  • Worked on building redundant AWS VPN connections with business partners in AWS Cloud. Expertise in building IKEv1/v2 VPN connections on both checkpoint and Palo Alto firewalls. Also actively worked on troubleshooting connectivity and latency problems with both IKEv1 and IKEv2 AWS VPN connections.
  • Configure and deploy a datacenter in the AWS Cloud spanning Virtual Private Cloud (VPC) across multiple regions, Transit Gateway, Transit VPC (With Cisco CSR’s for VPN termination), AWS VPN connections, Instances (EC2), Public and Private Subnets, and custom third party traffic filtering (firewall) solution (Palo Alto).
  • Troubleshoot complex issues in AWS Cloud environment by performing VPC traffic mirroring, analyzing flow logs, and analyzing packet captures taken on client and EC2 instances.
  • Build and configure AWS infrastructure resources like S3, Route 53, Auto Scaling via Cloud Formation JSON templates and custom python scripts executed on lambda.
  • Deploy and roll out Remote access VPN Solution i.e., Global Protect Client to all the Windows/MAC users across the environment successfully and troubleshoot the user issues.
  • Configure Service connections from Service Connection firewalls to OnPrem firewalls to have site to site VPN connection for GPCS (GlobalProtect Cloud Services/Prisma Access) deployment.
  • Deploy multiple tenants in Prisma access to provision for routing of multiple thirdparties.
  • Develop documentation on end user experience when logged into Prisma access.
  • Setup split routing scenarios for Skype/Microsoft teams and deploy Pre-logon using Prisma access.
  • Leverage Layer7 capabilities of Palo Alto firewalls and build the firewalls with APP-ID, User-ID and advanced threat protection profiles like Anti-Virus, Anti-Spyware, Vulnerability Protection, Wildfire (SandBox environment) for Zero-day attacks.
  • Work with OPSEC tools like Firemon to perform the entitlement review process to validate if a rule is being used or a user group is still required access using the firewall rules.
  • Collaborate with Level2 and Level1 teams and train them on the various projects and educate them on existing projects to make the processes more efficient.
  • Work on AWS Cloud Hosting environment performing the Inbound SSL Decryption to decrypt the traffic coming inbound and re-encrypt the traffic leaving the firewall.
  • Installing the certificates on Application Load Balancers using ACM and adding the rules for various listeners.
