An essential component of enterprise cybersecurity is the endpoint protection platform, and this importance stems from various reasons. Primarily, in today’s business landscape, a company’s most valuable asset is its data, and the loss of such data or access to it could jeopardize the entire business, potentially leading to insolvency. Additionally, businesses grapple not only with an increasing number of endpoints but also with a diversity of endpoint types. These challenges not only make enterprise endpoint security inherently more complex but are further exacerbated by remote work and BYOD policies, rendering traditional perimeter security inadequate and introducing vulnerabilities.
The complexity of the threat landscape adds another layer of difficulty. Hackers continually devise new methods to gain access, steal information, or manipulate employees into divulging sensitive data. When considering the opportunity cost of reallocating resources from business objectives to address threats, the reputational consequences of a large-scale breach, and the actual financial repercussions of compliance violations, it becomes evident why endpoint protection platforms are now considered indispensable for securing modern enterprises.
How endpoint protection works
Endpoint security involves protecting the data and workflows associated with individual devices connected to a network. Endpoint protection platforms (EPP) operate by scrutinizing files upon entry into the network. Modern EPPs leverage cloud capabilities to maintain an expansive threat information database, eliminating the need for local storage on endpoints and the associated upkeep. Accessing this information in the cloud enhances speed and scalability.
The EPP offers system administrators a centralized console, typically installed on a network gateway or server, enabling cybersecurity professionals to remotely manage security for each device. Client software is then assigned to each endpoint, delivered either as a remotely managed Software as a Service (SaaS) or installed directly on the device. After setup, the client software can push updates, authenticate log-in attempts, and enforce corporate policies from a single location. EPPs secure endpoints through application control, blocking unsafe or unauthorized applications, and encryption to prevent data loss.
Once configured, the EPP swiftly detects malware and other threats, with some solutions incorporating an Endpoint Detection and Response (EDR) component. EDR capabilities enable the detection of advanced threats like polymorphic attacks, fileless malware, and zero-day attacks through continuous monitoring, providing enhanced visibility and a range of response options.
EPP solutions are available in on-premises or cloud-based models. While cloud-based products offer scalability and seamless integration with existing architectures, specific regulatory or compliance requirements may necessitate on-premises security.
What’s considered an endpoint?
If a device is linked to a network, it is classified as an endpoint. The proliferation of BYOD (bring your own device) and IoT (Internet of Things) has led to a substantial increase in the number of individual devices connected to an organization’s network, reaching into the tens or hundreds of thousands.
Endpoints encompass a variety of devices, including the more commonly recognized:
- Tablets
- Mobile devices
- Smartwatches
- Printers
- Servers
- ATM machines
- Medical devices
As entry points for threats and malware, endpoints, particularly mobile and remote devices, are attractive targets for adversaries. Mobile endpoint devices now extend beyond traditional Android devices and iPhones to include the latest wearable watches, smart devices, voice-controlled digital assistants, and other IoT-enabled devices. Network-connected sensors are embedded in diverse settings such as cars, airplanes, hospitals, and even on oil rig drills. As the types of endpoints continue to diversify and grow, the corresponding security solutions must adapt to provide effective protection.
Endpoint security components
Typically, the essential components included in endpoint security software are as follows:
- Machine-learning classification for the detection of zero-day threats in near real time.
- Advanced antimalware and antivirus protection aimed at safeguarding, detecting, and rectifying malware across various endpoint devices and operating systems.
- Proactive web security measures to ensure secure browsing on the internet.
- Data classification and data loss prevention mechanisms to avert data loss and unauthorized data exfiltration.

Types of endpoint security
Attackers stay informed about security trends to develop more covert attacks, making traditional antivirus tools obsolete. Endpoint security integrates the preventive measures of an EPP solution with the detection and investigative features of an EDR.
Endpoint Protection Platform (EPP)
An EPP solution serves as a proactive tool, offering point-in-time protection by inspecting and scanning files upon entering a network. The common form of endpoint protection is a conventional antivirus solution, which includes antimalware capabilities primarily designed for safeguarding against signature-based attacks. Upon a file entering the network, the antivirus solution scans it to determine if its signature matches any known malicious threats in a threat intelligence database.
Endpoint Detection and Remediation (EDR)
An EDR solution surpasses simple point-in-time detection mechanisms by continuously monitoring all files and applications entering a device. This constant monitoring enables EDR solutions to provide more comprehensive visibility and analysis for threat investigations. EDR solutions can detect threats beyond traditional signature-based attacks, including fileless malware, ransomware, polymorphic attacks, and more.
Extended Detection and Response (XDR)
While EDR enhances malware detection compared to antivirus capabilities, XDR expands on EDR’s scope to encompass a broader array of deployed security solutions. XDR possesses a more extensive capability than EDR, utilizing cutting-edge technologies to enhance visibility. It collects and correlates threat information, employing analytics and automation to detect present and future cyberattacks effectively.
