With cyberthreats increasing in size and scope, businesses are scrambling to find new ways to protect their financial and human capital assets.

In particular, as employees bring mobile devices onto corporate networks, and with new attack variants being introduced almost daily, small and mid-sized businesses have no way of keeping up.

Examples of recent Mirai-generated web outages are the Dyn attack which took down or significantly slowed sites like Airbnb, Twitter, the New York Times, CNN, Fox News, Netflix and many other popular domains in late October of this year, as well as the attack that temporarily took down security expert Brian Krebs’ KrebsOnSecurity website in September.
