Organizations invest heavily in preventing sensitive information from leaving controlled systems through DLP tools, access controls, logging systems, secure viewers, and monitoring infrastructure.
But once information is rendered on a screen, those protections no longer work.
A screenshot, phone photo, or printed copy can bypass traditional controls while still exposing sensitive information externally. Organizations are often left with evidence that a leak occurred but no reliable way to determine where it came from.
This challenge is especially common in environments where employees, contractors, partners, or vendors legitimately access sensitive operational systems as part of their normal work.
For example, an employee may photograph an internal dashboard or operational system using a personal phone and share the image externally. Security teams may then have evidence that sensitive information was exposed but no reliable way to determine which system or individual the leak originated from.
EchoMark Screen is designed to address this problem.
What is EchoMark Screen?
EchoMark Screen applies watermarking directly to rendered screen output on managed devices.
If sensitive information is later exposed through a screenshot, phone photo, or similar artifact, the artifact can be uploaded into EchoMark’s investigation workflow to support attribution back to the originating device and time window.
The platform works as part of EchoMark’s broader attribution platform rather than as an isolated overlay or standalone SDK.
The system combines:
- Invisible watermarking for forensic attribution
- Visible watermarking for deterrence and accountability
- Integrated investigation workflows through EchoMark’s proprietary detection experience
Together, these capabilities are intended to help organizations move from inconclusive investigations toward operationally actionable attribution.
Why existing approaches struggle with screen-based leaks
Most traditional security controls focus on controlling access to information or monitoring how information moves through systems.
These approaches remain important, but they become less effective once sensitive information is visible on a screen.
For example:
- DLP tools can monitor file movement but cannot reliably stop someone from photographing a screen with a personal device
- Access controls can restrict who can view information but cannot determine who later leaked it
- Log analysis can show who accessed a system, but personal devices and large numbers of legitimate viewers often make investigations inconclusive
- Traditional investigations frequently depend on interviews, timelines, and circumstantial evidence rather than content-level attribution
The system addresses this operational gap by embedding attribution context into the rendered content itself.
Designed for controlled deployment environments
EchoMark Screen is intentionally designed for managed environments, starting with Windows devices, where deployment, device ownership, and operational conditions are relatively controlled.
Examples include:
- Retail store systems
- Branch office environments
- Shared operational terminals
- Government or enterprise-managed workstations
This controlled deployment model allows organizations to evaluate screen-based attribution while minimizing operational variability during early deployment.
Visible and invisible watermarking work together
EchoMark Screen combines visible and invisible watermarking into a unified operational model.
Invisible watermarking supports forensic attribution while remaining non-visible during normal usage.
Visible watermarking provides a human-visible deterrence layer designed to reinforce accountability and discourage risky behavior before a leak occurs.
Depending on organizational configuration, visible watermarking may include:
- Static deterrence text
- Identity-based overlays
- Device-linked contextual identifiers
These visible overlays are intended to balance deterrence with usability rather than disrupt normal workflows.
Together, the visible and invisible layers are designed to support both behavioral deterrence and post-incident attribution.
Integrated investigations instead of isolated signals
The platform integrates directly into EchoMark’s broader investigation workflows.
When a leaked artifact is identified, investigators can upload the artifact into EchoMark's detection experience to evaluate attribution results alongside broader investigation context.
This unified approach is important because screen-based leaks rarely exist in isolation. Organizations often investigate a combination of:
- Documents
- Screenshots
- Phone photos
- Emails
- Printed materials
Organizations can investigate these different exposure paths through a common operational workflow.
Operational trust matters as much as attribution
Attribution results are only meaningful if organizations can also understand whether watermarking was operationally active at the relevant time.
For this reason, EchoMark Screen also introduces operational coverage awareness through protection states and coverage integrity monitoring via tools like Microsoft Intune and SCCM.
This allows organizations to interpret attribution results within the operational context of whether watermarking was functioning as expected during the relevant time window.
Why this matters operationally
The goal of EchoMark Screen is not simply to apply watermarking to screens.
The goal is to reduce investigation ambiguity and help organizations move from uncertainty toward operationally actionable attribution.
By combining deterrence, attribution, operational coverage awareness, and integrated investigations, EchoMark Screen is designed to help organizations investigate screen-based leaks with greater speed and confidence.
How EchoMark Screen Works
EchoMark Screen operates at the point where information becomes visible
EchoMark Screen focuses on the moment information is rendered and becomes visible on a screen. Some sensitive information is primarily distributed and protected as documents, emails, images, or other individually attributable content. Other sensitive information is primarily consumed visually within operational systems, dashboards, browser-based applications, remote sessions, or legacy tools where information is viewed directly on-screen.
Once sensitive information is displayed, it can potentially be captured through screenshots, phone photos, printed copies, or external recording devices.
EchoMark Screen is designed to preserve attribution context at the point where information is viewed.
Watermarking is applied during screen rendering
EchoMark Screen applies watermarking directly to rendered screen output on managed devices because sensitive information often appears across many different applications and systems.
EchoMark Screen is intended to strengthen broader attribution and information protection strategies rather than replace them. When some of the internal or legacy applications cannot be natively watermarked, EchoMark Screen closes the gap by adding a layer of attribution and detection at the point where information becomes visible.
Visible and invisible watermarking serve different purposes
EchoMark Screen combines visible and invisible watermarking into a unified operational model.
Visible watermarking provides a human-visible deterrence layer designed to reinforce accountability and discourage risky behavior before a leak occurs. Depending on organizational configuration, visible watermarking may include static deterrence text, identity-based overlays, or device-linked contextual identifiers.
Invisible watermarking supports forensic attribution while remaining non-visible during normal usage. Rather than relying solely on visible overlays or metadata, invisible watermarking is designed to persist as part of the rendered content itself.
Attribution is anchored to device identity and time window
EchoMark Screen is designed around the most commonly available baseline attribution model.
At minimum, attribution is associated with:
- Device identity
- Time window
This approach is especially important in operational environments where multiple users may share the same endpoint over time. When reliable user context is available, user attribution may also be included as part of the investigation context.
Conceptually, attribution results are designed to provide investigators with device attribution and time-window attribution as a deterministic baseline, with user and operational coverage context included when available.
This model allows organizations to maintain consistent attribution even in environments where devices are shared, user sessions change frequently, or operational workflows involve multiple personnel.
For example, a retail or bank workstation may be used across multiple shifts by temporary employees sharing the same operational login. In that scenario, device identity and time-window attribution still provide meaningful investigation context even if individual user attribution is incomplete or inconsistent.
The system is intentionally designed so that baseline attribution does not depend entirely on user identity being continuously available.
EchoMark Screen is designed as an operational attribution system
EchoMark Screen is not designed as a standalone overlay utility or isolated watermarking feature.
The system combines:
- Runtime watermarking
- Deterministic attribution context
- Coverage integrity awareness
- Endpoint operational modeling
- Integrated investigations
Together, these capabilities are designed to help organizations reduce investigation ambiguity and improve operational trust when screen-based leaks occur.
EchoMark Screen is intended to strengthen layered attribution across the broader EchoMark platform rather than replace existing watermarking or investigation capabilities.
Together, multiple attribution vectors can help organizations improve investigation confidence and operational trust across different types of leaked information.

This data is not use to train EchoMark's general investigation models.
Deployment & Pilots
What does a typical pilot deployment look like?
Most organizations begin with a limited deployment across a controlled device group and a small number of operational environments.
Initial pilots are typically focused on validating attribution reliability, operational feasibility, and investigation workflows.
What level of IT involvement is required?
Pilot deployments typically involve endpoint management, security, and operational stakeholders.
EchoMark team will need some understanding of the company's software distribution mechanism if the pilot is needed to be distributed via the company's software distribution mechanisms like Microsoft SCCM or Microsoft Intune.
How operationally disruptive is a pilot deployment?
Most pilot evaluations focus on a few devices in a controlled environment. During the first deployment of the client agent, these limited devices will see a visible EchoMark Screen overlay when the client-side agent starts. Over the phase of the pilot, EchoMark team will work with the pilot team members to tune the visibility of EchoMark Screen overlay to balance professionalism and detectability for the customer's specific use cases and device configurations.
How should organizations evaluate pilot success?
Organizations typically evaluate attribution reliability, attribution and investigation against existing threat vectors, investigation usability, and overall operational confidence.
How difficult is rollback or pilot removal?
In limited number of manual device deployments, the device admins can simply remove the screen marking client agent by uninstalling it. If the deployment for the pilot is has been done via Intune or SCCM, those distribution mechanisms can also be used to remove the client-side software from the pilot devices.
Does EchoMark Screen require changes to existing applications?
No. EchoMark Screen is a separate client-side agent that is installed on all devices that require screen marking.
Does EchoMark Screen affect device performance?
EchoMark Screen has minimal effect on the device performance - typically <1%.
Can organizations operate EchoMark Screen in regulated or isolated environments?
