Practices for Integrating AI Agents into Enterprise Systems 【Trust Boundary Split】 💡 Catchy Message "Running your customer-facing and employee-facing agents on the same stack? That's a ticking time bomb for data leakage." Employee agents and customer agents have fundamentally different trust levels, data boundaries, and failure costs. Treating them as one design is how internal data leaks through customer-facing channels. 🔥 Problems Solved - Internal data leakage through customer-facing agent paths (the most critical risk) - Adversarial input exploitation (jailbreaks, indirect prompt injection) causing runaway behavior - Accidentally applying employee-tier "relaxed assumptions" to customer-facing agents - Irreversible brand damage and legal liability from customer-facing failures 🏗️ The Pattern Separate employee-facing and customer-facing agents into two distinct trust planes -- physically or logically isolated. Employee agents authenticate via corporate IdP (Okta/Entra ID) with broad internal data access. Customer agents live in a DMZ-equivalent isolated environment, accessing only explicitly published read models (projections of approved data). All customer-facing output must pass through DLP (Data Loss Prevention) inspection. Guardrails for the customer plane are significantly stricter: jailbreak detection, topic restrictions, tone control, and denial policies. You can share orchestration infrastructure and model gateways, but data access paths must always be separated. ✅ When to Adopt - Use when: Both customers and employees use agents. B2C/B2B companies where customer touchpoints and internal operations share infrastructure. - Skip when: Purely internal-only use cases (separation adds cost without benefit). ⚠️ Pitfalls - Sharing orchestration infrastructure and mistakenly assuming data paths are also safe. Infrastructure sharing and data path separation must coexist. - Deferring customer-facing guardrail design to "phase 2." Jailbreak detection, topic restrictions, and denial policies must be part of the initial architecture. - Neglecting audit log design for customer identifiers and PII retention policies, leading to compliance violations. 🛠️ Implementation Approach - Set up network segmentation to isolate the customer plane. Deploy customer-facing agents in a DMZ-equivalent environment using VPC/subnet separation, blocking direct access to internal networks. - Build CQRS read models (projections of approved public data) for the customer plane. Replace direct internal DB access with curated views of explicitly publishable data only. - Deploy a DLP (Data Loss Prevention) inspection pipeline on the customer-facing output path. Route all output through this pipeline to detect and block internal data leakage. - Apply strict guardrail policies to the customer plane: jailbreak detection, topic restrictions, tone control, and denial policies -- significantly stricter than the employee plane. - Separate authentication infrastructure. Use corporate IdP (Okta/Entra ID) with SSO for employees and customer IdP (Auth0/CIAM) for customers, keeping auth paths fully independent. #AIAgents# #EnterpriseArchitecture#

Let's consult the historical record to see what the Aztec society was up to when the Spanish conquered it. First, from Cortes: “They have a most horrid and abominable custom which truly ought to be punished and which until now we have seen in no other part, and this is that, whenever they wish to ask something of the idols, in order that their plea may find more acceptance, they take many girls and boys and even adults, and in the presence of the idols they open their chests while they are still alive and take out their hearts and entrails and burn them before the idols, offering the smoke as sacrifice. Some of us have seen this, and they say it is the most terrible and frightful thing they have ever witnessed… not one year passes in which they do not kill and sacrifice some fifty persons in each temple; and this is done and held as customary… not one year has passed… in which three or four thousand souls have not been sacrificed in this manner.” And now Bernal Diaz del Castillo: “The dismal drum of Huichilobos sounded again, accompanied by conches, horns and trumpet-like instruments. It was a terrifying sound, and when we looked at the tall cue [temple] from which it came we saw our comrades who had been captured in Cortes’ defeat being dragged up the steps to be sacrificed. When they had hauled them up to a small platform in front of the shrine where they kept their accursed idols we saw them put plumes on the heads of many of them; and they made them dance with a sort of fan in front of Huichilobos. Then after they had danced the papas [priests] laid them down on their backs on some narrow stones of sacrifice and, cutting open their chests, drew out their palpitating hearts which they offered to the idols before them.” ... “Every day we saw sacrificed before us three, four or five Indians whose hearts were offered to the idols and their blood plastered on the walls, and their feet, arms and legs of the victims were cut off and eaten… Every wall of this chapel and the whole floor, had become almost black with human blood, and… the stench was worse than in a Spanish slaughter-house.” ... “When we arrived at the great market place, called Tlaltelolco, we were astounded at the number of people and the quantity of merchandise that it contained… Let us begin with the dealers in gold, silver, and precious stones, feathers, mantles, and embroidered goods. Then there were other wares consisting of Indian slaves both men and women; and I say that they bring as many of them to that great market for sale as the Portuguese bring negroes from Guinea…. They brought some of them tied to long poles by means of collars around their necks so they would not escape, and others left loose.” ~~ This is what the Spanish conquered in the name of Christendom - a Stone-Age society consumed with ritualistic human sacrifice, cannibalism and slavery.
