How Ping32 Prevents Theft of High-Net-Worthy Client Data in Finance

In an era where digital transformation and high-frequency trading have become industry norms, the trading data, core client information, proprietary algorithms, and pricing strategies held by securities firms, fund companies, futures institutions, and other financial organizations have risen to become their most valuable digital assets. At the same time, the financial industry is also a “heavy-hit area” for data compliance regulation, facing not only strict constraints under laws and regulations such as the Cybersecurity Law and the Data Security Law, but also constant dual pressure from internal personnel threats and external ransomware attacks.

In reality, data leakage incidents at securities firms often occur in daily office scenarios: a relationship manager sends high-net-worth client profiles to competitors via WeChat before resigning; a trader privately backs up core trading strategies to a cloud drive; or even an employee directly uses a mobile phone to photograph sensitive reports displayed on a computer screen and leaks them externally. For financial institutions, the real challenge of trading data leakage prevention (DLP) is not about whether there is “security awareness,” but about how to ensure that data security policies permeate every operational detail of employees’ daily work without blind spots.

Real Pain Points of Securities Trading Data Leakage in the Financial Industry

In the actual office environments of securities firms and financial institutions, traditional perimeter defenses have become ineffective at blocking data exfiltration. Data security governance generally faces the following core pain points:

• Difficulty controlling multi-channel outbound transfers, making post-leak tracing challenging: Financial practitioners frequently use instant messaging tools (WeChat, Enterprise WeChat, DingTalk, etc.), web portals, and email clients on a daily basis. When core internal assets flow out through these disparate channels, organizations often cannot determine who sent sensitive content, at what time, or through which method. Once a leakage incident occurs, there is a lack of full-lifecycle audit and forensic evidence.
• Departure periods become high-risk windows for data loss: Around the time of personnel transfers or resignations, the risks of high-value client data, research reports, and historical trading data being maliciously deleted, altered, or copied out via USB drives are particularly pronounced. Organizations lack a closed-loop mechanism for comprehensive control and dynamic auditing at the source.
• Novel leakage methods are hard to defend against: As anti-screenshot restrictions in instant messaging apps are bypassed, employees can directly use smartphones to photograph trade secrets or internal official documents displayed on computer screens. This form of “physical leakage” through paper or image channels has become the most troublesome gray area in the financial industry.
• Risks from mixed use of USB drives and other removable storage devices: USB drives are small and portable, making them a popular medium for high-frequency information transfer. However, the indiscriminate use of USB drives across departments and the unauthorized connection of personal USB drives can easily lead to ransomware spreading across the internal network, as well as lateral leakage of confidential data.

How Ping32 Builds a Closed-Loop Full-Scenario DLP Solution for the Financial Industry

Targeting the leakage risks specific to securities trading scenarios, the Ping32 Endpoint Security Management System, based on a strategy of “proactive discovery and comprehensive protection,” offers financial institutions a tailored, actionable one-stop data leakage prevention (DLP) solution.

The system uses sensitive content identification as its core engine, combined with multi-dimensional modules such as internet behavior auditing, document transparent encryption, removable storage control, and screen security. It shifts security control points forward to the moment business occurs, ensuring both smooth compliance pathways and precise interception of violations.

1.  Deep Application of Sensitive Content Identification for Precise Definition of Financial Digital Assets

The core value of financial institutions depends on data, and the prerequisite for data protection is a clear understanding of data distribution and attributes. Ping32 provides a powerful and flexible data classification rule library.

• Multi-dimensional rule matching: Administrators can use the Ping32 console to define feature signatures for high-risk files using combined conditions such as “keywords + regular expressions + frequency of occurrence.” For example, documents containing specific formats of “ID numbers,” “trading account numbers,” or “contract numbers,” and where terms like “order” or “quotation” appear more than three times, can be intelligently tagged as “confidential” financial or client information documents.
• Sensitive content scanning: Using the built-in sensitive content identification engine, the system can scan distributed text files, spreadsheets, PDFs, and more in real-time or on a scheduled basis. It classifies and labels static data, helping securities firms gain a comprehensive overview of the distribution of classified assets across the entire network.

2. Controlling Multi-Path Outbound Behaviors to Curb “Instant Messaging and Cloud Drive” Leakage

For the internet channels frequently used in daily office work, Ping32 provides deep, full-path file transfer control.

• Deep supervision of instant messaging: The system supports real-time recording and management of chat content and file transfers on major social software platforms like WeChat, Enterprise WeChat, DingTalk, and QQ. When the system detects an employee attempting to send a file containing high-net-worth client lists to an external party via WeChat, it can not only identify the sensitive content but also directly intercept the transfer based on configured policies.
• Web and cloud drive blocking: It accurately audits and blocks file transfers via cloud storage services such as Baidu Cloud and Tencent Weiyun. When an endpoint user’s outbound file transfer triggers specified rules (e.g., sending more than 20 sensitive files within 10 seconds), the system can automatically generate risk alerts, enable behavior tracing, and capture screen screenshots, leaving no place for malicious data transfers to hide.

3. Deploying Document Transparent Encryption for “Fortress-like” Data Flow Control

For areas involving core trading strategies, R&D code, or highly classified research reports, auditing outbound activities alone is insufficient; fundamental protection must be implemented at the source.

• Transparent encryption: Once Ping32’s document transparent encryption is enabled, files created or modified by employees through designated controlled programs (such as office software, IDE development tools, or reporting systems) will automatically trigger real-time, transparent encryption upon saving. Within the trusted corporate intranet environment, users can access and edit files normally without any impact. However, if a file is illegally taken out or copied outside the intranet, it will appear as garbled text.
• Security domains and classification isolation: Securities firms can set up file security zones (e.g., separate zones for Finance, R&D, and Marketing departments) and classification permissions for different functional departments, ensuring that users with lower clearance cannot open higher-classification documents and that encrypted files remain isolated across departments to prevent lateral data leakage within the enterprise.
• Compliant outbound processes: When data must be provided externally for business needs (e.g., delivering solutions to suppliers or partners), outbound packages can be created using Ping32’s file outbound process. These packages allow administrators to define usage permissions for recipients, such as prohibiting copying, editing, or printing, while also mandating anti-leak watermarks and automatic expiration, perfectly addressing secondary leakage risks when delivering financial data to third parties.

4. Implementing Robust Screen Security Management to Deter and Trace Mobile Phone Photography

To address the gray area that traditional DLP struggles to cover—such as “photographing screens with phones or taking screenshots”—Ping32 offers effective countermeasures.

• Driver-level anti-screenshot: Utilizing driver-level GDI protection technology, it not only blocks the Print Screen key and common screenshot tools like those in QQ and WeChat but also effectively protects against professional screenshot software like PicPick, comprehensively safeguarding high-value trading windows from illegal capture.
• Smart watermarking: Supports dynamic display of full-screen or window watermarks containing terminal IP/MAC addresses, current time, and operating username. These watermarks appear either on the entire screen or when users open specified sensitive software (e.g., OA systems, sensitive contracts, trading terminals). This highly visible identification creates a strong psychological deterrent, discouraging attempts to photograph and leak information. Even if photos are leaked externally, enterprises can instantly identify the source via watermark information and immediately trace it back to the responsible individual.

5. Standardizing Removable Storage Authentication to Minimize USB-Related Risks

Addressing the uncertainties of USB drive usage arising from numerous branch offices and frequent mobile work, Ping32 provides a refined removable storage management solution.

• Dedicated drives and identity authentication: Ping32 can precisely identify and block the connection of employees’ personal USB drives or unknown devices. Only USB drives that have been uniformly authorized and authenticated by the enterprise can be used on endpoints. The system can assign independent encryption keys to different departments using strong encryption algorithms, establishing “department-specific encrypted drives” for internal use only, thereby solving data leakage problems caused by lost USB drives, unauthorized removal, or cross-departmental mixing.
• Granular permissions and full auditing: It flexibly sets read/write permissions for USB drives (e.g., read-only, read-write, disabled). Furthermore, regardless of when a user plugs in or removes a USB drive or what document copy operations are performed, the system generates detailed audit reports including source path, destination path, and file size, ensuring that file exchanges via physical media are completely transparent and compliant.

6. Strictly Controlling the Departure Period with Full-Lifecycle Operational Auditing

Targeting high-risk endpoints during personnel transfers and resignations, Ping32 provides dynamic data backup and traceability locks.

• Full-lifecycle operation auditing: Every operational node—from creation, access, renaming, modification, copying, to deletion and transfer—is meticulously recorded.
• Transfer traceability: Invisible flow information is embedded within documents, automatically recording the chain of circulation across various computer nodes within the enterprise. When suspicion arises that a core sensitive file has been stolen, administrators can use the flow information to easily reconstruct the entire process of who created the document, who edited it, and through which software it was outbound or transferred.
• Forced backup before anomalous operations: Coupled with a real-time data protection module, when an operator performs batch transfers, illegal modifications, or file deletions on an endpoint, Ping32 can automatically detect file changes and back them up in full or from specified paths in the background. This preserves crucial forensic evidence in the event of leakage while effectively preventing core digital assets and work outputs from being maliciously destroyed.
