The advantage to unmanaged switches when it comes to performance is that you can plug and play immediately with your network. There’s no need to set anything up, and it has in-built QoS services to ensure its working well. With a managed switch, however, you can prioritize channels at will, ensuring that you get the best performance where you need it. Furthermore, features like Priority SNMP, which allow for remote troubleshooting of the network, also make it even easier to check for any issues impacting that performance, allowing you to implement fixes if necessary.
Unmanaged switches, on the whole, have very basic security. They’re secured by ensuring you have no vulnerabilities from system to system, which accessories like a lockable port cover can ensure no-one is tampering with the device directly. Managed switches have some major security benefits, such as the ability to monitor and control the network to shut down active threats, protection for data, control, and management plan. The security features differ from different managed switchers, from network communication encryption, access control lists that keep out unauthorized users, and VLANs can also be used to create temporary or limited access to your network for those that normally shouldn’t have access.
