A Cloud Infrastructure Audit is a read-only, white-box review of your Azure, AWS, or GCP environment that finds misconfigurations, over-privileged IAM roles, and exposed services before attackers do.

Cloud services offer enormous flexibility, but that flexibility comes with risk. Misconfigured storage buckets, overly permissive IAM roles, and exposed management interfaces are among the most common causes of cloud security incidents. A Cloud Infrastructure Audit reviews your cloud environment with a read-only account to identify exactly these issues before attackers do.

Supported platforms: Azure, AWS, and GCP. For Azure environments, cloud IAM misconfigurations are frequently intertwined with Entra ID role assignments and Conditional Access, both are often reviewed together.

Scope

This audit is performed as a white-box engagement using a read-only account and standard tooling (ScoutSuite, manual review). The following areas are covered:

Identity and Access Management: role assignments, over-privileged accounts, service principals, least-privilege review
Storage and data exposure: public buckets/blobs, access policies, sensitive data exposure
Virtual Network Configuration: security groups, network ACLs, firewall rules, exposure of management ports
Logging and Monitoring: audit log configuration, alerting, detection coverage
Security Settings: Defender/Security Hub/Security Command Center configuration, encryption at rest and in transit
Service-specific hardening: configuration of the cloud services actively used in your environment

Why

Cloud environments are a frequent source of breaches, often because default configurations are not hardened
IAM mistakes (e.g. overly broad roles, unused service accounts with high permissions) are the most common cloud security gap
A read-only configuration review can surface critical exposures in hours that might otherwise go unnoticed for months

Typical findings include a CI/CD service principal with Contributor or Owner rights far beyond what its pipeline needs, storage accounts or buckets left publicly readable after a one-off data export, and stale guest accounts retaining access long after a project ends. None of these require exploiting a vulnerability. They are configuration mistakes visible to anyone who knows where to look, which is exactly why a read-only review finds them so quickly.

Why VidraSec 🦦

I have conducted Cloud Infrastructure Audits across Azure, AWS, and GCP environments. My background in identity and access management, particularly in the Microsoft stack, extends naturally into cloud IAM, where many of the same misconfigurations appear.

Typical Duration

3 to 5 days (scope-dependent, depends on the number and complexity of cloud services in use). Reporting takes roughly 30 to 50% of the test time on top.

Typical Price

from 7,000 €

The final price depends on the scope of the project and the maturity level of your IT security. It is calculated individually based on the required effort.

Deliverables

Every engagement includes:

Written findings report with all misconfigurations, prioritized by severity, with remediation steps
Management summary tailored to your audience (technical or executive)
Live debriefing to walk through findings and answer questions
Retesting after remediation available on request

See example reports for what a VidraSec report looks like.

Compliance

Directly relevant for NIS2 and ISO 27001. Cloud configuration is increasingly scrutinized in information security management reviews.

Frequently asked questions

Which cloud platforms does VidraSec audit?

Azure, AWS, and GCP. The audit uses a read-only account and a combination of automated tooling such as ScoutSuite and manual expert review.

Is a Cloud Infrastructure Audit the same as a cloud penetration test?

Not quite. A configuration audit reviews your environment from a read-only account to find misconfigurations efficiently. A cloud penetration test actively attempts to exploit issues. For most organizations the configuration audit surfaces the highest-impact problems fastest.

How long does a Cloud Infrastructure Audit take?

Typically 3 to 5 days depending on the number and complexity of cloud services in use, plus roughly 30 to 50 percent of that time for reporting.

How much does a Cloud Infrastructure Audit cost?

From 7,000 euros. The final price depends on scope and the maturity level of your environment and is calculated individually.
