A Network Intrusion Prevention System (NIPS) is capable of monitoring and validating encrypted
data if it is integrated with technologies that allow it to decrypt the traffic.
Typically, network IPS can be set up with SSL/TLS decryption capabilities to inspect encrypted data as
it traverses the network. This allows the IPS to analyze the content of encrypted packets and apply
security policies accordingly.
Monitoring encrypted traffic is critical in detecting hidden malware, unauthorized data exfiltration,
and other security threats concealed within SSL/TLS encrypted sessions.
