Basically, you are responsible for the security of your VPS by maintaining your server environment through maintenance and regular updates.
Each VPS also has its own firewall, which is intended to protect the environment from external attacks. It should also be regularly maintained with updates, just like the programs you use. Only then is the security of your VPS ensured.
The damage that can be caused by an attacker is difficult to estimate. Anything is possible, from simple data theft to a complete system crash. These can not only annoy website operators. Especially merchants and companies that focus on online sales must expect significant revenue losses if their online shop becomes unavailable due to an attack.
If you are unable to maintain your VPS yourself, we are happy to offer you our Solutions services. You can find more information here: dogado managed dedicated server
