Compare
SaaS FinOps platforms are good. They all share one architecture.
This isn't a takedown. The mature platforms are genuinely strong: broad multi-cloud coverage, unit economics, polished tooling. But every major one processes your cost and resource data in its own cloud, not yours. StratoLens takes the opposite trade: it deploys inside your Azure tenant, so the data never leaves. If that's the sentence your security team has been waiting for, keep reading.
Side by side
Capability by capability
An honest look. Where the SaaS platforms win a row, we say so, and some rows they win outright. "Partial" means it depends on the vendor, or the capability exists with real limits.
| Capability | SaaS FinOps platforms | StratoLens |
|---|---|---|
| Runs inside your own tenant | No The four major platforms we reviewed (CloudHealth, Cloudability, CloudZero, Vantage) are vendor-hosted: cost and resource data flows out of your tenant into their cloud for processing, and none documents a self-hosted deployment of the platform. | Yes Deploys as a Managed Application inside your own Azure tenant. Cost and inventory data never leaves your environment: zero data exfiltration, by architecture. |
| Data residency you can show an auditor | Partial Cloudability has announced an Australia-hosted deployment for APAC customers, and its parent Apptio lists US and EU data centers. None of the four publishes selectable residency options; CloudZero offers hosting details on request. | Yes Residency is whatever your tenant's residency is. The processing location is your own subscription, in the Azure region you chose. |
| Read-only, least-privilege access | Yes To their credit, all four connect with read-only access, typically a Reader-scoped service principal plus a billing-scope role. The access model is sound; the difference is where the data goes afterward. | Yes The same model: Reader-scoped access, no write permissions. The scan results simply stay in your tenant instead of leaving it. |
| Multi-cloud coverage | Yes Genuinely broad: AWS, Azure, GCP, and Kubernetes, and often SaaS and AI spend (Datadog, Snowflake, OpenAI) in the same view. If your estate really spans clouds, this is real value. | No Azure only, deliberately. The trade is depth over breadth: Entra group resolution, Azure commitment mechanics, and policy drift instead of provider count. |
| Unit economics and mature cost tooling | Yes CloudZero models cost per customer or per feature and enables anomaly detection by default; Vantage offers virtual tagging, a public API, and a Terraform provider. This is a mature product category. | Partial Cost anomalies correlated with the changes behind them, commitment coverage, and waste detection for Azure. No unit-economics modeling: if cost-per-customer is your core need, the SaaS platforms are ahead. |
| Azure depth beyond cost | Partial Varies. CloudZero, Vantage, and Cloudability are cost platforms: configuration is read to attach dollars to resources. CloudHealth goes further with a cross-cloud policy engine, though its security governance module is AWS-only and in beta. None documents an Azure-native change, identity, and topology record. | Yes RBAC analysis with usage data, change tracking with snapshot diffs, network topology, and governance findings, built Azure-first. |
| Pricing decoupled from your cloud bill | Partial Varies by vendor. Enterprise platforms are commonly quote-only with spend-scaled contracts (Cloudability's published tiers start around $30,000/yr at $1M managed spend). Vantage publishes flat self-serve plans, gated by tracked-spend ceilings. | Yes Flat tiers by environment size with every feature included. The bill does not grow because your cloud spend did, and it never takes a percentage. |
| Nothing of yours to run | Yes It is their service to run: usually nothing on your side beyond the service principal, though Cloudability's recommended Azure path has you host the cost-export storage account it reads from. | Partial It runs in your tenant, so it is your infrastructure: a 15-minute Marketplace deploy, updates delivered through the Managed Application, and a footprint that typically runs under $1/day. |
Runs inside your own tenant
SaaS FinOps platforms
The four major platforms we reviewed (CloudHealth, Cloudability, CloudZero, Vantage) are vendor-hosted: cost and resource data flows out of your tenant into their cloud for processing, and none documents a self-hosted deployment of the platform.
StratoLens
Deploys as a Managed Application inside your own Azure tenant. Cost and inventory data never leaves your environment: zero data exfiltration, by architecture.
Data residency you can show an auditor
SaaS FinOps platforms
Cloudability has announced an Australia-hosted deployment for APAC customers, and its parent Apptio lists US and EU data centers. None of the four publishes selectable residency options; CloudZero offers hosting details on request.
StratoLens
Residency is whatever your tenant's residency is. The processing location is your own subscription, in the Azure region you chose.
Read-only, least-privilege access

Multi-cloud coverage
SaaS FinOps platforms
Genuinely broad: AWS, Azure, GCP, and Kubernetes, and often SaaS and AI spend (Datadog, Snowflake, OpenAI) in the same view. If your estate really spans clouds, this is real value.
StratoLens
Azure only, deliberately. The trade is depth over breadth: Entra group resolution, Azure commitment mechanics, and policy drift instead of provider count.
Unit economics and mature cost tooling

Who this is for
Where the difference shows up
If you're in a regulated industry...
You may have already ruled the SaaS category out, not because the tools are weak but because infrastructure data leaving the tenant is a non-starter. StratoLens is the answer that lets you say yes: the same cost and visibility findings, produced and stored inside the boundary your regulator already approved.
StratoLens for regulated industriesIf you're running FinOps on Azure...
At more than one major platform, the vendor's own docs show Azure trailing AWS: automation that supports only AWS "at this time," resource coverage a fraction of what AWS gets. StratoLens is Azure-first: cost anomalies correlated with the change that caused them, commitment coverage, and orphaned-resource detection across every subscription.
StratoLens for FinOpsIf you're facing a vendor-risk review...
Adding a SaaS processor for infrastructure data means questionnaires, DPAs, and subprocessor lists, and three of the four major platforms do not publish where your data would be hosted. A Managed Application in your own tenant changes the scope of that review entirely.
StratoLens for complianceCredit where due
Where SaaS FinOps platforms fit
If your estate genuinely spans AWS, Azure, and GCP, your security team is comfortable with a third-party processor, and cost-per-customer analytics is the core need, the mature SaaS platforms serve that well. That's their home ground, and pretending otherwise would make everything else on this page less believable.
But Azure-centric teams cross the line sooner than expected. The vendor-risk questionnaire asks where infrastructure data is processed and the honest answer is "the vendor's cloud, region not published." An auditor asks for the processing location of cost data. A data-residency clause rules out a new subprocessor. Or the renewal quote scales with exactly the spend you were brought in to reduce. That's the gap StratoLens closes: the cost findings, the visibility, and the audit evidence inside your own tenant, at a flat price on your existing Azure invoice, without a byte leaving your environment.
