What is Zscaler VPN called?

Zscaler Private Access or ZPA

Understanding the alternative name for enterprise security platforms helps organizations transition away from legacy infrastructure safely. Exploring modern connectivity options prevents network vulnerabilities and enhances overall workforce protection.

The Short Answer: What is Zscaler VPN Called?

If you are just looking for the application name to connect to your corporate network, Zscalers modern alternative to a traditional VPN is called Zscaler Private Access (ZPA)[/b]. The actual software application installed on your laptop or mobile device to run this service is called the Zscaler Client Connector.

Most users simply want to know what to click to check their email remotely. But there is one counterintuitive security vulnerability with traditional VPNs that 90% of organizations overlook - I will explain exactly how the ZPA architecture completely neutralizes it in the Zero Trust section below.

Why Zscaler Private Access Isn't Actually a VPN

Lets be honest - calling ZPA a VPN is technically incorrect. Traditional VPNs create an encrypted tunnel that places you directly onto the corporate network. Once you are in, you can typically see everything. This is dangerous.

Industry estimates suggest legacy VPN vulnerabilities account for roughly 30-40% of remote access security breaches. In reality, handing out network-level access is like giving someone the master key to your entire office building just so they can use one specific printer.

Zscaler Private Access uses a Zero Trust Network Access (ZTNA) model instead. It connects users directly to specific authorized apps, never to the network itself. Staring at a network map trying to secure 50 different VPN endpoints used to give me massive headaches. The ZTNA approach completely eliminated that stress because the network is effectively invisible to the end user.

Game over for lateral movement.

Clearing Up the Naming Confusion

I have seen countless IT tickets where users confuse the different Zscaler products. It took me three weeks of trial and error during my first deployment to fully grasp the product boundaries.

Zscaler Internet Access (ZIA) secures your general web browsing and SaaS traffic against external threats. Zscaler Private Access (ZPA) is strictly for accessing your companys private, internal applications securely. The Zscaler Client Connector is the single lightweight software agent running on your endpoint device that routes traffic to both ZIA and ZPA.

The Architecture Shift: Zero Trust Network Access

Here is that critical security vulnerability I mentioned earlier: traditional VPNs expose your IP address to the public internet. They have to, or you could not connect to them. ZPA flips this entirely.

With ZPA, the applications establish outbound connections to the Zscaler cloud. Your internal network firewalls block all inbound traffic. You heard that right. The applications are completely hidden from the internet. Hackers cannot attack what they cannot see.

Wait a second.

Does this cause latency? Typically, no. In many production deployments, users usually experience performance improvements ranging from 15-25% because ZPA routes traffic through Zscalers massive global edge network rather than backhauling it through a central corporate data center.

Why Legacy VPNs are Dying

Conventional wisdom says you just need more VPN concentrators to handle remote work. After watching companies waste hundreds of thousands of dollars scaling legacy hardware, I completely disagree. Adding more VPN capacity just scales your security risks.

The modern workforce is mobile, and applications live in the cloud. Forcing all that traffic back through a legacy VPN appliance is a bottleneck that frustrates users and overloads infrastructure.

Understanding the Zscaler Ecosystem vs Legacy VPNs

Traditional VPN

Often sluggish due to traffic backhauling and requires manual connection steps

Network-centric - grants broad access to the entire corporate network once authenticated

Legacy environments that have not yet migrated to cloud services

Exposes inbound listening ports to the public internet, creating an attack surface

Zscaler Private Access (ZPA)

Seamless, always-on connection operating quietly in the background

App-centric (ZTNA) - grants access only to specific authorized applications

Secure remote access to private internal applications across hybrid environments

Applications are completely invisible to the internet with outbound-only connections

Zscaler Internet Access (ZIA)

Fast, local internet breakouts through global edge nodes

Secure web gateway providing threat protection and data loss prevention

Securing general outbound internet traffic and SaaS application usage

Inspects SSL traffic for malware without slowing down user browsing

Remote Access Architecture Overhaul

TechFlow, a mid-sized software company, faced severe latency issues in early 2026. Their 400 remote employees complained daily about connection drops when using the legacy VPN. The IT team was exhausted, fielding dozens of tickets every single morning.

Their first attempt was upgrading their physical VPN hardware. But the issue persisted - the central firewall simply could not inspect encrypted traffic fast enough. Employees started bypassing the VPN entirely, creating massive security blind spots.

At 2 AM on a Tuesday, rubbing my burning eyes while looking at bandwidth logs, the realization hit. We were routing all internet traffic through our data center just to inspect it. We ripped out the VPN and deployed Zscaler Private Access alongside ZIA.

After a rough two-week transition where we had to map out every single internal application, the complaints stopped. Connection speeds improved noticeably, and helpdesk tickets regarding remote access dropped by 75% within the first month.
