How to Make Sure Your VPN Can Handle Demand From Remote Workers

By TBL Admin | Mar 16, 2020 | Insights, News

As many organizations are allowing their workforce to telecommute, VPN's are being put to the test.  If you're concerned your VPN cannot support the remote workforce demands that COVID-19 is creating, there are two crucial elements you can check that would limit your company's remote-working capabilities. 

1. Check Hardware Capabilities

When your hardware was first purchased, the need to remotely support your entire workforce was likely not anticipated. If your hardware is maxed-out due to VPN usage, all other processes will slow or halt entirely. Here are the maximums Cisco hardware can reach.

2. Check Licensing 

There are two type of AnyConnect licenses.

Old Licensing Model

The older perpetual licenses were applied on the ASA. You can issue “show version” on the ASA to check your license count.
