Securing Customer Account Data in AI

Protect sensitive financial information across customer chatbots, employee copilots, and agent workflows without disrupting approved work.

Securing Customer Account Data in AI

Customer service assistants, loan officers, and financial agents routinely handle account numbers, Social Security numbers, balances, and payment information. That data can travel through prompts, generated responses, retrieved documents, and connected tools. PointGuard AI applies data protection policies at these interaction points, helping banks keep sensitive information within approved boundaries while employees and customers continue using AI.

Challenges

Financial data can leave approved systems through AI interactions that existing controls do not consistently inspect.

  • Employees paste borrower and account details into public AI services.
  • Chatbots can repeat confidential information in customer responses.
  • Agent tools can retrieve more financial data than a task requires.
  • Different models and applications apply inconsistent data protection rules.

Solution

PointGuard AI combines AI Data Protection, Runtime Guardrails, and MCP Security Gateway controls to enforce financial data policies across AI workflows.

1. Define sensitive data policies. Identify account details, payment information, personal identifiers, and bank-specific data that require protection. Set rules for permitted uses, destinations, and enforcement actions.

2. Inspect AI interactions. Scan prompts and responses for sensitive information, and inspect data moving through governed MCP tool calls. Apply policies before restricted content reaches a model, user, or connected service.

3. Redact or block exposure. Mask or redact sensitive fields where work can safely continue. Block interactions that exceed policy, including requests to send protected information to an unapproved destination.

4. Preserve enforcement evidence. Record detections, policy decisions, and actions for investigation and oversight. Give security teams a consistent view of financial data exposure across protected AI channels.

Risks Addressed

  • OWASP Top 10 for LLMs: LLM02 Sensitive Information Disclosure and LLM06 Excessive Agency, covering disclosure through model interactions and excessive access through connected tools.
  • OWASP Top 10 for Agentic Applications: ASI02 Tool Misuse and Exploitation and ASI03 Identity and Privilege Abuse, addressing misuse of tools and authority to retrieve or transmit account data.
  • NIST AI RMF: MAP identifies sensitive data flows; MEASURE evaluates exposure; MANAGE applies controls; GOVERN establishes ownership and policies.
