Scenarios where time is a factor in having a solution in place and up and running safely and securely. Where there are older devices that ordinarily wouldn't be up to the task of running modern apps and services. Where users need to work away from the network, and security is a concern.

It's best suited for a distributed remote workforce, securing internet access for users from anywhere. Suitable for highly regulated industries, such as banking and Healthcare. Not a good fit for an organisation where most of its legacy is in an on-premises environment. Bandwidth-intensive industries like media/entertainment firms.

Pros
Parallels
  • The printing driver is quite excellent, both in the Parallels Client and on the HTML5 client.
  • Setup is incredibly easy; the default setup is very functional, and adding features is a breeze.
  • Speed is very acceptable in general for end-users, the clients adapt quite well to the amount of bandwidth available, and features are available to adjust further.
  • Automation through PowerShell is great.
  • Support is usually quite fast and efficient.

  • Single Pane of Glass Management - Everything is very easy to access and monitor the entire environment from an internet security perspective.
  • Install Flexibility - We can and do install Zscaler Internet Access on both our client devices as well as our SD-WAN appliances and servers. This allows us to control internet security even on devices without an agent in our networks.

Cons
Parallels
  • Parallels Remote Application Server (Parallels RAS) continually improves the product but has broken some features recently. For example the web management portal lost the ability to manage user sessions after a major update. That issue was fixed in a later release
  • Multi-monitor support beyond 4 monitors (It does handle up to 4 -1080 monitors well)
  • More options around connection security and MFA. current options are sufficient but limited
  • We've noticed some performance issues with Windows Server 2019 and 2022. I'd like to see more robust support for remote applications running from those platforms.

  • The logs feel kind of lack luster
  • When issues are arising with SSL Inspection, logs show everything working despite end user experience
  • Could use some kind of global find functionality or something that would allow you to search the entire configuration for matching URLs and the like

We have been using Parallels since it was called 2X - it is a major part of how we do business. It is fairly simple to use and maintain - staff like it, we like it. It is a product that makes a promise - and it keeps it. As Parallels evolves, and clean bandwidth becomes more readily available everywhere - it just makes sense to continue to use Parallels in our environment

While Zscaler Internet Access (ZIA) delivers critical value in cloud security and RBI compliance, I rate renewal likelihood 7/10 due to evolving needs versus platform limitations. Below is my rationale:
Key Gaps:
1. Advanced Threat Costs:
ZIA’s add-ons (e.g., Advanced DLP, Sandboxing) incur 35%+ cost premiums – straining budgets as transaction volumes (UPI/iMobile) grow 50% YoY.
2. API Banking Scalability:
ZIA’s API rate limits throttle real-time policy sync during UPI peaks (10K+ TPS), forcing workarounds for finacle integrations.
3. RBI Future-Proofing:
Limited native support for upcoming digital rupee (CBDC) security rules requires custom development, increasing compliance overhead.

Usability
Parallels
Parallels RAS was easy to setup, with great admin guides and resources. We especially liked the included Visio templates which made diagramming much easier. The reference deployment diagrams also simplified our deployment process. Our end users love Parallels RAS. Apps launch faster than Citrix, and the Parallels RAS client is far more reliable than Workspace.

The application is easy to install and configure on all Windows devices. To troubleshoot any internet issue, we can easily collect all the relevant logs from Zscaler and check the exact issue. The only problem is with the uninstall, as a dedicated crew needs to provide the password.

Reliability and Availability
Parallels
If there are any issues with Parallels - they are usually more about the server operating systems than Parallels itself. It would be rare for us to have any reason to take Parallels offline - we schedule a reboot on the servers at 3am to keep the O/S itself fresh, but again - it is not a Parallels issue. If individual users have any issues we ask them to completely log out of parallels - which ends their session - and then back in - and that typically resolves the issue right away.

Performance
Parallels
I am giving Parallels 9/10 on this one because the only application that sometimes seems slow or has issues - is Microsoft Outlook. It is sometimes the result of a pop-up that may not show up in the published application (vs full desktop). Other than that - pages load very quickly - and it does not seem to slow down other applications that are running at the same time. Most of our users run Outlook, softphone and Teams locally - and published applications for everything else. When they do that - it is very solid.

Zscaler's ZIA support is quick and knowledgable. They respond within 1-2 hours of you submitting your ticket. They are very thorough and are typically ready to jump on a live troubleshooting session. Our ZIA platform and how we use is it unique so at times tickets can be open for weeks but we alway get quality support compared to other unrelated product support in our enterprise

Implementation Rating
Parallels
Overall, it was pretty simple compared to most other projects. Again, we had a strong familarity with the product so there was not much of a learning curve. Our 'biggest' issue is the end-user understanding of a 'local' application and a published application. For example - Online meetings need to run locally for camera/video to work smoothly so opening a link to a meeting from a published application continues to be an occasional issue.

We added our Integrated Services Staff to parallels, with filtered, published applications - in a single afternoon. We added licensing and installed the desktop client software on multiple platforms both in the office and at remote sites all on the same day - and got remote users that had never used the product up and running - very quickly.

  • Our customers have had dramatic cost decreases due to no longer needing IT departments to work with our software.
