SEva — AI Technical Support Powered by PII Firewall ​

SEva (SupportEva) is the AI technical support agent built into the PII Firewall Developer Console.

But SEva is more than a support chatbot.
SEva runs on the full PII Firewall stack. Every time you ask SEva a question, you are experiencing PII Firewall's complete protection pipeline in action — in real time.

SEva = A Live Demo of PII Firewall ​

Your question
  │
  ▼
① detectAllInjections()   ← SQL injection + prompt injection checked simultaneously
  │
  ▼
② fw.mask()               ← Any PII in your message (name, email, phone…) is auto-masked
  │
  ▼
③ Secure RAG search       ← Knowledge base (pre-anonymized via rag/ingest) is queried
  │
  ▼
④ Claude API              ← Response generated from masked text + RAG context
  │
  ▼
⑤ fw.restoreAll()         ← Mask tokens restored to original values

Displayed in the SEva panel

This is the same architecture as the Full Pipeline you'd build in your own production system using PII Firewall.

Secure RAG — How SEva's Knowledge Base Works ​

The knowledge base SEva uses to answer questions (PII Firewall docs, integration guides, FAQs) was pre-processed with rag/ingest before being stored in a cloud vector database for vector search.

Source documents (docs/)
  │
  ▼  rag/ingest
Anonymize + tokenize + chunk
  │
  ▼
Cloud vector DB (vector index)
  │
  ▼  at query time: search_embeddings()
Retrieve relevant chunks → pass to Claude

SEva is "an AI that uses PII Firewall's Secure RAG to answer questions about PII Firewall."
The product's philosophy is demonstrated by the product itself.

Real-Time Protection Stats in the SEva Panel ​

The counters shown in the SEva panel reflect actual numbers processed by the PII Firewall engine.

DisplayMeaning
🛡️ Masked this month: NPII detected and protected by fw.mask() in this session
⚡ Attacks blocked: NInjection attempts detected and blocked by detectAllInjections()

As developers use the Console and ask SEva questions, these counters increment in real time.
It's a live visualization of what PII Firewall is doing for you.

Privacy by Design — What SEva Knows ​

SEva is built on the same Privacy by Design principles as the rest of PII Firewall.

What SEva knows (behavioral metadata only) ​

What SEva never collects ​

InformationReason
Text you type in Console input fieldsYou may be testing with real PII
API response bodiesMay contain masked tokens or restored PII
Your actual API key valuesSecurity risk

🛡️ SEva does not read your input content
This is not a UI disclaimer — it is a design guarantee.
The same principle applies across PII Firewall: after installation, all processing runs locally. Only API call counts leave your environment.

What You Can Ask SEva ​

Integration & implementation ​

"What's the minimum code to use mask with the SDK?"
"How do I install the MCP Server in Cursor?"
"I want to implement the Full Pipeline: mask → LLM → restore in Node.js"
"What's the difference between detectAllInjections and detectInjection?"
"Why is the candidates array empty in /detect responses?"

Secure RAG ​

"What is Secure RAG?"
"How do I use rag/ingest vs rag/resolve?"
"Walk me through ingesting internal documents into Secure RAG"
"SRAG token restoration is failing — how do I troubleshoot?"

Shadow AI detection ​

"What is Shadow AI monitoring?"
"Show me an example of shadow-ai/check"
"How can I detect and log employees using ChatGPT?"

Plans & upgrades ​

"How many API calls does the Free plan include?"
"What changes when I upgrade to Starter?"
"Which plan is required to use Secure RAG?"

Error resolution ​

"I'm getting a CORS error. How do I fix it?"
"The OTP code isn't arriving in my inbox"
"I issued an API key but requests return 401"

FAQ ​

Q: Is it safe to share my API key with SEva? ​

Please don't. Avoid pasting real API keys into any AI service, including SEva.
Manage API keys through the API Keys panel.

Q: Can I paste real PII into SEva for testing? ​

We recommend against it. To test with PII-like data, use the TRY IT panel in the left sidebar — it routes requests through PII Firewall's full masking pipeline.

Q: What's outside SEva's scope? ​

SEva specializes in PII Firewall. General programming questions, legal advice, and medical advice are outside scope.

Q: What if my issue isn't resolved? ​

For critical issues (data loss, billing problems, security incidents), SEva escalates and notifies our team.
For general inquiries: support@piifirewall.com.
