Eighty-eight percent of U.S. businesses claim confidence in their current distributed denial of service mitigation, despite 69% having suffered a successful DDoS attack in the last 12 months.

The Research conducted by Sapio Research on behalf of CDNetworks surveyed 500 senior IT personnel in the US, UK, Germany, Austria and Switzerland, also found 88% of U.S. businesses believed new DDoS attacks to be likely or almost certain in the next 12 months.

The report revealed DDoS attacks are growing in both number and size, and their aftershocks are taking over headlines. "The Mirai botnet attack that targeted Dyn in October 2016, which caused major service providers including Twitter, Amazon and the BBC to be undermined, is a classic example of how cybercriminals take advantage of the remarkable increase in connected devices available for recruitment to an en masse attack." This, plus the overall growth in criminal sophistication, has led to a far greater danger of enterprises suffering a DDoS attack.
