Security

1. Security Overview

LinkGuard.ai implements a defense-in-depth security strategy, layering multiple security controls to protect your data at every level. Our security program is designed around three core principles:

2. Infrastructure Security

Our infrastructure is built on modern cloud architecture with security at every layer:

2.1 Hosting & Network

• Cloud Infrastructure: Hosted on enterprise-grade cloud providers with SOC 2 Type II certification
• Network Isolation: Production environments are isolated using Virtual Private Clouds (VPCs) with strict firewall rules
• DDoS Protection: Multi-layer DDoS mitigation protects against volumetric, protocol, and application-layer attacks
• Web Application Firewall: WAF rules filter malicious traffic and block common attack patterns

2.2 Server Security

• Hardened Configurations: All servers follow CIS benchmarks with unnecessary services disabled
• Regular Patching: Operating systems and dependencies are updated with security patches within 48 hours of release
• Container Security: Application runs in isolated Docker containers with minimal privileges
• Immutable Infrastructure: Servers are replaced rather than modified, preventing configuration drift

3. Data Protection

3.1 Encryption

• In Transit: All data transmitted between your browser and our servers uses TLS 1.3 encryption with strong cipher suites
• At Rest: Database encryption using AES-256 protects stored data
• Secrets Management: API keys, credentials, and sensitive configuration are stored in encrypted vaults
• Password Security: User passwords are hashed using bcrypt with 12+ rounds, making brute-force attacks impractical

3.2 Data Handling

• Data Minimization: We collect only the data necessary to provide our services
• Secure Deletion: Deleted data is permanently removed from primary storage within 30 days
• Backup Encryption: All backups are encrypted with separate keys stored in secure key management systems
• No Third-Party Sharing: Your backlink data is never sold or shared with third parties for marketing purposes

4. Access Control

4.1 User Authentication

• Secure Authentication: Support for email/password, Google OAuth, and Telegram authentication
• Session Security: JWT tokens with short expiration times, stored in HTTP-only cookies
• Account Lockout: Progressive delays after failed login attempts to prevent brute-force attacks
• CSRF Protection: All state-changing requests require valid CSRF tokens

4.2 Internal Access

• Principle of Least Privilege: Team members have access only to systems necessary for their role
• Multi-Factor Authentication: Required for all internal access to production systems
• Access Reviews: Regular audits of access permissions with prompt revocation when no longer needed
• Audit Logging: All administrative actions are logged and monitored

5. Compliance & Standards

We adhere to industry standards and regulations to ensure your data is handled responsibly:

• GDPR: Full compliance with EU General Data Protection Regulation. See our GDPR page for details.
• CCPA: California Consumer Privacy Act compliance for US users
• OWASP: Development practices aligned with OWASP Top 10 security guidelines
• Data Localization: EU customer data can be stored within the European Economic Area upon request

6. Security Monitoring

Continuous monitoring helps us detect and respond to threats quickly:

• 24/7 Monitoring: Automated systems monitor infrastructure health, security events, and anomalies around the clock
• Intrusion Detection: Network and host-based intrusion detection systems alert on suspicious activity
• Log Analysis: Centralized logging with automated analysis to identify potential security incidents
• Vulnerability Scanning: Regular automated scans of infrastructure and application code for known vulnerabilities
• Dependency Monitoring: Continuous monitoring of third-party libraries for security advisories

7. Incident Response

We maintain a comprehensive incident response plan to handle security events:

1. Detection: Automated monitoring and alerting systems identify potential incidents
2. Assessment: Security team evaluates severity and impact within 1 hour of detection
3. Containment: Immediate actions to limit the scope and impact of the incident
4. Eradication: Root cause analysis and complete removal of the threat
5. Recovery: Restoration of affected systems with verified integrity
6. Communication: Affected users notified within 72 hours as required by GDPR
7. Post-Incident Review: Analysis to prevent similar incidents and improve response

8. Responsible Disclosure

We value the security research community and welcome responsible disclosure of vulnerabilities.
