Do These 5 Things RIGHT NOW (30 Minutes)
⏰ If you've already used AI tools with confidential data, act immediately!
Every minute you delay increases your compliance risk and potential liability exposure.
1. Audit Your Current AI Usage (5 minutes)
Do this now:
- Open your ChatGPT, Claude, or other AI tool conversation history
- Search for any conversations containing customer names, employee data, financial information, or confidential business details
- Look for industry-specific sensitive data (patient info, client matters, student records, etc.)
- Screenshot or document what you find
- If you find sensitive data, immediately delete those conversations and note the date/time for your incident log
Reality: Even "anonymized" data can often be re-identified through cross-referencing. Australian privacy law considers this personal information.
2. Immediately Stop Entering Sensitive Data (2 minutes)
Send this message to your entire team RIGHT NOW:
"URGENT: Effective immediately, do NOT enter any confidential business information, customer data, employee records, or industry-specific sensitive information into ChatGPT, Claude, or any AI tool. This includes names, financial data, business strategies, or any details that could identify individuals or compromise our business. Use only hypothetical examples. This is to ensure compliance with privacy and confidentiality laws. More guidance coming soon."
3. Check What Data These Companies Keep (10 minutes)
For each AI tool you use, check their data retention policy:
✅ ChatGPT (OpenAI)
- • Go to Settings → Data Controls
- • Turn OFF "Improve the model for everyone"
- • Check chat history retention settings
- • Request data deletion if needed
✅ Claude (Anthropic)
- • Review their privacy policy on data use
- • Check if your conversations are used for training
- • Contact support to delete specific conversations
4. Document Any Privacy Incidents (5 minutes)
If you found sensitive data in step 1, create an incident report:
Incident Report Template:
- • Date/time of data entry
- • Which AI tool was used
- • Type of sensitive information shared
- • Number of individuals affected
- • Actions taken to mitigate (deletion, etc.)
- • Date of this discovery
Important: You may need to report this to relevant authorities (OAIC, industry regulators) if it meets the criteria for a notifiable data breach.
5. Contact Your Compliance Team (5 minutes)
Send this message to your compliance officer, or senior management:
"We need urgent guidance on AI tool usage and potential data exposure risks. Our staff may have inadvertently shared confidential business information or regulated data with AI services like ChatGPT/Claude. I have an incident report ready for review and have implemented immediate containment measures. Can we schedule a call today to discuss notification requirements, regulatory obligations, and next steps?"
How to Use AI Tools Safely in Business
The Golden Rule
If you wouldn't feel comfortable announcing the information at a public industry conference, don't put it in an AI tool.
Safe Prompting Techniques
Instead of this:
"John Smith from ABC Corp wants to renegotiate our $2M contract terms. His email shows they're struggling financially..."
Do this:
"A client wants to renegotiate contract terms, citing financial pressures. What are best practices for contract renegotiation?"
Safe Information to Share:
- General business scenarios and challenges
- Industry best practices and benchmarks
- Anonymous case studies and examples
- Technical specifications (non-proprietary)
- General legal and compliance questions
NEVER Share:
- Customer names, contacts, or identifying information
- Employee personal data or HR records
- Financial details, pricing, or contract terms
- Proprietary processes or trade secrets
- Strategic plans or competitive intelligence
- Any data subject to confidentiality agreements
Train Your Team (30 minutes)
Run this team meeting script:
- Explain the business and legal risks of AI tools
- Show examples of safe vs unsafe prompts
- Demonstrate how to delete conversation history
- Establish a "buddy check" system for AI use
- Create a reporting process for accidental data sharing
Tip: Make this training mandatory and document attendance for compliance purposes.
Contract Checklist
⚠️ Critical for Business AI Usage
If you're using AI tools for business purposes, these contract checks are MANDATORY to protect your organization.
1. Data Usage Rights in Your Contracts
Questions to ask your AI provider:
- "Can you use our data to train your models?"
- "Do you use our conversations to improve your service?"
- "Can we opt out of data usage for training?"
- "What happens to our data when we cancel our contract?"
Red Flag: If they can't clearly answer these questions or refuse to put it in writing, don't use their service for business data.
2. Data Storage and Processing Location
Essential questions:
- "Where is our data physically stored?" (Must comply with Australian data sovereignty requirements)
- "Which countries will process our data?"
- "Do you have adequacy decisions or appropriate safeguards for international transfers?"
- "Can we require data to stay in Australia?"
If required by law: International data transfers must comply with Australian Privacy Principle 8. Get this in writing.
3. Caching and Data Retention Policies
Critical contract clauses to demand:
- Maximum data retention periods (recommend 30-90 days maximum)
- Automatic data deletion timelines
- Your right to request immediate data deletion
- Confirmation that cached data is also deleted
- Audit rights to verify deletion
Sample Contract Language: "Provider shall not retain Customer data for longer than [30 days] and shall provide verifiable proof of deletion upon request within [24 hours]."
4. Liability and Insurance Coverage
Ensure your contract includes:
- AI provider liability for data breaches
- Indemnification for privacy law violations
- Minimum insurance coverage amounts
- Notification requirements for security incidents
- Your right to audit their security practices
Technical Security Implementation
1. Implement Access Controls
Set up these controls TODAY:
- Require unique accounts for each staff member (no shared logins)
- Enable two-factor authentication on all AI tool accounts
- Set up single sign-on (SSO) through your organization's identity provider
- Create role-based permissions (not everyone needs access)
- Regular access reviews (monthly for high-risk tools)
Pro Tip: Use your existing Microsoft 365 or Google Workspace SSO to control AI tool access centrally.
2. Network Security Measures
Technical steps to implement:
- Block AI tools on networks that handle sensitive data
- Create separate network segments for AI tool usage
- Monitor and log all AI tool traffic
- Implement data loss prevention (DLP) tools to scan for sensitive data
- Use web filtering to control which AI services can be accessed
3. Data Classification and Handling
Create clear data categories:
🚫 NEVER in AI
- • Personal identifiers
- • Confidential business info
- • Financial data
- • Trade secrets
⚠️ CAUTION
- • De-identified data
- • Aggregated statistics
- • Internal processes
- • Industry benchmarks
✅ SAFE for AI
- • General business info
- • Public research
- • Educational content
- • Hypothetical scenarios
Ongoing Monitoring & Compliance
Monthly Security Audits
Set up these recurring checks:
Monthly Audit Checklist:
- □ Review all AI tool conversation histories
- □ Check for any accidental sensitive data sharing
- □ Verify access controls are still in place

- Security audit findings and fixes
Retention: Keep these records for at least 7 years to meet regulatory requirements.
