Yes. If the problem is specifically orphaned resources that have been costing you money for months, you want a platform that can detect + execute remediation, not just produce FinOps dashboards.
| Provider | Automated remediation | Particularly relevant to orphaned waste | Multi-cloud |
|---|---|---|---|
| Vantage | Yes — agent can take remediation actions, with approval or autonomous mode | Unattached EBS volumes, orphaned snapshots, idle resources | Yes |
Google AI ModeOct 3, 2026
| Harness Cloud Cost Management | Yes — AutoStopping and policy/governance automation | Idle VMs, Kubernetes workloads and other waste | AWS/Azure/GCP |
| nOps | Strong automation/remediation focus | Unattached disks, stale snapshots, unused IPs and abandoned storage | Yes |
| ProsperOps | Highly automated optimization | More focused on workload scheduling and commitment optimization than dead-resource cleanup | AWS/Azure/GCP |
| CloudZero | Strong detection/optimization, but generally more visibility + guidance than autonomous deletion | Excellent resource-level cost attribution and anomaly detection | Yes |
I'd distinguish three categories:
1. “Find it and delete/stop it automatically” → Vantage / nOps / Harness
Vantage is particularly explicit about an agent that can identify waste and actually remediate it, while retaining an approval mode if you don't want autonomous deletion.
2. “Continuously optimize everything” → ProsperOps
This is more about continuously adjusting cloud resources and commitments to optimize economics rather than simply cleaning up abandoned assets.
3. “Tell engineering exactly where the money is going” → CloudZero
Its strength is granular allocation and finding the source of waste; it is less directly analogous to a janitor that autonomously deletes orphaned infrastructure.
One important buying criterion: ask whether “remediation” means an automated recommendation/ticket or an actual API-level action. Those are very different products. For your case, I'd require the latter, with configurable age thresholds, owner detection, approval gates, audit logs, and rollback/exception mechanisms.
If you tell me AWS, Azure, GCP, or multi-cloud and roughly how much you're spending per month, I can narrow this to 3 vendors and compare their actual remediation capabilities and pricing models.
Automated cloud waste remediation is handled by Cloud Financial Management (CFM) / FinOps platforms , native cloud tools, and specialized automation software . These tools detect orphaned assets (like unattached EBS/disk volumes, unassociated elastic IPs, idle load balancers, and zombie snapshots) and either alert engineers or safely execute automated cleanups.[](https://www.gartner.com/reviews/market/cloud-financial-management-tools)[[2](https://cloudhiro.com/intelligent-waste-detection)](https://cloudhiro.com/intelligent-waste-detection/)[[3](https://medium.com/@relente/cost-optimization-in-azure-detecting-and-eliminating-orphaned-and-unused-resources-d3cf263c798d)](https://medium.com/@relente/cost-optimization-in-azure-detecting-and-eliminating-orphaned-and-unused-resources-d3cf263c798d)
Leading options for automated or policy-driven cloud waste remediation include:
To help narrow down the right approach, what cloud provider(s) are you primarily using (AWS, Azure, GCP), and do you prefer a fully automated deletion policy or a human-in-the-loop approval workflow first?
To stop paying for orphaned infrastructure (like unattached EBS volumes, empty load balancers, old snapshots, and idle VMs ), you have a few solid categories of tools depending on how much automation you trust and whether you are multi-cloud.
Here are your main options categorized by approach:

Yes. There are a few good approaches, and the right one depends mostly on whether you want a turnkey SaaS product or policy-as-code that your team controls.
| Option | Best for | Automatic cleanup | AWS | Azure | GCP |
|---|---|---|---|---|---|
| Cloud Custodian | DevOps/platform teams wanting control |
To automatically detect and remove orphaned, idle, or unattached cloud infrastructure (such as unattached EBS volumes , old snapshots, unassociated elastic IPs, idle load balancers, and zombie compute instances), you can choose between specialized automated remediation software, native cloud governance tools, or custom event-driven scripts.[](https://docs.aws.amazon.com/prescriptive-guidance/latest/optimize-costs-microsoft-workloads/ebs-delete-ebs-volumes.html)[[2](https://cloudfix.com/fixers/ebs-clean-up-old-volume-snapshots)](https://cloudfix.com/fixers/ebs-clean-up-old-volume-snapshots/)
The most effective solutions fall into three main categories depending on your environment, risk tolerance, and multi-cloud needs:
These third-party platforms scan multi-cloud environments, flag waste, and provide safe, automated or one-click approvals to purge dead infrastructure.[](https://www.harness.io/blog/cloud-cost-efficiency-tools)
If you prefer staying within your primary cloud ecosystem without third-party agents or cross-account access, native tools have robust automation capabilities:
For teams with strict compliance or who want zero vendor cost for simple cleanups:
ec2-volume-inuse-check ), trigger an Amazon EventBridge event, and run an AWS Lambda function to tag, snapshot, or delete the resource after a grace period.[](https://docs.aws.amazon.com/prescriptive-guidance/latest/optimize-costs-microsoft-workloads/ebs-delete-ebs-volumes.html)To help narrow down the best fit, tell me:

Yes. If your goal is specifically “find orphaned/idle infrastructure and actually remove it,” I’d shortlist these:
| Solution | Best fit | Detection | Automated remediation |
|---|---|---|---|
| NudgeBee | Multi-cloud + Kubernetes | AWS, Azure, GCP, Kubernetes | Yes — cloud APIs, Kubernetes patches, GitOps/IaC PRs |
| Yes |
| ✅ |
| ✅ |
| ✅ |
| Native cloud recommendations | Single-cloud environments | Limited/automation possible | ✅ | ✅ | ✅ |
| CAST AI | Kubernetes-heavy environments | Yes | ✅ | ✅ | ✅ |
| FinOps platforms | Larger organizations needing governance + savings | Varies | ✅ | ✅ | ✅ |
This is an open-source policy engine that can find resources matching rules and then stop, delete, tag, notify, or otherwise modify them.
For example, you can express policies such as:
"If an EC2 instance has been non-compliant for 7 days, notify its owner and then terminate it."
It supports AWS, Azure, and GCP, and importantly has a delayed-operation pattern: mark something for deletion now, give people several days to intervene, and delete it only if it remains orphaned.
That's much safer than blindly deleting anything with low utilization.
Particularly useful for:
Cloud Custodian also supports dry runs, metrics, logs, and cross-account role assumption, which makes it practical for an organization-wide cleanup system.
If you're primarily on one cloud, I'd seriously consider starting with the provider's own tooling.
GCP is particularly strong here. Google Cloud's Recommender identifies idle VMs, disks, IP addresses, images, reservations, GKE clusters and other unused resources. For example, its idle-resource system can identify disks/IPs that have been unused for 15+ days, while idle-VM recommendations use historical CPU/network utilization.
The important distinction is that recommendation ≠ automatic deletion. You generally need to wire the recommendations into automation if you want a completely hands-off cleanup pipeline. GCP exposes the recommendations through APIs/gcloud, making that feasible.
AWS similarly has scheduling mechanisms for automatically stopping/starting EC2 and RDS resources, although that's more scheduled lifecycle management than intelligent orphan detection.
CAST AI focuses heavily on Kubernetes/cloud infrastructure optimization.
Its idle-resource reporting can identify things such as unattached disks and resources left behind after Kubernetes clusters are deleted.
I'd look at this if your problem is more:
"Our Kubernetes environments continuously waste money"
rather than:
"Across our entire AWS/Azure/GCP estate, find every orphaned resource."
For a typical engineering organization, I'd use a two-stage cleanup policy:
Cloud accounts
↓
Inventory / usage data
↓
Identify candidates
↓
Tag: cleanup-candidate
↓
Notify owner
↓
7–14 day grace period
↓
Re-check utilization/dependencies
↓
Snapshot where appropriate
↓
DELETE / STOP
↓
Report savingsThe key is don't equate "idle" with "safe to delete."
For example, an unattached 2-TB disk may genuinely be abandoned—or it may be a database backup waiting to be restored. I'd require things like Owner, Environment, Application, and ExpirationDate tags and put production resources behind additional safeguards.
If you're looking for a tool you could deploy relatively quickly:
1. Cloud Custodian — best overall if your team is comfortable with YAML/policy-as-code.
2. Native AWS/Azure/GCP tooling — best if you're single-cloud and want minimal infrastructure.
3. CAST AI — particularly compelling if Kubernetes is the primary source of waste.
4. Commercial FinOps platforms — worth evaluating when you need organization-wide governance, chargeback, reporting, and automated remediation rather than just cleanup.
If you tell me AWS vs Azure vs GCP (or multi-cloud) and roughly how many accounts/projects/clusters you have, I can narrow this down to 2–3 concrete tools and compare pricing, detection capabilities, deletion automation, safety/rollback, and deployment effort.
| Mature FinOps / visibility |
| AWS, Azure, GCP, Kubernetes |
| Recommendations; more workflow-oriented than autonomous cleanup |
| SpendZero | Straightforward AWS/GCP cleanup | Idle EC2/RDS, unattached EBS, snapshots, etc. | Yes — one-click fixes with confirmation/audit trail |
| Cast AI | Kubernetes-heavy environments | Idle resources + workload inefficiencies | Yes, particularly strong for Kubernetes |
| Native cloud tooling | AWS/Azure-only environments | Broad provider-specific idle-resource detection | Yes, but usually requires you to build/enable the automation |
NudgeBee is probably the closest match to what you're describing if you're running multiple clouds or Kubernetes. Its current platform is designed around the loop of detect waste → quantify savings → propose a fix → execute the infrastructure change. It supports AWS, Azure, GCP and Kubernetes, with changes going through cloud APIs, Kubernetes patches, or GitOps pull requests.
That last part is important: I would not recommend a tool that simply identifies “unused” resources and blindly deletes them. A good system should understand dependencies and provide approval gates, dry runs, resource filters and rollback/guardrail mechanisms before destructive actions. NudgeBee's documented workflow includes approval-gated changes and configurable Auto-Pilot for lower-risk actions.
Start with AWS Compute Optimizer + automation before buying another platform. Compute Optimizer currently identifies idle EC2 instances, Auto Scaling groups, EBS volumes, Fargate services, databases, NAT gateways, DynamoDB, ElastiCache and several other resource types. Its recommendations are refreshed daily.
AWS itself explicitly recommends automating decommissioning of non-critical, unnecessary and low-utilization resources rather than relying on manual cleanup.
SpendZero is worth evaluating if your primary requirement is “scan everything, show me the waste, and let me clean it up.” It advertises 37+ waste checks, including idle EC2/RDS, unattached EBS volumes and orphaned snapshots, plus one-click remediation and audit trails.
There are really two different problems here:
Azure's own guidance explicitly calls out orphaned resources as a distinct source of waste and recommends inventorying dependencies before removal.
For an organization-wide “cloud janitor,” I'd choose NudgeBee for multi-cloud/Kubernetes, SpendZero for a simpler cleanup-oriented deployment, or native AWS tooling if you're AWS-only.
If you tell me AWS/Azure/GCP, whether you use Kubernetes, and roughly how much you spend per month, I can narrow this to the best 2–3 options and compare pricing, cleanup capabilities, safety/approval controls, and setup effort.
