Active scanning allows you to find more assets as well as vulnerabilities while passive scanning is stealthier but only limited to asset discovery. The Attaxion scanner supports two scan modes—Active and Passive. The scan mode determines which discovery utilities the Attaxion scanner will use.  The default scan mode is active, but you can switch between the different modes to optimize the scanning to your needs. You may also turn off the scanner if you need to pause scanning for all your assets or for certain assets only. ### Different Types of Scanning Profiles ![active-and-passive-modes-info](https://support.attaxion.com/hs-fs/hubfs/active-and-passive-modes-info.png?width=688&height=306&name=active-and-passive-modes-info.png) #### **Passive Scanning** Passive scanning includes the following scanning methods: - WHOIS Lookup - Passive Subdomains Lookup - Reverse DNS Lookup - Reverse WHOIS Lookup - IP Geolocation Lookup - IP Netblocks Lookup - Cloud Providers Scanner - DNS Lookup In passive mode, the Attaxion scanner doesn't discover open ports, SSL certificates, or vulnerabilities, limiting the discovered asset types to subdomains, IPs, CIDRs, and emails. This method is unlikely to trigger an organization's intrusion detection system and other defensive solutions. However, because no vulnerability data is retrieved in passive mode, the [Total score](https://support.attaxion.com/total-score-what-it-means-and-how-it-is-calculated?hsLang=en) on the Dashboard menu will be 0 (i.e., information unknown). In addition to all methods employed in passive scanning, active scanning relies on the following discovery tools: - Vulnerability Scanner - Web Crawler - Active Subdomains Scanner - SSL Lookup - Port Scanner - Screenshot Lookup This type of scanning discovers ports and scans for vulnerabilities, as well as adds additional methods for subdomain enumeration. Intrusion detection systems are much more likely to easily detect active scanning. ### **How to Switch Between Scanning Modes in Attaxion** To switch from one scanning mode to another, click your account name in the upper-right window. On the **General** tab, scroll down until you find the **Global scanner settings**. From there, you can choose between **Active** and **Passive** mode by clicking the respective buttons. ### ![Global scanner settings (1)](https://support.attaxion.com/hs-fs/hubfs/Global%20scanner%20settings%20(1).png?width=688&height=65&name=Global%20scanner%20settings%20(1).png) The setting will be applied immediately to all your assets without having to save or confirm anything. #### **Choosing the Scanning Mode for Assets Individually** Attaxion allows you to set scanning modes on a per-asset basis. That means that the scanner can have one global mode, but some assets may have different scanning modes. To change the scanning mode for an asset, open its [**Asset details**](https://support.attaxion.com/asset-details-view-explained?hsLang=en) window by clicking the asset name. Click **Actions** from the top-right corner and select **Update scanner settings** from the drop-down menu. #### ![1 (2)](https://support.attaxion.com/hs-fs/hubfs/1%20(2).png?width=688&height=198&name=1%20(2).png) There are four options—**Disabled**, **Inherit**, **Passive**, and **Active**. **Inherit** is the default mode, meaning the asset’s scanning mode will be the same as its root asset or global scanner mode. All newly created root assets will inherit the scan mode from the global configuration by default. Also, Port assets will always inherit the scan mode from the parent IP address asset. **Disabled** will exclude the asset from scanning. ![](https://support.attaxion.com/hs-fs/hubfs/asset-scan-profile-change-png.png?width=688&height=206&name=asset-scan-profile-change-png.png) Click your preferred mode to instantly change the scanning mode for the specific asset. - [Getting Started](https://support.attaxion.com/getting-started?hsLang=en#main-content) - [FAQs](https://support.attaxion.com/getting-started?hsLang=en#faqs) - [Start Here](https://support.attaxion.com/getting-started?hsLang=en#start-here) - [Assets and Attack Surface](https://support.attaxion.com/assets-and-attack-surface?hsLang=en#main-content) - [Asset inventory](https://support.attaxion.com/assets-and-attack-surface?hsLang=en#asset-inventory) - [Root Assets and Discovery](https://support.attaxion.com/assets-and-attack-surface?hsLang=en#root-assets-and-discovery) - [Ports and Technologies](https://support.attaxion.com/assets-and-attack-surface?hsLang=en#ports-and-technologies) - [Scanning](https://support.attaxion.com/scanning?hsLang=en#main-content) - [Scanning Modes and Settings](https://support.attaxion.com/scanning?hsLang=en#scanning-modes-and-settings) - [Investigation](https://support.attaxion.com/scanning?hsLang=en#investigation) - [Prioritization](https://support.attaxion.com/scanning?hsLang=en#prioritization) - [Reporting](https://support.attaxion.com/scanning?hsLang=en#reporting) - [Account, Team, and Billing](https://support.attaxion.com/account-team-and-billing?hsLang=en#main-content) - [Account and Team Settings](https://support.attaxion.com/account-team-and-billing?hsLang=en#account-and-team-settings) - [Trials and Plans](https://support.attaxion.com/account-team-and-billing?hsLang=en#trials-and-plans) - [Integrations](https://support.attaxion.com/integrations?hsLang=en#main-content) - [REST API](https://support.attaxion.com/integrations?hsLang=en#rest-api) - [Native Integrations](https://support.attaxion.com/integrations?hsLang=en#native-integrations) - [Monitoring and Brand Protection](https://support.attaxion.com/monitoring-and-brand-protection?hsLang=en#main-content) - [Infrastructure Monitoring](https://support.attaxion.com/monitoring-and-brand-protection?hsLang=en#infrastructure-monitoring) - [Brand Protection](https://support.attaxion.com/monitoring-and-brand-protection?hsLang=en#brand-protection) - [MSSP](https://support.attaxion.com/mssp?hsLang=en) - [Product Updates](https://support.attaxion.com/product-updates?hsLang=en) - [Attaxion Quick Start Guide](https://support.attaxion.com/attaxion-quick-start-guide) - [Working with Attaxion and Using Additional Features](https://support.attaxion.com/working-with-attaxion-and-using-additional-features) [![Chill listening crop-3](https://support.attaxion.com/hs-fs/hubfs/Lettermark-White-Background.png?width=23&height=24&name=Lettermark-White-Background.png "Chill listening crop-3")](http://attaxion.com) Copyright © 2026, Attaxion LLC  All rights reserved.
