Symantec Endpoint Protection's core protection against known and unknown threats uses a layered approach to defense. The comprehensive approach protects the network before, during, and after an attack. Symantec Endpoint Protection reduces your risk of exposure by providing tools to increase your security posture ahead of any attack.
To get complete protection for the computers in your network, enable all protections at all times.

Symantec Endpoint Protection uses the following holistic security approach to protect your environment across the entire attack chain, using the following stages: incursion, infection, infestation and exfiltration, and remediation and inoculation.
Phase 1: Incursion
During the incursion phase, hackers typically break into the organization's network using target attacks such as social engineering, zero-day vulnerabilities, SQL injection, targeted malware, or other methods.
Symantec Endpoint Protection protects against attacks before they enter your system using the following technologies:
Intrusion Prevention/Firewall (Network Threat Protection): Analyzes all incoming traffic and outgoing traffic and offers browser protection to block such threats before they can be executed on the computer. The rules-based firewall and browser protection protect against web-based attacks.
In targeted attacks, hackers typically break into the organization's network using social engineering, zero-day vulnerabilities, SQL injection, targeted malware, or other methods.
Symantec Endpoint Protection uses the following technologies to detect and prevent these attacks before they infect your system:
Memory Exploit Mitigation: Detects malware.
File reputation analysis (Insight): Based on the artificial intelligence that uses Symantec's global intelligence network. This advanced analysis examines billions of correlated linkages from users, websites, and files to identify and defend against rapidly-mutating malware. By analyzing key attributes (such as the origin point of a file download), Symantec can accurately identify whether a file is good or bad and assign a reputation score all before the file arrives on the client computer.
Advanced machine learning: Analyzes the trillions of examples of the good files and bad files that are contained in a global intelligence network. Advanced machine learning is a signatureless technology that can block new malware variants at the pre-execution.
High-speed emulation: Detects hidden malware using polymorphic custom packers. A scanner runs each file in milliseconds in a lightweight virtual machine that causes threats to reveal themselves, improving both the detection rates and performance.
Antivirus file protection (Virus and Spyware Protection): Uses signature-based antivirus and file heuristics to look for and eradicate malware on a system to protect against viruses, worms, Trojans, spyware, bots, adware, and rootkits.
Behavioral monitoring (SONAR): Leverages machine learning to provide zero-day protection, stopping new and unknown threats by monitoring nearly 1,400 file behaviors while they execute in real time to determine file risk.
Data exfiltration is the unauthorized transfer of data from a computer. Once the intruders control these target systems, they may steal intellectual property or other confidential data. Attackers use captured information for analysis and further exploitation or fraud.
Intrusion Prevention/Firewall: Block threats as they travel through the network.
Behavioral monitoring: Helps stop the spread of infection.
Phase 4: Remediation and Inoculation
Symantec Endpoint Protection includes a single console and agent that offers protection across operating systems, platforms, and businesses of any size.
Power Eraser: An aggressive tool, which can be triggered remotely, to address advanced persistent threats and remedy tenacious malware.
Host Integrity: Ensures that endpoints are protected and compliant by enforcing policies, detecting unauthorized changes, and conducting damage assessments. Host Integrity then isolates a managed system that does not meet your requirements.
System Lockdown: Allows the whitelisted applications (known to be good) to run, or blocks the blacklisted applications (known to be bad) from running. In either mode, System Lockdown uses checksum and file location parameters to verify whether an application is approved or unapproved. System Lockdown is useful for kiosks where you want to run a single application only.
Secure Web Gateway Integration: Uses programmable REST APIs to make integration possible with Secure Web Gateway, to help quickly stop the spread of infection at the client computer.
EDR Console Integration. Symantec Endpoint Protection is integrated with Symantec Endpoint Detection and Response and is designed to detect, respond, and block targeted attacks and advanced persistent threats faster by prioritizing attacks. EDR (Endpoint Detection and Response) capability is built into Symantec Endpoint Protection, which makes it unnecessary to deploy additional agents.
