Job Description

Network security plays an ever-increasing role in our clients' businesses today. This preventive mechanism against vulnerability to data theft, can lead to an uncontrolled access-list sprawl, lack of methodology standardization for firewalls, and complex operations due to non-conforming architectures. At Deloitte, we help clients reimagine network security, not only to make it more manageable, but also to make it pervasive across the organization's environments. For example, as cloud adoption grows and transforms into business as usual, network security must account for environments beyond the hardware firewall in order to provide a comprehensive solution. Security is not a destination, but rather a journey that Deloitte Network Security practitioners embark on to help clients mitigate cyber risk in a borderless world.

Work you'll do

Our practitioners work collaboratively within integrated, cross-functional teams to provide broad-based network transformation projects to provide value for our clients. Network Security practitioners will be expected to bring infrastructure security expertise, helping other practitioners better estimate the effort involved with network transformation, identifying key milestones that need to be achieved to meet a client's ask, and be able to translate business requirements into technical specifications. Network Security practitioners are also asked to help perform current-state assessments for clients looking for an object perspective and provide thought leadership on where the industry is heading and the appropriate next steps. Moreover, Network Security practitioners are called upon to help propose, design, and implement modern network security enclaves that tick all the boxes that clients typically ask for, including scalability, flexibility, availability, and programmability. Finally, Network Security practitioners are expected to help client IT teams adopt new methods, own their new security infrastructure and help mentor junior Deloitte practitioners interested in network security.
