I’ve even seen an appliance set to ‘fail-open’ that should pass traffic even if the device were dead, but failed to do so when needed. This article is more about the deployment of Cisco Umbrella in our environment, so I won’t go on with all the numerous other benefits of Umbrella, suffice it to say that I am a believer in the product, and it was an enormous improvement over our previous solution.
