Enterprise technology rarely changes through a single decision. 

Rather , technology usually becomes part of the business gradually. One department solves an immediate problem, another adopts a different tool, and eventually those individual decisions become part of the organization’s operating model. 

Artificial intelligence has followed that same pattern, only much faster. For example, marketing teams found new ways to create content. Developers began using AI coding assistants to write and troubleshoot software. Business users discovered they could summarize reports, analyze spreadsheets, or automate repetitive work in minutes rather than hours. 

Each decision made sense on its own, but collectively, they changed the enterprise. We see this in many of our client conversations. Nobody scheduled a kickoff meeting to “become an AI-driven organization.” It happened anyway, one department at a time, and most security teams are still working out exactly how much of it is already running. 

The result is an AI environment that developed faster than most organizations could govern it. Organizations often talk about AI as though it arrived through a single initiative. In practice, it has spread through hundreds of individual business decisions made across different teams, often without a centralized deployment plan. 

Traditional governance assumes organizations understand what technologies they’re deploying before those technologies become part of everyday operations. AI often reverses that sequence. By the time leadership begins discussing enterprise AI strategy, employees may already be relying on multiple AI services, development teams may already be integrating large language models into applications, and another group may already be experimenting with autonomous agents. 

AI Didn’t Arrive Through One Enterprise Initiative 

During a recent WEI podcast conversation, Anthony Seto, AI Security GTM at Palo Alto Networks, put the problem into practical terms: organizations are not dealing with one form of AI. Each type creates a different security responsibility. 

Organizations don’t usually move through AI one phase at a time. More often, they discover they’re already operating in multiple stages simultaneously. One team is consuming public AI services. Another is building AI-enabled applications. Somewhere else, an operations group is evaluating autonomous agents to automate repetitive work. Each initiative may have started independently, but together they create an enterprise AI environment that requires more than a single security strategy. 

Consider how this already looks inside a typical organization: 

• A salesperson asks a public AI service to summarize meeting notes before visiting a customer. 

• A development team builds an internal AI application to help employees locate technical documentation. 

• An operations team tests an AI agent capable of retrieving information from multiple systems and completing routine administrative tasks. 

Most business leaders would reasonably describe all three scenarios above as “using AI.” 

From a security perspective, however, they represent three very different environments. 

Anthony describes this progression as AI You Use, AI You Build, and AI That Acts. The framework is straightforward, but it reflects something many organizations have already experienced. 

Each stage creates a different security responsibility. Treating all three as one initiative can leave organizations applying the wrong controls to the wrong problem. In practice, that’s usually the first thing WEI has to sort out with a client: which of the three environments a given AI initiative falls into. 

Staying Left of Bang: WEI’s Take on AI Security 

Long before AI entered the picture, WEI built its cybersecurity practice around a military term: left of bang. Picture an incident, the “bang,” in the middle of a timeline. Everything to the left is the discovery, testing, and preparation that can prevent it. Everything to the right of the bang is the response. AI does not get an exception. 

Applied to AI, that means knowing what is running, understanding what it can reach, and establishing controls before an incident forces the conversation. 

Different AI Requires Different Thinking 

The public AI services many of us utilize (Claude, ChatGPT, Gemini, etc.) primarily raise questions about the information employees share through prompts and uploads. When an organization builds its own AI, the responsibility expands. Security teams need confidence in where the models originated, whether the training data can be trusted, how the models were tested, and how they behave in production. 

The good news is that organizations do not have to start from scratch. Secure software development, application testing, and continuous monitoring still apply. AI simply introduces new artifacts, attack surfaces, and operating risks. 

Agentic AI raises the stakes further. It can retrieve information, access enterprise applications, execute workflows, and complete tasks on behalf of users. That’s what makes it valuable. It’s also what changes the nature of security. Organizations are no longer governing information alone. They’re governing authority. 

This is often where WEI’s assessments spend the most time, because an agent’s access and permissions may not be fully documented in one place.

When AI Moves From Responding to Acting 

Recent events illustrate why that distinction matters. 

The EchoLeak vulnerability and the widely reported Replit incident in 2025, in which an AI agent deleted a production database despite explicit instructions not to make changes, are becoming familiar reference points for security teams. The incidents were different, but they exposed the same problem: AI systems can receive access and permissions that traditional security programs were not designed to oversee.  

That’s an important shift because organizations have traditionally focused on controlling access for people and applications. Agentic AI introduces another participant into that model. Security teams must understand what these systems can access, which actions they can perform, and whether those permissions remain appropriate.

Visibility Shapes Every Decision That Follows 

Technology discussions often begin with governance frameworks, acceptable use policies, or security platforms. Those conversations all have value, but they assume organizations understand the environment they’re trying to govern. 

Security teams may have approved enterprise platforms while remaining unaware of browser extensions, coding assistants, internally developed models, autonomous agents, or Model Context Protocol connections already operating elsewhere in the organization. 

Governance can only go so far when organizations lack complete visibility into the environment those policies are meant to cover. 

That is why WEI begins its AI security engagements with discovery: understanding the environment before recommending a product. Organizations cannot determine which controls are appropriate, or how much authority an AI system should receive, until they know what is operating, what it can access, and what actions it can take. 

Security Should Grow Alongside the Technology 

What makes AI different is the speed at which those individual decisions have accumulated. AI is already part of everyday business operations, often in ways that aren’t immediately visible across the enterprise. 

Moving first will not matter if an organization cannot see or govern the AI already operating across its business. The better path is to understand what is in use, secure each stage according to the risk it creates, and expand AI’s authority deliberately. That’s the work WEI does with clients across all three stages, from AI readiness assessments through ongoing governance. 

Next Steps: WEI’s AI security assessments provide the insight needed to secure the AI you use, the AI you build, and the AI that acts on your behalf, without slowing down innovation. Whether you need to uncover shadow AI, secure a model before production, or govern what an autonomous agent can access, our team is here to help.
