Software Engineer Telecommunications Used the software for: 1-2 years ### "zscaler, once configured correctly, makes vpn and internet access seamless" September 14, 2024 4.0 Pros Private Access and Internet Security -- once configured and working -- works in the background with no user intervention. I can simply turn on my laptop, and be able to automatically VPN into my company. Cons Many false positives and access blocked when zscaler was first introduced at our company. It took a while & after about 9 months, most of the issues were resolved. Switched from [Junos Pulse](https://www.capterra.com/p/125108/Junos-Pulse/) zscaler was in the shortlist of vendors and won after a selection process Review Source TM Terry M. Senior Analyst Mining & Metals Used the software for: 2+ years ### "nightmare software for coders dealing with internet" May 8, 2025 1.0 Pros similar user interface to the old company proxy ivanti that we used, authentication is simpler than ivanti Cons zscaler hijacked the proxy channel which makes a lot of operation computers in trouble as they cannot configure corporate proxy for softwares to works. it does not allow corporate vpn toggle on and off, can only wait for authentication to expire Switched from [Ivanti Connect Secure](https://www.capterra.com/p/147283/Connect-Secure/) the cost is lower for zscaler and zscaler also has more cybersecurity function but obviously it was a mistake Review Source VR Verified Reviewer Network Engineer Information Technology and Services Used the software for: 1-2 years ### "Zscaler is great solution when it comes to detect/prevent the thread within the cloud." May 15, 2022 5.0 Overall Zscaler has brought the new generation in network security, and Zscaler made the other Security vendors to think in the different directions compare with thinking in traditional way. Zscaler kind of removed the network latency problems with traditional VPN solutions here Zscaler POP presence really helped. Pros This is one of the best solution I have worked with, it provides the seamless experience better than the traditional VPN solutions. Connectivity speed is faster comparatively than the VPN solutions because of closer Zscaler POP availability. With speed you are also sure that you are sitting in Secure environment. As Zscaler also makes it sure no threats are touching the endpoint as well even the Zero day threats are detected and prevented within the Zscaler cloud. Cons I had few problems with Zscaler ZPA solution, unable to resolve the DNS for private web. However all this got resolved as our team had worked with Zscaler support team. Alternatives considered [Cisco AnyConnect](https://www.capterra.com/p/169495/VPN-and-Endpoint-Security-Clients/)[GlobalProtect](https://www.capterra.com/p/234123/GlobalProtect/) Reason for choosing Zscaler Zscaler overall has great features and better market review. Switched from [GlobalProtect](https://www.capterra.com/p/234123/GlobalProtect/) With Global Protect needed to manage the overall Security infrastructure, like managing the firewalls, managing the lifecycle of the product is really a heavy job. With Zscaler you are not managing the Hardware Lifecycle this makes the life bit easier.

We are in the process of doing the full company rollout, but we have a lot of users and this really helps us get visibility and security around our networked resources. Pros I love that I don't have to use multiple VPNs to get to various parts of my company and product. Having Zscaler handle that all is really nice. Logging into SIEM is a lot, but good information and great for investigation. Love the agent. Works great for Windows and Mac Cons Linux integration is in beta and I'm hoping it gets better. Setting up can be tricky, but professional services make it worth it. Alternatives considered [Perimeter 81](https://www.capterra.com/p/166731/Perimeter-81/) Reason for choosing Zscaler Better vetted, good support and similar companies like ours have implemented it and had great success.

It's one of those tools that quietly does the heavy lifting behind the scenes, keeping everything secure without slowing things down. Pros Zscalar just quitely does it's job without making a fuss. I don't have to thing about VPNs or worry about something is secure or not, it handel's everything in background. It is fast and make my remote working feel effortless. Cons I found that it is having connectivity issue when switching network or location. Sometimes it feels like it's a bit too protective and I end up getting blocked from some site that I actually need. Review Source AB Adir B. CISO Health, Wellness and Fitness Used the software for: 2+ years ### "Great Tool and soualtion" May 5, 2025 5.0 Pros True Zero Trust Network Access (ZTNA) What’s liked: Zscaler provides a zero trust architecture that grants access only after identity and context verification—without exposing apps to the internet. Benefit: Reduces lateral movement risk and limits attack surface, especially valuable for protecting sensitive GxP systems, R&D environments, or partner access. From your lens: Enables secure remote access to internal systems (e.g., SAP, lab tools) without relying on legacy VPNs or DMZs. Cons Complex Initial Configuration and Learning Curve What’s least liked: The policy engine and access configurations can be complex to design and implement correctly, especially in hybrid environments with legacy systems.

Social Worker Hospital & Health Care Used the software for: Less than 6 months ### "social worker" October 15, 2025 5.0 I have been using it for a few months now and haven't had any issues. I used to use Crisco Anywhere, but recently we moved to using Zscalar Pros I never get kicked off while working remote. It's easy and quick to log on to. It's really a trusted network. Cons I have to authenticate numerous platforms I need to log into remotely, but only at first. Once you authenticate each one then I don't have to do it again until I log out and log back in. Review Source Stephanie A. Tech Advisor Airlines/Aviation Used the software for: 1-2 years ### "Zscaler keeps us moving" March 28, 2024 5.0 We went from a VPN application that required users to reauthenticate every 10 hours on a mobile device and every 4 hours on a laptop for security reason, to Zscaler that we can allow users to reauthenticate every 30 days on mobile devices and every 3 days on laptops. The user experience has been improved tremendously. Additionally, the connectivity is more stable using Zscaler versus our previous application. Pros Zscaler gives more security for the organization, while giving users more privacy. Analytics are hands down the best we have used. 10k+ users and we have had little to no problems since deploying Zscaler. Having the flexibility to change the duration for authentication while still maintaining a secure environment has made this tool a game changer for our users. Cons Users initially had some confusion about the tool disabling when they were on a trusted network. Time and usage has helped to clear the confusion. Review Source Nachiket P. Data Analytics Associate Management Consulting Used the software for: 6-12 months ### "ZScaler - The best application for Internet security" March 27, 2022 5.0 Zscaler helps me browse the internet safely, without having me worry whether a particular website may be malicious or not. It has helped me prevent data loss and data theft due to the blacklisting of potentially dangerous websites and also provided me warnings in case of suspicious websites. Pros The best thing about Zscaler is that it performs it works efficiently in the backend without providing me with too many notifications. I get immediate reminders if I end up browsing an unsafe website and it also blocks access to websites blacklisted by ZS, thus preventing data theft. Cons There is nothing I dislike about the software. The only recommendation would be to enhance the UI to make it look more professional, maybe like that of Avira or Kaspersky Review Source AD Alper D. LDI Environmental Services Used the software for: 6-12 months ### "If security is important, zscaler comes first " January 4, 2025 5.0 I can easily log in, stop and restart easily. Pros Zscaler usage is so easy, I can open easily. Cons Usage is so easy so I cannot say anything bad. Review Source UG Utkarsh G. Administrator Information Technology and Services Used the software for: 1-2 years ### "Reliable securities by Zscaler" January 25, 2023 5.0 Overall experience is good Pros Reliability is most important thing in terms of security.Zscaler is very reliable in terms of it, efficiently monitors if there is any vulnerability and suddenly triggers alerts, much effective software Cons As far as I am using it, there is nothing I like least about it. Review Source KK Kristin K. Call Quality Insurance Used the software for: 6-12 months ### "Great for the end user!" November 6, 2021 5.0 Overall, this is a great product! I would highly recommend this product from a End User stand point, super easy and very fast. I do not have anything to list for recommendations, I give this a 10/10 for ease of use and 10/10 for product satisfaction! Pros This is such an easy product for the end user, I have been using this for about 1 year to access our secure network and it even links right up with Duo Mobile! which makes getting logged in! As the end user you get a notice on the computer that you need to re-authenticate your connection- select authenticate and you get a notice right to your phone, accept or deny- accept and BAM you are in! that fast and that easy. Cons The only con that I can think of is how often I have to get logged in, this is likely a security setting that our IT team has access to but as a end user it is a little troublesome if you are mid-day and then have to go through the process of re-authenticating- its fast but the smallest thing can throw off a whole day Review Source WZ Winnie Z. Designer Civil Engineering Used the software for: 6-12 months ### "Zscaler VPN" December 14, 2022 5.0 Excellent software, replaces Cisco VPN which required log in everytime. Zscaler is seamless and very user friendly Pros Our company recently implemented Zscaler for the VPN and it has been a great experience so far. It is easy to use, does not require log in everytime you open your laptop, unlike Cisco VPN and it is much, much faster. Installation and implementation was very smooth and there were no major issues Cons The only issue we had was due to people connecting to the old Cisco VPN still, which caused issues with Zscaler. However that is a user issue and not really due to the software Review Source PM Patrick M. Sales Engineer Electrical/Electronic Manufacturing Used the software for: 6-12 months ### "Functional " November 16, 2023 5.0 Pros Zscaler is intuitive to set up and maintains VPN status while traveling and switching networks. Cons Re authentication of the app is required from time to time however it is a quick and simple process. Review Source LN Lisa N. President CEO Computer & Network Security Used the software for: Less than 6 months ### "ZScaler is a USER installation - difficult to maintain when multiple users login a device" September 2, 2021 4.0 support was good; functionality was good but high maintenance for management of false positives. Pros cloud based firewall on the endpoint device - protection no matter where they were working Cons user based installation... so when you have multiple users logging into the device very hard to keep maintained. We need to protect the device no matter who logs in. Review Source VR Verified Reviewer Software Developer Team Lead Insurance Used the software for: 1-2 years ### "I left a job I loved because of ZScaler" January 21, 2021 1.0 Let me start by describing what ZScaler is at its heart: a cloud-based network proxy that uses its own root certificate to inspect TLS/SSL traffic. If you are a company in the business of making software, keep this product away from your software developers. Far, far away. It does not play nice with many software development tools, even once you go through the pain of adding their root certificate in all the right places. I have spent hours and even days interacting with ZScaler support, often with no solution ever found. After spending months fighting frequent issues that came up, I finally threw my hands in the air and left my company. It probably works fine if you're just doing "regular" stuff with your network, like browsing, file uploads/downlads, etc. If you're doing anything more advanced, keep away from ZScaler. Pros \- Provides competent security and access for basic computing - macOS app works alright, although it does have plenty of hiccups Cons \- Hard to get it to work right with software development tools. In some cases, no proper solution was ever found. - Support is incredibly terrible. Unhelpful and wastes a lot of time. I really can't emphasize enough how frustrating the support was. I ended up just finding my own workarounds 90% of the time, after spending hours and hours on the line with support. - Adds latency, which can make profiling network operations difficult. - Sometimes you run into websites randomly blocking you or asking for CAPTCHA due to routing through ZScaler gateways.

Pros Il software, utilizzato in ambiente corporate, agisce senza che venga richiesto niente all'utente, si mantiene aggiornato da problemi e vulnerabilità in maniera conforme a quanto deciso a livello di infrastruttura IT Cons Avrei gradito una comunicazione sulla limitazione del traffico sulla vpn che utilizzavo, per poter capire cosa stesse succedendo. Inoltre le policy vanno aggiornate manualmente e sarebbe più funzionale de fosse automatico Review Source VR Verified Reviewer Data & Reporting Analyst Pharmaceuticals Used the software for: 1-2 years ### "ZScaler review" May 24, 2022 5.0 Pros Cloud and security protections to beef up your company's infrastructure with less costs.

It supports a lot of use cases. Zscaler offers protection to users' internet traffic, protects private application access, and secures cloud transactions.It can Integrate with a lot of products as per the need like we can Integrate it with siem solution for exporting logs, or can integrate with IDPs to authenticate users. Advanced threat protection modules are quite good, and provide granular controls over SASE applications. The policy applies in real time which is a very good thing. Cons No, I didn't find as of now to dislike about anything as of now. Review Source UR Umang R.

IT Business Analyst Chemicals Used the software for: 1-2 years ### "Enhanced protection in the cloud world thanks to Zscaler" February 21, 2022 4.0 Pros The majority of business users are only interested in not getting any viruses on the PCs or mobile devices. They aren't interested in the way how we are protected from various cyber threats - Zscaler is the perfect solution as it gives us the wanted protection without the need of any user intervention - it works in the background while we perform our daily tasks. I was really amazed by the pace of how ZScaler detects potential vulnerabilities and possible cyber attacks. Cons ZScaler can be costly when thinking about using it in big enterprises.

Pros zscaler Internet Security and Zscaler ZAPP access gives more control over devices in organziation that connects to internet. we can control what ip and what websites that devices go out via internet and we have control over protocols and ports channels that devices communicate on the internet Cons More control over zapp access like internal application access Reason for choosing Zscaler cost and more control and security Review Source CL Chris L.
