In many enterprises’ data security construction, the focus often falls on network perimeter defense, endpoint antivirus, or database security, while overlooking an equally critical risk source—the documents themselves. In particular, core documents such as source code, design blueprints, and technical proposals, once leaked, often mean the loss of core competitiveness.
As a result, many enterprises choose to deploy encryption software, hoping that “encryption” will provide a one-time solution. In practice, however, single-point encryption usually only addresses the issue of “encrypting files on disk,” but cannot cope with risks such as insider deliberate disclosure, file exfiltration after decryption, photographing and screenshotting, or out‑of‑control endpoint environments. Once an encrypted file is opened by a legitimate process, it can be leaked via copying, saving as, uploading, email, instant messaging, and other channels.
So, without affecting R&D efficiency and employees’ normal office experience, how can enterprises build a truly effective document anti‑leakage system? Let’s start with a typical R&D scenario.
Scenario: Source code leakage risk at a software company
In a medium‑sized software enterprise, the R&D center has hundreds of developers, with source code scattered across endpoints, SVN/Git servers, and test environments. The company had already deployed some encryption software, but a security audit still uncovered:
- A departing employee sent source code of multiple projects to their personal account via instant messaging tools in batches before leaving;
- Some employees uploaded code to personal GitHub repositories for remote work;
- Outsourcing staff copied code via USB drives;
- Some endpoints had unauthorized remote control software installed, posing risks of data exfiltration.
Further investigation revealed that the problem was not that encryption itself failed, but rather a lack of integration with endpoint behavior, outbound channels, permission policies, and audit trails. The encryption software only protected files at rest, but failed to control the flow and outbound transmission of files “in use.”
Subsequently, the enterprise introduced the Ping64 Integrated Office Security Platform to systematically govern source code and core documents.
How Ping64 builds a document anti‑leakage system with encryption at its core
Ping64 does not simply encrypt documents; instead, it manages the entire lifecycle of documents—from creation, usage, storage, and outbound distribution to destruction—around four core objectives: encryption, control, auditing, and traceability. Its core logic is: using transparent encryption as the foundation, endpoint control as support, and outbound control plus audit traceability as a closed‑loop to form integrated protection.
1. Transparent encryption without changing usage habits, making security “invisible” in practice
Ping64 employs driver‑level transparent encryption technology to automatically encrypt source code, design documents, Office files, and more. Employees can open, edit, compile, and debug files normally on authorized endpoints, with files being automatically decrypted; once they leave the controlled environment, files remain in ciphertext.
The entire process requires no manual encryption/decryption and does not change the usage habits of development tools or office software. At the same time, Ping64 supports process identification for mainstream development tools, IDEs, compilers, and version management tools, ensuring deep compatibility between encryption and R&D workflows and avoiding compilation failures, debugging anomalies, or version conflicts caused by encryption.
2. Process‑level access control to prevent “legitimate tools” from becoming leakage channels
A common oversight in single‑point encryption is that after encrypted files are opened by legitimate processes such as Word or an IDE, they can be leaked via “Save As,” “copy‑paste,” uploading, etc. Ping64 uses process whitelisting and access controls to restrict access to encrypted files only to authorized processes, while implementing fine‑grained control over clipboard operations, drag‑and‑drop, printing, and screenshotting.
Even when a file is opened, it cannot be freely copied to uncontrolled applications or external storage. For example, employees can view code normally in the IDE, but cannot paste code content into personal chat windows or upload it to unauthorized web pages.
3. Unified control over outbound channels, ensuring files are “controllable, traceable, and recoverable” when leaving
In actual business, enterprises cannot completely prohibit file outbound transmission—for instance, when sending proposals to clients or collaborating with outsourced teams. Ping64 provides approval and permission control for outbound files, supporting settings such as open passwords, validity periods, open counts, read‑only, print prohibition, copy prohibition, and other permissions.
All outbound actions must go through approval, and the system automatically records the content, recipients, time, and permissions, ensuring that files remain controlled even outside the enterprise. For high‑risk outbound actions—such as uploading to personal cloud drives, sending to personal email, or transferring files via IM—the system can block them in real time or raise alerts, keeping file outflows visible and controllable at all times.
4. Combining screen watermarking and document watermarking to make leakage behavior impossible to hide
For leakage methods that are technically difficult to block, such as photographing and screenshotting, Ping64 provides screen watermarking and document watermarking capabilities. Dynamic watermarks containing employee information, timestamp, and device identifiers can be displayed on endpoint screens; documents sent out or printed can carry implicit watermarks.
In the event of a leakage, the source can be quickly traced through watermark information, creating a strong psychological deterrent and post‑event traceability. For source code files, Ping64 also supports embedding watermark information in exported code files, facilitating溯源 when leaks are discovered in open‑source communities or external environments.
5. Behavioral auditing and intelligent analytics: from “post‑event accountability” to “pre‑event warning”
Ping64 not only logs file operations but also pays attention to the integrity of the behavior chain. The system comprehensively audits file creation, modification, copying, renaming, deletion, outbound transmission, printing, uploading, and more, while combining endpoint behavior analysis to identify abnormal operation patterns.
For example, if an employee accesses a large number of source code files not related to their own projects in a short period, frequently sends files out, or exports large batches of documents outside working hours, the system can automatically trigger alerts, allowing the security team to intervene before a leak occurs. This shift from “post‑event accountability” to “pre‑event warning” is a capability difficult to achieve with single‑point encryption products.
6. Integration with endpoint security capabilities to close loopholes beyond encryption
Document leaks are often directly related to uncontrolled endpoint environments. The Ping64 Integrated Office Security Platform includes endpoint O&M, software management, peripheral control, patch management, remote assistance, and other capabilities, which can be integrated with encryption policies.
For example, when an endpoint contains unauthorized software, lacks security patches, or has illegal peripherals connected, the system can automatically tighten access permissions for encrypted files, reducing leakage risks. This “encryption + endpoint” integration ensures that document security is no longer an isolated encryption layer, but deeply coordinated with endpoint environments and employee behaviors.
7. Comprehensive advantages of an integrated platform: not a pile‑up of multiple tools, but policy synergy
Many enterprises, in an attempt to compensate for the shortcomings of single‑point encryption, purchase multiple systems such as DLP, desktop management, auditing, and watermarking—but the systems lack data interoperability and policy synergy, leading to high operational costs. The Ping64 Integrated Office Security Platform unifies encryption, endpoint control, outbound management, audit trail, watermarking, and traceability into a single platform, enabling unified policy orchestration, unified data aggregation, and unified risk presentation.
Administrators can complete the entire workflow—from policy deployment, event viewing, risk handling, to report output—from a single console, significantly reducing management complexity. For R&D‑oriented enterprises, this means the security team can accomplish full‑lifecycle protection of source code and core documents without switching between multiple systems.
From “single‑point encryption” to “integrated protection”
The implementation of Ping64 moves enterprise source code and core documents from “static encryption” to “full‑lifecycle control.” Encryption is no longer an isolated layer of protection, but deeply coordinated with endpoint environments, employee behaviors, outbound channels, and audit trails.
More importantly, this protection system does not come at the cost of R&D efficiency: transparent encryption runs invisibly, approval processes are clear and efficient, compliant outbound transmissions are smooth and traceable, and employees’ normal development and collaboration remain unaffected. Through the Ping64 Integrated Office Security Platform, enterprises can achieve comprehensive visibility, control, auditability, and traceability over documents without changing existing business systems and development workflows—making encryption a true core foundation for data leakage prevention, rather than the only line of defense.
Enterprise document leakage prevention cannot rely solely on single‑point encryption. The Ping64 Integrated Office Security Platform, with encryption at its core, integrates endpoint control, outbound management, behavioral auditing, and watermark traceability to help enterprises build a defense‑in‑depth system—from source to outbound, from internal to external—comprehensively strengthening the data protection barrier.
