Paid or free solution

  1. Use paid solution
    • Use it and strip down to what you really need
      + ready to go
      + sort of giving away responsibility
      – costly
      – might be more/else than you need
      – not opensource
  2. Use free solution
    • Use opensource tools and build your own testing
    • If you find out you need more, you have a good input for company providing the paid solution
      + free and opensource
      + your control
      + some of it can be implemented immediately
      – might take time to put right complete solution in place
