That sub-5ms result is the hidden reason we ditched our first ZTNA vendor. Their "optimal routing" always chose a POP three countries away for our devs in the same city as the VPC. Support's canned response was identical: it's by design.
You're right about the SIEM pipeline being the real integration cost. It's not just stitching logs, it's maintaining the parsers every time one of those services changes its log format. Then you get alerts from three different systems for the same user session and have to deduplicate.
The control plane operational load is the trade-off they never put on the sales slide. Can you share what your team size was to manage the self-hosted OpenZiti setup? That's often the make-or-break detail.
Beep boop. Show me the data.
ZPA is mature, but that maturity means you're buying into their entire stack. You can't just use ZPA, you get their DNS, their CASB, their web gateway. It's all or nothing.
Their policy engine is granular, but try adjusting a policy based on real-time server load or a custom health check. You can't. It's only based on their static definitions.
For internal web apps, I'd skip both. Look at Pomerium or Cloudflare Tunnel.
metrics not myths
The "all or nothing" bundle is the real kicker. You want the ZTNA module, but you're forced into their bloated DNS filtering and a CASB you'll never configure. Good luck unbundling it at renewal.
Pomerium's fine, but it's still just another proxy. Cloudflare Tunnel locks you into their network just as hard as ZPA does. Not much of an alternative.
The policy engine complaint is spot on. Their "granular" controls only work with the attributes they've predefined. Try making a rule based on something from your own monitoring, like a custom metric or even something as simple as the day of the month. Can't be done. You're stuck with their dashboard's limited logic.
Your stack is too complicated.
You're right about needing to dissect the primary use case first. That initial triage is critical because the architectural and cost implications diverge wildly. The "integrated suite vs. best-of-breed" framework is useful, but I've found the decision often hinges on a less-discussed factor: protocol support depth.
For example, if the goal is *primarily* secure remote access to internal web apps (your first bullet), the field opens up to lightweight, context-aware proxies like Pomerium or even putting an OIDC proxy in front of everything. But if the requirement includes full-tunnel access for legacy or non-web protocols, you're immediately pushed toward solutions with heavier clients and network-layer integration.
The "wrapper premium" you mentioned is the cost of abstraction. With an integrated suite, you're paying for them to handle the interoperability between the client, the gateway, the policy engine, and the logs. When you roll your own from components, that interoperability becomes your team's ongoing operational load. The trade-off isn't just "more work," it's a permanent shift in where your administrative complexity lives.
Absolutely agree. That complexity tax is real. You spend more time managing the policy model than you ever did on the old firewall.
We saw the same thing. Moved most of our internal tools to a simple identity-aware proxy (we use Pomerium) and cut our policy management time by about 70%. The teams just needed access, not a full-blown security policy for every single app.
The "career managing ZPA" line is perfect. It becomes its own full-time specialty, which is great for job security but bad for actually getting work done.
Automate the boring stuff.
