The sunsetting of Virtual Private Networks is underway.

VPNs are on a fast track to becoming obsolete, at least when it comes to defending enterprise networks. VPNs are being replaced by zero trust network access, or ZTNA.
VPNs encrypt data streams and protect endpoints from unauthorized access, essentially by requiring all network communications to flow over a secured pipe. VPNs verify once and that’s it. This was an effective approach when on-premises data centers predominated.
By contrast, ZTNA never trusts and always verifies. A user gets continually vetted, per device and per software application — and behaviors get continually analyzed to sniff out suspicious patterns.
Guest expert: Rajiv Pimplaskar, CEO, Dispersive
This new approach is required — now that software-defined resources scattered across hybrid and public clouds have come to rule the day.
I had the chance at Black Hat 2022 to visit with Rajiv Pimplaskar, CEO at Dispersive, an Alpharetta, GA-based supplier of advanced cloud obfuscation technology. We discussed how ZTNA has emerged as a key component of new network security frameworks, such as secure access service edge (SASE) and security service edge (SSE)
We also spoke about how Dispersive is leveraging spread spectrum technology, which has its roots in World War II submarine warfare, to more effectively secure modern business networks. For a full drill down on our forward-looking discussion, please give the accompanying podcast a listen.
Can the deployment of WWII battlefield technology turn the tide against hordes of threat actors? I’ll keep watch and keep reporting.
