Case Study: Restoring Secure VPN Access for a Local Law Firm in Allen, Texas

How NerdsToGo McKinney helped a law firm reconnect remote employees using a WatchGuard firewall 

Overview 

When a local law firm in Allen, Texas experienced VPN issues, their attorneys and staff suddenly lost secure access to office resources while working from home. This disrupted productivity and created potential security risks for sensitive legal data. NerdsToGo McKinney stepped in to diagnose the problem, reconfigure the environment, and restore reliable, secure remote access. 

The Challenge 

The firm relied on a Virtual Private Network (VPN) to securely access: 

  • Case files and shared drives 
  • Legal documents and client records 
  • Office applications and internal resources 

Their remote access environment was built around a WatchGuard firewall, but VPN connectivity had become inconsistent and eventually failed for multiple users. Employees were unable to connect from home, delaying work and increasing operational frustration. 

Our Approach 

Our team performed a business-focused troubleshooting process, starting with a full review of the network configuration and security policies. 

Key findings included: 

  • VPN configuration mismatches causing authentication failures 
  • Firewall policy settings that needed adjustment 
  • Inconsistent remote client settings across user devices 

We implemented the following solution: 

  • Reviewed and corrected VPN configuration on the WatchGuard firewall 
  • Updated firewall policies to allow secure and reliable remote access 
  • Reconfigured user permissions and VPN profiles 
  • Standardized remote connection settings across staff devices 
  • Tested connections for all employees and validated stability and security 

Results 

After remediation, the law firm achieved: 

  • Full VPN connectivity restored for all employees 
  • Reliable, secure remote work access from home 
  • Improved stability and fewer connection issues 
  • Greater confidence in the firm’s IT security posture 

Why This Matters for Law Firms 

Law firms handle confidential client information and frequently require secure remote access. A properly configured firewall and VPN help protect data, reduce cybersecurity risk, and ensure staff can work productively from any location.
