Juniper EX4550 MACsec License for Agg Switches | Enterprise Security

Protect traffic at the switch edge with MACsec licensing for EX4550 aggregation switches. This license enables link-layer encryption for environments that need stronger protection across uplinks, inter-switch links, and other trusted network segments carrying sensitive data. For infrastructure teams, MACsec adds a practical control point where traffic is most exposed without forcing a redesign of the network. It helps safeguard data in transit while keeping the operational model aligned with Juniper EX4550 deployments. That matters in regulated environments, segmented enterprise networks, and campus backbones where confidentiality requirements extend beyond basic access control. Choose this license when the network design is already built around EX4550 aggregation switching and you need to extend security deeper into the fabric. It is a targeted way to raise the protection level of critical traffic while preserving the performance and manageability expected from the platform.
