Cloud Data Security

Protect Sensitive Data Across Your Cloud Environment

Discover, classify, and secure sensitive data across cloud services and SaaS apps. Reduce exposure, govern access, and stop risky data movement with cloud data security that understands people, data, and risk.

Security operations team monitors data and system activity across multiple screens.

OVERVIEW

See and secure your cloud data wherever it goes

Sensitive data constantly moves across cloud services, SaaS apps, collaboration platforms, and AI tools. To protect that data, security teams need to know what data is sensitive, where it resides, who can access it, and how it's being used.

Effective cloud data security combines visibility and access controls to help organisations discover, protect, and govern sensitive data across their cloud environments.

Discover sensitive data

Find regulated, confidential, and business-critical data across cloud, SaaS, and hybrid environments.

Understand data exposure

Identify oversharing, excessive permissions, risky access, shadow data, and SaaS misconfigurations.

Apply adaptive controls

Enforce DLP policies, govern access, remove risky sharing, and respond based on user, data, and threat context.

CLOUD DATA RISK

Cloud data risk starts with people, data, and access

Your people collaborate across platforms, connect third-party apps, and increasingly use AI tools that interact with business data. This also brings countless new ways for sensitive data to be shared, accessed, and exposed. Without visibility into where that data resides, who can access it, and how it's moving, your team can't reduce exposure before it leads to data loss or a breach.

CLOUD DATA LIFECYCLE

Protect cloud data from discovery through remediation

Effective cloud data security is a continuous process, not a single control. Proofpoint helps security teams discover sensitive data, understand exposure, and remediate risk across cloud services, SaaS apps, and AI tools.

1. Discover

Find sensitive data across SaaS, cloud apps, collaboration platforms, and hybrid environments.

2. Classify

Identify regulated data and business-critical content with Smart Identifiers, templates, and AI-powered data classification.

3. Analyse access

See who can access sensitive data, how it is shared, and where excessive permissions create exposure.

4. Understand behaviour

Correlate file activity, user behaviour, insider risk signals, and compromised account indicators to identify risky data movement.

6. Remediate

Remove risky shares, reduce permissions, revoke OAuth access, and suspend active sessions before data loss occurs.

5. Enforce controls

Apply DLP policies to detect and contain risky data movement and govern access to sensitive data across SaaS apps.

AI DATA EXPOSURE

Find the sensitive data your AI tools can already reach

AI tools and agents you adopt inherit access to the data in your cloud and SaaS environments. If you lack visibility into that access, everyday AI use can quickly put sensitive data at risk.

Proofpoint Data Security Posture Management (DSPM) discovers and classifies sensitive data, then maps the users, apps, and AI agents that can access it. When it identifies exposure, DSPM closes the loop by governing access, remediating risk, and triggering DLP enforcement.

Sensitive Data Discovery

Find and classify sensitive data at scale, including business-specific content that traditional rules miss.

Data Access Governance

Map access to sensitive data across users, apps, and AI agents, and automatically remove risky permissions.

AI Data Exposure Visibility

Visualise the path from copilots, GenAI tools, and AI agents to the sensitive data they can reach.

Closed-Loop Remediation

Automatically turn findings into DLP policies and access remediation actions, with no manual translation.

SaaS and AI App Posture

Discover shadow apps and detect SaaS misconfigurations before they expose sensitive data.

CLOUD AND AI DLP

Detect and contain sensitive data shared with AI tools and cloud apps

Data moves through AI and cloud apps in ways that are difficult to track. Without consistent visibility and controls, risky sharing can quickly lead to data loss, noncompliance, or AI-driven exposure.

Proofpoint Cloud DLP monitors sensitive data across SaaS apps and AI tools, correlating content with user behaviour and risk signals to automatically contain exposure before it escalates.

Cloud and AI App Coverage

Monitor sensitive data across SaaS and sanctioned and unsanctioned AI tools with a single policy engine.

Behavioural Risk Detection

Correlate sensitive data with user behaviour and risk signals to identify accidental sharing, malicious exfiltration, and compromised accounts.

Oversharing Detection and Remediation

Identify files exposed through public links or excessive sharing, including organisation-specific content that traditional rules overlook.

Automated Response

Automatically quarantine files, revoke shared links, and suspend active sessions to contain exposure.

Frequently Asked Questions

Cloud data security protects sensitive data across cloud services, SaaS applications, AI tools, collaboration platforms, and cloud storage. It combines data discovery, data classification, identity and access management, and data loss prevention (DLP) to help organisations secure data wherever it is stored, shared, or moved. As organisations rely more on cloud services, data security for the cloud has become essential for protecting sensitive information while supporting compliance requirements.

Proofpoint helps organisations discover and classify sensitive data, govern access, monitor risky activity, and apply adaptive DLP policies across SaaS applications and AI tools. By connecting Data Security Posture Management (DSPM), Cloud DLP, and data access governance, Proofpoint helps reduce cloud data exposure before it leads to data loss or a data breach.

AI tools inherit the same permissions people already have across cloud services and SaaS applications. Proofpoint DSPM discovers and classifies sensitive data, then maps the users, applications, and AI agents that can access it, helping security teams identify AI-accessible data, reduce excessive permissions, and secure data before it is exposed.

Cloud DLP protects sensitive data while it is being shared or moved across cloud services, SaaS applications, and AI tools. DSPM discovers where sensitive data resides, who can access it, and where exposure creates risk. Together, they help organisations discover sensitive data, understand exposure, and apply consistent protection across cloud environments.

Yes. Cloud access security broker (CASB) capabilities help organisations discover shadow IT, govern SaaS usage, monitor cloud activity, and control third-party application access. As cloud environments have evolved, CASB has become one part of a broader cloud data security strategy that also includes DSPM, Cloud DLP, data access governance, and SaaS security posture management.

Cloud data security helps organisations identify regulated and sensitive customer data, monitor how it is used, and apply consistent security measures across cloud services and cloud storage. By improving data classification, governance, and data loss prevention, organisations can better support regulatory compliance requirements while reducing the risk of data exposure. A strong strategy for data protection in the cloud helps organisations apply consistent controls wherever sensitive data resides or moves.
