Security

Security Overview

PRIV Protocol's security philosophy, practices, and architecture.

Security Philosophy

PRIV Protocol is built with a security-first mindset. As a platform handling sensitive user data and financial transactions, we implement multiple layers of protection at every level of the stack.

Defense in Depth

Multiple security layers ensure that a single vulnerability cannot compromise the system.

Privacy by Design

User data is encrypted and anonymized by default. We collect only what's necessary.

Zero Trust Architecture

Every request is authenticated and authorized, regardless of origin.

Continuous Monitoring

Real-time threat detection and automated security scanning.

Security Architecture

Security Layers

Client-Side Security

Control	Implementation	Purpose
CSP	Strict Content Security Policy	Prevent XSS and injection attacks
SRI	Subresource Integrity	Verify external script integrity
Encryption	AES-256-GCM client-side	Encrypt data before transmission
Consent	Granular opt-in controls	GDPR/CCPA compliance

Network Security

Control	Implementation	Purpose
TLS	TLS 1.3 minimum	Encrypt data in transit
CORS	Tiered by endpoint	Prevent unauthorized cross-origin requests
Rate Limiting	Per-key limits	Prevent abuse and DDoS
WAF	Cloudflare WAF	Block malicious traffic patterns

API Security

Control	Implementation	Purpose
Authentication	JWT + API Keys	Verify request identity
Authorization	Role-based access	Limit actions per user/key
Validation	Zod schemas	Prevent injection and malformed data
Key Hashing	SHA-256	Secure API key storage

Data Security

Control	Implementation	Purpose
RLS	PostgreSQL policies	Multi-tenant data isolation
Encryption	AES-256 at rest	Protect stored data
Backups	Encrypted, geo-redundant	Disaster recovery
Retention	Configurable policies	Minimize data exposure

Smart Contract Security

Control	Implementation	Purpose
Audits	Third-party audits	Verify contract security
Timelock	48-hour delay	Governance action safety
Multi-sig	3-of-5 admin	Prevent single-point compromise
Upgradability	Transparent proxy	Emergency security patches

Compliance

PRIV Protocol maintains compliance with major privacy regulations:

Lawful Basis: Explicit consent for data processing
Data Minimization: Collect only necessary data
Right to Access: Users can export all their data
Right to Deletion: Full account and data deletion
Data Portability: Machine-readable export format
Privacy by Design: Built into architecture from start

CCPA (California)

Disclosure: Clear notice of data collection
Opt-Out: Easy opt-out mechanisms
Non-Discrimination: Equal service regardless of opt-out
Data Access: Free annual data access request

SOC 2 Type II

Security controls audited annually
Continuous compliance monitoring
Incident response procedures documented

Security Practices

Development

Secure SDLC: Security review at every development stage
Code Review: All changes require security-focused review
Dependency Scanning: Automated CVE detection
Static Analysis: SAST tools in CI/CD pipeline

Operations

Access Control: Principle of least privilege
Audit Logging: Complete activity trail
Incident Response: Documented runbooks
Security Training: Regular team education

Infrastructure

Isolation: Network segmentation
Hardening: CIS benchmark compliance
Monitoring: 24/7 security monitoring
Patching: Automated security updates

Vulnerability Disclosure

Bug Bounty Program

We operate a bug bounty program for responsible disclosure:

Severity	Reward Range
Critical	$5,000 - $25,000
High	$2,000 - $5,000
Medium	$500 - $2,000
Low	$100 - $500

Scope includes:

priv.io web application
api.priv.io endpoints
Smart contracts on Base
Browser extension
SDK libraries

Report to: security@priv.io

Responsible Disclosure

Report vulnerabilities privately
Allow 90 days for remediation
Do not access user data
Do not disrupt services

Security Checklist for Integrations

When integrating PRIV, ensure you follow these security practices:

API Key Management

Store keys in environment variables
Never commit keys to version control
Use separate keys for test/production
Rotate keys periodically
Revoke compromised keys immediately

Data Handling

Implement consent before tracking
Never log sensitive user data
Use HTTPS for all API calls
Validate webhook signatures
Sanitize user input before sending

Application Security

Incident Response
