Introduction

At Pline, data privacy is fundamental. We have designed our platform to ensure that sensitive information remains protected at all times — not just in transit or at rest, but also during processing. Whether through our browser-based tools or server-side infrastructure, Pline enables a zero-knowledge data privacy model for enterprise customers: data remains encrypted in such a way that even Pline cannot access or interpret it.

This whitepaper outlines how Pline protects your data through client-side encryption and secure processing, and why this matters to organizations that prioritize privacy, compliance, and control.

How Enterprise Data Remains Private

Pline ensures enterprise-grade privacy through two key pillars:

1. Client-Side Encryption (In-Browser)

When users collect or input data using Pline's browser extension, that data is encrypted immediately within the browser environment before it leaves the device.

• Encryption at Source: Data is encrypted using strong industry-standard algorithms (e.g., AES-GCM, ECC) via the browser's native cryptographic capabilities (Web Crypto API).
  
  

• Key Ownership: Encryption keys are generated and retained entirely on the client side. At no point are the keys shared with Pline or transmitted externally. This guarantees that Pline systems — including administrators and backend services — never have access to the raw content.
  
  

• Performance Optimization: Modern encryption is performed efficiently within the browser, ensuring there is no perceptible impact on user experience.

By encrypting data before it ever leaves the user’s environment, Pline enforces a zero-knowledge design — ensuring that only authorized users can decrypt and view the data.

2. Confidential Processing in Secure Enclaves

When enterprise customers require server-side data processing (e.g., scheduled automation, cloud-based workflows), Pline maintains the same level of confidentiality by utilizing confidential computing infrastructure.

• Secure Enclaves: Data is processed within isolated environments called Trusted Execution Environments (TEEs), such as Intel SGX or AWS Nitro Enclaves. These environments isolate encrypted data and computation from the host system, ensuring that even privileged system operators cannot view the data.
  
  

• Encrypted Memory: All memory used within the enclave remains encrypted. Decryption occurs only inside the CPU, ensuring runtime data confidentiality.
  
  

• No Exposure Risk: Even if the server or hypervisor were compromised, enclave protections prevent data from being accessed or tampered with.
  
  

This means Pline can process encrypted data securely — without ever having access to the unencrypted information.

Why It Matters

• User Control: Enterprises retain full ownership of their encryption keys and data. Pline cannot decrypt or inspect customer content.
  
  

• Compliance Ready: The zero-knowledge model aligns with stringent data protection standards such as GDPR, HIPAA, and SOC 2. Encrypted data is often exempt from breach reporting under regulatory frameworks.
  
  

• Minimized Risk: In the event of a breach or system vulnerability, data remains unreadable and secure, significantly reducing legal and reputational exposure.

  
  

Real-World Applications

Organizations across industries benefit from Pline’s privacy-first architecture:

• Healthcare: Secure handling of patient data and research records while maintaining HIPAA compliance.

• Financial Services: Encrypted workflows for sensitive transactions and audit data.

• Enterprise Collaboration: Secure cross-department or cross-border data sharing with full control over confidentiality.

Summary

Pline delivers enterprise-ready data privacy through a true zero-knowledge approach. With client-side encryption in the browser and secure enclave-based processing in the cloud, organizations can confidently use Pline for sensitive workflows — without compromising control or compliance.

This model ensures that data remains private by design. Even if compromised, the information is never exposed — because Pline is built to never have access to it.

For enterprises seeking secure data automation and extraction, Pline offers the confidence and protection of end-to-end encryption — with performance and usability built in.

Pline sets a new standard for secure data infrastructure — enabling privacy-preserving automation and data processing that aligns with enterprise-grade confiden
