When I stepped into the role, I inherited a firewall infrastructure that had served the organization well for many years. However, as technology evolved, the hardware had reached the end of its lifecycle, and it was time to modernize. By implementing Palo Alto firewalls, we introduced advanced features like application-aware traffic rules, user ID-based policies, and centralized logging. Additionally, we integrated the firewalls with CrowdStrike SIEM to enhance threat detection and response.
