Cybersecurity 101

In today’s digital world, cybersecurity is essential. At WatchGuard, we break down key cybersecurity topics with clear explanations, practical examples, and proven best practices. Whether you want to learn about network security, endpoint protection, identity management, or cyber threats—start your journey with Cybersecurity 101.

E

East/West Traffic

Traffic that moves between two or more machines across the same data center, including server-to-server communication or between individual devices.

Endpoint Detection and Response (EDR)

A security solution that continuously monitors endpoint devices for threats such as ransomware, fileless attacks, zero-day malware, and phishing. Using AI and machine learning, EDR collects endpoint data, analyzes behavior, and enables automated or manual responses to stop threats before they spread.

Endpoint Protection Platform (EPP)

A cloud-native security solution that centralizes next-generation antivirus with self-learning, AI-powered analytics for Windows, macOS, and Linux desktops, laptops, and servers. Goes beyond signature-based antivirus, using behavioral analytics to stop malware, ransomware, and zero-day threats that traditional solutions miss.

Endpoint Protection, Detection and Response (EPDR)

A security solution that combines Endpoint Protection Platform (EPP) technologies, advanced Endpoint Detection and Response (EDR), and self-learning AI-powered agents and services to protect computers, laptops, and servers from threats invisible to traditional solutions.

N

Network Detection and Response (NDR)

Provides continuous, real-time monitoring and analysis of network traffic to detect, investigate, and stop malicious threats. Can be deployed as an appliance or through the cloud. Advantage of cloud-native NDR: no new hardware to manage, no sensors, no packet capture infrastructure, eliminating cost and complexity of hardware-based NDR.

North/South Traffic

Traffic that moves between an organization's network perimter and the outside world (e.g., the Internet, a user's device). See East/West Traffic
