Introduction
In 2023, the average global cost of a data breach reached US$4.45 million, representing a 15% increase in three years , according to IBM's annual report . This value reflects not only ransom payments but also the costs associated with data recovery, operational disruptions, regulatory sanctions, and damage to corporate reputation—perhaps the most difficult to repair.
The case of MOVEit , a file transfer platform used by thousands of companies worldwide, illustrates this scenario well. Also in 2023, a security flaw exposed data from more than 62 million people and compromised more than 2,000 organizations , and an image crisis. And all this stemmed from a neglected entry point : a vulnerable
endpoint These numbers reveal an urgent reality: endpoints have become the new risk perimeter for companies . Laptops , smartphones , servers, and any device connected to the corporate network are now preferred targets for cybercriminals. Protecting these entry points requires much more than just antivirus software. It demands continuous monitoring, incident response, vulnerability management, and robust access policies.
endpoint security solutions help companies address these threats with strategy, technology, and a forward-thinking approach .

What is endpoint ?
In the past, protecting a company's devices mostly meant installing a good antivirus and hoping for the best. But the scenario has changed, and quickly. Today, with the rise of remote work, the increasing use of the cloud, and the diversity of connected devices, risks have multiplied in areas that, until recently, were not at the center of security attention: endpoints .
But what exactly are endpoints ? They are all the physical devices that connect to a corporate network and interact with the organization's systems and data. We are talking about laptops , smartphones , tablets , desktops , point-of-sale terminals, servers, and even IoT equipment (such as connected security cameras or industrial sensors). Each of them acts as an entry point , and therefore as a potential vulnerability.
Thus, endpoint is the answer to this new reality. It is a set of solutions and practices aimed at protecting each individual device against unauthorized access, malware , data hijacking, and other threats that exploit the decentralization of the digital environment.
But what differentiates this approach from what we traditionally know as antivirus software? Let's find out.
Difference between antivirus vs. endpoint
The difference lies not only in the technology, but also in the vision. While antivirus software acts reactively , focused on identifying and eliminating known malicious files, endpoint security adopts a proactive and integrated approach , geared towards prevention, monitoring, and response.
endpoint security solution is capable of identifying suspicious behavior even before a threat is effectively executed. It can isolate a compromised device, block communications with suspicious addresses, and trigger automatic alerts for security teams—all in real time, based on continuous intelligence .
Furthermore, endpoint considers the device's context : its access level, location, compliance with internal policies, and even integration with other security layers, such as firewalls , SIEMs, and identity solutions. In other words, it's an architectural vision, not just a point-in-time defense .
Therefore, what we have is not a replacement for antivirus software, but an evolution . And given the level of sophistication of current threats, this evolution has gone from optional to mandatory.
Before we delve deeper into the practical workings of these solutions, it's worth understanding why endpoints have gained such prominence in companies' risk assessments. And this has everything to do with how and where these devices are being used today.
Why endpoints become the weakest link in corporate security?
No company grows today without endpoints . They enable operations, mobility, customer service, and productivity. But as they gain prominence, they also become one of the biggest weaknesses in security architecture .
For years, corporate protection was structured around a perimeter: the company's internal network, surrounded by firewalls , access controls, and centralized systems. But this perimeter no longer exists as it once did. With the popularization of the cloud, the use of personal devices to access corporate systems, and remote and hybrid work, data now circulates through less predictable—and much more vulnerable—paths.
Laptops connected to public networks, cell phones with multiple applications installed, servers operating outside data centers . Each of these scenarios represents an entry point that challenges classic control models. And in many cases, even the security team doesn't have complete visibility over all these devices.
Furthermore, in decentralized environments , such as those that adopt BYOD ( Bring Your Own Device ) policies, the challenge multiplies. How can consistent security policies be applied when devices are not standardized, updated, or managed in the same way?
This is why endpoints have become the most vulnerable link in corporate security. Not because of an isolated technical weakness, but because they have begun to operate outside the coverage area of traditional protections , in constantly changing environments and with direct access to sensitive data.
endpoint security acts precisely in this context, bringing visibility, control, and real-time response to each connected device.
Endpoint security : how it works in practice
In theory, protecting endpoints is simple: ensure that each device is monitored, updated, and has controlled access. In practice, this requires coordination between various technologies, automated responses, and intelligent policies that adapt to user behavior and environmental risk.
endpoint security acts as a living, responsive system —observing, analyzing, and acting based on context, behavior, and real-time data.
In practice, this action is based on three central pillars :
1) Continuous monitoring of behavior and traffic : visibility is the starting point. Monitoring endpoints in real time means understanding how each device behaves; what processes it executes; which systems it accesses; what type of data it handles and how often. When cross-referenced, these signals reveal deviations that may indicate the beginning of an attack. This intelligence allows for the identification of threats even before they are triggered;
2) Detection and response with EDR : EDR ( Endpoint Detection and Response ) adds a strategic layer to protection. It not only detects malicious patterns but also executes immediate containment actions . It can isolate a device, interrupt suspicious connections, and initiate an automated investigation, reducing the time between detection and response. This transforms the endpoint from a vulnerable point into active defense agent .
3) patch management and granular access control: known flaws continue to be exploited by attackers, even when patches are available . These patches are updates released by manufacturers to close critical vulnerabilities . Automating the application of these patches ensures that devices are patched quickly, without relying on manual cycles . In parallel, granular access control establishes who can access what, based on variables such as identity, device, location, and network type. This prevents users or applications from performing sensitive actions without proper authorization.
By combining endpoint security solutions act comprehensively and continuously , reducing the attack surface and strengthening the company's digital resilience.
But what kind of threats can they actually neutralize? That's what we explore in the next section. Keep reading!
endpoint solutions
Devices connected to the corporate environment are frequent targets of attacks that take advantage of the flexibility and mobility endpoint security works to contain threats that originate, manifest, or spread directly from these devices.
Below are some of the most common threats that can be detected and neutralized endpoint protection strategy :
- Malware installed from malicious files : the user opens a seemingly harmless attachment, runs a compromised installer, or accesses a malicious link malware installs itself locally, silently. Endpoint monitor system activity in real time and stop the process as soon as they detect patterns outside of expected behavior—before the code spreads or acts on sensitive data.
- Ransomware with file hijacking attempts : upon compromising a device, ransomware begins encrypting locally stored files and, in many cases, also accesses shared directories on the network. Endpoint recognizes this atypical behavior (such as rapid modifications to a large volume of files) and automatically blocks its execution.
- Exploitation of known, unpatched vulnerabilities : Even with updates available, many companies are slow to apply security patches endpoints . Modern solutions automate the application of these patches, closing loopholes as soon as they are documented and made available by manufacturers.
- Fileless attacks executed directly in device memory : In this type of attack, no infected files are written to disk. Instead, malicious code is injected into the system's RAM, often using legitimate tools such as PowerShell or scripts Endpoint security can detect these executions through continuous analysis of processes and commands, even without the presence of physical files.
- Lateral movement from a compromised endpoint : An attacker who gains access to a device attempts to use it as a bridge to reach other areas of the network, escalating privileges or accessing critical systems. Endpoint prevents this type of advance by segmenting traffic, limiting permissions, and monitoring attempts to escalate access directly on the device.
These examples reveal a central point: the most impactful attacks often begin discreetly and silently . That's why acting at the endpoint , intelligently and quickly, is no longer a reactive measure. It's the most direct way to contain threats before they scale.
In the next section, we advance our journey to learn about the technologies that make this action possible. Furthermore, we will also see how they combine to form a robust protection architecture connected to the reality of businesses.
More effective protection technologies and approaches
Effectively protecting endpoints demands a coordinated architecture capable of combining prevention, rapid response, and contextual analysis . It's not just about blocking a threat, but about understanding its behavior, anticipating risks, and acting quickly.
Below, we explore the technologies that underpin this integrated approach.
EPP, EDR and XDR: complementary layers
In a landscape of increasingly sophisticated threats, protecting endpoints requires a layered approach , where each technology plays a specific but complementary role.
The Endpoint Protection Platform ( EPP ) is the first line of defense . It works by blocking known threats based on signatures, filtering malicious files, controlling the use of removable media, and reinforcing protection with local firewalls It is effective in preventing traditional attacks, but it cannot handle threats that use evasive tactics and unprecedented behavior on its own.
This is where Endpoint Detection and Response ( EDR ) comes in. This layer continuously monitors endpoints , analyzing device behavior in real time. Thus, it is able to identify anomalous activities, such as the execution of suspicious code, lateral movement, fileless , and persistence attempts. In other words, EDR complements EPP by detecting what escapes signatures, offering automated response and detailed telemetry for investigations.
Extended Detection and Response ( XDR ) represents an evolution of protection . By orchestrating EDR data with telemetry from other sources (such as network, email , servers, and identities), it expands visibility and connects the dots to identify more complex campaigns. This reduces detection and response time , as well as decreasing the time the threat remains on the network.
With these three layers integrated , companies move from simply reacting to incidents to anticipating them intelligently and quickly , consolidating a much more contextual and effective defense.
Integration with SIEM and AI: scalable analysis and context-driven response
endpoint protection depends not only on what happens on each individual device, but also on the ability to understand the digital environment as a whole. This is where SIEM ( Security Information and Event Management ) comes in, a platform that centralizes and correlates security events from different sources : network logs endpoint , and more.
On its own, SIEM acts as a structured repository of security data. But when combined UEBA ( User and Entity Behavior Analytics ) and SOAR ( Security Orchestration, Automation and Response solutions , it gains predictive intelligence . This integration allows for the correlation of seemingly isolated events, the identification of unusual patterns based on behavior, and the automation of responses driven by real risk.
machine learning models , SIEM can anticipate suspicious behavior and execute corrective actions quickly . Thus, it reduces response time, minimizing false positives and increasing the accuracy of decisions.
This orchestration is what transforms scattered data into coordinated actions , connecting context, urgency, and impact in a much more strategic response flow.
Cloud-based security
The decentralization of work environments has imposed a new challenge to endpoint : maintaining control even when devices operate outside the corporate network. In hybrid and remote scenarios, relying on local or on-premise solutions compromises security effectiveness.
In this context, cloud-based security gains prominence by enabling :
- Centralized, real-time visibility of all devices, regardless of location or network used;
- Uniform application of security policies , with continuous monitoring;
- Automatic updates , based on the latest threats and behavioral patterns;
- The ability to scale and adapt as the digital environment evolves.
Furthermore, architectures such as SASE ( Secure Access Service Edge ) and ZTNA ( Zero Trust Network Access ) are also becoming established as pillars for intelligently endpoints . While SASE combines network and security functions in a single cloud-based layer, ZTNA reinforces the principle of minimal access. In this way, no user or device is trusted by default, and all access is verified based on identity, context, and security posture.
More than adopting isolated technologies, protecting endpoints today requires an orchestrated and adaptable approach . This involves understanding how these solutions integrate to ensure real-time visibility, response, and governance.

endpoint security
Endpoint security is one of the most critical aspects of modern cybersecurity; however, it still raises questions, both technical and strategic. Below, we've compiled direct answers to the most common questions on the topic, whether you're a technology expert or a decision-maker seeking more clarity.
What does endpoint ?
Endpoint security is the set of technologies and practices aimed at protecting devices connected to the corporate network (such as laptops , smartphones , servers, and IoT equipment). It works by preventing unauthorized access, blocking malware , monitoring suspicious behavior, and responding to incidents in real time. Its goal is to prevent these devices from becoming vulnerable points that compromise the entire operation.
What is the function of endpoints in a corporate network?
Endpoints are the access points between users and corporate systems. They execute tasks, access data, interact with applications, and often operate outside the traditional network perimeter, especially in hybrid and remote environments. Therefore, in addition to enabling operations, they can also serve as entry points for attacks. This makes their protection a strategic priority for information security.
What is the difference between antivirus and endpoint ?
Antivirus software is a layer of protection focused on known threats, based on signatures. Endpoint encompass technologies such as EPP, EDR, and XDR, which act proactively, monitoring behaviors, detecting advanced attacks (such as fileless attacks and APTs), and automating real-time responses. In short, antivirus software reacts; endpoint security anticipates, responds, and integrates with the corporate security ecosystem.
endpoint security affect device performance?
endpoint security solutions operate in a lightweight and efficient manner, often processing complex analytics in the cloud, which reduces the impact on devices. Furthermore, it's possible to configure protection levels according to the user's profile, ensuring a balance between performance and security.
