I have used other solutions in the past.

We switched from our previous solution because of the scalability of OP5, but that was done before my time with the company so I don't know what they used before.

If we go back 15 years, in that time span our clients have not used a different monitoring solution. Today, everyone has some kind of monitoring system. And if they don't, they've been living under a rock, or it's a new company.

We have used various monitoring products but at the moment, OP5 is our main one.
