Cloud Security Assessment for AWS, Azure and Google Cloud
Most cloud breaches come from configuration, not from the cloud provider being hacked. Common causes are an identity with too much access, a storage bucket left public, a database exposed to the internet or logging switched off. A cloud security assessment reviews how your AWS, Azure or Google Cloud accounts are actually set up and shows you what to fix first.
Mutex Systems combines automated benchmark scanning with expert review of identity, network, data protection, logging and workload security. We have deep Microsoft Azure experience and also cover AWS and GCP. Findings are benchmarked to CIS and mapped to ISO 27001, SOC 2 and PCI DSS, then kept under continuous watch in grComply.

The risk behind this service
Based on incidents and figures in our UK & Europe threat report.
- Attackers increasingly target cloud identities and control planes, because one over-privileged role can expose everything.
- Cloud estates change daily. A configuration that was safe at go-live drifts as teams add services.
- Customers and auditors now ask specifically how cloud environments are secured: ISO 27001 control 5.23, SOC 2 and PCI DSS all expect evidence.
Who this is for
- SaaS companies running production on AWS, Azure or GCP
- Organisations after a cloud migration
- Fintechs and banks using cloud under SBP cloud outsourcing rules
- Teams preparing for ISO 27001, SOC 2 or PCI DSS audits
- Companies with multiple accounts, subscriptions or projects
- Kubernetes and container users

What a cloud security assessment changes
How an expert cloud review compares with relying on default settings and native dashboards alone.
| Factor | Default settings and dashboards | ● With a Mutex cloud assessment |
|---|---|---|
| Risk | Over-privileged identities and public resources go unnoticed. | Attack paths found and ranked by real business impact. |
| Cost | Unused resources, duplicate tools and noisy alerts waste money. | Clean-up recommendations often reduce cloud and tooling spend. |
| Audit readiness | Evidence for cloud controls gathered by hand before each audit. | Findings mapped to ISO 27001, SOC 2 and PCI DSS controls. |
| Engineering effectiveness | Security fixes arrive late and disrupt releases. | Guardrails and IaC checks prevent issues before deployment. |
| Visibility | Logging gaps mean incidents cannot be investigated. | Logging and detection coverage confirmed across accounts. |

05Compliance
Frameworks and regulations this supports
CIS Controls
CIS benchmarks are the baseline for cloud configuration checks.
CSA CCM & STAR
The cloud-specific control matrix and assurance registry.
ISO 27017 & 27018
Cloud security and cloud privacy controls that extend ISO 27001.
ISO 27001:2022
Control 5.23 covers information security for the use of cloud services.
SOC 2
Cloud configuration evidence supports the Security and Availability criteria.
PCI DSS v4.0
Cloud-hosted cardholder environments need segmentation and logging evidence.

What is a cloud security assessment?
It is a review of how your cloud accounts are configured and used, covering identity, network exposure, data protection, logging and workloads. It finds misconfigurations and attack paths and gives you prioritised fixes.
Is the cloud provider not responsible for security?
Partly. Under the shared responsibility model, AWS, Microsoft and Google secure the underlying infrastructure. You are responsible for how you configure identities, networks, data and services, and that is where most breaches happen.
Do you need admin access to our cloud?
No. We use read-only access for the assessment. Hands-on cloud penetration testing, if you want it, is scoped and authorised separately.
How is this different from cloud penetration testing?
An assessment reviews every configuration broadly. A penetration test tries to exploit specific paths to prove impact. Many clients do the assessment first and then test the highest-risk paths.
How long does it take?
A single account or subscription can be assessed in days. Large multi-account estates take longer. We confirm the timeline after scoping.
Can you help us fix the findings?
Yes. Our cloud and DevOps engineers can implement fixes, build guardrails and add IaC checks to your pipelines.
How much does a cloud security assessment cost?
It depends on the number of accounts, subscriptions and workloads and whether testing is included. We send a fixed-scope proposal after a short scoping call.
