Attack Readiness

Moving to the cloud shifts responsibility.
It does not remove it.

A security review of your AWS, Azure, or GCP configuration, architecture, and access management. Misconfigurations found before they become breaches.

What is a cloud security assessment?

You know you have cloud infrastructure running. You have IAM roles, storage buckets, and network configurations to secure. You get a clear picture of your cloud security posture with prioritised recommendations aligned to your platform and architecture choices. A cloud security assessment combines automated configuration checks against CIS Benchmarks with manual IAM analysis and architecture review. You receive an actionable report covering misconfigurations, privilege escalation paths, and architecture risks.

About this service

Cloud Security Assessment: configuration and architecture reviewed

Cloud migration shifts the security responsibility but does not remove it. Misconfigurations in AWS, Azure, or GCP are among the most common causes of data breaches. A cloud security assessment examines your cloud configuration, architecture, and access management for vulnerabilities and best practice deviations.

The team combines automated configuration checks with manual analysis. Automated tools detect known misconfigurations quickly but miss context. Is that publicly accessible S3 bucket an intentional choice or a mistake? Manual analysis provides that context and identifies risks that exist only in your specific architecture.

The assessment covers the shared responsibility model: which security measures are the cloud provider's responsibility and which are yours? Many organisations underestimate their own responsibility, especially around identity and access management, network segmentation, and logging.

Why this matters

Three cloud security risks that cause real breaches

  • Over-privileged IAM roles are the attacker's favourite

    Overly broad IAM policies, unused admin roles, and service accounts with excessive permissions create privilege escalation paths that attackers exploit to gain full account control from a single compromised credential.

  • Publicly exposed storage is found by scanners in minutes

    Misconfigured S3 buckets, Azure Blob containers, and GCS buckets continue to expose sensitive data. Automated scanners index public cloud storage daily. If yours is open, it will be found.

  • Logging gaps make breaches invisible

    Without proper CloudTrail, Azure Monitor, or GCP logging configured, attackers can operate for months undetected. Many organisations discover a breach only when the damage is already done.

What gets reviewed

Scope of the cloud security assessment

Identity and Access Management (IAM): roles, policies, MFA, service accounts
Network configuration: VPCs, security groups, firewalls, peering
Storage security: bucket policies, encryption, access control
Compute: instance configuration, hardening, patching
Logging and monitoring: CloudTrail/Azure Monitor/GCP Logging
Secrets management: key vaults, rotation, hardcoded credentials
Container and Kubernetes security (if applicable)
Compliance: CIS Benchmarks, cloud-native security tools
Multi-cloud and hybrid architectures
Methodology

How DEFION conducts a cloud security assessment

01

Scoping

Inventory of cloud accounts, regions, services, and architecture overview.

02

Automated configuration check

Scan against CIS Benchmarks and cloud-native best practices for broad coverage.

03

Manual IAM analysis

Review of roles, policies, trust relationships, and privilege escalation paths.

04

Architecture review

Assessment of network segmentation, data flows, and security architecture decisions.

05

IaC review (optional)

Review of Terraform, CloudFormation, or Bicep templates for security issues before deployment.

06

Reporting and prioritisation

Report with findings categorised by risk and remediation complexity, including a prioritised action plan.

What you receive

Deliverables

  • Executive summary with risk distribution
  • Technical report with findings per cloud service
  • CIS Benchmark compliance overview
  • IAM risk analysis with privilege escalation paths
  • Architecture diagram with security observations
  • Prioritised remediation plan
  • Report debrief
Target audience

Who is a cloud security assessment for?

Any organisation with cloud infrastructure needs to understand what is exposed, what is misconfigured, and where the privilege escalation paths lie. The more cloud you have, the more critical visibility becomes.

  • Organisations that recently migrated to the cloud
  • Companies with a growing cloud footprint and limited cloud security visibility
  • DevOps teams that want to validate their Infrastructure as Code
  • Organisations that need to demonstrate cloud-specific compliance
  • Multi-cloud environments that need consistent security across providers
Frequently asked questions

FAQ

Which cloud platforms are supported?
AWS, Microsoft Azure, and Google Cloud Platform. Multi-cloud and hybrid environments are also supported. For less common platforms (Oracle Cloud, Alibaba Cloud) we discuss the options.
Do you need access to our cloud accounts?
Yes, in the form of read-only access. The team works with minimal permissions and makes no changes to your environment. Exact permissions are agreed and documented in advance.
Can this be combined with a pentest?
Yes. A cloud security assessment focuses on configuration and architecture. A pentest on the cloud environment goes further and actively attempts to exploit vulnerabilities. The combination gives the most complete picture.
How long does a cloud security assessment take?
Depending on scope: for a single AWS account with limited services, 3 to 5 days. For complex multi-account or multi-cloud environments, 10 to 15 days.
What if we use Infrastructure as Code (Terraform, CloudFormation)?
The team can also review IaC templates for security issues. This catches problems before they reach production and is a valuable addition to runtime analysis.
