## Key points

- Immediate impact: Security teams face widespread cloud misconfigurations across multi-cloud environments, complicating threat posture management.
- Affected systems: AWS, Microsoft Azure, and Google Cloud Platform environments, specifically regarding IAM and storage services.
- Remediation: Prioritize multi-factor authentication enforcement and implement consistent posture assessment tools across all cloud providers.

## Overview of Multi-Cloud Misconfigurations

Managing security across multiple cloud providers presents distinct challenges because each platform fails in unique ways. According to the [2026 Cloud Security Index](https://thehackernews.com/2026/09/your-cloud-security-checklist-doesnt.html) published by Intruder, an analysis of misconfiguration data across 3,000 organizations reveals that risk profiles across AWS, Azure, and Google Cloud share almost nothing in common. 

Intruder categorized cloud misconfigurations into six core areas: weak identity and access management ([IAM](/glossary#iam)), missing logging, misconfigured services, permissive firewalls, exposed services, and weak [encryption](/glossary#encryption). While weak IAM controls and missing logging are near-universal issues affecting between 80% and 98% of accounts regardless of provider, other risk vectors diverge sharply depending on the underlying platform.

## Provider-Specific Risk Profiles

The research highlights stark differences in how security posture varies across the major hyperscalers:

* **Amazon Web Services (AWS):** AWS leads in prevalence across five of the six risk categories, driven largely by its massive range of services, which introduces more configuration options. Common findings include S3 buckets failing to enforce HTTPS and complex IAM policies permitting [privilege escalation](/glossary#privilege-escalation) in 83% of evaluated accounts.
* **Microsoft Azure:** Storage accounts lacking baseline [hardening](/glossary#hardening) represent the top issues in Azure environments. Furthermore, over half of accounts maintain Entra ID users without multi-factor authentication ([MFA](/glossary#mfa)), creating risks that cascade into Microsoft 365 and third-party SaaS applications.
* **Google Cloud Platform (GCP):** GCP demonstrates lower prevalence across most categories, which may stem from a Shared Fate model implementing more secure defaults. However, identity remains a challenge, with over three-quarters of accounts lacking OS Login controls.

## Organizational Impact and Remediation

Interestingly, risk prevalence for categories like permissive firewalls and exposed services tends to drop as organizations grow larger. However, weak IAM controls defy this trend, impacting 87% of small-to-medium enterprises, 95% of midmarket organizations, and 98% of large enterprises. Because a single overprivileged identity can bypass hardened perimeter controls, security teams must prioritize identity hygiene.

To address multi-cloud complexity, organizations should adopt the following mitigation strategies:

* Implement automated posture management tools that provide consistent visibility across AWS, Azure, and GCP.
* Enforce mandatory multi-factor authentication across all identity providers, including Microsoft Entra ID.
* Regularly audit IAM roles and remove policies that permit unintended privilege escalation paths.
