DLP vs DSPM vs SSPM vs CASB: What Is the Difference and Which Do You Need?

• DSPM finds and classifies data. DLP blocks exfiltration based on that classification.
• SSPM checks the settings of the app itself. CASB checks the traffic to the app.
• Endpoint DLP covers part of the CASB job (cloud uploads).
• For most organizations the right order is: discover with DSPM, protect with DLP, fix cloud settings with SSPM.

Why are there so many acronyms?

Data no longer stays in one place. A customer list starts on a file server, lands on a laptop, goes out by email, is uploaded to OneDrive and is sometimes pasted into an AI tool. Each stop carries its own risk. The security market created a product category for each stop.

These categories are often mixed up during purchasing. One vendor says “DLP” but only looks at email. Another says “SSPM” but actually sells a CASB. This article shows which question each category answers.

Comparison in one table

DLP: Stop data from leaving

DLP (Data Loss Prevention) controls the exit of sensitive data with policies. Channels include USB drives, email attachments, cloud uploads, clipboard and printers. Policies look at content (national ID, IBAN, source code) or labels.

The weak point of DLP: it must know what to protect. If data is not classified, policies are either too broad and break work, or too narrow and miss leaks.

DSPM: Find the data first

DSPM (Data Security Posture Management) discovers where sensitive data lives. It scans file shares, endpoints and data stores, classifies each file and shows excessive access rights.

DSPM does not block exfiltration. Its job is to build the map. You use that map to write correct DLP policies and to validate your GDPR or KVKK data inventory.

SSPM: Check the settings of cloud apps

SSPM (SaaS Security Posture Management) checks SaaS configuration. Typical findings are public sharing links, weak authentication settings, extra admin accounts and risky OAuth grants.

SSPM does not look at traffic. It connects to the admin API of the app and reads settings. The CISA SCuBA project publishes secure configuration baselines of this kind for Microsoft 365 and Google Workspace.

CASB: Control traffic to the cloud

A CASB (Cloud Access Security Broker) sits between users and cloud services. Gartner defines it as a policy enforcement point between cloud consumers and providers. A CASB shows which apps are in use and restricts access or uploads to unapproved apps.

Today CASB is often sold as part of an SSE (Security Service Edge) suite. Check your current network security contract before you buy it as a separate product.

Where do they overlap?

• DLP and CASB: Both can block uploads to the cloud. Endpoint DLP does it on the device, CASB in the traffic.
• SSPM and CASB: Both see SaaS use. SSPM checks settings, CASB checks user activity.
• DSPM and DLP: DSPM classification feeds DLP policies. If one agent does both, the integration work disappears.

In what order should you deploy them?

Every organization has different priorities. For a mid-size company, the order below usually gives the fastest result.

• 1. Discover with DSPM: Find where personal and confidential data is. Validate your data inventory.
• 2. Protect with DLP: Turn on the riskiest channels (USB, personal cloud, AI tools) first in monitor mode, then in block mode.
• 3. Fix cloud settings with SSPM: Close public shares and risky OAuth grants in Microsoft 365 and Google Workspace.
• 4. Evaluate the need for a CASB: If endpoint DLP and SSPM close most gaps, you may not need a separate CASB.

How does Moftgate cover these categories?

Moftgate runs DLP and DSPM on the endpoint with the same agent. The SSPM module checks risky settings and OAuth grants in SaaS apps. Data and logs stay on your own servers. The first 200 endpoints are free for the first year, so you can start discovery at no cost.
