Why SSL VPNs Put Your Business at Risk

October 8, 2025

For years, businesses have relied on VPNs (Virtual Private Networks) as the “secure” way to connect remote workers to company systems. But the truth is, VPNs, especially SSL VPNs, have become one of the biggest security liabilities in today’s threat landscape.

Hackers aren’t breaking into businesses by guessing passwords anymore. They’re going straight after the tools you use to connect: VPNs and firewalls.


The Problem with VPNs

VPNs were designed to create a tunnel between a remote user and your company network. Once that tunnel is open, the user (or attacker) has broad access inside your network. It’s like giving someone the keys to the entire building when all they needed was access to one office.


When attackers compromise a VPN, they don’t just get a foot in the door, they’re sitting in your lobby with access to everything.


SSL VPNs and SonicWall Vulnerabilities

In the past few years, we’ve seen a flood of zero-day vulnerabilities targeting SSL VPNs and firewalls. One of the most high-profile examples is the SonicWall SSL VPN vulnerability, which allowed attackers to bypass authentication and gain access directly into company networks. They didn't even need a password!


That wasn’t a one-off event. Almost every firewall vendor, Fortinet, Cisco, Palo Alto, SonicWall, and others, has dealt with critical VPN-related zero-days. Cybercriminals actively scan the internet for exposed VPN portals, waiting to pounce on organizations that haven’t patched within hours of a new exploit being discovered.


Why This Puts Your Business at Risk

  • Single Point of Entry: VPNs often provide attackers with wide-open access once compromised.
  • Zero-Day Exploits: Hackers don’t wait, many breaches happen before patches are even available.
  • Credential Theft: If an employee’s VPN password is stolen, attackers bypass your defenses.
  • Compliance Risks: Breaches through VPNs can expose sensitive data, leading to fines and legal issues.


The Better Approach: Zero Trust Remote Access

Instead of relying on VPNs, modern businesses are adopting Zero Trust solutions that limit access to only what a user needs, when they need it. This ensures that even if an account is compromised, attackers don’t get the keys to your entire network.


What You Should Do Next

If your business is still using SSL VPNs or traditional VPNs, you’re already at risk. Hackers are actively targeting these systems, and history has proven that more vulnerabilities will continue to surface.


It’s time to move away from outdated VPN technology and adopt modern security practices that keep your business safe.
