 Vulnerabilities List - JSON report
 
-### Sample Scan Data
+Invicti is a web application security scanner available as Invicti 
+Enterprise (cloud-based) and Invicti Standard (on-premise). It identifies 
+vulnerabilities through automated crawling and attack simulation, producing 
+confirmed and unconfirmed findings with proof of exploit where available.
+
+DefectDojo supports two methods of ingesting Invicti findings:
+
+1. **File-based import** - Export a Vulnerabilities List in JSON format 
+   from Invicti and upload it manually into DefectDojo
+2. **Native integration** - Configure Invicti Enterprise to push findings 
+   directly to DefectDojo automatically after each scan
+

+
+## File-Based Import
+
+### How to Export from Invicti Enterprise
+
+1. Log in to Invicti Enterprise
+2. Go to **Scans > Recent Scans** and select the relevant scan
+3. Select **Report**
+4. Under **Lists**, select **Vulnerabilities List**
+5. From the **Format** drop-down, select **JSON**
+6. Configure export options as needed:
+   - **Exclude Addressed Issues** — excludes findings already actioned 
+     in Invicti
+   - **Export Confirmed** - includes only findings verified with proof 
+     of exploit
+   - **Export Unconfirmed** - includes findings detected but not 
+     fully verified
+7. Select **Export** and save the JSON file
+8. Upload the file into DefectDojo under your chosen Engagement 
+   using **Import Scan > Invicti Scan**
+
+### Confirmed vs Unconfirmed Findings
+
+Invicti classifies findings in two ways:
+
+- **Confirmed** - Invicti verified the vulnerability with a proof of 
+  exploit. These are high-confidence findings and should be prioritized.
+- **Unconfirmed** - Invicti detected indicators of a vulnerability but 
+  could not fully verify it. These require manual review before acting 
+  on them.
+
+It is recommended to export both confirmed and unconfirmed findings and 
+use DefectDojo's **Active/Verified** flags to track review status rather 
+than filtering at export time. This preserves full visibility and avoids 
+losing findings from the vulnerability record.
+
+---
+
+## Native Integration (Invicti Enterprise)
+
+Invicti Enterprise supports direct integration with DefectDojo, allowing 
+findings to be pushed automatically after each scan without manual 
+file export.
+
+### Prerequisites
+- A DefectDojo API key with appropriate permissions
+- An existing Product and Engagement in DefectDojo to receive findings
+
+### Setup Steps
+
+1. Log in to Invicti Enterprise
+2. Go to **Integrations > New Integration**
+3. Under **Issue Tracking Systems**, select **DefectDojo**
+4. Enter a name for the integration
+5. Enter your DefectDojo URL, API key, Product ID, and Engagement ID
+6. Optionally add tags to help filter imported findings in DefectDojo
+7. Select **Save**
+8. Use **Test Credentials** to confirm the connection is working
+
+Once configured, Invicti Enterprise can be set to automatically push 
+findings to DefectDojo after each completed scan. This is recommended 
+for teams running regular or scheduled scans as it removes the manual 
+export step and keeps DefectDojo up to date in near real time.
+

+
+## Severity Mapping
+
+| Invicti Severity | DefectDojo Severity |
+|---|---|
+| Critical | Critical |
+| High | High |
+| Medium | Medium |
+| Low | Low |
+| Best Practice / Information | Info |
+
+Invicti also uses action-based priority labels in its reports such as 
+"Fix Immediately" and "Fix Soon". These do not map directly into 
+DefectDojo severity fields but can be used to inform triage decisions 
+when reviewing imported findings.
+
+---
+
+## Recommended Workflow for Enterprise Use
+
+For teams running Invicti Enterprise across multiple applications:
+
+1. **Use the native integration** rather than manual file exports to 
+   reduce operational overhead
+2. **Use Reimport** (not Import) for recurring scans on the same target 
+   to track finding status over time rather than creating duplicate records
+3. **Export Confirmed and Unconfirmed separately** if your team has a 
+   formal triage process — import confirmed findings as active and 
+   unconfirmed findings as requiring review
+4. **Set SLA thresholds** in DefectDojo aligned to Invicti severity 
+   levels so that Critical and High findings trigger appropriate 
+   remediation timelines automatically
+

+
+### Note on Deduplication for Large Scans
+
+Invicti can report the same vulnerability type across multiple URLs, 
+which means importing large scans without reviewing deduplication 
+settings can result in a high volume of findings that represent the 
+same underlying vulnerability class. To manage this:
+
+- Consider enabling **Apply Same Findings** in your Engagement settings 
+  to group similar findings
+- Use **Reimport** instead of Import for recurring scans to update 
+  existing findings rather than creating new ones each time
