On average, enterprises waste $1 in every $4 spent on cloud — on idle VMs, orphaned storage, and unoptimised commitments. CoreStack continuously monitors your entire cloud estate and helps eliminate cloud wastage before it compounds.
Tell us where you're spending — we’ll show you exactly where your cloud spend is being wasted. No commitment, no fluff.
Your cloud bill grows every month — but the waste hiding inside it is nearly impossible to see without the right lens. By the time your team catches it manually, the damage is done.
The average enterprise with $250K/month in cloud spend is silently wasting $52,500 – $87,500 every month. That's over $1M a year — undetected, unreported, unrecovered.
These are not edge cases — they exist in every multi-cloud environment. CoreStack detects all six, continuously.
VMs, containers, and compute instances left running with zero utilisation — often from dev/test environments that were never shut down.
Up to 12% of total spendWorkloads running on compute that is 3–5x larger than required. Right-sizing alone recovers significant monthly spend across Azure, AWS, and GCP.
Up to 15% of total spendPersistent disks, blob containers, and database snapshots attached to nothing — quietly accumulating charges month after month.
Up to 8% of total spendReservations bought but underutilised, or on-demand spend in categories that should have been reserved 12–18 months ago.
Up to 10% of total spendUntagged, ungoverned workloads deployed outside central oversight — no allocation, no accountability, no visibility.
Untracked by definitionEgress fees and cross-region data movement charges that multiply invisibly across a multi-cloud estate without architectural governance.
Up to 6% of total spendNo lengthy onboarding. No lengthy contracts. Just a clear picture of where your cloud budget is going and how to get it back.
Grant CoreStack read-only access to your AWS, Azure, or GCP environment. No write permissions, no infrastructure changes. Secure by design.
CoreStack's FinOps engine analyses your entire cloud estate — scanning for idle resources, right-sizing opportunities, orphaned assets, and commitment gaps.
Your dedicated FinOps expert walks you through a board-ready cloud cost report — with a prioritised action plan and projected 12-month savings.
Most FinOps tools show you the problem. CoreStack fixes it — automatically, continuously, and across every cloud.
CoreStack doesn't produce a report and leave you to act on it. Its autonomous policy engine continuously monitors, alerts, and remediates — so savings compound over time rather than eroding after the first engagement.
AWS, Azure, and GCP in a single pane of glass — with unified cost allocation, governance policies, and chargeback. No tool-switching, no data gaps between clouds.
Cost optimisation and security compliance running simultaneously. When your CISO and CFO are both in the room, CoreStack is the only platform that answers to both — without two separate toolsets.

These are not estimates. They are audited outcomes from CoreStack customers.
Examity, the global leader in online proctoring with 3M+ assessments per year, was struggling with escalating cloud costs and limited resource visibility. After deploying CoreStack, continuous monitoring and granular cost visibility delivered a 40% cloud cost reduction within 60 days — recovering $1.5M that had been draining undetected.
Synopsys (20,000 staff, 100+ global offices) needed accurate cost allocation across AWS, Azure, and GCP for chargeback by project and business unit. CoreStack FinOps+ delivered 100% compliance across all mapped tags — eliminating custom scripting and giving full multi-cloud spend control out of the box.
A global real estate development company managing complex multi-cloud workloads achieved a 27% reduction in cloud costs through CoreStack's continuous rightsizing recommendations, idle resource detection, and commitment optimisation — without disrupting any running workloads.
A global FinServ company reduced cloud costs by 30% without compromising a single compliance requirement. CoreStack's unified FinOps + SecOps layer meant cost optimisation and PCI-DSS governance ran simultaneously — on one platform, replacing two separate tools.
"The partnership with CoreStack improves our clients' operational efficiencies, provides a better customer experience, and increases customer retention. Ultimately we've experienced bottom-line revenue growth."
Brian Castle Senior Manager of Managed Services Delivery, VirtusaHere is what customers moving to CoreStack say about the tools they left behind.
Since the Broadcom acquisition, customers report slower development, confusing support tiers, and rigid 12–36 month contracts at 2.2–2.5% of cloud spend. There is no Kubernetes cost visibility and no compliance story.
Apptio's TBM framework is powerful on paper — but engineers do not use it, implementation takes months, and the IBM acquisition has made contracts and roadmap opaque. Mindshare has dropped from 12.3% to 8.7% YoY.
Vantage is excellent for engineering-led cost visibility, but it has zero compliance, zero SecOps, and no MSP multi-tenancy. When your CISO, CFO, and compliance team enter the conversation, Vantage is not the answer.
Datadog CCM requires you to pay more Datadog to manage your Datadog spend. Finance teams cannot work in it, there is no compliance automation, and it deepens single-vendor lock-in. Datadog itself is often the fastest-growing line item in your cloud budget.
Most enterprises discover 15–30% recoverable waste in the first 30 days of a CoreStack assessment. The longer you wait, the more that compounds.
This is a conservative estimate. Your actual cloud wastage could be higher.
