Let's get this straight: you're looking at Prisma Access for securing video conferencing traffic, and your first concern is latency. Good. That's the right concern. Most people just shove everything into their SASE and wonder why their all-hands looks like a potato.
Prisma Access is a solid platform, but its backbone isn't always the optimal path for real-time UDP-heavy traffic like Zoom, Teams, or Webex. The "low-latency" promise often gets diluted by hairpinning through the nearest PoP only to be routed across their network, which might not align with your conferencing provider's optimal ingress points. You'll see jitter. You'll see packet loss. Your users will complain, and your help desk tickets will spike right when you're trying to prove the ROI on this expensive SASE migration.
You need a competitor that treats real-time media as a first-class citizen, not just another TCP flow to inspect and proxy. Here's what I'd evaluate, focusing on architectural specifics:
* **Zscaler Zero Trust Exchange**: Their biggest advantage is the sheer density of their POPs. For end-users, connecting to a physically closer gateway reduces the initial hop latency. More critically, they have dedicated "Video Conferencing Subnet" configurations and can partner with providers like Microsoft for optimized Teams routing. The catch? You must meticulously define your traffic steering rules. A blanket "send all video traffic direct" policy defeats the security purpose, but sending it all through the cloud can add hops.
* **Netskope Private Access**: This is interesting because of their direct-to-app approach. Instead of backhauling all traffic to a security stack, they try to establish a lightweight, secure connection directly to the application (e.g., the Microsoft 365 front door). For a known SaaS app like Teams, this can mean fewer network transitions. However, their real-time traffic performance is highly dependent on your location relative to their edge nodes and the app's own infrastructure.
* **Consider a Hybrid Model with Cato Networks**: Cato's pitch is a fully meshed, global private backbone. The potential benefit for video is consistency. Once on their backbone, the route between your user in Lisbon and your resource in Chicago is managed by them, potentially avoiding the public internet jitter. The question is whether their backbone's latency between any two points is better than a (well-configured) direct internet path for that specific video service.
**Critical Configuration Pitfall to Avoid:**
Don't just rely on the vendor's "optimize for video" checkbox. You must segment this traffic in your policy. Here's a simplistic example of the *thinking* behind the rule, not a production-ready snippet:
```yaml
# This isn't any vendor's actual syntax, it's the logic you need to implement.
Policy Rule:
Name: "Optimize-VC-Traffic"
Source: Any User
Destination:
- IP ranges for Zoom (e.g., 13.107.xx.xx/24)
- IP ranges for Microsoft Teams (13.107.64.0/18, etc.)
- URLs: *.zoom.us, *.teams.microsoft.com
Application: Identified as "Zoom" or "Microsoft Teams"
Action: Bypass Deep Packet Inspection (DPI)
Route: Use most direct path to provider egress; disable TCP optimization.
Security: Apply only identity-based access control & basic threat prevention.
```
You're trading some depth of security inspection for latency. That's the negotiation. The "best" competitor is the one that gives you the granular controls to make that trade-off effectively, provides the most stable and short paths for your specific user geography, and doesn't make you deploy ten different client configurations to achieve it.
Now, who's actually tried implementing these granular policies on the platforms I mentioned? I want to hear about the actual latency metrics before/after, not the sales deck. What were the unforeseen snags?
