Cloud Security Posture Calculator
Evaluate the maturity of your AWS, Azure, or GCP environment by assessing Identity, Network, Data, and Logging controls.
Misconfigurations are the leading cause of cloud data breaches. Cloud Security Posture Management (CSPM) is the process of identifying and remediating these risks. This tool provides a high-level assessment of your cloud environment against industry best practices (like the CIS Foundations Benchmark). By selecting your current implementation level across four key domains, it generates a Maturity Score and a prioritized roadmap for securing your cloud infrastructure.
Shared Responsibility Disclaimer
In the cloud, security is a shared responsibility.
- The provider is responsible for security of the cloud (physical data centers, hypervisors).
- You are responsible for security in the cloud (IAM policies, firewall rules, customer data).
- No cloud provider will automatically prevent you from making a bucket public.

How to use this calculator
Assess Identity & Access (IAM)
IAM is the new perimeter in the cloud. If an attacker steals a set of AWS access keys, they bypass your firewalls entirely. Select "Optimized" only if you use Single Sign-On (SSO), strictly enforce Multi-Factor Authentication (MFA), and use temporary credentials (roles) rather than long-lived static access keys.
Review Network Security
Just because the cloud is on the internet doesn't mean your databases should be. Select "Managed" if you use private subnets (VPCs) and basic security groups to restrict traffic. Select "Optimized" if you employ a Web Application Firewall (WAF), strict egress filtering, and Zero Trust micro-segmentation between application tiers.
Evaluate Data Protection
Cloud providers make encryption easy, but it's rarely on by default for everything. Choose "Optimized" if you use Customer Managed Keys (CMK) so you control the cryptographic material, run automated backup routines to immutable vaults, and have active Data Loss Prevention (DLP) scanning your storage buckets for PII.
Check Logging & Monitoring
If a breach happens in your cloud, will you know? CloudTrail (AWS) or Monitor (Azure) must be enabled across all regions to record API calls. Select "Optimized" if these logs are automatically forwarded to a Security Information and Event Management (SIEM) system that generates alerts for anomalous behavior (like launching GPU instances in a new region).
Analyze the Posture Tier
The tool outputs a maturity tier. "Critical" means you are one mistake (or one phishing email) away from a major breach. "Managed" means you have the basics down but are vulnerable to advanced attacks. "Optimized" means you treat infrastructure as code and secure it by design.
Prioritize Remediation
Don't try to fix everything at once. Use the "Cloud Security Roadmap" provided in the results to tackle issues sequentially. Always start with Identity (enforcing MFA and deleting root keys), followed closely by Data (blocking public access to storage buckets).
Advantages of this calculator
Provider Agnostic
Whether you use AWS, Microsoft Azure, or Google Cloud (GCP), the fundamental security principles are the same. This tool focuses on those universal domains (IAM, Network, Data, Logging) rather than vendor-specific jargon, making it useful for multi-cloud strategies.
Immediate Executive Visibility
Cloud consoles are notoriously complex. A CEO doesn't want to look at AWS JSON policies. This tool translates complex technical configurations into a single "Posture Score" (e.g., 65%) that non-technical executives can track quarter-over-quarter.
Highlights Misconfiguration Risks
Many IT teams assume that moving to the cloud automatically makes them secure. This calculator explicitly highlights that the customer is responsible for the configuration. It drives awareness of the Shared Responsibility Model.
Justifies CSPM Investment
If your score is low, it serves as business justification to purchase an automated CSPM tool (like Wiz or Prisma Cloud). Manual checks are impossible at scale; calculating a poor manual posture proves the need for automation.
Alignment with Frameworks
The four domains assessed directly map to the core tenets of the Center for Internet Security (CIS) Foundations Benchmarks, ensuring your high-level assessment aligns with rigorous, industry-standard auditing practices.

Q&A
What is CSPM?
Cloud Security Posture Management (CSPM) is a category of security tools designed to identify misconfiguration issues and compliance risks in the cloud automatically.
What is the Shared Responsibility Model?
It's the security framework used by all cloud providers. The provider secures the physical hardware and data centers, while the customer must secure the operating systems, network traffic, and data they put inside.
Why is a public S3 bucket dangerous?
If an AWS S3 bucket (or Azure Blob) containing sensitive data is misconfigured as 'Public,' anyone on the internet can read or download that data without needing a password. It is the cause of massive data breaches.
What is 'Least Privilege' in the cloud?
It means granting an identity (a user or a software application) only the exact, minimal permissions it needs to perform its task, and nothing more, to limit the blast radius if compromised.
Why are static access keys bad?
Static access keys don't expire. If a developer accidentally uploads them to GitHub, hackers can use them forever. You should use temporary, role-based credentials instead.
What does 0.0.0.0/0 mean in a firewall rule?
It means 'allow from anywhere on the internet.' While necessary for public web servers (port 443), allowing 0.0.0.0/0 on management ports like SSH (22) or RDP (3389) is highly dangerous.
What is a VPC?
A Virtual Private Cloud (VPC) is a logically isolated section of the cloud where you can launch resources in a virtual network that you define. It is the foundation of cloud network security.
Why do I need to encrypt data if the cloud provider is secure?
Encryption protects you against logical breaches. Even if someone gains access to the storage volume, they cannot read the data without the decryption keys, which you control.
What is CloudTrail?
AWS CloudTrail is a service that enables governance, compliance, and operational auditing. It logs every API call made in your account, providing a history of who did what, and when.
Can't I just use a traditional firewall in the cloud?
No. Cloud environments are highly dynamic. IP addresses change constantly. Cloud security relies on Identity (IAM) and Security Groups (attached to instances) rather than static perimeter firewalls.
What is a WAF?
A Web Application Firewall (WAF) inspects incoming HTTP traffic to block common web exploits, like SQL injection or cross-site scripting (XSS), before they reach your servers.
What is 'Configuration Drift'?
Configuration drift happens when resources are modified manually in the console, causing them to deviate from the secure, approved state defined in your Infrastructure as Code (IaC) templates.
What is an 'Immutable Backup'?
A backup that cannot be altered or deleted for a set period, even by an administrator. This is critical for recovering from ransomware attacks where the attacker attempts to delete all backups.
Should I enable MFA on the 'root' account?
Absolutely. The root account has unrestricted access to everything. Enforce MFA, lock the physical token in a safe, and never use the root account for daily tasks.
