Discovery rules look for assets related to the ones you already monitor. What they find waits on the
**DISCOVERED ASSETS** tab until you decide: add it to your inventory, or ignore it.

## Before You Start

- **Package:** External Attack Surface Management (EASM).
- **Role:** Admin or Member.

## Where to Find It

**Sidebar:** **EXTERNAL ATTACK SURFACE MANAGEMENT** › **ASSETS** › **DISCOVERY** · **Tab:** **DISCOVERED ASSETS** · [https://platform.deepinfo.com/app/easm/discoveries](https://platform.deepinfo.com/app/easm/discoveries)

Discovery has three in-page tabs:

| Tab | What it holds | Deep link |
|---|---|---|
| **OVERVIEW** | Summary cards (see [The OVERVIEW tab](#the-overview-tab)) | [/app/easm/discoveries/overview](https://platform.deepinfo.com/app/easm/discoveries/overview) |
| **DISCOVERED ASSETS** | The assets waiting for review, described on this page | [/app/easm/discoveries](https://platform.deepinfo.com/app/easm/discoveries) |
| **SETTINGS** | **Smart Discovery**, **Custom Rules** and **Other Settings**: the rules that find candidates; see [Tune smart discovery](/guide/easm/discovery-settings/) and [Create custom discovery rules](/guide/easm/custom-discovery-rules/) | [/app/easm/discoveries/settings/smart-discovery](https://platform.deepinfo.com/app/easm/discoveries/settings/smart-discovery) |

The **⋮** menu next to the **Discovery** title opens **IGNORED ASSETS** and **APPROVED ASSETS**.

Every discovered asset is **IN REVIEW**, **APPROVED** or **IGNORED**; see
[States](#states-colours-and-scores) below.

## Read the Screen

![The DISCOVERED ASSETS tab with the filter bar, the type tabs, the list with RULES badges and the row actions, numbered 1 to 4.](/img/guide/easm/discovery-01.png)

The header breadcrumb reads **EASM / ASSETS / DISCOVERY**.

1. **Filter bar:** **SEARCH**, the filter chips **ASSET**, **RULE** and **DISCOVERY**, and the list and quick
   view icons. Then the number of assets discovered (**N ASSETS DISCOVERED**) and **VIEW SETTINGS**.
2. **Type tabs** with counts: **ALL ASSETS**, **DOMAINS**, **SUBDOMAINS**, **IP ADDRESSES** and **WEBSITES**.
   Large counts are shortened, for example `12.5K`.
3. **The list**, 25 per page:
   - **ASSET**
   - **DISCOVERY DATE**, when the asset was last discovered
   - **RULES**, a badge with the full name of each rule that found the asset. A bulb icon marks a smart rule
     managed by Deepinfo; a custom rule of your own has a different icon. Hover over a badge to see its seed
     value, the input the rule started from.
4. **Row actions:** **ADD TO MY ASSETS** and an ignore button (an icon without text).

## Check an Asset Before You Decide

1. Select a row. The discovered-asset drawer opens.
2. Read **DISCOVERED DATE** and **RULES**. The drawer's icon tabs (**WHOIS** for domains, then **DNS**, **SSL**
   and **WEBSITE INFO**) hold the records captured on the discovery date. The info icon next to the date
   reminds you that they may have changed since.
3. To open the asset on its own page, select **OPEN IN NEW TAB**. The page has a **DISCOVERY** button to go
   back, and the same **ADD TO MY ASSETS** and **IGNORE** actions.

Subdomains have no **WHOIS** tab and open on **DNS**. IP addresses have no **DNS** tab.

## Add Assets to Your Inventory

1. On **DISCOVERED ASSETS**, select **ADD TO MY ASSETS** on the row. To add several, tick their rows first and
   use **ADD TO MY ASSETS** in the selection bar. To tick every row on the page, open the checkbox menu and
   select **SELECT THIS PAGE**; **CLEAR SELECTION** unticks them.
2. The **Add to Portfolio** confirmation shows how many assets you are adding ("portfolio" means your
   inventory). Select **ADD**, or **CANCEL** to go back.
3. After a few seconds the list refreshes. The assets are now in [Inventory](/guide/easm/asset-inventory/)
   and listed in **Approved Assets**.

## Ignore Assets

1. Select the ignore button on the row, or tick several rows and use **IGNORE** in the selection bar. You can
   also select **IGNORE** at the bottom of the drawer.
2. The **Confirmation** dialog shows how many assets you are ignoring. Select **IGNORE**, or **CANCEL**.
3. After a few seconds the list refreshes. The assets move to **Ignored Assets**.

## Undo an Ignore

1. Open **Ignored Assets**: **⋮** › **IGNORED ASSETS** next to the **Discovery** title.
2. Select **UNDO IGNORE** on the row, or tick several rows and use **UNDO IGNORE** in the selection bar. The
   drawer and the asset's page also have **UNDO IGNORE**.
3. Confirm with **REVERT**. The asset returns to review.

## Approved Assets and Ignored Assets

- **Approved Assets** (breadcrumb **EASM / ASSETS / DISCOVERY / APPROVED ASSETS**) lists the approved assets,
  with **ASSET**, **DISCOVERY DATE**, **APPROVED DATE** and **RULES**. It has the same filter chips and tabs
  as **DISCOVERED ASSETS**. It is a record: the list has no row or bulk actions, and the page of an approved
  asset has none either. Manage approved assets in [Inventory](/guide/easm/asset-inventory/).
- **Ignored Assets** lists what you ignored, with **ASSET**, **DISCOVERY DATE**, **IGNORED DATE**, **RULES**
  and **UNDO IGNORE**.

## Find Candidates

- **SEARCH** filters by asset name.
- The filter chips offer:
  - **ASSET**: Name, Organization, State
  - **RULE**: Name, Seed Value
  - **DISCOVERY**: Last Discovery Date, Ignore Date, Approve Date
- When Inventory's **SUBDOMAINS** tab is empty but discovery has found subdomains, its **GO TO DISCOVERY**
  button opens this list filtered to subdomains.

## The OVERVIEW Tab

![The Discovery OVERVIEW tab with the DISCOVERED ASSETS and STATE DISTRIBUTION cards and the recently approved and recently discovered asset tables.](/img/guide/easm/discovery-05.png)

| Card | What it shows |
|---|---|
| **DISCOVERED ASSETS** | How many discovered assets are waiting for review |
| **STATE DISTRIBUTION** | A pie of **IN REVIEW**, **APPROVED** and **IGNORED** |
| **RECENTLY APPROVED ASSETS** | **ASSET** and **APPROVED DATE** |
| **RECENTLY DISCOVERED ASSETS** | **ASSET** and **DISCOVERY DATE** |

## States, Colours and Scores

| State | Meaning | Where to find it |
|---|---|---|
| **IN REVIEW** | Found by a rule, waiting for a decision | **DISCOVERED ASSETS** |
| **APPROVED** | Added to your inventory | **Approved Assets** |
| **IGNORED** | Dismissed; it stays out of your inventory | **Ignored Assets** |

In the **STATE DISTRIBUTION** chart, **IN REVIEW** is dark blue, **APPROVED** blue and **IGNORED** light grey.

## Good to Know

- Actions take a few seconds to apply; the list refreshes on its own afterwards.
- A rule with **Auto Approval** turned on approves matching assets in review automatically. You set this on
  the **SETTINGS** tab; see [Tune smart discovery](/guide/easm/discovery-settings/).
- An asset you removed from Inventory can be found again by discovery and come back for review.
- The Discovery lists have no export button. The API can export discovered assets (see below).

## Do This With the API

- Search discovered assets: [Discovered Asset Search](/reference/easm/discovered-asset-search/)
- Get one: [Discovered Asset Detail](/reference/easm/discovered-asset-detail/)
- Approve: [Discovered Asset Approve](/reference/easm/discovered-asset-approve/)
- Ignore: [Discovered Asset Ignore](/reference/easm/discovered-asset-ignore/)
- Undo an ignore: [Discovered Asset Revert](/reference/easm/discovered-asset-revert/)
- Export (API only): [Discovered Asset Export](/reference/easm/discovered-asset-export/)
