Overview

The cloud has transformed how organizations operate—but it's also introduced new security challenges. Misconfigured cloud resources and improper identity configurations are now among the leading causes of data breaches. The shared responsibility model means you can't simply trust your cloud provider to keep you secure. Our cloud security services help organizations harness the power of cloud computing without sacrificing security. A cornerstone of our approach is **Identity and Access Management (IAM)**—because in cloud environments, identity is the new perimeter. We design and implement robust IAM strategies including: • **Cloud IAM Architecture**: Role-based access control (RBAC), attribute-based access (ABAC), and least-privilege policies for Azure, AWS, and GCP • **Hybrid Identity Solutions**: Seamless integration between on-premises Active Directory and cloud identity providers (Azure AD/Entra ID, AWS IAM, Okta) • **Zero Trust Implementation**: "Never trust, always verify" architecture with continuous authentication and micro-segmentation • **Privileged Access Management (PAM)**: Securing administrative access to cloud resources with just-in-time (JIT) access and session monitoring • **Multi-Factor Authentication (MFA)**: Strong authentication deployment across all cloud services and applications • **Service Principal & API Security**: Managing machine identities, service accounts, and API keys securely Whether you're planning a cloud migration, optimizing existing deployments, or trying to achieve compliance in cloud environments, we bring deep expertise across Azure, AWS, GCP, and Microsoft 365.

What We Deliver

Tangible outcomes and deliverables from our engagement.

IAM Architecture Design

Comprehensive identity strategy including RBAC/ABAC models, role definitions, and least-privilege access policies.

Cloud Security Architecture

Secure cloud infrastructure design with network segmentation, identity integration, and security controls.

Zero Trust Assessment & Roadmap

Current state evaluation and phased plan for implementing Zero Trust principles across your environment.

Security Baseline Configs

Hardened configuration templates for Azure, AWS, or M365 aligned with CIS benchmarks and IAM best practices.

Landing Zone Design

Secure, scalable foundation for cloud workloads with proper identity governance, segmentation, and controls.

Hybrid Identity Integration

Architecture and implementation for seamless identity across on-premises and cloud environments.

Cloud Security Roadmap

Phased implementation plan for cloud security improvements, IAM maturity, and Zero Trust adoption.

Compliance Mapping

Documentation mapping cloud and IAM controls to regulatory requirements (HIPAA, PCI, SOC 2, FedRAMP).

Our Process

A proven methodology that delivers results.

1

Discovery & Asset Inventory

Inventory cloud assets, identity providers, access patterns, and existing IAM configurations. Understand business requirements and security objectives.

2

Security & IAM Assessment

Evaluate current configurations, identity architecture, and access controls against CIS benchmarks, NIST 800-53, and Zero Trust principles.

3

Architecture Design

Develop target-state security architecture including IAM strategy, landing zones, identity governance, network design, and Zero Trust roadmap.

4

Implementation

Deploy identity controls, configure RBAC/PAM, harden cloud configurations, and implement monitoring and logging.

5

Validation & Testing

Verify security controls through penetration testing, access reviews, and compliance validation.

6

Documentation & Training

Document architecture decisions, IAM policies, and train your team on secure cloud and identity operations.

Ideal For

  • Organizations planning cloud migrations
  • Companies with existing cloud environments needing security review
  • Businesses adopting Zero Trust security models
  • Organizations with hybrid cloud and on-premises environments
  • Companies needing IAM architecture for cloud tenants
  • Businesses pursuing compliance in cloud (HIPAA, PCI, SOC 2, FedRAMP)
  • Organizations adopting multi-cloud strategies
  • Development teams building cloud-native applications
  • Companies with Microsoft 365 needing security optimization

What to expect

Three engagement shapes most clients pick from. We scope and fixed-bid before signature — no open-ended T&M.

Cloud & IAM Assessment

3–4 week fixed-bid

Practices or healthcare-tech firms running Microsoft 365 (most common), Google Workspace, or single-tenant AWS/Azure that need a defensible posture review — typically before an audit, after a misconfiguration incident, or as input into a cyber-insurance renewal.

Configuration review against CIS Microsoft 365 Foundations Benchmark, CIS AWS Foundations Benchmark, or CIS Azure Foundations — plus IAM architecture review, Conditional Access analysis, and external attack-surface check.

Included

  • CIS-benchmarked configuration review (M365, AWS, or Azure)
  • IAM architecture and Conditional Access policy review
  • External attack-surface scan (subdomains, exposed services, leaked credentials)
  • Prioritized remediation roadmap with owners
  • Executive summary and technical findings report

Not included (scoped separately)

  • Multi-cloud or multi-tenant scope (priced per additional environment)
  • Application-layer security testing (refer-out)

Cloud Architecture Design

4–8 week fixed-bid

Organizations migrating to cloud, consolidating tenants post-M&A, or rebuilding identity for Zero Trust readiness. Common trigger: insurance carrier or HHS-OCR asking for documented Zero Trust roadmap.

Secure-by-design architecture: landing zone topology, IAM strategy, Zero Trust roadmap aligned with NIST SP 800-207, and implementation guidance your engineering team or MSP can execute.

Included

  • Target architecture (landing zone, network, identity)
  • IAM strategy with role / group / policy taxonomy
  • NIST SP 800-207 Zero Trust roadmap (12-month phased plan)
  • Implementation guidance for your engineering team or MSP
  • Architecture decision records (ADRs) for each major call

Cloud Security Retainer

Monthly retainer · 6-month minimum

Organizations with ongoing cloud-security operational needs — quarterly access reviews, monthly Conditional Access policy refinement, change reviews on risky migrations.

Ongoing senior advisory with quarterly access reviews, monthly Conditional Access policy refinement, change reviews for risky migrations, and on-call advisory for cloud-related decisions.

Included

  • Quarterly access reviews (privileged identities + standing access)
  • Monthly Conditional Access policy review
  • Change review for material cloud migrations or new tools
  • On-call advisory for cloud-related security decisions

Each engagement is fixed-bid against a written scope. We publish methodology, not pricing — every quote is custom to your environment, regulated obligations, and timeline.
