Experience

Deployment and Implementation of a SASE Solution for Zero Trust

I participated in deploying and implementing a SASE solution to operationalize the idea of Zero Trust through UEBA, posture assessments, and adaptive MFA. I also enabled other features of the SASE solution, such as a CASB, SWG, and DLP—the pillars of an effective Zero Trust strategy. Finally, I implemented ZTNA to control access to the company's in-house applications from users anywhere in the world and centrally enforce access policies.

Security Operations Center (SOC) Development

I participated in building a SOC for our company, which involved deploying and implementing a SIEM solution and integrating different log sources with the solution. I supervised and collaborated with the SOC team to investigate, tune, and respond to security events and incidents. I also worked on the creation of SOAR workflows to automate manual tasks in the incident response process. Finally, I procured and implemented a threat intelligence solution for the SOC.
