Okay, I've been tasked with helping our sales director understand why we're looking at ZTNA vendors instead of just upgrading our current VPN. I've read the basics, but I want to make sure I get the practical, day-to-day differences for a team like ours.
Can someone help break down the core difference in a real-world scenario? For example:
* Our salespeople need access to the CRM (cloud), the internal sales forecasting tool (on-prem), and maybe some shared marketing drive.
* They're hopping between home WiFi, client offices, and coffee shops.
With our current VPN, they connect to the "office network" and then get to those resources. From what I gather, ZTNA doesn't give them that network layer at all. Is that right?
I'm especially curious about the user experience and security trade-offs:
* Does ZTNA mean they don't have a "connected" or "disconnected" state like a VPN tunnel?
* How does access to the on-prem tool work without the network tunnel? Is it more like a direct, secure application connection?
* From a risk perspective, if a sales laptop gets compromised, how does ZTNA limit the blast radius compared to a VPN that puts them on the internal network?
I've seen claims about performance being better because traffic doesn't hairpin through a central gateway. Is that generally true for globally distributed teams?
Finally, on the practical side, I'm trying to map out the comparison:
* **VPN:** We manage IP ranges, network rules, and sometimes deal with split-tunneling debates.
* **ZTNA:** Is it more about defining policies per application (or even per action within an app) based on user, device, and context?
How do vendors typically handle the shift? Is it an agent on the laptop, or can it be agentless for basic web apps? What's the common approach for a non-technical sales team?
