The COVID-19 pandemic forced businesses of all shapes and sizes to make rapid changes in how they operated, with employees predominantly working remotely and sensitive data and systems being accessed from outside the office.
For many, this triggered an increased reliance on remote-access infrastructure and cloud-delivered services. IT departments rushed to install, expand, or upgrade remote desktop access (RDA) servers, virtual private network (VPN) concentrators, and remote access routers to meet surging workforce demand for remote access to data centers. Moreover, widespread reliance on video conferencing apps forced many businesses to upgrade enterprise wide-area network and local-area network capacity, as well as to reevaluate routing and DNS resolution paths within the network. Enterprises also quickly began to adopt software-as-a-service (SaaS) and cloud applications to handle the large scale and rapid modifications required by the sea change in remote work practices.
