CoreStack

Profile

CoreStack is an AI-powered multi-cloud governance platform designed to unify financial operations, security compliance, and operational management across AWS, Azure, Google Cloud, and Oracle Cloud environments. The platform addresses enterprise challenges in managing fragmented cloud infrastructure through its CR360 intelligence system, which provides comprehensive visibility into every cloud resource's context, relationships, and dependencies. CoreStack has achieved recognition in Gartner's Magic Quadrant for Cloud Management Platforms and serves over 780 organizations globally, including managed service providers, enterprises, and government agencies. The platform transforms cloud governance from reactive, manual processes into proactive, autonomous operations through advanced automation and intelligent remediation capabilities.

Focus

CoreStack solves the fundamental challenge of governing multi-cloud infrastructure where native cloud tools create operational blind spots, fragmented financial accountability, and complex compliance management. Organizations struggle with siloed governance tools that require manual data reconciliation across providers, leading to budget overruns, security vulnerabilities, and compliance violations. The platform consolidates governance into a unified system that applies consistent policies across environments while accounting for business criticality, compliance requirements, and financial impact. CoreStack serves platform engineers, cloud architects, FinOps practitioners, and security teams who need to enforce governance without impeding operational agility, enabling them to optimize costs, maintain continuous compliance, and automate operational workflows across heterogeneous cloud environments.

Background

CoreStack was founded in 2014 by Ezhilarasan Natarajan and three co-founders with extensive cloud technology experience. The company initially operated without external funding until securing angel investments in 2017, followed by institutional capital including a Series B round and growth financing from Post Road Group. CoreStack has expanded through strategic acquisitions, notably acquiring Karthik Consulting to strengthen federal government capabilities and continuous Authority to Operate expertise. The platform demonstrates active maintenance through continuous product development, including major platform enhancements and new capabilities. CoreStack maintains operations from Bellevue, Washington, with additional offices supporting global customers and maintains partnerships with major cloud providers as a recognized technology partner.

Main features

Unified multi-cloud financial governance

CoreStack's FinOps+ module provides consolidated cost visibility across multiple cloud providers through FOCUS-compliant dashboards that automatically translate native AWS, Azure, GCP, and Oracle billing formats into standardized representations. The platform eliminates manual cost reconciliation by aggregating spending data across subscriptions and accounts, enabling analysis by product category, resource group, region, or custom tags. Organizations can configure multi-tier chargeback models with custom pricing logic, markups, and negotiated contract terms through BillOps capabilities. The system identifies optimization opportunities through usage-based recommendations like right-sizing instances and rate-based strategies including reserved capacity purchases, while anomaly detection automatically flags unusual spending patterns before they escalate into budget overruns.

Continuous security and compliance automation

The SecOps module consolidates security threats, vulnerabilities, and compliance findings from disparate tools into a unified, prioritized view that reduces alert fatigue. CoreStack automatically assesses cloud resources against thousands of built-in policies covering ISO/IEC, NIST, GDPR, FedRAMP, HIPAA, PCI-DSS, and CIS standards, identifying violations without manual evaluation. The platform provides autonomous remediation capabilities that automatically correct policy violations—such as enabling encryption, closing overly permissive security groups, or applying required tags—within predefined governance frameworks. This transforms compliance from episodic audit exercises into continuous, self-healing operations that maintain security posture while accelerating remediation processes and reducing manual security team workload.

Intelligent cloud application protection

Graphion, CoreStack's Cloud-Native Application Protection Platform, unifies Software Bill of Materials data from development with Infrastructure Bill of Materials from operations, providing end-to-end traceability from source code through runtime. The platform constructs a continuously updated, multi-layered graph mapping code, containers, Kubernetes clusters, APIs, identities, and configurations into a unified intelligence model. An ontology-driven Large Cloud Governance Model constrains AI interpretation to reduce hallucinations and provide contextually relevant security recommendations that account for business criticality and operational intent. Graphion shows how vulnerabilities relate and propagate through infrastructure, enabling organizations to identify supply-chain weaknesses and prioritize remediation based on actual business risk rather than generic severity scores.
