Pros
There are no pros for working with Flexera Software. I'll never recommend someone to work here. It is what it is.
Cons
I found no pros being an employee of Flexera Software. I was part of the Secunia acquisition, and after stringing us along for a few months, they came in and dropped a bomb and shut down our office leaving the employees to handle the shut down and emptying of the office. Secunia WAS great until Flexera got their hands on us. They ruined a great thing. If you're part of this company, or part of a company they are looking to acquire, start looking for a job now. You'll hate it. Top heavy executives who care only about revenue and not the employees who bust their hump to make that revenue. They absolutely cannot be trusted, including HR.
