** From ChatGPT to TDX: How a 50-Person Law Firm Switched in One Afternoon

Quick Answer: A Paris-based law firm was sanctioned (privately) for uploading client NDAs to ChatGPT. They switched to VoltageGPU’s Confidential Agent Platform the same afternoon. Total migration time: 3 hours. Cost: $349/month for the entire firm. Even their IT team couldn’t access the documents.

TL;DR:

• Problem: ChatGPT processes data on shared, unencrypted GPUs. A single hypervisor breach exposes everything.
• Solution: Intel TDX enclaves on H200 GPUs ($3.60/hr). Hardware encryption, zero data retention, GDPR Art. 25 native.
• Result: 50 users migrated in 3 hours. No code changes — just swapped the OpenAI base URL.

Why This Firm Panicked

Three red flags triggered the switch:

1. Undisclosed Sanction: The Paris Bar privately fined a peer firm for ChatGPT use (confirmed by two partners).
2. Shadow IT Audit: 68% of employees admitted pasting client data into ChatGPT (internal survey).
3. Harvey AI’s $1,200/Seat Pricing: Prohibitively expensive for small firms.

The 3-Hour Migration

1. Step 1: Replace the API Endpoint

   # BEFORE (ChatGPT - risky)
   from openai import OpenAI
   client = OpenAI(api_key="sk-chatgpt-key")  

   # AFTER (TDX - encrypted)
   client = OpenAI(
       base_url="https://api.voltagegpu.com/v1/confidential",
       api_key="vgpu_YOUR_KEY"  # SHIELD-LEGAL gives 24h free Pro access
   )

No other code changes needed.

1. Step 2: Test with Real NDAs

   • Accuracy: 91% match vs manual review (tested on 20 NDAs).
   • Speed: 55 sec/NDA vs ChatGPT’s 48 sec (TDX overhead: 5.2%).
   • Cost: ~$0.50/analysis vs $600+/lawyer hour.

2. Step 3: Deploy Firm-Wide

   • Shared one .env file with the new base URL.
   • Trained staff in a 30-minute lunch session.

What They Gained

Limitations They Accepted

• 3-7% Latency Hit: TDX encryption adds ~200ms/request.
• No PDF OCR: Text-only for now (OCR coming Q4).
• Cold Starts: 30-60s if unused >15 minutes (Starter plan).

Try It Yourself

1. Live Demo: Upload your NDA — no signup.
2. 24h Pro Trial: Use code SHIELD-LEGAL at app.voltagegpu.com/register.

*Don’t take my word for it. The firm’s IT lead said:

“We thought encryption would break everything. It just worked.”*
