It helps identify, prioritize, and resolve risks before they impact users by scanning thousands of configuration points and providing actionable findings, trends, and a consolidated Instance Health Score. Show full answer Show less ## Key Features * **Comprehensive Health Evaluation:** Performs hundreds of checks across five categories---Security, Performance, Manageability, Upgradeability, and User Experience---to assess overall instance health. * **Two Scan Types:** * **Full Scan:** Evaluates every record in scope against all active definitions; only one full scan runs at a time to protect performance. * **Delta Scan:** Focuses on changes since the last scan to efficiently update health status. The Scan Engine automatically selects the appropriate scan type. * **Findings Management:** Violations become findings with enforcement levels (block, warn, inform) and risk ratings to prioritize resolution. * **AI-Assisted Resolution:** Integration with ServiceNow Otto provides AI-suggested fixes for findings, available during coding or in bulk from scan results. * **Role-Based Dashboards:** Tailored views for different roles (executives, developers, etc.) to monitor platform health trends and prioritize actions effectively. ## Benefits for ServiceNow Customers * Proactively identify and mitigate risks such as security breaches, performance issues, and upgrade blockers before they affect production. * Reduce technical debt and optimize instance performance with real-time guidance and continuous monitoring. * Make informed decisions using a single Instance Health Score that aggregates risk from multiple domains. * Improve operational efficiency by automating issue resolution with AI suggestions and exception management. * Maintain transparency and accountability through role-specific dashboards and trend tracking. ## Next Steps To effectively use the Scan Engine, initiate scans as needed, monitor scan progress, review and act on findings, and leverage AI tools for remediation. Utilize dashboards to track health trends and ensure ongoing compliance with best practices. For detailed procedures and configuration, refer to documentation on scan management, health score calculations, AI remediation, and dashboard usage. The Scan Engine is the diagnostic engine behind Impact Platform Health. It continuously evaluates your ServiceNow instance against leading practice definitions so you can find, prioritize, and resolve issues before they affect your users. With thousands of configuration points across an instance, it is difficult to know where risk is hiding. The Scan Engine solves this by scanning your instance against a library of leading practice definitions, then surfacing the results as actionable findings, trends, and consolidated Instance Health scoring. Using the Scan Engine, you can: * Understand instance health through hundreds of leading practice checks across five categories. * Reduce technical debt and optimize performance before issues reach production. * Prevent common implementation missteps with real-time, in-context guidance. * Track trends over time with role-based dashboards and a comparable, repeatable health score. {#scan-engine-overview__ul_scan_engine_value} ## Why scan your instance {#scan-engine-overview__section_why_scan} Every scan protects your instance against risk that would otherwise go unnoticed until it causes an outage, a failed upgrade, or a security incident. The Scan Engine supports two overall scan types so you can choose the right depth for the moment. {#scan-engine-overview__table_scan_types__entry__2} | Scan type | When it runs | |-|-| | Full scan | Evaluates every record in scope against every active definition. Only one full scan can run on an instance at a time, protecting instance performance. | | Delta scan | Evaluates only what has changed since the last scan. The Scan Engine determines automatically whether a full or delta scan is needed, reducing the decisions you have to make. | [Table 1. Full and delta scans] {#scan-engine-overview__table_scan_types} For details on initiating, monitoring, and canceling scans, see [Full and delta scans](https://www.servicenow.com/docs/0uD14YiK3EqjCn1q5bOtqw "The full and delta instance scan feature with Impact Platform Health Scan Engine enables ServiceNow administrators and developers to initiate, monitor, and manage instance health."). ## Health scores and definitions {#scan-engine-overview__section_health_score} Every finding traces back to a definition, and every definition belongs to one of five categories. {#scan-engine-overview__table_categories__entry__2} | Category | What it covers | |-|-| | Security | Breach risk, compliance violations, and access-control vulnerabilities. | | Performance | Issues that affect responsiveness and compound if left unaddressed. | | Manageability | Administration and supportability of the instance. | | Upgradeability | Configurations that can block or delay ServiceNow release upgrades. | | User experience | Adoption and satisfaction factors with lower overall urgency. | [Table 2. Scan Engine categories] {#scan-engine-overview__table_categories} These five categories roll up into a single Instance Health Score, a 0--100 metric weighted by how much risk each category represents. For the full calculation model, see [Platform Health score calculation model](https://www.servicenow.com/docs/F7qiIl3J44Nkm7noFnyyzQ "Your Platform Health score is the foundation for understanding instance risk. The score reflects platform risk through a four-step, category-weighted calculation that combines findings into a single 0–100 health metric."). ## Working with findings {#scan-engine-overview__section_working_with_findings} After a scan completes, every violation of a definition becomes a finding. Reviewing and resolving findings is a two-phase process. 1. Review results, monitor an active scan or open a completed scan record to see its status, duration, and batch progress. 2. Work findings, open individual findings to understand their enforcement level and impact, then apply fixes or submit exceptions for review. {#scan-engine-overview__ol_findings_flow} Each finding is evaluated along two dimensions, its enforcement level, which determines whether the system blocks, warns, or informs. Also its risk rating, which determines the order findings should be addressed within that level. For the full breakdown of enforcement levels and finding record fields, see [View scan results for Scan Engine](https://www.servicenow.com/docs/NeP4LeOh5nlKmcKWc~8rSQ "You can view scans in real-time as they run or after they're completed. "). For most findings, resolution does not have to be manual. With ServiceNow Otto, you can generate an AI-suggested fix as you code or in bulk from completed scan results. For details on both workflows, see [Prevent and resolve technical debt with AI](https://www.servicenow.com/docs/bKaBdGWz09a5uJMUM89lOQ "Use the Scan Engine and ServiceNow Otto AI agent to prevent technical debt as you code or remediate existing findings from completed scans."). ## Tracking trends over time {#scan-engine-overview__section_dashboards} Role-based dashboards give every persona, from executives to developers, a view of platform health suited to their responsibilities, refreshed automatically after each scan. For details on dashboard roles and interactivity, see [Track Platform Health trends](https://www.servicenow.com/docs/qj53y~Ci7~ZBW5r_LVoDkQ "Analytics Dashboards provide a graphical way to view detailed information relating to findings, both pending and resolved, with the Scan Engine. The dashboards are role-based, allowing for persona-based views of information. They display  key metrics,  charts, and  trend analysis."). **Related concepts** * [Full and delta scans to monitor instance health](https://www.servicenow.com/docs/0uD14YiK3EqjCn1q5bOtqw "The full and delta instance scan feature with Impact Platform Health Scan Engine enables ServiceNow administrators and developers to initiate, monitor, and manage instance health.") * [Instance Health Score calculation model](https://www.servicenow.com/docs/F7qiIl3J44Nkm7noFnyyzQ "Your Platform Health score is the foundation for understanding instance risk.
