SonicWall has confirmed that the End of Support (EOS) date for SMA100 devices has been moved forward to October 31, 2025. Recent, high-profile vulnerabilities have made these legacy VPN appliances prime targets for exploitation, including the deployment of backdoors by threat actors. To protect your organization and maintain a secure environment, we recommend migrating to a modern, secure remote access solution as soon as possible.

What’s Changing and Why Now?

SonicWall recently confirmed that all SMA100 appliances will be disabled entirely on October 31, 2025, resulting in complete loss of functionality. Support and firmware updates will also cease on this date.

The risks are real and imminent—continuing to run these appliances is no longer defensible.

Immediate Impact of the October 31 Cutoff

After EOS, SMA100 devices will lose connectivity and stop functioning entirely. If you have yet to begin migration planning, now is the time to speak with a Logically team member—delaying puts your remote access infrastructure, data, and reputation at risk.

What Your Peers are Facing

In recent months, most SMA100 vulnerabilities have appeared in CISA’s Known Exploited Vulnerabilities catalog, signaling widespread exploitation risk.

Google’s Threat Intelligence Group confirms active attacks since mid‑2024, including backdoor deployment by UNC6148.

Protect Your Access, Protect Your Business

The stakes are high. With migration options in place and attack campaigns underway, doing nothing is not an option. A modern, secure platform like SonicWall’s Cloud Secure Edge ensures seamless, compliant, high-performing remote access, setting you up for long-term resilience.

Schedule a discussion with the Logically team now to assess your needs and map your migration path confidently.
