What is Cloud Security?
Cloud security encompasses the technologies, policies, and practices that protect cloud-based infrastructure, applications, and data. As organizations move workloads to AWS, Azure, Google Cloud, and adopt SaaS applications like Microsoft 365 and Salesforce, traditional security approaches must adapt.
The cloud isn’t inherently insecure, but it requires different security thinking. Most cloud breaches result from customer misconfigurations—not failures by cloud providers.
The Shared Responsibility Model
Cloud security responsibilities are split between the provider and customer:
Cloud Provider Responsibilities
- Physical security of data centers
- Network infrastructure
- Hypervisor and virtualization
- Storage infrastructure
- Compliance of underlying platform
Your Responsibilities
- Identity and access management
- Data encryption and protection
- Configuration of cloud resources
- Application security
- Compliance of your implementation
This split varies by service type. In IaaS (virtual machines), you’re responsible for more. In SaaS (like Microsoft 365), the provider handles more—but you’re still responsible for access controls, data protection, and proper usage.

Cloud Security Challenges
Misconfiguration
The #1 cause of cloud breaches:
- Storage buckets left publicly accessible
- Overly permissive IAM policies
- Default credentials not changed
- Security groups too open
Shadow IT
Users adopting cloud services without IT approval:
- Sensitive data in unauthorized apps
- No visibility or control
- Compliance violations
- Data loss risk
Identity Sprawl
Too many accounts with too much access:
- Former employees with active accounts
- Excessive permissions
- Shared credentials
- Service account proliferation
Data Protection
Information scattered across cloud services:
- Where is sensitive data?
- Who can access it?
- Is it encrypted?
- Can it be recovered?
Key Features
Cloud Security Posture Management Featured
Continuous monitoring of cloud configuration against security best practices.
Show details Hide details
CSPM tools scan your cloud environments for misconfigurations, excessive permissions, and compliance violations. Fix issues before attackers find them.
Identity & Access Management
Control who can access what in your cloud environment.
Show details Hide details
Implement least privilege access, enforce MFA, manage service accounts, and audit access regularly. Zero trust principles applied to cloud access.
Data Loss Prevention
Prevent sensitive data from leaving your control.
Show details Hide details
Monitor and block sensitive data sharing via cloud applications. Prevent accidental or intentional data exfiltration through email, sharing, and downloads.
Cloud Backup & Recovery
Protect cloud data from deletion, corruption, and ransomware.
Show details Hide details
Cloud providers don't backup your data the way you think. Third-party backup for Microsoft 365, Google Workspace, and SaaS applications protects against data loss.
Security Monitoring
Detect threats across cloud environments.
Show details Hide details
Aggregate logs from cloud platforms, detect suspicious activity, and respond to incidents. Cloud-aware SIEM and SOC services.
Compliance Automation
Maintain compliance with automated controls and reporting.
Show details Hide details
Continuous compliance monitoring against HIPAA, SOC 2, PCI DSS, and other frameworks. Evidence collection and audit support.

Frequently Asked Questions
Isn't the cloud already secure?
Cloud providers secure their infrastructure, but security is a shared responsibility. You're responsible for your configurations, access controls, and data. Misconfiguration is the #1 cause of cloud breaches.
What's the shared responsibility model?
Cloud providers secure the underlying infrastructure (physical security, hypervisors, network). You secure everything you put on top: configurations, access controls, data, applications, and operating systems. The exact split varies by service type (IaaS vs PaaS vs SaaS).
Does Microsoft 365 backup my data?
No—not the way you'd expect. Microsoft provides high availability (your data is replicated) but not point-in-time recovery. If data is deleted (accidentally or by ransomware), recovery is limited. Third-party backup is essential for Microsoft 365, Google Workspace, and other SaaS platforms.
What are common cloud misconfigurations?
Publicly accessible storage buckets, overly permissive access policies, unencrypted data, missing MFA, default settings, and exposed APIs. These misconfigurations are responsible for most cloud breaches.
How do you monitor cloud environments?
Cloud providers offer native monitoring and logging (AWS CloudTrail, Azure Monitor, etc.). We aggregate these logs with SIEM tools, create detection rules for suspicious activity, and provide 24/7 monitoring with incident response.
What about compliance in the cloud?
Cloud can actually make compliance easier with the right approach. Automated compliance monitoring tools check configurations against regulatory requirements continuously. We help design compliant architectures and maintain evidence for audits.
