Why it matters
Prompt injection in tool-enabled enterprise agents can turn trusted data sources into attack vectors for data exfiltration, which defenders must address as an architectural trust-boundary problem.
A Sogeti Labs explainer argues that prompt injection — especially indirect prompt injection through documents, emails, and other consumed data — becomes a trust-boundary problem once agentic AI systems gain tools, memory, APIs, and permission to act. The article uses an example of a vendor-invoice agent tricked by hidden text into emailing payment instructions to an attacker, and contends enterprises need identity, policy, and architecture controls rather than treating it as a prompt-engineering issue.
