Swiss Army knives are the quintessential symbol for an all-in-one device. But really they are only as good as the functions that were thought up ahead of time, then added once and for all to the knife. If you don’t buy the one with the scissors, then there’s no adding scissors later on when you need them. Network security is no different. Fixed function firewalls, fixed function routers, load balancers and packet brokers are all feature rich but only if the manufacturer designed the feature in (and you pay to turn it on). Handy up until now but not sustainable going forward.
Corsa has been working for a while to create a better way to add flexible, dynamic, adjustable security to your network. It’s all built on SDN principles and harnesses the dynamic power of SDN service chaining to build out network security that provisions functions virtually – at any scale. I recently had the opportunity to discuss Corsa with TAG Cyber‘s Ed Amoroso and it took less than 5 minutes for him to get it. For him, Corsa is a software-defined firewall solution. His article is here and it will make you think about the practicality of Swiss Army knives going forward.
