We have Cisco ASA 5585-X with SSP-40 who CX module is defective and there’s no further upgrade for the same. We are planning to deploy Firepower 2130 below ASA as dedicated IPS box. (Architecture attached) We are very much concerned that what will be impact on performance and on user side whether they will face any issue in browsing as the throughput of Firepower is less in comparison to ASA. Seeking best response at the earliest please.
