What Is Cloud Security Consulting?

Cloud security consulting (also called cloud security assessment or cloud security advisory) is the expert-led process of identifying and remediating the security misconfigurations, access control weaknesses, and compliance gaps in your cloud environments - AWS, Azure, Microsoft 365, and GCP.

Unlike automated scanning tools that generate thousands of findings with no business context, our consulting engagements are led by a former Microsoft Security Consulting team member who interprets every finding, filters false positives, and delivers a prioritised remediation plan your team can act on immediately.

The shared responsibility model means your cloud provider is NOT responsible for your misconfigurations, your access controls, your data encryption settings, or your compliance posture. Cloud security consulting addresses exclusively the controls that are your responsibility.

The Shared Responsibility Model

The most important concept in cloud security - and the most frequently misunderstood. Every cloud breach that makes the news is a failure in the customer's half of this model.

Cloud Provider Secures

What AWS, Azure, and GCP are responsible for

Physical data centre security
Hardware and server infrastructure
Hypervisor and virtualisation layer
Global network infrastructure between regions
Availability and uptime of cloud services
Platform software patching for managed services

You Are Responsible For

Where breaches actually happen

Identity and access management (IAM) - roles, policies, permissions
Security group and firewall configuration
Data encryption - at rest and in transit
Operating system and application patching on IaaS
Security configuration of all cloud services you use
Compliance with regulations - HIPAA, PCI DSS, GDPR, SOC 2
Monitoring and logging configuration - off by default on most platforms
Multi-factor authentication for admin and privileged accounts

Cloud shared responsibility model - provider vs customer security responsibilities

Cloud Security Consulting for AWS, Azure, M365, and GCP

Each major cloud platform has a distinct security model, distinct default settings, and distinct attack vectors. Generic security tools miss the platform-specific misconfigurations that cause breaches.

Amazon Web Services

AWS Security Consulting

AWS is the world's largest cloud platform - and the most frequently targeted. The most common AWS security failures are public S3 buckets, overpermissioned IAM roles, disabled CloudTrail logging, and unrestricted security groups.

IAM policy audit - least privilege enforcement

S3 bucket access review and public exposure remediation

EC2 and RDS security group and network ACL review

VPC network segmentation and flow log configuration

CloudTrail, GuardDuty, and Security Hub activation

KMS encryption configuration for data at rest

Lambda and serverless security configuration

AWS Organisations multi-account security baseline

Microsoft Azure + Microsoft 365

Azure and M365 Security Consulting

Microsoft 365 and Azure represent the most complex cloud security environment most businesses operate in - and the one where Atlant Security has the deepest expertise. Our founder served on Microsoft's Security Consulting team.

Entra ID (Azure AD) - MFA, Conditional Access, PIM

Microsoft Defender for Office 365 configuration

Exchange Online anti-phishing and email authentication

SharePoint and OneDrive external sharing controls

Teams security settings and meeting policies

Azure storage account and blob access review

Defender for Cloud posture score improvement

Microsoft Sentinel SIEM configuration

Google Cloud Platform

GCP Security Consulting

GCP's security model shares the same fundamental shared responsibility principles as AWS and Azure but implements them through its own identity, networking, and storage models that require platform-specific expertise.

GCP IAM policy audit and least-privilege enforcement

Cloud Storage bucket access and public exposure review

Compute Engine firewall rules and VPC configuration

Google Kubernetes Engine (GKE) security hardening

Cloud Logging and Security Command Center activation

Google Workspace admin console security settings

Workspace MFA, SSO, and session management

Cloud SQL and database access controls

Multi-cloud security across AWS, Azure, and Google Cloud Platform

10 Cloud Misconfigurations Attackers Exploit Most Frequently

These are the specific misconfigurations found in the majority of cloud security assessments - the ones attackers scan for automatically and exploit within hours of discovery.

Publicly Accessible Storage (S3, Blob, GCS)

Public S3 buckets, Azure storage accounts with public blob access, and GCS buckets with public object access are consistently among the top causes of large-scale data exposures.

Overpermissioned IAM Roles and Service Accounts

IAM roles with wildcard permissions (Action: *, Resource: *) give any service that assumes them complete control over your cloud environment.

No MFA on Root / Global Admin Accounts

The root AWS account, Azure Global Administrator, and GCP Organisation Admin are the highest-privilege accounts. These accounts frequently lack MFA enforcement.

Unrestricted Security Groups and Inbound Rules

Security groups with 0.0.0.0/0 inbound rules on SSH (port 22), RDP (port 3389), or database ports expose compute instances directly to the internet.

Logging and Monitoring Disabled or Incomplete

AWS CloudTrail, Azure Monitor, and GCP Cloud Logging are disabled or misconfigured in a significant proportion of environments. Without logging, breaches go undetected for months.

Unencrypted Data at Rest and in Transit

Cloud storage, databases, and snapshots that are not encrypted expose data in the event of unauthorized access. Most platforms require explicit configuration to enable encryption.

Publicly Accessible Snapshots and Backups

AWS EBS snapshots, RDS snapshots, and Azure VM disk snapshots set to public are accessible by any account - including those owned by attackers.

Default Credentials and Hardcoded Secrets

Database instances deployed with default credentials and API keys hardcoded into application source code or configuration files are found in the majority of cloud environments.

Missing or Weak Conditional Access Policies

Entra ID Conditional Access policies - which enforce MFA, restrict access by location or device compliance, and block legacy authentication - are disabled or minimally configured.

Overpermissioned Third-Party Integrations

Third-party SaaS tools, CI/CD pipelines, and developer tools connected to your cloud frequently use API keys with excessive permissions - often full administrator access.

Cloud security vulnerabilities and misconfigurations that attackers exploit

Microsoft 365: 280+ Security Settings

Microsoft 365 has over 280 security settings across Exchange Online, Teams, SharePoint, OneDrive, Entra ID (formerly Azure AD), Microsoft Defender for Office 365, and the Microsoft 365 Compliance Center. The majority of these settings ship in their off or default state at tenant activation.

Every Atlant Security M365 engagement reviews and hardens all 280+ settings. Our founder served on Microsoft's Security Consulting team - this is not generic cloud consulting. This is insider knowledge of the platform applied directly to your environment.

Cloud Security and Compliance - 6 Frameworks, One Assessment

Cloud security and compliance are not separate programmes. The security controls that protect your cloud environment are the same controls that satisfy your compliance framework.

SOC 2 Type II in the Cloud

SOC 2 requires controls across Security, Availability, Processing Integrity, Confidentiality, and Privacy. In cloud environments, the majority of these controls are implemented through cloud configuration - IAM, encryption, logging, and change management.

ISO 27001 Cloud Controls

ISO 27001 Annex A includes cloud-specific controls in domains covering access control, cryptography, operations security, communications security, and supplier relationships.

HIPAA Cloud Security

Healthcare organisations using AWS, Azure, or GCP to store or process Protected Health Information (PHI) must operate under a Business Associate Agreement (BAA) with their cloud provider and implement all required safeguards.

PCI DSS Cloud Compliance

PCI DSS requirements apply to cloud environments used to process, store, or transmit cardholder data. The shared responsibility model creates specific PCI DSS scoping challenges.

NIST 800-53 in the Cloud

NIST 800-53 is the control framework mandated for US federal systems (FedRAMP) and increasingly adopted by regulated private-sector organisations.

GDPR Cloud Data Protection

GDPR requirements apply to cloud environments handling personal data of EU residents - data residency, data processing agreements, and right-to-erasure implementation in cloud storage.

Cloud Security Consulting FAQ

Do you support multi-cloud environments?

Yes, we specialize in securing complex multi-cloud and hybrid-cloud architectures, ensuring consistent security policies across all platforms.

Can you help us automate our cloud security?

Absolutely. We focus on 'Security-as-Code' and can help you implement automated guardrails using tools like Terraform, CloudFormation, or Azure Bicep.

How much does a cloud security assessment cost?

Single-platform assessments (AWS, Azure, or Microsoft 365) start from $4,000 and typically take 5-10 business days. Multi-cloud assessments take 2-3 weeks.

Do you have Microsoft insider expertise?

Yes. Our founder is a former member of the Microsoft Security Consulting team, giving us deep insider knowledge of Microsoft 365, Azure AD, and the entire Microsoft security ecosystem - including all 280+ security settings.

What are the most common cloud vulnerabilities you find?

The top issues we consistently find include: overly permissive IAM policies, unencrypted data at rest, publicly exposed storage buckets, missing MFA on privileged accounts, outdated security group rules, and insufficient logging and monitoring.

Do you work with our cloud provider's security tools?

Yes. We leverage native security tools (AWS Security Hub, Azure Defender, GCP Security Command Center) alongside third-party solutions to provide comprehensive coverage.

Can you help us implement the changes you recommend?

Absolutely. Unlike firms that just hand you a report, we provide hands-on implementation support. We can configure security controls, write Infrastructure-as-Code templates, and work alongside your DevOps team.

What is the shared responsibility model and why does it matter?

The shared responsibility model defines what your cloud provider secures and what you must secure yourself. The provider is responsible for physical infrastructure, hardware, hypervisors, and platform availability. You are responsible for every configuration, access control, and data protection decision. Every major cloud breach is a failure in the customer's half of this model, not the provider's.

Why does my cloud environment need assessment if AWS or Azure is already secure?

Because AWS, Azure, and Google being secure does not mean your cloud environment is secure. Microsoft 365 activates with over half of its 280+ security settings in their off or default state. AWS leaves security groups open, CloudTrail disabled, and GuardDuty unactivated until you configure them. The cloud provider secures their infrastructure - not your configurations.

How long does a cloud security assessment take?

A typical Microsoft 365 or single-platform AWS or Azure assessment can be completed within 5-10 business days. Multi-cloud environments spanning multiple platforms, accounts, and regions may take 2-3 weeks. Quick wins like MFA deployment, logging enablement, and closing public storage can be implemented within days.

Can you help us secure our cloud environment after a breach?

Yes. If your cloud environment has been breached, we provide incident response support alongside cloud security hardening: contain the incident, investigate root cause and scope of data access, implement emergency hardening controls to prevent re-entry, then conduct a comprehensive security assessment to close all remaining gaps.
