Deep Search & Insights (DSI) brings Deepinfo's internet-wide data into the platform. It is not about your own
assets: you can look at registration trends, search every domain or CVE in Deepinfo's data, run a real-time
lookup on one target, or download bulk data files.

## Before You Start

- **Package:** DSI features are part of your package one by one: a search page, a lookup type or a feed can be
  included while another is not. A feed outside your package offers sample data only; other features show a
  notice that they are not included. See [What you can access](/guide/basics/packages-and-roles/).
- **Role:** Admin or Member.
- **Data:** none. DSI works on Deepinfo's data, not on your inventory.

## Where to Find It

**Sidebar:** **DEEP SEARCH & INSIGHTS** › **DOMAIN INTELLIGENCE** · [https://platform.deepinfo.com/app/dsi/domain-intelligence](https://platform.deepinfo.com/app/dsi/domain-intelligence)

**DEEP SEARCH & INSIGHTS** is the green group heading in the sidebar. The heading is not a link and there is no
DSI start page: open one of its items. The header breadcrumb starts with **DSI**, for example
**DSI / DOMAIN SEARCH**.

| Sidebar item | What it does | Guide page |
|---|---|---|
| **DOMAIN INTELLIGENCE** | Statistics on domain registrations, TLDs and keywords | [Domain intelligence](/guide/dsi/domain-intelligence/) |
| **DOMAIN SEARCH** | Search Deepinfo's domain data with filters; open any domain's details | [Search domains](/guide/dsi/domain-search/), [Domain details and reverse lookups](/guide/dsi/domain-details/) |
| **VULNERABILITY INTELLIGENCE** | Statistics on CVEs, weaknesses (CWE) and the latest CVEs | [Vulnerability intelligence](/guide/dsi/vulnerability-intelligence/) |
| **VULNERABILITY SEARCH** | Search the CVE database with filters; open a CVE | [Search vulnerabilities](/guide/dsi/vulnerability-search/) |
| **INSTANT LOOKUP** | Real-time Whois, DNS, SSL, Webdata, Technology, Screenshot and Port Scanner lookups | [Run instant lookups](/guide/dsi/instant-lookup/) |
| **FEEDS** | Download daily and full domain and subdomain files | [Download data feeds](/guide/dsi/feeds/) |

Opening [https://platform.deepinfo.com/app/dsi](https://platform.deepinfo.com/app/dsi) takes you to
**Domain Search**. Older links to `/app/explore` open **Domain Search** too.

## Page Tabs in Domain Search, Vulnerability Search and Instant Lookup

These pages work like a browser: each search, domain, CVE or lookup can have its own page tab, and you
switch between them above the page.

- **Open a tab:** a search result or a suggestion can open in a new page tab (**OPEN IN NEW TAB**). In Instant
  Lookup, the **+** button adds a tab for the lookup type you pick.
- **Manage tabs:** right-click a tab for **Duplicate**, **New Tab to The Right**, **Close Tab**,
  **Close Other Tabs** and **Close Tabs to the Right**. The menu also lists **Add Tab to Saved Search**, which has
  no effect.
- **Tabs are kept in this browser.** Your open tabs, with their queries and the last Instant Lookup result, are
  kept in this browser for your user, so they are still there after a reload. They do not appear in another
  browser or on another computer. Close a tab to remove it.

Saving searches is not available: **SAVED SEARCH** and **SAVE THIS SEARCH** are visible but have no effect.

## Filters

Domain Search and Vulnerability Search share one filter builder. The chips under the search box open groups of
fields; each rule you add is **MUST**, **MUST NOT** or **SHOULD** match. **SEARCH** runs the query, and the
**FILTERS APPLIED** bar then lists the rules in use, with **CLEAR FILTERS**. **HIDE FILTERS** folds the chips
away. See [Search, filter and export lists](/guide/basics/lists-filters-and-exports/) for the rule model; the
API search endpoints use the same one (see [Search and filters](/getting-started/search-and-filters/)).

## Pages in This Section

2. [Search domains](/guide/dsi/domain-search/): query the domain data and export results.
3. [Domain details and reverse lookups](/guide/dsi/domain-details/): one domain's full record.
4. [Vulnerability intelligence](/guide/dsi/vulnerability-intelligence/): CVE statistics, CWE categories, latest CVEs.
5. [Search vulnerabilities](/guide/dsi/vulnerability-search/): query the CVE database.
6. [Run instant lookups](/guide/dsi/instant-lookup/): one target, in real time.
7. [Download data feeds](/guide/dsi/feeds/): daily and full data files.
