In today's collaborative digital environment, organizations face a significant challenge: enabling productive information sharing while preventing sensitive data from leaving secure boundaries. Files and documents contain your organization's most valuable information—intellectual property, financial data, customer records, and strategic plans. eScan's File Attachment Block feature provides granular, policy-driven control over how these critical assets move beyond your organization's boundaries, preventing data leakage while maintaining business workflows.
eScan's File Attachment Block is an advanced Data Loss Prevention (DLP) capability that lets you selectively control the flow of files from within your organization to external destinations. Unlike all-or-nothing approaches that either block everything or nothing, this feature provides process-specific, content-aware control over what files can be shared, with whom, and through which channels.
The technology works by intercepting file transfers at the application and network levels, evaluating them against your defined policies, and allowing or blocking the transfer based on multiple factors including file type, destination, content sensitivity, and user context. This precision control allows organizations to enforce consistent data handling practices without impeding legitimate business communication.
What truly sets eScan's approach apart is the ability to create exceptions for trusted domains and destinations, ensuring that legitimate business partners and workflows remain unaffected while still protecting against accidental or malicious data exposure.
The system identifies and monitors specific processes and applications commonly used to transfer files outside organizational boundaries, including:
• Email clients and webmail interfaces
• Cloud storage synchronization tools
• File sharing platforms and services
• Instant messaging and collaboration tools
• Web browsers and upload mechanisms
Administrators can define granular policies determining which types of file transfers should be permitted or blocked. These policies can be based on:
• File types and extensions
• Content classification and sensitivity levels
• Destination domains and services
• User groups and departments
• Time and location context
The solution allows organizations to define exception lists of trusted domains, subdomains, and services where file sharing should be permitted regardless of other policy restrictions. This ensures that legitimate business partners and approved services remain accessible while still protecting against unauthorized data transfers.
Beyond simply looking at file extensions, the system can examine file contents to identify sensitive information patterns including:
• Personally identifiable information (PII)
• Financial data and account numbers
• Intellectual property markers
• Confidential document classifications
• Custom data patterns specific to your organization
When a file transfer is attempted, the system evaluates it against configured policies in real-time, making an allow/block decision within milliseconds. Users receive immediate feedback about blocked transfers, including guidance on proper data handling procedures.
All file transfer attempts—both allowed and blocked—are thoroughly documented to provide complete visibility into information sharing activities across the organization. Detailed reports can be automatically generated and distributed to security teams and stakeholders.
The Growing Challenge of Data Exfiltration
In today's digital workplace, sensitive information can leave your organization through countless channels and in various formats. Recent industry analyses highlight the scope of this challenge:
The financial and operational impact of sensitive data exposure can be devastating:
While email attachments receive significant attention, modern data exfiltration often occurs through cloud services, collaboration platforms, and web applications—creating a complex security challenge that requires comprehensive yet flexible controls.
Unlike general-purpose DLP solutions that take a one-size-fits-all approach, eScan's File Attachment Block allows precise control over specific applications and processes. This granularity enables security teams to target high-risk sharing vectors while allowing legitimate business processes to continue unimpeded.
The ability to whitelist specific domains, subdomains, and services means that legitimate business partners are never impacted by security controls. This prevents the productivity impact and "shadow IT" that often results from overly broad blocking policies.
By focusing controls on specific high-risk processes and providing clear feedback when transfers are blocked, the solution minimizes user frustration while maintaining protection. This approach increases security policy compliance and reduces attempts to circumvent controls.
Beyond simple file type filtering, the system analyzes document content to identify sensitive information patterns, allowing for more intelligent and accurate control decisions based on actual data sensitivity rather than just file formats.
The detailed reporting capabilities provide security teams with complete visibility into file sharing activities across the organization, helping identify potential policy gaps and training opportunities while creating an invaluable audit trail.
The solution can adjust protection levels based on context, with different policies for different user groups, locations, and time periods. This adaptability ensures appropriate protection without unnecessary restrictions.
eScan's File Attachment Block integrates with existing security infrastructure including email gateways, web proxies, and endpoint security solutions, enhancing your security ecosystem rather than requiring wholesale replacement.
