CSPM vs SSPM: What’s the Difference?
CSPM (Cloud Security Posture Management) monitors and secures your cloud infrastructure — the AWS, Azure, and GCP accounts where you build and run applications. SSPM (SaaS Security Posture Management) monitors and secures your SaaS applications — the Salesforce, Microsoft 365, Slack, GitHub, and Okta environments where your teams collaborate and store data.
Both are posture management tools. Both scan configurations against security policies. But they operate on entirely different attack surfaces.
- CSPM answers: “Are my cloud infrastructure configurations secure?”
- SSPM answers: “Are my SaaS application configurations secure?”
If your organisation uses both IaaS/PaaS (cloud infrastructure) and SaaS applications — which virtually every organisation does in 2026 — understanding the boundary between CSPM and SSPM helps you avoid coverage gaps.
What is CSPM?
Cloud Security Posture Management continuously monitors cloud infrastructure for misconfigurations, compliance violations, and security risks.
CSPM Scope:
- Cloud providers: AWS, Azure, GCP, OCI, DigitalOcean
- Resources monitored: Compute instances, storage buckets, databases, IAM policies, security groups, VPCs, Kubernetes clusters, serverless functions, load balancers
- Threats detected: Public exposure, overly permissive IAM, missing encryption, configuration drift, compliance violations
- Compliance frameworks: SOC 2, ISO 27001, HIPAA, PCI-DSS, NIST, CIS Benchmarks, GDPR, DPDPA
CSPM Example Findings:
- An S3 bucket has public read access enabled
- A security group allows SSH from 0.0.0.0/0
- An RDS database does not have encryption at rest
- An IAM user has not rotated access keys in 180 days
- A Kubernetes pod is running as root
What is SSPM?
SaaS Security Posture Management continuously monitors the configurations and permissions of SaaS applications for security risks, excessive access, and compliance violations.
SSPM Scope:
- SaaS applications: Microsoft 365, Google Workspace, Salesforce, Slack, Zoom, GitHub, Okta, ServiceNow, Jira, Confluence, Dropbox, Box, Zendesk
- Configurations monitored: Authentication settings, sharing policies, API integrations, data exposure settings, user permissions, third-party app connections, file sharing rules
- Threats detected: OAuth app over-permission, public file shares, disabled MFA, stale admin accounts, excessive external sharing, insecure API tokens
- Compliance frameworks: SOC 2 (access controls), GDPR (data sharing), HIPAA (PHI access), ISO 27001 (access management)
SSPM Example Findings:
- External file sharing is enabled globally in Google Workspace
- A Salesforce admin account does not have MFA enforced
- An OAuth app connected to Slack has read access to all channels
- A former employee’s GitHub access token is still active
- Microsoft 365 allows users to consent to third-party apps without admin approval
Side-by-Side Comparison
| Dimension | CSPM | SSPM |
|---|---|---|
| What it monitors | Cloud infrastructure (IaaS/PaaS) | SaaS applications |
| Attack surface | AWS, Azure, GCP account configurations | Salesforce, M365, Slack, GitHub configurations |
| Primary risk | Misconfigurations leading to data exposure or breach | Excessive permissions and data over-sharing in SaaS |
| Detection method | API scanning of cloud provider configurations | API scanning of SaaS application settings |
| Identity focus | IAM roles, policies, and permissions in cloud | User accounts, OAuth apps, and sharing permissions in SaaS |
| Data risk | Publicly exposed storage, unencrypted databases | Publicly shared files, over-permissioned third-party apps |
| Deployment | Connects to cloud provider APIs | Connects to SaaS application APIs |
| Typical team owner | Cloud security / DevSecOps / Platform team | IT security / Identity team / GRC |
| Example vendor | Cloudanix, Wiz, Palo Alto | AppOmni, Obsidian, Adaptive Shield |
Why the Distinction Matters
Different Attack Surfaces
Cloud infrastructure and SaaS applications present fundamentally different security challenges:
Cloud infrastructure risks centre on misconfiguration of compute, storage, and networking resources. An attacker exploiting a cloud misconfiguration typically gains access to the infrastructure layer — compromising servers, databases, and internal networks.
SaaS risks centre on data access and sharing. An attacker exploiting SaaS misconfigurations typically gains access to business data — documents, customer records, communications, and source code — without ever touching cloud infrastructure.
Different Teams Own Them
In most organisations:
- Cloud infrastructure is owned by engineering, DevOps, or platform teams. They deploy the infrastructure, configure IAM, and manage security groups.
- SaaS applications are owned by IT, business teams, or individual departments. A marketing team configures Salesforce. HR configures Workday. Engineering configures GitHub.
This ownership split means a single security tool rarely covers both surfaces effectively.
Different Compliance Evidence
Auditors evaluate cloud infrastructure and SaaS applications as different control domains:
- SOC 2 CC6.1 (Logical Access) requires evidence from both cloud IAM and SaaS access controls
- HIPAA Security Rule covers both infrastructure hosting PHI and SaaS applications processing PHI
- GDPR Article 32 applies to both data stored in cloud databases and data shared via SaaS tools
A comprehensive compliance posture requires visibility into both.
When Do You Need CSPM?
CSPM is essential when your organisation:
- Builds and deploys applications on cloud infrastructure (AWS, Azure, GCP)
- Manages cloud resources — compute, storage, databases, Kubernetes clusters
- Has compliance requirements that cover infrastructure security controls
- Needs to prevent misconfigurations that lead to data breaches
- Operates multi-cloud environments where configuration consistency matters
Every organisation running cloud infrastructure needs CSPM. It is the baseline for cloud security hygiene.
When Do You Need SSPM?
SSPM becomes essential when your organisation:
- Relies heavily on SaaS applications for business operations (Microsoft 365, Salesforce, Slack)
- Has experienced incidents related to SaaS over-sharing or OAuth app compromise
- Needs to audit third-party application connections and their permissions
- Has compliance requirements covering data access in SaaS (GDPR data sharing, HIPAA PHI access)
- Manages a large number of SaaS users with varying permission levels
- Is concerned about shadow IT — unapproved SaaS applications connected via OAuth
When Do You Need Both?
Most mid-market and enterprise organisations need both CSPM and SSPM because they operate both cloud infrastructure and SaaS applications. The question is prioritisation:
Prioritise CSPM first if:
- Your primary workloads run on cloud infrastructure you manage
- Your highest-risk data lives in cloud databases and storage
- Infrastructure misconfigurations are your most likely breach vector
- Your team owns the cloud accounts and deploys infrastructure
Prioritise SSPM first if:
- Your organisation is SaaS-heavy with minimal custom cloud infrastructure
- Your highest-risk data lives in SaaS applications (Salesforce CRM data, Google Workspace documents)
- Third-party app permissions and OAuth sprawl are your primary concerns
- Shadow IT and unapproved SaaS connections are a known problem
Deploy both simultaneously if:
- You operate at scale with both significant cloud infrastructure and SaaS usage
- Compliance requirements cover both domains explicitly
- You have experienced incidents on both surfaces
How CSPM and SSPM Complement Each Other
In a mature security programme, CSPM and SSPM provide different views of a connected risk picture:
Identity Correlation
A user with excessive permissions in both cloud IAM (detected by CSPM) and SaaS applications (detected by SSPM) represents a higher-risk identity than either finding alone. Organisations with mature programmes correlate these signals.
Data Flow Visibility
Data often moves between cloud infrastructure and SaaS applications. CSPM monitors the storage and compute where data originates. SSPM monitors the SaaS tools where data is shared and consumed. Together, they provide visibility into data flow across both surfaces.
Compliance Coverage
A unified compliance posture requires evidence from both layers. SOC 2 auditors will ask about both cloud infrastructure controls and SaaS access management. Having both CSPM and SSPM evidence simplifies audit preparation.
