Imagine this scenario: a financial institution migrates a portion of its customer data to cloud storage, while keeping critical business processes on local servers. A few weeks later, auditors discover that sales department employees, using cloud collaboration tools, accidentally downloaded confidential client lists to their personal devices. This scenario, unfortunately, is not uncommon and highlights a key problem: traditional data protection mechanisms often struggle to cope with the dynamics of hybrid infrastructures, where information freely moves between on-premise and cloud environments.
Challenges of data protection in hybrid infrastructure
Hybrid infrastructure, combining local resources and cloud services (IaaS/PaaS/SaaS), offers companies flexibility and scalability. However, it also creates a complex environment for ensuring data security. Key challenges include:
- Diverse leakage points: data can leak through corporate networks, cloud storage, email, messengers, mobile devices, and other channels.
- Monitoring complexity: tracking data flows between on-premise and cloud resources requires integrated solutions that can see the entire picture.
- Lack of a unified security policy: data protection policies designed for on-premise infrastructure often do not automatically apply to cloud environments, leading to security gaps.
- Shadow IT: employees using unauthorized cloud services for data exchange creates uncontrolled leakage channels.
The role of DLP solutions in a hybrid environment
DLP (Data Loss Prevention) systems are a critical component of a data protection strategy in hybrid infrastructure. Their primary task is to detect, monitor, and prevent the unauthorized movement, use, or access of confidential information. In the context of hybrid solutions, DLP must:
- Provide unified control: apply the same security policies to data regardless of its location – on local servers or in the cloud.
- Integrate with cloud services: be able to analyze traffic and content in popular SaaS applications (Microsoft 365, Google Workspace, Box, Dropbox, etc.).
- Monitor endpoints: control user actions on workstations and mobile devices, preventing leaks through USB drives, printing, or copying.
- Utilize contextual analysis: not just search for keywords, but understand the context of data, its classification, and sensitivity level.
DLP architecture for hybrid infrastructure
An effective DLP system for a hybrid environment typically includes several components working in synergy:
| DLP Component | Functionality | Scope of Application |
|---|---|---|
| Endpoint DLP | Control actions on workstations: USB, printing, clipboard, screenshots. | On-premise and remote workstations |
| Network DLP | Monitoring network traffic: email, web requests, file transfers. | Corporate network perimeter, cloud gateways |
| Cloud DLP (CASB integration) | Analyzing data in cloud applications (SaaS), controlling access and sharing. | Cloud services, PaaS/IaaS |
| Storage DLP | Scanning data storage (file servers, databases) for confidential information. | On-premise and cloud storage |
Centralized policy management is key, allowing administrators to configure and enforce rules for all system components, ensuring consistent protection.
How Softline solves this
The Softline team understands the complexity of data protection in modern hybrid environments and offers comprehensive solutions for implementing and integrating DLP systems. We help clients develop an effective Data Loss Prevention strategy that considers the specifics of their infrastructure and business processes.
- Audit and consulting: Softline specialists conduct a deep analysis of the current infrastructure, identify sensitive data and potential leakage points, and develop customized security policies and compliance with legislation (e.g., personal data protection).
- Implementation and integration: we implement leading DLP solutions, adapting them to the client’s hybrid architecture. This includes integration with existing cloud solutions (SaaS, IaaS) and on-premise systems, such as ERP/CRM or Megapolis.Documentflow electronic document management systems, to ensure comprehensive control.
- Configuration and optimization: the Softline team configures DLP rules and policies for effective detection and prevention of leaks, while minimizing false positives. We also train client personnel on system operation and incident response.
- Development on UnityBase: when standard solutions do not cover unique client needs, Softline can develop custom modules or integration solutions on the UnityBase platform, providing advanced control and automation of data protection processes.
Effective data protection in a hybrid infrastructure requires more than just installing a DLP system; it demands a comprehensive approach including meticulous planning, adaptation of security policies, and continuous monitoring. Companies must recognize that security perimeter boundaries are blurring, and only integrated solutions capable of controlling data flows across all environments can provide the necessary level of protection for confidential information.
In hybrid infrastructures, unifying DLP policies becomes critical. We recommend integrating cloud DLP services with existing on-premise solutions, ensuring a single monitoring and control center for all data, regardless of its location. This helps avoid 'blind spots' and guarantees compliance with regulatory requirements.
