The primary function of intrusion prevention systems (IPS) is to monitor network traffic for suspicious activity and to actively intervene to prevent cyber threats. By analyzing data packets and applying predefined security rules, IPS can detect and block potential threats in real-time, protecting organizational systems from breaches and attacks. They serve as an essential layer of defense alongside firewalls, offering automated responses to identified vulnerabilities and anomalies. Organizations leverage IPS to uphold the integrity of their networks and safeguard sensitive information, especially against invasive threats such as malware or unauthorized access attempts.
