Review Context

In the VPN world, OpenVPN has reigned supreme for nearly 20 years, synonymous with security and compatibility. However, WireGuard has recently emerged as a formidable challenger, boasting incredible speeds and a minimalist codebase.
Based on a deep-dive review by Techi Jack, we analyze enterprise usage, security architecture, and performance to reveal which protocol is the true "Game Changer."

Video Review: Full Technical Comparison

🏢 Round 1: Enterprise Features

In a corporate environment, a VPN is not just a connection tool; it's a management tool.

OpenVPN

  • Identity: Native LDAP / Active Directory support.
  • MFA: Built-in Multi-Factor Authentication.
  • Management: Mature GUI panels & group policies.

Verdict: Choice for Banks, Gov, & Large Corps.

WireGuard

  • Missing Features: No built-in user mgmt, MFA, or LDAP.
  • Philosophy: A kernel-level tunnel, not a full suite.
  • Best For: Cloud networking, privacy, geeks.

Verdict: Needs 3rd-party tools for enterprise use.


🛡️ Round 2: Security & Code Architecture

This is where WireGuard truly shines.

1. Attack Surface (Code Lines)

  • OpenVPN: Over 600,000 lines of code. This massive footprint means more places for bugs to hide. Auditing is extremely difficult, and it has a history of OpenSSL vulnerabilities.
  • WireGuard: Only 4,000 lines. Extremely lean. Security experts can audit the entire codebase easily. It has maintained a record of "Zero Major Security Incidents" so far.

2. Cryptography Comparison

💡 Final Verdict: Which One Should You Choose?

Expert Recommendation

A
Choose OpenVPN IF:
You are an enterprise IT admin needing LDAP user management, complex routing policies, or you specifically need TCP to bypass strict firewalls.
B
Choose WireGuard IF:
You are an individual, SOHO team, or speed enthusiast. You want a "Set and Forget" VPN that saves battery on mobile and offers state-of-the-art security.
