The first blog I wrote about elastic cloud gateways prior to Black Hat 2019 referenced next-generation firewalls relative to the shift to application-centric, Layer 7 scanning, and the massive impact that had on the network security market. What I didn’t appreciate at the time is how similar the trajectory of the two spaces would be. In the 10 months since Black Hat, we’ve witnessed a massive amount of momentum in this area. In fact, recently completed ESG research on elastic cloud gateways found that 94% of organizations reported usage of, or some level of interest in, these types of solutions. With secure access services edge (SASE) having become common terminology within the network security space, I’m often asked what the difference is between ECG and SASE. The fact is, there are many more similarities than differences; however, the differences that do exist are important.
