Endpoint security plays a vital role in safeguarding devices such as laptops, desktops, and mobile systems that connect to a corporate network. One of the most commonly used tools for endpoint security is Symantec Endpoint Protection (SEP), known for its advanced threat prevention, firewall, and intrusion detection capabilities. It provides comprehensive defense against malware, ransomware, and zero-day attacks through continuous monitoring and real-time analytics.

1. Which Tool is Commonly Used For End Point
Security?​
​
​
​
In an era marked by digital transformation and remote work, endpoint security has
become the frontline defense for organizations seeking to protect sensitive data and
digital assets. As cyber threats evolve, securing endpoints such as laptops, desktops,
and mobile devices is essential to ensuring business continuity. In 2025, endpoint
security tools will have advanced to include artificial intelligence (AI), machine learning
(ML), and behavior-based detection, offering comprehensive protection from
ransomware, phishing, and zero-day attacks.
Understanding Endpoint Security
Endpoint security refers to the process of protecting endpoints—devices connected to a
network—from malicious activities or cyber threats. Unlike traditional antivirus software
that relies heavily on signature-based detection, modern endpoint protection platforms
(EPP) and endpoint detection and response (EDR) solutions use AI, cloud analytics, and
real-time monitoring to identify suspicious behaviors. These tools provide an integrated
defense mechanism that can automatically detect, isolate, and remediate threats
across endpoints.

2. Importance of Endpoint Security
The rise in hybrid and remote work environments has expanded the attack surface for
businesses. According to multiple security analyses, most cyberattacks now originate
from compromised endpoints. Attackers exploit weak points such as outdated
software, unsecured remote connections, or phishing attempts targeting employees.
Effective endpoint security tools safeguard against these issues by offering real-time
monitoring, advanced threat intelligence, incident response, and vulnerability
management capabilities.​
The Most Commonly Used Endpoint Security Tools
1. CrowdStrike Falcon
CrowdStrike Falcon is one of the most widely recognized endpoint protection platforms,
renowned for its cloud-native architecture and AI-driven analytics. It provides real-time
monitoring and detection across a wide range of endpoints without compromising
system performance. Falcon Insight XDR extends this protection by integrating with
cloud environments and offering proactive threat hunting, forensic analysis, and
automated remediation. Its lightweight agent ensures minimal resource usage, making
it ideal for both small teams and large enterprises.​
2. Microsoft Defender for Endpoint
As part of the Microsoft 365 security ecosystem, Microsoft Defender for Endpoint
seamlessly integrates with Windows, macOS, Linux, and mobile platforms. It offers a
unified view of threat exposure through features like attack surface reduction,
vulnerability management, and AI-powered automated investigation and response. Its
cloud-native capabilities and integration with Azure Active Directory help organizations
centralize their endpoint management while mitigating emerging threats.​
3. SentinelOne Singularity
SentinelOne’s Singularity platform is built on autonomous AI that offers behavioral
analysis, automated response, and rollback features for ransomware mitigation. It
provides complete visibility of attacks on endpoints, including lateral movements and
root cause analysis. Security teams benefit from real-time analytics and the ability to
contain threats instantly without manual intervention. SentinelOne has become a leader
in endpoint security for organizations demanding speed, automation, and precision.​
4. Symantec (Broadcom) Endpoint Protection

3. Symantec Endpoint Protection, now part of Broadcom, remains a strong contender for
comprehensive enterprise-level protection. Its integrated data loss prevention (DLP),
AI-based scanning, and intrusion prevention systems provide layered protection across
devices. The platform includes advanced firewall and application control functions,
making it a solid solution for enterprises managing hundreds or thousands of endpoints
globally.​
5. Trellix (McAfee) Endpoint Security Suite
The Trellix Endpoint Security platform (formerly McAfee) combines signature-based and
AI-driven malware detection with global threat intelligence. It offers integrated firewall,
web control, and central management through its ePolicy Orchestrator (ePO). Trellix is
particularly effective for organizations seeking to balance legacy compliance
requirements with modern, adaptive security mechanisms.​
6. Check Point Harmony Endpoint
Check Point’s Harmony Endpoint integrates EPP, EDR, and XDR functionalities in a single
client solution. It focuses on preventing ransomware, phishing, and data loss threats
while supporting remote work environments. With centralized management and
automated threat containment, Harmony Endpoint is well-suited for mid-to-large
enterprises managing distributed workforces.​
7. Fortinet FortiClient and FortiEDR
Fortinet offers a dual-solution approach: FortiClient provides secure connectivity
through VPN and endpoint compliance checks, while FortiEDR offers advanced
detection and automated incident response. The FortiEDR platform uses behavioral
analytics to detect deviations in system behavior and includes post-infection
remediation to reverse malicious activity. This makes it an excellent choice for
businesses integrating endpoint protection within a broader network security
ecosystem.​
8. Sophos Intercept X
Sophos Intercept X combines next-generation antivirus with deep learning neural
network detection to identify advanced threats proactively. It includes ransomware
rollback, exploit prevention, and EDR capabilities. The Sophos Central dashboard allows
unified management and forensic visibility across diverse endpoint environments. Small
and medium-sized businesses (SMBs) appreciate its ease of deployment paired with
enterprise-grade protection.​

4. Key Features That Make These Tools Stand Out
Modern endpoint security tools share several critical features that elevate their value:
●​ AI and Machine Learning: Most tools utilize predictive algorithms to recognize
unusual behaviors, detecting threats before they activate.
●​ Automation and Remediation: Tools like Microsoft Defender and SentinelOne
automatically isolate infected endpoints and roll back malicious changes.
●​ Centralized Management: Platforms such as Trellix and Sophos allow
administrators to manage thousands of devices from one interface.
●​ Cross-platform Coverage: Support for Windows, macOS, Linux, Android, and iOS
ensures consistent protection across hybrid environments.
●​ Integration: Integration with SIEM (Security Information and Event Management)
and SOAR (Security Orchestration Automation and Response) systems enhances
efficiency and visibility.
Choosing the Right Endpoint Security Tool
Selecting an endpoint security tool depends on your organization’s structure, operating
systems, and security maturity level. Enterprises might prefer advanced EDR/XDR
solutions like SentinelOne, CrowdStrike Falcon, or Microsoft Defender for their
scalability and integration capabilities. SMBs, on the other hand, may opt for Sophos
Intercept X or Fortinet FortiClient for their simplicity and cost efficiency.
Key evaluation criteria include:
●​ Technical integrations with existing systems
●​ Deployment flexibility (cloud vs. on-premises)
●​ Automation features and reporting
●​ Customer support and vendor reputation
●​ Cost-effectiveness relative to scale
Conclusion
As cyber threats intensify, endpoint security remains an organization’s first and last line
of defense. The leading tools of 2025—CrowdStrike, Microsoft Defender, SentinelOne,
Symantec, Trellix, and others—demonstrate how AI-driven advancements and
automation can transform threat management. By selecting a solution aligned with their
operational needs, organizations can safeguard endpoints, streamline security
operations, and strengthen resilience against tomorrow’s cyber risks
