Case Study: Multinational Biotech Company ensures telecommuter productivity with Keysight's SSL VPN Assessment Service

Global Biotech IT Group Ensures Telecommuter Productivity

Multinational Biotech Company, a top global biotech organization, faced a sudden, large-scale shift to work-from-home that strained its VPN infrastructure. After adding virtual and physical VPN appliances sized from vendor data sheets, employees reported inconsistent VPN quality of experience; the gateway vendor could not isolate the cause, so the IT team engaged Keysight and its SSL VPN Assessment Service to validate realistic capacity and performance.

Keysight executed a cloud-based, turn‑key SSL VPN Assessment Service that emulated thousands of VPN clients and tested real-world connection and throughput behavior. Keysight proved the gateways could sustain the planned 4,000 and 6,000 concurrent tunnels but discovered one site’s aggregate throughput was capped at 110 Mbps (vs. the expected 400 Mbps for 4,000 sessions at 100 kbps each) and that hardware acceleration only aided SSL-encrypted traffic. Armed with Keysight’s findings, the IT team right-sized infrastructure, optimized gateway parameters, implemented split tunneling and capacity increases, and achieved better user experience and cost‑efficient provisioning.
