Data Loss Prevention Strategies for Cloud-Based Companies 

There’s no denying the cloud offers major advantages. Scalability, cost savings, easy collaboration – the list goes on and on. However, it’s not all positive. It also creates new risks, especially when it comes to data loss.

Because of this, cloud-based companies must adopt a modern approach to data loss prevention. This guide explores effective prevention strategies that help organizations remain secure without compromising the benefits of the cloud.

Understand the New Data Perimeter 

Traditional IT environments typically see security teams rely on firewalls and on-premises tools to control data flow. In the cloud, however, the network perimeter is blurred. Data moves across multiple SaaS apps, devices, and regions. It can then be shared, copied, and downloaded in seconds, often outside the visibility of IT.

To craft a strong data loss prevention (DLP) program for the cloud, companies must start mapping the location, flow, and access of sensitive data. This includes stored data in:

• SaaS platforms
• Cloud storage services
• IaaS environments
• Collaboration apps

This mapping, and the visibility gained from it, is the foundation of any prevention strategy. Without it, businesses risk focusing protection on the wrong endpoints.

Classify and Prioritize Sensitive Data

Not all data requires the same level of protection. The next step is to identify the “sensitive” data your business stores and uses. This can include:

• Personally identifiable information
• Payment data
• Intellectual property
• Financial records and forecasts
• Confidential client or partner information

Modern DLP solutions support automatic classification. This can be done using metadata, keyword rules, and machine learning. In doing so, it assists in categorizing documents in real-time as they’re created and uploaded to cloud apps.

When you prioritize your most valuable data, it’s possible to apply stricter controls without overwhelming users or systems.

Implement Strong Access Controls 

Cloud platforms make sharing data simple. While this can be a strength, it’s also a liability. A strong DLP strategy will always include tight access controls. Doing this ensures only the right people can view and share certain information.

Key best practices include:

• Role-based access: Assign permissions based on job roles. As a result, employees only gain access to the data they require.
• Multi-factor authentication: Add a layer of identity verification to limit unauthorized access.
• Granular sharing policies: Restrict external sharing or downloading of documents which contain sensitive data.
• Session timeouts and device checks: Auto logout users and block access across unmanaged devices.

Improving access controls through these methods helps prevent data from ending up in the wrong hands.

Monitor Insider Threats and Human Error 

It’s easy to believe elite hackers are behind most data breaches, but this isn’t the case. They often happen because of internal mistakes. In 2024, 95% of data breaches were attributed to human error. An employee may accidentally send a file to the wrong recipient, for instance, or they could unwillingly use an insecure app. Cloud-based companies must take these threats seriously.

Behavioral monitoring tools are recommended for this reason. They can flag numerous anomalies, ranging from large file downloads to access from unknown locations. Indicators like these can be clear signs of misuse, negligence, and even malicious intent.

This is also where a Cloud Access Security Broker (CASB) plays an important supporting role. A CASB sits between users and cloud services, where it offers visibility and control across SaaS, PaaS, and IaaS platforms. Okay, they’re not full data loss prevention systems. Nevertheless, CASBs can:

• Detect and block risky data transfers
• Enforce policies based on user behavior and content
• Identify shadow IT and unsanctioned app use
• Integrate with DLP tools for more comprehensive enforcement

CASBs assist in closing visibility gaps in cloud ecosystems. They’re also especially useful for companies that incorporate multiple SaaS platforms.

Secure Data at All Stages

Yes, DLP is about putting a stop to data from leaking – but that’s not all. It is also about protecting data wherever it resides and travels. There are three main stages to consider:

1. At rest: Encrypt stored data in cloud environments and apply access controls at the file level.
2. In transit: Use TLS encryption for all data transfers between users, apps, and cloud services.
3. In use: Prevent screenshots, clipboard copying, and printing of sensitive data from browser-based apps.

Cloud-based DLP tools are evolving to address these stages. This is done with elements like API integrations and browser isolation, helping data stay protected across its full lifecycle.

Educate Employees on Data Handling

Even the best technology isn’t enough on its own. A successful DLP program demands a company-wide culture of security awareness. Think of it this way: employees are on the front lines. They’re the first – and last – defense against accidental data loss.

How do you train employees effectively? Key topics to cover include:

• Best practices for cloud file sharing and permissions.
• How to recognize and handle sensitive information.
• Dangers of using unauthorized apps and storage services.
• Phishing and social engineering awareness.

It’s wise to commit to short, recurring training sessions. Employees can quickly lose focus and overlook security needs, so regular refreshers help to keep information fresh in the mind.

Integration with Your Broader Security Stack

DLP isn’t a standalone solution. At least, it shouldn’t be on its own. For maximum effectiveness, it should integrate with your broader security stack. This security stack should include:

• Identity and access management systems
• CASBs and secure web gateways
• Endpoint detection and response platforms
• SIEM tools for centralized logging and incident response

Integration means your policies remain consistent across devices and apps. It also supports security teams in being able to respond more efficiently to incidents. For example, if a user triggers a DLP rule while also exhibiting suspicious login behavior, the system can automatically escalate the alert.

Conclusion

The rules of data security have been changed thanks to the cloud. It is essential for any company using this technology to invest in a proactive, adaptable DLP strategy. That’s where the above strategies can make the difference. With everything from classifying sensitive data to training employees, your company can reduce risk without losing the agility the cloud supplies.
