External Attack Surface Management (EASM) detects the software, frameworks and services your assets run, for example a web server, an operating
system or a JavaScript library. The technology list shows each one with its versions, the latest
version, how many assets use it and its known vulnerabilities.

## Before You Start

- **Package:** EASM.
- **Role:** Admin or Member.

## Where to Find It

**Sidebar:** **EXTERNAL ATTACK SURFACE MANAGEMENT** › **TECHNOLOGIES** · **Tab:** **TECHNOLOGIES LIST** · [https://platform.deepinfo.com/app/easm/technologies](https://platform.deepinfo.com/app/easm/technologies)

The **OVERVIEW** tab ([https://platform.deepinfo.com/app/easm/technologies/overview](https://platform.deepinfo.com/app/easm/technologies/overview))
holds the summary cards, and **INSIGHTS** the analysis; see [Technology insights](/guide/easm/technology-insights/).

## Read the Screen

![The TECHNOLOGIES LIST tab with the filter bar, the result line and the first rows of the list, numbered 1 to 3.](/img/guide/easm/technologies-01.png)

1. **Filter bar:** **SEARCH** (by technology name) and the filter chips **TECH. NAME**, **TECH. CATEGORY**,
   **AFFECTED ASSET COUNT**, **VERSIONS**, **VERSION SCOPE**, **LATEST VERSION** and **TOTAL VULN. COUNT**.
2. **Result line:** the number of technologies found, **EXPORT** and **VIEW SETTINGS**.
3. **The list:**

| Column | What it shows |
|---|---|
| **TECHNOLOGY** | The technology's name |
| **CATEGORY** | Its category, for example a JavaScript library |
| **VERSION** | The versions found on your assets, one per line |
| **LATEST VERSION** | The latest known version |
| **ASSETS** | How many of your assets use it |
| **VULNERABILITIES** | Its known vulnerabilities |

### The OVERVIEW Tab

| Card | What it shows |
|---|---|
| **TOTAL TECHNOLOGIES** | The number of technologies, with the change over the **LAST 30 DAYS** |
| **TOP CATEGORIES** | The categories with the most technologies |
| **MOST USED TECHNOLOGIES** | Technologies found on many of your assets |
| **VULNERABILITY STATS** | The vulnerabilities of your technologies, per severity |
| **OUTDATED TECHNOLOGIES** | Technologies with an out-of-date version: **TECHNOLOGY**, **VERSION**, **LATEST VERSION** |
| **MOST VULNERABLE TECHNOLOGIES** | Technologies with the most vulnerabilities: **TECHNOLOGY**, **VULNERABILITIES** |

## Find Outdated Technologies

1. Select the **VERSION SCOPE** chip.
2. Choose **Out of Date** as the value and select **APPLY**.

The list now shows only the technologies with an out-of-date version on your assets. The **ASSETS** and
**VULNERABILITIES** columns then count only the out-of-date use. To go back, choose **All**.

## Filter and Sort the List

- **SEARCH** matches the technology name.
- Each filter chip takes one condition, with no **Must** / **Must Not** / **Should** choice. For example,
  **VERSION SCOPE** takes **Equal** and a **Value**. Select **APPLY**, or **CANCEL** to close it.
- Select a column header to sort: once for descending order, again for ascending, and a third time to go back
  to the default order. All six columns sort.
- **VIEW SETTINGS** › **View Options** › **Sort By** sorts by **Technology**, **Categories**,
  **Affected Asset Count**, **Versions**, **Latest Versions** or **Vulnerability Stats**. **Result Per Page**
  sets 25, 50, 75 or 100 rows.

## Open a Technology

Select a row to open the technology drawer. The tabs on its left edge are icons; hover over one to see its name.
**OPEN IN NEW TAB** opens the full technology page; see [Technology details](/guide/easm/technology-details/).

![The technology drawer on its ASSETS tab listing each asset with its identified version.](/img/guide/easm/technologies-02b.png)

| Tab | What it shows |
|---|---|
| **OVERVIEW** | **CATEGORY**, the **VERSION** list, **LATEST VERSION**, a description, **INSIGHTS** with the number of assets that use it, and **FINDINGS** with its vulnerabilities |
| **ASSETS** | Every asset that uses it, each with its **IDENTIFIED VERSION** |
| **VULNERABILITIES** | The technology's known CVEs, each with **PUBLISHED DATE** and **LAST MODIFIED DATE** |
| **TECHNOLOGY INFO** | **DESCRIPTION**, **OFFICIAL WEBSITE**, the **EOL** (end-of-life) table and the list of the technology's CVEs |

## Export the List

1. Select **EXPORT**. The **DOWNLOAD** dialog opens.
2. Under **RECORDS**, choose **ALL**, or **FILTERED** for only the technologies that match your filters
   (offered when filters are applied).
3. Under **FILE FORMAT**, choose **CSV** or **JSON**, then select **DOWNLOAD**.

For the dialog's options, see [Search, filter and export lists](/guide/basics/lists-filters-and-exports/).

## Good to Know

- **TECHNOLOGY INFO** describes the technology in general, not only its use on your assets.
- In the drawer, the CVE cards can show the published date as **LAST MODIFIED DATE**. The technology page's
  **VULNERABILITIES** tab shows both dates correctly.
- Technologies also appear per asset, on an asset's **TECHNOLOGIES** tab; see
  [Investigate an asset](/guide/easm/asset-details/).
