PI Integration Audit
A focused review of your PI Web API integration by specialists who have seen what works and what breaks in production. Get a clear report on what is working, what is risky, and what to fix first.
What you get
Architecture review
We review your integration architecture, data flow, and PI Web API usage patterns. Identify bottlenecks, single points of failure, and scalability limits.
Security assessment
Evaluate authentication method, certificate handling, credential storage, PI identity mapping, and network security posture. Aligned with IEC 62443 where applicable.
Code quality review
Assess error handling, retry logic, pagination, batch usage, digital state handling, quality flags, and overall code structure against PI Web API best practices.
Written report with code fixes
Receive a prioritized findings report with severity ratings (Critical, High, Medium, Low), specific code examples showing the fix, and a suggested remediation sequence.
What we look for
| Category | What we check |
|---|---|
| Authentication | Auth method choice, credential storage, session management, Kerberos delegation |
| SSL / Certificates | Certificate validation, CA bundle trust chain, verify=False usage |
| Connection management | Session reuse, connection pooling, socket exhaustion risk |
| Error handling | Retry logic, backoff strategy, partial failure handling, error classification |
| Batch usage | Chunk size, sub-request error checking, memory impact |
| Pagination | Truncation detection, time-based pagination, continuation tokens |
| Data handling | Digital state handling, quality flags, timezone awareness, selectedFields |
| Observability | Logging, health checks, metrics, alerting |
| Deployment | Environment config, secrets management, container readiness |
Common findings
These are the issues we find most often. If any sound familiar, an audit will help quantify the risk and provide the fix.
SSL verification disabled in production (verify=False)
Credentials stored in plaintext config files or source code
No retry logic for transient failures (502, 503, 504)
Batch responses checked at top level only -- sub-request failures silently ignored
New HttpClient/Session created per request, causing socket exhaustion
No selectedFields parameter -- transferring 5x more data than needed
How it works
Share your integration
Send us your codebase, architecture diagram, or a walkthrough of your PI Web API integration. We sign an NDA if needed. We typically need read access to the repository and a brief call to understand the context.
We review
Our PI Web API specialists review your integration against production best practices, security standards, and performance patterns. We test with real PI Web API behavior in mind, not just code quality.
You get a report
Within 5 business days, you receive a written report with findings rated by severity, specific code fixes for each issue, and a recommended remediation order.
Optional: We implement the fixes
If you want hands-on help implementing the recommendations, we can scope a follow-up engagement. Many teams do the high/critical fixes themselves using our code examples and engage us for the architectural changes.
Who this is for
- You have an existing PI Web API integration that needs hardening before going to production
- You inherited a PI integration from a previous team or vendor and need to understand its state
- You need to meet internal security or compliance requirements (IEC 62443, SOC 2)
- Your PI data pipeline has reliability issues and you want an expert second opinion
- You are considering a migration from AF SDK to PI Web API and want to validate your approach
Get started
Request an integration audit
Tell us about your integration and we will scope the audit. Most audits are completed within one week. The scoping conversation is free and typically takes 30 minutes.
