Case Study: Aster Group achieves secure, zero‑trust remote access for 70% of users with Zscaler Private Access (Zscaler)

Delivering zero trust access for Aster Group UK with Zscaler Private Access

Aster Group is a UK not-for-dividend housing provider managing over 30,000 homes (£1.6bn in value) whose 1,400 IT users needed to work remotely. Their legacy Citrix Netscaler solution couldn’t keep up with a more mobile workforce and created friction for employees and third parties, while the IT team also faced server consolidation that required a simpler, more secure access model without placing remote users on the network.

After a PoC with partner Truststream, Aster adopted Zscaler Private Access (ZPA) to deliver zero‑trust, “inside‑out” connectivity that grants app‑level access (not network access) and hides application IPs. The cloud‑hosted rollout required no appliances, was completed three times faster than planned, onboarded four times more users than expected in the first month, and now secures about 70% of the workforce—improving user experience, reducing third‑party risk, simplifying datacenter consolidation, and accelerating cloud migration and DR/BCP plans.
