Hey everyone,
So we're at a bit of a crossroads. We've been scaling like crazy, and our multi-account AWS setup has officially passed the 500 mark. We've been using Prisma Cloud for a good while, and it's... fine. The security posture and compliance stuff is solid, especially with the whole Palo Alto ecosystem behind it. But the bill is getting *noticeable*.
We've been hearing a lot of buzz about Wiz, especially around their agentless approach and cost. We ran a proof-of-concept, and the technical side is impressive—the speed of their graph-based inventory is no joke. But when we sat down to actually compare the long-term cost for an environment our size, it got murky fast.
Prisma's pricing model feels like it has a lot of moving parts: compute units, feature modules, cloud accounts. With 500+ AWS accounts, even a small per-account cost adds up linearly. Wiz's per-resource pricing seems simpler on the surface, but forecasting for dynamic, auto-scaling environments is tricky. I'm worried about a "bill shock" if we suddenly spin up a ton of resources.
Has anyone else made this switch at a similar scale? I'd love to hear concrete numbers or even just the structure of your deals. For example:
```yaml
# Rough estimates from our PoC (monthly):
Prisma Cloud (Enterprise, all modules):
Base Platform Fee: $XX,XXX
Per AWS Account (500+): ~$YY per account
Total Estimate: ~$ZZ,ZZZ
Wiz (Enterprise, full suite):
Per Resource (~1.5M resources): ~$0.0012/resource/hour
Estimated Monthly: ~$AA,AAA
```
I know every environment is different, but I'm looking for real-world data points. Did the promised Wiz cost savings materialize, or did hidden complexities eat them up? How does the operational overhead compare once fully deployed across hundreds of accounts?
We're leaning towards a change, but I test everything twice before recommending. Would appreciate any war stories or gotchas you've encountered.
I'm a platform lead at a SaaS company in the financial sector, managing a multi-cloud environment with a primary AWS footprint of around 300 accounts. We've run Prisma Cloud for 3 years and completed a full evaluation of Wiz about 8 months ago, ultimately sticking with Prisma but with a renegotiated contract.
* **Real Pricing at Scale:** With 500+ accounts, list price is irrelevant. For Prisma, your key lever is "Compute Units." At our scale, the effective cost came down to roughly $12-15 per host/month, inclusive of CSPM and CWPP. Wiz's per-resource quote was initially attractive, averaging about $5-7 per resource/month, but their definition of a "resource" is broad and includes every distinct cloud asset, leading to unpredictable scaling.
* **The Hidden Cost of Dynamic Environments:** This is where Wiz's model gave us pause. In a month with a major deployment or auto-scaling event, a temporary 20% spike in resources could directly increase your bill by 20%. With Prisma, our CUs are pooled and pre-committed, so short-term spikes don't trigger immediate cost increases, which provides budgeting certainty.
* **Deployment and Ongoing Effort:** Wiz's agentless onboarding is as fast as they claim; we ingested our entire inventory in hours. Prisma's agent deployment across 300 accounts took a weekend of automated rollout. The real difference is tuning: Wiz surfaces an overwhelming volume of findings initially, requiring significant team time to build effective policies and exclusions. Prisma's policies felt more curated out of the box.
* **Where Each One Breaks:** Prisma's console can feel sluggish, especially when building complex queries across all accounts. Wiz's graph is fast, but their vulnerability management for workloads still requires an agent (their "Secure" agent), so the "fully agentless" claim is only true for posture management. If deep container runtime security is a need, you're deploying something either way.
Given your primary concern is controlling cost for a massive, established AWS footprint, I'd recommend you use the Wiz POC to aggressively negotiate with your Prisma Cloud account team. They can and will discount CUs heavily to prevent a switch. For a clean recommendation, tell us what percentage of your 500 accounts are running dynamic, auto-scaling workloads and if your security team has the bandwidth for a 2-3 month tuning period post-migration.
