We purchased a relatively small Aruba VPN appliance. Unfortunately, it was not a well-designed VPN appliance product. I think the vendor did not provide us with the best solution. At that time, the world and our company faced the first COVID lockdown, and everybody had to work from home. During this time, the small VPN appliance was overwhelmed by the number of connections, and we experienced many issues. Firstly, it turned out that the firmware was buggy. When around 100 to 300 users tried to connect at the beginning of the day, the appliance would crash, and the users would not be able to connect. We had to escalate the issue to the manufacturer, and they had to release new firmware to resolve the problem, which took around one week. As you can imagine, during the COVID-19 pandemic, everyone had to work from home, and we were struggling to connect to the VPN because of the firmware bug. It took Aruba at least one week to resolve the issue. Another major pain point we faced was with the VPN client. At the time, we were using the Windows 7 operating system on the client machines. Unfortunately, we could not identify the precise circumstances in which the Aruba VPN client could not establish a connection. This was very, very disappointing for us and caused a lot of problems for our department. We had around 500 to 600 users who wanted to connect, and at least 50 to 60 users, or about 10% of the users, were unable to connect each day due to this anomaly. We were not able to identify the root cause of the problem. We collected and provided all the logs that the local support partner requested. Unfortunately, neither the Hungarian local support partner nor the Aruba headquarters could identify the root cause of how and why the Aruba VPN client could not establish a connection. So, it felt like a bad spot. Each day, users were praying to connect over the VPN and to be able to work that day. Aruba VPN sometimes worked, and sometimes it didn't. We were very disappointed and had to switch to a different supplier as soon as possible. We switched to a Cisco product and were very satisfied with the Cisco VPN.
