Key Features

Watermarking & Protection

Forensic Watermarking API

EchoMark's API enables enterprises to embed forensic watermarking into applications, internal tools, and custom workflows. This allows organizations to automate watermarking and leak detection at scale, ensuring sensitive information is protected without disrupting existing operations.

Visible & Invisible Watermarking

Implementing both visible and invisible watermarking provides organizations with a powerful layer of security and accountability for sensitive information. Visible watermarks deter unauthorized sharing, while invisible forensic watermarks maintain document aesthetics and provide traceability.

Automate Document Watermarking & Leak Detection

The EchoMark API allows users to upload original documents and generate individualized marked copies for recipients. This ensures that all private data is protected with forensic watermarking, enabling tracking and tracing of sensitive information.

Investigate Leaks with EchoMark

When a breach occurs, users can retrieve forensic results programmatically to investigate the leaked artifact and identify the source. The API facilitates document upload and marked-copy generation, while investigation and attribution occur within EchoMark.

SecureView for File Sharing

EchoMark SecureView provides a secure way to share sensitive information with real-time control and analytics. It prevents unwanted sharing and data exfiltration by adding an extra layer of security to every file shared, ensuring that only authorized recipients can access the information.

Personalized Views in SecureView

Each recipient can access a forensically watermarked view of each file, uniquely personalized for them. This ensures that sensitive information is clearly marked and traceable to specific individuals.

Conditional Downloads

SecureView allows users to set file permissions to control what happens to shared documents. This feature ensures that files remain in the right hands by enabling or disabling download options for recipients.

Document Analytics

SecureView provides insights on file views, shares, and recipient activity. This encourages data stewardship and helps users track how their sensitive information is being accessed and shared.

Leak Prevention & Remediation

Prevent Unauthorized Sharing

Individualized watermarks on important documents and communications inform recipients that the information is private and intended to remain confidential. This proactive measure helps deter leaks before they happen.

Remediate Leaks

If EchoMarked content is leaked, EchoMark's technology quickly identifies whose copy was exposed. This feature allows organizations to respond swiftly to data breaches and mitigate potential damage.

Chain of Custody

EchoMark ensures a clear chain of custody for private information as it is shared. This feature creates accountability among handlers of sensitive data and generates a clear path for remediation in the event of a leak.

Quick Source Identification

EchoMark's unique signatures embedded invisibly in sensitive communications enable quick identification of leak sources. This feature provides robust investigative reports that can be used as evidence for security teams.

Integration & Workflow

Seamless Integration with Existing Workflows

EchoMark's solutions integrate seamlessly with existing document management systems and email platforms like Microsoft Exchange and Google Workspace. This allows for automatic watermarking without disrupting familiar workflows.

Self-service API Access

Users can create API clients directly in the EchoMark web application without the need for manual approval. This self-service access simplifies the integration process for developers.
