  • Complete control over security patches and updates
  • No dependency on third-party security vulnerabilities
  • Rapid response to emerging threats
  • Consistent security standards across the platform

Authentication & Access Control​

Passkey Authentication: Passwordless Security for the Modern Era​

Embrace the future of secure logins with passkeys. Utilizing public key cryptography, passkeys eliminate the need for traditional passwords, effectively preventing credential theft and offering a frictionless user experience through biometric authentication.

Features:

  • Public key cryptography eliminates password vulnerabilities
  • Biometric authentication support
  • Protection against phishing attacks
  • Seamless user experience

Multi-Factor Authentication (2FA) and Single Sign-On (SSO)​

Enhanced login security through multiple authentication options:

  • Two-Factor Authentication (2FA)

    • Support for authentication apps (Google Authenticator, Microsoft Authenticator)
    • Additional security layer for traditional logins
    • Time-based one-time passwords (TOTP)

  • Single Sign-On (SSO) & SAML

    • Seamless integration with Google sign-in
    • Microsoft authentication support
    • Simplified access management
    • Maintains high security standards
    • Support for SAML Login

IP Address Locking: Granular Control for Enhanced Protection​

Restrict administrator access to designated IP addresses, creating a fortified perimeter around your PBX.

Implementation:

  • Whitelist specific IP addresses for admin access
  • Reduce attack surface significantly
  • Prevent unauthorized access attempts
  • Granular control per administrator role

Network Security​

Advanced Rate Limiting: Defending Against SIP Attacks​

Protect your PBX from SIP-based flooding and attacks with Vodia's powerful rate limiting features.

Capabilities:

  • Control connection rates per IP address
  • Manage authentication attempts for existing tenants
  • Protect non-existent tenants from enumeration attacks
  • Comprehensive logging for threat analysis
  • Automatic blocking of suspicious traffic patterns

Encrypted Communications: Securing VoIP Traffic​

Vodia implements multiple layers of encryption to protect voice communications:

  • SIP TLS Encryption

    • Secure SIP signaling
    • Prevention of man-in-the-middle attacks
    • Certificate-based authentication

  • WebRTC over HTTPS

    • Encrypted browser-based communications
    • End-to-end encryption for web clients
    • No plugin requirements

  • Flexible Port Configuration

    • Ability to use alternate SIP ports
    • Avoid common port scanning attacks
    • Custom port configuration per deployment

Infrastructure Security​

Automatic SSL Certificates: Securing Web Traffic​

Vodia's built-in Let's Encrypt integration ensures all web traffic is encrypted:

  • Automatic SSL certificate generation for new tenants
  • HTTPS enforcement for all web interfaces
  • Certificate auto-renewal
  • No manual certificate management required
  • Protection of sensitive configuration data

Secure Phone Provisioning: MAC Address Control​

Advanced security for device provisioning:

MAC-Based Authorization:

  • Administrators authorize specific devices by MAC address
  • Time-limited provisioning windows
  • Automatic strong password generation for:
    • SIP credentials
    • Web interface access
  • Elimination of default or weak passwords
  • Secure auto-provisioning protocols

Distributed Architecture: Scalability and Redundancy​

For enterprise deployments requiring maximum reliability:

  • Multi-Server Distribution

    • Spread extensions across multiple servers
    • Geographic distribution across data centers
    • Regional deployment options

  • Benefits:

    • Enhanced scalability for growth
    • Built-in redundancy and failover
    • Improved performance through load distribution
    • Disaster recovery capabilities

Fraud Prevention​

Comprehensive Toll Fraud Prevention​

Vodia offers multiple layers of protection against toll fraud:

Registration Controls​

  • Limit the number of registrations per extension
  • Prevent credential sharing
  • Detect and block suspicious registration patterns

Call Volume Management​

  • Set call volume limits per tenant
  • Configure restrictions per SIP trunk
  • Real-time monitoring of call patterns
  • Automatic alerts for unusual activity

International Call Protection​

  • PIN-based authorization for international calls
  • Country-specific dialing restrictions
  • Time-of-day calling rules
  • Weekend and holiday restrictions

Credit Management​

  • Outbound call credit limits at domain level
  • Per-extension spending controls
  • Real-time balance monitoring
  • Automatic call termination when limits reached

Security Best Practices​

Implementation Recommendations​

  1. Enable all applicable security features during initial setup
  2. Regularly review and update IP whitelists
  3. Monitor rate limiting logs for attack patterns
  4. Implement PIN codes for sensitive destinations
  5. Use distributed architecture for critical deployments
  6. Regular security audits of user permissions
  7. Keep the system updated with latest security patches
