In 2020, 31 percent of enterprises experienced distributed denial of service (DDoS) attacks. Next to DDoS attacks, enterprises experienced other kinds of attacks and threats, too. At the same time, enterprises had to defend a more vulnerable network environment due to a general shift to hybrid work solutions as a result of the COVID-19 pandemic. Enterprises do not expect threats to subside in the near future.
