# Scan Engine definitions

# Scan Engine definitions {#ariaid-title1}

Release version: Zurich  
Updated October 29, 2025  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
The Scan Engine uses a large set of definitions to correct coding and workflow findings in real time and perform scans across your entire instance to detect existing findings.

## Pre-defined definitions {#scan-engine-definitions__section_kwm_mth_dhc}

There are various types of definitions available as a baseline in the Impact Scan Engine.
{#scan-engine-definitions__table_zby_my2_m2c__entry__2}

| Category | Description |
|-|-|
| Manageability | Measures the extent to which ServiceNow instances, applications, or infrastructure can be effectively monitored, configured, and maintained. |
| Performance | Measures the efficiency of a ServiceNow instance, encompassing aspects such as speed, responsiveness, resource utilization, and overall dependability |
| Security | Measures implementation of protocols across a ServiceNow instance to prevent unauthorized access, data breaches, cyber attacks, and potential vulnerabilities |
| Upgradeability | Assesses the ease of enhancing a ServiceNow instance or application with new features, improvements, security patches, or compatibility adjustments |
| User Experience | Evaluates the quality of user interactions with applications. Considers the ease of use, efficiency, design, responsiveness, accessibility, and its emotional and functional impact. |
[Table 1. Scan Engine definition categories]

For more information, see [Configure Scan Engine parameters](https://www.servicenow.com/docs/2zlFyhVtwSoxB22F1frkEw "Configure the primary scanning capabilities and configuration options for scheduled, on-demand, and real-time scans.").

## Custom definitions {#scan-engine-definitions__section_sbn_55h_dhc}

Users can create their own custom definitions. For more information, see [Create custom Scan Engine definitions](https://www.servicenow.com/docs/fM_Z4oUJgVE11cEiECW3FQ#create-scan-engine-definitions "The Scan Engine contains preexisting base system definitions. However, if your organization has specific scanning needs not met by these definitions, you can create your own.").  
Note:  
The number of custom definitions that is permitted varies based on your Impact package. For more information, see [Impact packages](https://www.servicenow.com/docs/RkKSHKEDy~3SI03Lmh7tcw "ServiceNow Impact packages comprise support tools, self-help resources, human-led engagements, discounts, and additional benefits made available to you depending on the level of Impact package procured.").

## Scan Engine definition suites {#scan-engine-definitions__section_ybx_vvh_dhc}

Definition suites are groupings of similar definitions that allow administrators to target specific areas or functions of code during scans. This is useful as it allows scanning of the entire instance or all definitions. Admins can
focus on a suite that represents a logical category (for example, JavaScript naming conventions, ITOM workflows, security hardening, and so on). This improves efficiency and precision in code quality checks.

By default, the following suites are available:

* Scan Engine
* JavaScript Naming Conventions
* Scoped Application
* ITOM
* Workflow Engine
* Security and Instance Hardening
* IL4 (Impact Level 4)
* HR Scoped Applications
* Artificial Intelligence Readiness

Note:  
Only users with the `sn_se.scan_engine_admin_role` role can modify existing suites and their relationship with their definitions.

For more information, see [Create Scan Engine definition suites](https://www.servicenow.com/docs/usc7Ar2r48TWwFlrZLRvcQ#create-scan-engine-definition-suites "Follow these steps to create Scan Engine definition suites.").
