Does your company control extensions and downloads or is it exposed to Shadow IT?

O Shadow IT invisível vai além do conceito tradicional de uso de ferramentas não autorizadas pela TI.

While classic Shadow IT is associated with clearly identifiable external systems and applications, the invisible is born within the workflow itself, especially in the browser.

The main difference is in capillarity and difficulty of detection. know if they are fragmented, distributed actions and often considered "harmless" by users.

As a result, this type of risk does not appear in classic IT controls, which are typically focused on endpoints, networks, and e-mail, but do not have granular visibility into actual user behavior in the environment where the work actually happens.

Are extensions and downloads a Shadow IT risk?

Extensions and downloads have become the new security blind spot because they shift risk away from traditional controls and directly into user behavior.

Today, the browser is no longer just a tool for accessing the internet and has become the main work environment, where the following take place:

• Critical decisions every day;

• Access to systems;

• Content consumption;

• Data exchange;

• Installation of additional features.

  
  

It is in this context that risk materializes in a dynamic and distributed way, making it difficult for security teams to see and control.

Browser extensions exemplify this problem well. They are easily installed by the users themselves, often without any technical validation or alignment with corporate policies.

Even when there are formal guidelines, practical application is limited, as these extensions operate within a highly flexible and decentralized environment.

In addition, many have broad permissions to access pages, browsing data, and credentials, creating a significant attack surface that often goes unnoticed by traditional governance mechanisms.

Downloads, on the other hand, represent a silent vector of risk because they happen continuously and, most of the time, outside of any in-depth inspection.

As a result, seemingly legitimate files can carry malicious code, scripts, or vulnerabilities that only manifest themselves after execution. Since these downloads are part of the operational routine, they are rarely questioned by users.

In this way, the users themselves end up increasing the risk and without visibility into the context of who downloaded it, where it came from, with what intention the organization loses the ability to prevent incidents before they happen.

What are the risks generated by extensions and downloads?

Extensions and downloads significantly expand the attack surface by introducing risks that often operate under IT's radar.

Data leakage is one of the main impacts, as many extensions request broad permissions such as access to pages, forms, and credentials, and can capture and transfer sensitive information without clear visibility.

In addition, access to malicious websites remains a relevant vector, especially when redirects, scripts, or compromised content are triggered directly in the browser, without going through traditional layers of protection.

Another critical point is the execution of unreliable code, often embedded in downloaded files or even in functionalities of seemingly legitimate extensions. These codes can exploit vulnerabilities, install backdoors, or silently compromise the environment.

As a consequence, there is a progressive loss of visibility on the part of IT, which fails to keep track of what really happens. Without context on actions such as installs, downloads, and accesses, responsiveness becomes reactive and often late.

How to transform behavior into a security layer?

Transforming behavior into a layer of security means leaving a model based only on technical control and starting to act directly in the way people interact with the digital environment.

Instead of relying solely on lockdowns and static rules, security evolves into a contextual model, where every action becomes an opportunity to prevent risks and guide safer decisions as they happen.

But how is this possible? It is essential that organizations create mechanisms capable of executing these actions. Here's how to implement these actions in your organization.

Continuous monitoring of navigation

Continuous navigation monitoring allows you to  follow, in a structured way, how users interact with the digital environment over time.

Unlike one-off or incident-based approaches, this model creates a persistent view of behavior, identifying patterns, deviations, and potential risks before they become real problems.

This includes everything from accessing untrusted websites to installing extensions or performing downloads outside the expected standard. With this level of monitoring, security is no longer reactive and starts to act predictively.

The organization is able to correlate events, understand context, and prioritize actions based on real risk, not just isolated alerts.

This reduces operational noise and increases the efficiency of teams, while strengthening protection without generating unnecessary friction for the user.

Education at the moment of risk

Education at the moment of risk is one of the most effective mechanisms for behavior change, as it acts exactly when the decision is being made.

Instead of generic, practice-disconnected training, the user receives contextual guidance, directly related to the action they are about to perform, such as accessing a suspicious website, downloading a file, or installing an extension.

This type of approach significantly increases learning retention and the likelihood of safer decisions in the future.

By turning every interaction into a learning point, the organization builds a culture of continuous safety, where employees are no longer just a vector of risk and start acting as an active line of defense.

Real-time visibility

Real-time visibility is essential for the organization to understand what is really happening in the digital environment, without relying on downstream analysis or outdated reports.

With immediate access to user actions such as browsing, downloads, and use of extensions, it is possible to identify risky behaviors as they arise and act quickly to mitigate impacts.

In addition, this visibility allows for more assertive decision-making, based on concrete and up-to-date data.

Security, IT, and management teams now operate with a greater level of control and clarity, managing to align strategy, governance, and user experience in a single flow. The result is more efficient security that is aligned with reality.

Why don't traditional tools see this problem?

Traditional security  tools were designed for a scenario where the perimeter was more defined, focused on e-mails and corporate networks. In this context, a large part of the investments and controls focused on protection against:

• Phishing;

• Malware;

• Attachments;

• Known threats on the device.

  
  

The problem is that the work environment has evolved, and today the browser has become the main point of interaction with systems, data, and services. Even so, many solutions continue to operate with an excessive focus on endpoints.

This is very harmful, as it ends up missing a gap precisely where user behavior most impacts risk.

In addition, there is a structural limitation in the reactive approach of these tools.

They rely on signatures, indicators of compromise, or events already identified to take action, which reduces the ability to prevent emerging risks.

Without granular visibility into what happens inside the browser, such as extension installation, browsing patterns, and real-time decisions, the organization loses context and timing.

The result is security that reacts late, with little precision, while risk is already in motion in the daily lives of employees.

What role does PeopleX play in combating Shadow IT?

PeopleX acts directly at the point where the risk actually happens, the browser. Instead of relying solely on external layers of protection, the platform integrates with the employee's workflow.

With this, it monitors navigation, identifies risky behaviors and acts preventively.

This allows you to block or alert on unsafe access, suspicious downloads, and the use of untrusted extensions at the time these actions occur, reducing your organization's exposure to threats that would normally go unnoticed.

In addition to technical prevention, PeopleX strengthens security by embedding ongoing communication and education within the digital routine. Content, alerts and guidance are delivered contextually, in the browser itself.

With this, the organization not only reduces immediate risks, but also evolves employee behavior over time, creating a more mature, active safety culture aligned with day-to-day reality.
