Successfully orchestrated that move and configured OSPF routing across MPLS circuits so all three sites could communicate, and all traffic was optimized for efficient communication. • Configured Cisco 9300 switch stack and moved our network from the One Union location to the current location at Rainier Square in downtown Seattle. • Updated the IOS for Cisco and Juniper switch stacks. • Ran Nessus scans on the entire network to find and fix vulnerabilities. • Using Microsoft Endpoint Configuration Manager 2211, I created and deployed several application packages. • Managed Group Policy Objects. • Managed the Palo Alto PS-450 and PA-850 NGFW’s to include the upgrade of the PAN-OS from v8.1 to v10.2.2. Also managed URL blocking and security policies that block or allow traffic. • Secured the User-ID server monitoring and Group Mapping in Palo Alto by moving from WMI to WinRM over HTTPS on all the Domain Controllers. • Upgraded our CA environment from SHA-1 to SHA256 and ensured certificate renewals were happening properly with the new hashing algorithm. • Built new Server 2019 database and application servers in VMware and managed security updates and operating system patches the servers.
