Built an MSSP (Managed Security Service Provider) solution based on enterprise products from McAfee.
We sold the products McAfee Endpoint Enterprise antivirus and encryption as a service.
I defined, initiated, planned, executed, control/monitor/administrate and sold the solution.
Today these solution already exist. At the time of this project there was no supplier that had this so we built it from scratch, which was a struggle. But we fond a way to build a very stable solution that had during the lifetime of 5 years only minutes of downtime.
