## Custom Telemetry

![Custom Telemetry](/images/articles/powerapps/2025-08-11-powerapps-security-data-loss-prevention-dlp-governance-ctx-1.svg)

**Application Insights integration:**







```powerapps
// App.OnStart - Initialize telemetry
Set(varAppInsightsKey, "instrumentation-key");
Set(varSessionID, GUID());
Set(varAppVersion, "2.1.0");

// Track app launch
Trace(
```text
"AppLaunched",
TraceSeverity.Information,
{
    SessionID: varSessionID,
    AppVersion: varAppVersion,
    UserEmail: User().Email,
    Environment: "Production"
}```
)

// Track screen views
// Screen1.OnVisible
Trace(
```text
"ScreenViewed",
TraceSeverity.Information,
{
    ScreenName: "Dashboard",
    SessionID: varSessionID,
    Timestamp: Now()
}```
)

// Track errors
// Button.OnSelect
IfError(
```text
Patch(Cases, Defaults(Cases), formData),
Trace(
    "CaseCreationFailed",
    TraceSeverity.Error,
    {
        ErrorMessage: FirstError.Message,
        UserEmail: User().Email,
        SessionID: varSessionID
    }
)```
)

Security Best Practices

1. Principle of Least Privilege: Grant minimum necessary permissions
2. Environment Isolation: Separate dev/test/prod with strict DLP
3. Service Principals: Use for production apps, not personal accounts
4. Regular Audits: Review app usage and access logs monthly
5. Connector Governance: Approve custom connectors before use
6. Conditional Access: Enforce MFA and device compliance
7. Data Classification: Label sensitive data, restrict sharing

Compliance Scenarios

GDPR Compliance

Data subject access requests:

## Find all apps accessing user data
$userEmail = "user@contoso.com"





$apps = Get-AdminPowerApp | Where-Object {
```powershell
$connections = Get-AdminPowerAppConnection -AppName $_.AppName
$connections | Where-Object {
    $_.CreatedBy.userPrincipalName -eq $userEmail
}```
}

## Export user data from Dataverse

![Export user data from Dataverse](/images/articles/powerapps/2025-08-11-powerapps-security-data-loss-prevention-dlp-governance-ctx-3.svg)
$records = Get-CrmRecords -conn $crmConn -EntityLogicalName contact `
```text
-FilterAttribute emailaddress1 -FilterOperator eq -FilterValue $userEmail

Delete user data (right to be forgotten)

Remove-CrmRecord -conn $crmConn -EntityLogicalName contact -Id $records[0].contactid

Architecture Decision and Tradeoffs

When designing low-code development solutions with Power Apps, consider these key architectural trade-offs:

Recommendation: Start with the managed approach for most workloads and move to custom only when specific requirements demand it.

Cost and Performance Notes

• Primary Cost Drivers: Compute tier, storage volume, and network egress
• Optimization Levers: Right-size resources, use reserved instances or savings plans, and review Azure Advisor recommendations regularly
• Performance Baseline: Define SLAs, latency targets, and throughput thresholds before going live
• Scaling Strategy: Use auto-scale rules and monitor utilisation to balance cost and responsiveness

Validation and Versioning

• Last Validated: April 2026
• Tested With: Current generally-available Power Apps APIs and SDKs
• Known Constraints: Check regional availability and service limits before production deployment
