SonicWall Firewall Compromise: A VPN Security Wake-Up Call for SMBs
Arctic Wolf has issued a high-priority security bulletin highlighting a sharp rise in SonicWall VPN compromises linked to the Akira ransomware group. These targeted attacks begin with unauthorized VPN access and quickly escalate to lateral movement, data theft, and full-scale ransomware deployment which often results in major financial and operational disruption.
As a trusted Managed IT Services Provider, Louisville Geek is taking swift and proactive action to protect our clients:
Effective immediately, we are disabling SonicWall SSLVPN access for all known affected environments until a validated patch is released.
Why SonicWall SSLVPN Access Is Being Disabled Due to Security Threat
The current threat targets SonicWall SSLVPN endpoints, specifically through configurations where remote users connect using SonicWall NetExtender software. If your business uses NetExtender to access the network remotely, you are impacted by this vulnerability.
We are disabling SSLVPN access in these cases because:
- A working exploit is actively circulating
- No validated patch has been released by SonicWall
- MFA is not sufficient to block this particular threat vector
- Endpoint trust cannot be guaranteed while the vulnerability remains open
By disabling access now, we’re eliminating one of the most common attack surfaces being used today.
What the SonicWall SSLVPN Shutdown Means for Your Remote Access and Operations
If your employees normally connect to your network remotely using SonicWall NetExtender, they will temporarily lose access until a vendor patch is released and validated. Our Service Desk is actively assisting impacted organizations in setting up secure alternatives such as:
- Remote desktop gateways
- Secured cloud access
- Temporary on-site access plans
While this may cause short-term inconvenience, this move is essential to:
- Prevent data breaches and ransomware incidents
- Maintain business continuity and operational stability
- Demonstrate strong cybersecurity leadership
Louisville Geek’s Cybersecurity Response to SonicWall Threat
Disabling SSLVPN is one important step Louisville Geek is taking to strengthen IT security across client environments. Here are the other actions we’re implementing:
24/7 Monitoring with Arctic Wolf MDR
All SonicWall firewalls and VPN logs, including authentication attempts, are being forwarded for real-time threat detection.
Mandatory MFA Across All Remote Access Points
MFA is required across all alternative remote access methods to reduce the risk of credential compromise.
Firewall and VPN User Account Audits
We are identifying and removing any inactive or unnecessary accounts that may be leveraged for unauthorized access.
Security Features Fully Enabled on SonicWall Devices
Botnet filtering, intrusion prevention, and gateway antivirus services are enabled and verified.
Password Policy Enforcement and User Training
We’re working with clients to improve password policy enforcement and user education to harden access credentials.
Next Steps If Your Business Uses SonicWall NetExtender for Remote Access
If you’re unsure whether your business is affected, ask your team this question:
Do we use SonicWall NetExtender for remote access?
If the answer is yes, your environment falls within the scope of this threat, and your SSLVPN access has likely been disabled by our team. If you’re not a current Louisville Geek client, this is a key moment to assess the integrity of your perimeter defenses.
Proactive Cybersecurity in Action: Mitigating the SonicWall SSLVPN Threat
The SonicWall SSLVPN threat is a clear example of how fast-moving vulnerabilities demand clear, decisive action. Disabling remote access tools is never ideal but in this case, it’s necessary to prevent a much more disruptive outcome.
Louisville Geek is committed to helping our clients stay ahead of the threat curve, not behind it. We’ll continue monitoring the situation closely and will re-enable secure remote access once SonicWall releases and verifies a patch.

Looking Ahead: Is It Time to Move from SonicWall to Meraki?
While we are focused right now on mitigating this specific threat, we’re also looking ahead. For clients nearing their SonicWall firewall renewal, Louisville Geek will be initiating conversations about whether a shift to Meraki or another modernized security platform is the right long-term move.
Meraki offers:
- Cloud-managed security appliances
- Automatic firmware updates
- Simplified remote management
- Strong native integration with other networking tools
It’s not about switching vendors for the sake of it. It’s about identifying tools that align better with today’s evolving threat landscape and our ability to secure your environment with agility.
If your renewal is approaching or you’d like to proactively evaluate alternatives, our team is happy to start that discussion with you.
