Maintain documentation for network architecture, configurations, and security policies
Collaborate with IT and security teams to align network infrastructure with broader security standards
Support compliance efforts related to network and IT security requirements
Stay current on emerging network security threats and Aruba/HPE platform capabilities
What You Bring
Strong hands-on experience with Aruba networking and security products
