SSE Portion of SASE Twice the Size of SD-WAN

“We see SASE continuing to thrive independent of the ongoing macro-economic uncertainty as enterprises strategically invest for the new age of distributed applications and hybrid work that need a different approach to connectivity and security,” said Mauricio Sanchez, Research Director, Network Security, and SASE & SD-WAN at Dell’Oro Group. “We anticipate that security will increasingly be the driver and lead SASE’s SSE to exhibit over twice the growth of SASE’s SD-WAN,” added Sanchez.

Additional highlights from SASE and SD-WAN 5-Year Forecast Report:

Within SSE, Secure Web Gateway (SWG) and Cloud Access Security Broker (CASB) are expected to remain the most significant revenue components over the five-year forecast horizon, but Zero Trust Network Access (ZTNA) and Firewall-as-a-Service (FaaS) are estimated to flourish at a faster rate.
Unified SASE is expected to exceed disaggregated SASE by almost 6X.
Enterprise access router revenue is expected to decline at over 5 percent CAGR over the forecast horizon.
