and operational technology (OT) protocol data, screenshots, and an interactive dashboard for browsing parsed ICS data.

You can use the data and dashboard to identify exposed ICS and OT devices, services, and interfaces for triage and remediation.

## ICS protocols and data

The module grants access to ICS/OT-specific protocols and all related scan data. This data can be viewed in the web app or retrieved via API.

## ICS screenshots

In addition to the ICS metadata available with the protocol license, screenshots are captured for the following ICS services whenever they are scanned by Censys. <Anchor target="_blank" href="https://docs.censys.com/docs/platform-web-screenshots#/">Learn more about screenshots here</Anchor>.

* `CMORE_HMI`
* `REDLION_CRIMSON`
* `SCADA_VIEW`

### Extracted text

Text that is extracted from screenshots using optical character recognition (OCR) is indexed and searchable in `extracted_text` data fields. Use these fields to search for words of interest, <Anchor target="_blank" href="https://platform.censys.io/search?q=host.services.screenshots.extracted_text%3A+%22admin%22">such as `admin`</Anchor>, or <Anchor target="_blank" href="https://platform.censys.io/search?q=host.services.screenshots.extracted_text%3A+%22windows+server+2012%22">a vendor name, product name, machine information, or location information</Anchor>.

## Critical Infrastructure dashboard

The <Anchor target="_blank" href="https://platform.censys.io/explore/critical-infrastructure">Critical Infrastructure dashboard in the Platform web UI</Anchor> is a filterable view of ICS/OT assets identified by Censys scans. To access the dashboard, click the Critical Infrastructure icon (a drop with a lightning bolt inside) in the left-hand navigational bar.

<Image src="https://files.readme.io/2d7506959f01d5c3091099a63b472c6e95fae2b0ff02662acf82b3529d696658-Screenshot_2026-03-09_at_2.59.55_PM.png" align="center" border={true} />

Use the tabs at the top to switch between viewing data for hosts and web properties.

Use the **Location** (for hosts), **Vendor**, **Product**, and **Protocols** drop downs to filter the entire dashboard to focus on countries, vendors, products, and protocols of interest.

The **Screenshots** section displays screenshots captured from services that meet your filter criteria. Use the **Top Extracted Text** section to find exposed services based on text pulled from screenshots.

The **Top 10 Metrics** section breaks down the top countries (for hosts), vendors, products, and protocols present in your filtered results.

To see the full list of assets that meet your filter criteria, scroll down to the **Hosts** or **Web Properties** section below the **Top 10 Metrics** window. Click on a host or web property entry to see its full details.
