The Security Challenge in the Age of AI: Why Zero Trust Is More Relevant Than Ever
AI adoption requires greater control over data, identities, and permissions to ensure security and compliance.
Generative AI is transforming how organizations execute their internal processes. Through capabilities such as semantic search, copilots, AI agents, and task automation, it simplifies access to information and supports decision-making. As a result, activities that once required significant time and effort can now be completed more quickly and efficiently, boosting productivity.
However, this advancement requires organizations to revisit how they manage data and access controls. For years, companies focused on protecting applications, networks, and infrastructure. With generative AI, data protection becomes even more critical, as information stored, shared, and accessed by people, systems, AI agents, and applications now moves more dynamically across the corporate environment.
While generative AI can create content, it does not create access permissions. Its value lies in helping users locate, interpret, and leverage existing corporate data.
As a result, inappropriate permissions and excessive sharing become even more critical security concerns, creating new challenges for organizations. But what really changes in the risk landscape?
What Changes in the Risk Landscape?
Excessively Shared Data
Large volumes of information are stored and shared across platforms such as SharePoint, OneDrive, Teams, and other corporate repositories. While this enables collaboration, it can also increase access to content that should be restricted to specific users or teams.
Permissions Accumulated Over Time
Over time, users often accumulate unnecessary access rights due to role changes, completed projects, or employee departures.
As AI makes it easier to find and consolidate information, excessive permissions that previously went unnoticed become more visible and potentially easier to exploit.
Difficulty Controlling Sensitive Data
Organizations do not always have clear visibility into where their most sensitive information resides. Financial data, personal information, contracts, and intellectual property are often spread across different systems and repositories. Without proper visibility and controls, the risk increases that these data assets may be accessed by unauthorized individuals.
Given this scenario, it is becoming increasingly important to control who can access information, under what conditions, and for what purpose.
This is where the Zero Trust model becomes especially relevant, helping organizations protect their data in an environment that is increasingly connected and driven by AI.
Where Zero Trust Fits In
Zero Trust is based on the principle that no user, device, or application should be trusted by default. Instead of granting access automatically, every request must be validated based on the user's identity, the context of the request, and the associated level of risk.
This approach is built on three core principles: verify explicitly, use least-privilege access, and assume breach.
Assuming breach means operating under the premise that a security incident may occur at any time and implementing mechanisms to quickly detect suspicious activity and limit the impact of a potential compromise.
How to Prepare Your Organization for AI
Before implementing AI solutions, it is important to ensure that data, access controls, and permissions are properly organized and protected. Use the following checklist to prepare your organization for the secure adoption of AI:
Review access permissions;
Adopt least-privilege principles;
Map sensitive data;
Implement information classification;
Review sharing settings;
Define data protection controls (DLP and governance policies);
Assess Zero Trust maturity;
Create corporate AI usage policies;
Strengthen identity controls.
As AI becomes part of everyday business operations, governance becomes an essential requirement for its secure use. Organizations that adopt Zero Trust principles are better positioned to realize the benefits of AI while reducing risks and maintaining control over their information.
