What is Zscaler Private Access?

Zscaler Private Access (ZPA) is a cloud service from Zscaler that provides zero trust access to private applications running on public cloud or within the data center. With ZPA, applications are never exposed to the internet, making them completely invisible to unauthorized users. The service enables the applications to connect to users via inside-out connectivity versus extending the network to them. Users are never placed on the network. This zero trust network access (ZTNA) approach supports both managed and unmanaged devices and any private application (not just web apps).

Zscaler Private Access Features

  • Supported: Fast, uninterrupted access to private applications
  • Supported: Security by reducing the attack surface and preventing lateral movement
  • Supported: Superior digital experiences

Zscaler Private Access is used for our entire network of several thousand staff, both in-office and remote. Our first encounter with the product around the time of the pandemic was less than stellar. There were all kinds of hiccups in connecting and annoying extra steps to take, whether in office or remote. It seemed to interrupt the workflow too frequently.<br><br>But as time went on, these errors were less and less frequent, and today the use, at least for me personally, is very smooth, and I no longer hear complaints from colleagues. Zscaler continues to improve and make connections easier, whether to my iMac or to my account on my phone. Verification is now very easy and consistent. <br><br>Since I don't work in IT, and I work remotely, I can't give a full evaluation of the software from a perspective of implementaion. I don't know if the issues we had initially were the result of failures to adequately set up the system, or if they were on the part of Zscaler itself, or both. But as of now I have no complaints, and I no longer hear complaints from colleagues.
  • Quick verification via phone.
  • Reminders for reauthentication.
  • Reminders for chaning passwords.
  • No noticeable loss of connection speed.
  • Initial setup might be difficult.
  • Greater communication of upcoming changes.
  • Better instruction when a new process is initiated for verification.
I work for a large company with many different offices and remote staff as well. All have to use zscaler to access any sites on our network. Zscaler is appropriate for enterprise-level IT setups. I can't see recommending this to a small company, but then I am not well versed in what options Zscaler might offer to smaller companies.

After Covid and increase in Work from home scenario, our systems are fortified with ZScaler security. If I am right, it is used across Genpact as a preferred way to keep our data safe.
What it does is that it creates that additional layer of security over your ISP. Either the users use a Mobile hotspot or they are directly connected via broadband. In either case, the security is lesser compared to the secure line in the office. In order to compensate for that, ZScaler secures the systems of the employees.
In simple terms, it is like connecting to a secure VPN and connecting to internet via that. A couple of things what ZScaler does is:
1) Secure the data
2) Prohibits access to unsecure websites
3) Regulates the Operating system
4) Adds that additional layer of security while connecting to internet.
5) For the most part, blocks spam and phishing attempts. I say most because there are new ways invented every second to hack someone's data, identity and money.
  • Security of data
  • Control over websites
  • Sort of secure VPN
  • Easy connection to office intranet even while working from home
  • Secure internet
  • Internet Speed
  • End user can potentially close it.
Well Suited:
- Work from home scenario
- While working with confidential data
- While working with financial data
- Office intranet

Less Suited:
- Reduces internet speed
- If the user gets a password, can exit/close the app.
  • Data privacy
  • Data Security
  • Safety of Personal Identifiable Information
  • Maintaining system control on WAN
  • Safety of Client's data
  • Safety of Genpact's data
  • Safety of individuals

Deployed the ZPA for the whole organization to replace the legacy remote VPN solutions for internal organizations app. Zscaler private access, as the name, suggest help using the private applications within the organization. With ZPA we have addressed the latency issues which were associated with legacy remote VPN solutions. ZPA also helped in better access control for authorized users, not everyone had full access (as with the remote VPN solution), instead only required access to applications for the required work profile.
  • Access control for overall organization, follows the ZTNA model.
  • Better speed for remote users compared with legacy remote solutions.
  • Better visibility on ZScaler portal, thus better control from central space.
  • Due to its function, ZPA does not allow to see private IPs, which makes IT admin life bit harder.
  • Performance always has a room to be improved.
  • Would be great if more documentation is available to understand the model.
ZPA is a good solution if someone is looking to deploy the Zero Trust Network Architecture (ZTNA), as it is currently industry's best practice. If you have data centre in Cloud Exchange this may be a really good solution.
However, if you want to secure your application by yourself, the physical firewall is really a good solution as well, you will have better control and full access to the network, such as you can see the private IPs (which is not possible with ZPA).
  • Internal Network Access for employees.
  • Better control on access for different employees, or contractor roles.
  • Performance and Analytics provided by Zscaler dashboard.
  • Overall positive Impact.
Well ZPA is a good solution, however everyone has their own advantage and disadvantages, with ZPA you can deploy ZTNA model, which will help you better control on access, however Palo Alto, Fortinet they are also market leading firewall solution, and you can not deny if they are not providing the same features.

During the pandemic, we had to implement a new VPN solution because our original one could not handle the load of so many more people working remotely. We now use Zscaler as our primary VPN tool because it is able to handle a large number of users and is much easier to use than our previous solution. It is a must for me because I have worked remotely for my company even before the pandemic.
  • Supports a large number of concurrent users
  • Runs in the background
  • Handles both VPN and security
  • Sometimes the interface crashes and I need to kill it and restart
  • It can unintentionally block some services like dropbox
  • I don't get a notification when I need to re-authenticate
I need to get on VPN every time I use my computer so Zscaler is nice because it loads quickly with Windows and is completely in the background. You can turn it on and off as needed through the user interface and is able to connect very quickly (I'm a couple of states away from the server I log into). It's nice that you can enable/disable the VPN connection and firewall separately.
  • Fast VPN access
  • Ability to handle a large number of users
  • Administration tools for management
  • The business was able to run with everyone working remotely
  • We consolidated into one tool for VPN and internet security
  • Less downtime spent configuring and connecting with the tool
We originally used Cisco AnyConnect but when the pandemic hit and everyone started working remotely the Cisco VPN just couldn't handle the massive increase in users. The connection was unreliable both inability to connect and stay connected. It also seemed to include a lot more time manually connecting to the service rather than handling everything automatically behind the scenes.

Zscaler Private Access is used company-wide across the globe. Of course, the secure access to any application is being provided by this software.
  • Being cloud based does not require individual licensing.
  • Reliable for accessing the app.
  • Security from threats of the always connected world.
  • Costs for a small company.
  • Improvement in the admin interface.
For a big company, this is obviously a must-have solution for secure and reliable access to apps. However, it may not be suitable for small companies due to cost.
  • ROI will be there considering the Low IT infra requirement.
  • Scalable can be upgraded.
  • No individual licensing.
Both are good but sometimes relationship and cost is the factor to decide the final vendor.
