Cloud Security Posture & Architecture
Cloud Security Posture & Architecture

Understand Your AWS Risk— and Fix What Matters First

Real AWS risk has a way of hiding—new accounts, services, permissions, and integrations can create exposure faster than periodic audits ever catch it. We built this to help you see it clearly and act with confidence. We help you combine cloud-security architecture, structured assessment, and read-only analysis through Securitain to show where risk exists, how controls interact, and which changes reduce the greatest business exposure.

Beyond the checkbox

Security Posture Is More Than a Compliance Score

A cloud environment can pass many benchmark checks and still contain serious risk—an encrypted workload with an over-accessible KMS key, a private resource reachable through an unexpected path, or a privilege-escalation route. Cloudain evaluates AWS as a connected architecture, not a collection of isolated findings.

What Cloudain does

What Cloudain Does

From establishing the current posture to designing a target state and validating remediation—architecture-led throughout.

Establish the Current Posture

Build a reliable view of the AWS environment to separate real gaps from intentional decisions.

Accounts & org structure
Prod / non-prod separation
Internet-facing services
Logging & security coverage

Review the Architecture, Not Only Settings

Assess how controls work together and where blast radius concentrates.

Organizations & IAM federation
VPC & network segmentation
KMS, encryption & secrets
CloudTrail, Config & detection

Identify Exposure & Attack Paths

Connect identity, network, policy, and data to determine whether a path is exploitable.

Public service + overprivileged role
Broad vendor trust to production
Secrets beyond app boundary
Pipeline role changing prod IAM

Design Secure Multi-Account Architecture

Design or improve the organization to reduce blast radius while staying manageable.

OUs & prod/non-prod split
Security Tooling & Log Archive
Control Tower & SCPs
Centralized logging & security

Prioritize Remediation by Business Impact

Not every failed control is equal—focus first on high-impact, exploitable risk.

Exploitability & prerequisites
Criticality & data sensitivity
Exposure & blast radius
Compensating controls & effort

Create a Target-State Architecture

A practical target state translated into phased implementation, not a conceptual diagram.

Trust & network boundaries
Data protection & detection
Workload & CI/CD security
Backup & IR readiness

Support Remediation & Validation

Continue beyond assessment to implement changes, then retest and document closure.

Segmentation & private access
Encryption & KMS improvements

Design Secure Multi-Account Architecture

For organizations growing beyond a few AWS accounts, Cloudain designs or improves the organization, landing zone, guardrails, and centralized logging—reducing blast radius while keeping the platform manageable for engineering teams.

Engagement flow

How the Engagement Works

A connected path from baseline and architecture review to attack-path analysis, prioritization, target state, and validation.

01

Baseline the Posture

Build a reliable current-state view across accounts, identities, networks, data, and controls.

02

Review the Architecture

Assess how controls interact and where trust boundaries and blast radius concentrate.

03

Map Attack Paths

Connect identity, network, policy, and data to reveal exploitable paths and impact.

04

Prioritize by Impact

Rank findings by exploitability, criticality, exposure, and remediation effort.

05

Design the Target State

Define a practical, phased target architecture across identity, network, and data.

06

Remediate & Validate

Implement changes, retest the environment, and document closure evidence.

Read-only analysis

How Securitain Supports the Engagement

Securitain provides a read-only analysis layer across connected AWS accounts—helping evaluate findings consistently. Consultants validate each important finding against workload purpose, business context, exploitability, and compensating controls. It supports architectural judgment; it doesn’t replace it.

Ways to engage

Typical Engagement Options

Start where it matters most—from a focused posture assessment to a continuous, Securitain-supported program.

AWS Security Posture Assessment

A focused review of identity, exposure, data protection, logging, workloads, and governance.

AWS Security Architecture Review

A deeper look at application, account, network, identity, and data architecture.

Multi-Account Security Foundation

Design or improve the organization, landing zone, guardrails, logging, and delegated security.

Continuous Security Posture Program

Recurring assessment, change review, risk tracking, and remediation validation.
