Intrusion Prevention System

Network Security
A Preemptive Threat Prevention in Real-time

Attackers often exploit system or application vulnerabilities to interrupt and gain control over applications or machines. The Zyxel Intrusion Prevention System (IPS) is also known as Intrusion Detection and Prevention (IDP), which is a network security and threat prevention technology that help businesses to establish timely security measures against known zero-day attacks. The IPS service fully guards your business network environment with anomaly traffic detection from a wide range of suspicious activities – like SQL injection, DoS and malicious backdoor applications.

Deeper, Wider, Stronger Intrusion Prevention

The Zyxel IPS service provides a high-performance deep packet inspection engine to examine all incoming and outgoing traffic – including SSL traffic for protocol deviations, content that signals an attack, or policy violations. The IPS operates in detection and prevention modes to defend operating systems and shield enterprise application vulnerabilities.

Virtual Patching

Shields vulnerabilities before exploit, eliminates the operational pains of emergency patching, frequent patch cycles, and costly system downtime

Cost-effective Solution

Provides network-wide protection for all users configured behind firewall with a single IPS subscription
