The quality of the support is fantastic.
Educational Technology Coordinator at a performing arts with 201-500 employees
We had promising discussions about resolving these issues, but no real action followed.
Network Administrator at a educational organization with 51-200 employees
They align the right people at the right time to solve our problems, providing focused support.
Chief Information Security Officer at Jubil
Most of the time, being fairly IT-savvy means most issues can be resolved internally, and when a ticket is opened, it's for something really complicated.
Systems administrator at PERSAN S.A.
The support team is excellent, and I would rate them nine out of ten.
Cyber security consultant at L&T Technology Services
The technical support for ZPA is excellent, rated ten out of ten.

We had regular calls, and the team was open and willing to assist us whenever required.

Senior Consultant Proxy Engineering at a financial services firm with 10,001+ employees
I would rate it a nine out of ten for scalability.
If I start seeing sluggishness or anything like that, I just reach out to my rep, and they connect with their dev team, typically resolving it the same day.
Educational Technology Coordinator at a performing arts with 201-500 employees
They declare an SLA regarding delays, making it a solid solution.
Network Security Manager at a computer software company with 201-500 employees
The solution is easy to scale for our use case and we have approximately 8,500 users working with it.
Chief Information Security Officer at Jubil
Zscaler ZPA has excellent scalability.

I rate the scalability of ZPA as ten out of ten because it's a cloud service and can scale as needed.
Technical management of Network Security - Network Hub at a comms service provider with 5,001-10,000 employees
We need to deploy it and ensure it will be available in two different Availability Zones, but it's not something that can be done with automation, such as auto-scaling.
DevOps Team Member at a computer software company with 201-500 employees

Educational Technology Coordinator at a performing arts with 201-500 employees
We've experienced zero downtime.
Head of Cybersecurity at SES Water
Our biggest problem with their service was it did not recognize the device despite our ClearPass sending information to the iboss box.
Network Administrator at a educational organization with 51-200 employees
Regarding pricing, Netskope is quite expensive, but when compared with other solutions, it's somehow justified because it has better categorization and more granular features regarding web protection, as it allows control of HTTP methods.
Systems administrator at PERSAN S.A.
Netskope has proven to be stable, which is reflected in my rating of nine out of ten.
Cyber security consultant at L&T Technology Services
Even during peak usage or mass remote access events, performance remains consistent, which is critical for an enterprise environment handling business-critical applications.
Senior Network Engineer at Anthology
The architecture uses a global mesh of service edges with built-in fault tolerance and redundancy, providing an always-on experience.
System Engineer at a retailer with 10,001+ employees
We implemented a resilient solution with load balance to ensure stability, which has proven effective thus far.
Solutions Architect at Direct Line Group
 

Room For Improvement

Iboss struggles with Mac support, ISP integration in India, and needs improvements in security features and cloud integration.
Users seek enhanced SaaS visibility, integration, features like identity protection, better pricing, support, policy management, and threat detection.
Zscaler Private Access needs scalability, flexible rules, better pricing, ease of configuration, vendor integration, and intuitive troubleshooting.
It is not as intuitive as the rest of the platform.
Head of Cybersecurity at SES Water
We also had a problem with a transition when we upgraded from one appliance of theirs to another, but their engineer lost a good deal of our data.
Network Administrator at a educational organization with 51-200 employees
Our iboss subscription access should be more secure with an OTP or VPN etc.
Specifically, the use of AI/ML for anomaly detection and dealing with signatureless advanced threats would be beneficial.
Senior Product Manager - Cyber Security for Middle East, Central Asia and Africa Region at Ivanti
There is a pressing need to expand this to 64,000 sessions.
Cyber security consultant at L&T Technology Services
It is important for the solution to correctly categorize websites as genuine or non-genuine, fitting them into the right category.
Chief Information Security Officer at Jubil
It complicates whitelisting, as we cannot determine which IP will be used, posing a challenge when needing to integrate with third parties.
Solutions Architect at Direct Line Group
I would appreciate seeing dynamic scaling implemented because it would be beneficial if an instance goes down to automatically start another one.
DevOps Team Member at a computer software company with 201-500 employees
While Zscaler Private Access (ZPA) wants users to utilize their infrastructure for scale benefits, regulated environments such as government and investment banks need on-premises processing for regulations and low latency requirements.
Sr. Cloud Security Architect at a tech services company with 11-50 employees
 

Setup Cost

Iboss offers competitive, transparent pricing with valuable cloud solutions, appealing to enterprises for predictable budgeting and desired functionality.
Netskope offers competitive pricing with significant value, generally including support, training, and is viable for enterprises seeking robust capabilities.
Zscaler Private Access offers premium, per-user pricing, justified by security features and cost-effectiveness within an 11-month payback period.
It offers the same features you would get from a vendor that charges 250,000 British pounds for a fraction of the price.
Head of Cybersecurity at SES Water
The following year, the cost of just licensing was similar to what was paid the previous year for a new appliance along with the implementation and licensing costs.
Network Administrator at a educational organization with 51-200 employees
Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern.
Managing Director
Netskope is cost-effective compared to similar solutions like Zscaler.
Senior Product Manager - Cyber Security for Middle East, Central Asia and Africa Region at Ivanti
It is expensive.
architect at Tata Consultancy
Although the solution is costly, its features justify the price for securing the organization from various access types.
Consultant at a consultancy with 10,001+ employees
While it is a premium investment, the short payback period of about 11 months and consolidation of multiple point products make it very cost-effective in the long run.
System Engineer at a retailer with 10,001+ employees

Head of Cybersecurity at SES Water
It's given us a lot more visibility into our computer assets that may be infected with viruses and also shows us people who have unusually large uploads or might be engaging in high-risk activities, such as searches or going to sites not categorized by their web crawler.
Educational Technology Coordinator at a performing arts with 201-500 employees
iboss was the best solution for us because, no matter what domain you were in, everything is under a single pane of glass, which is exactly what we wanted.
Managing Director
Netskope is cloud-native, enabling differentiation of tenants in cloud applications, whether they are enterprise or personal, and provides control over shadow IT access.
Network Security Manager at a computer software company with 201-500 employees
The threat protection capabilities are beneficial, especially in reducing the load on email traffic by preventing phishing emails and providing malware protection from advanced threats.
Senior Product Manager - Cyber Security for Middle East, Central Asia and Africa Region at Ivanti
Having these functionalities integrated into one dashboard makes Netskope efficient and user-friendly.
Cyber security consultant at L&T Technology Services
Zscaler pre-tests websites and authorizes safe access, giving us a layer of security that we rely on.
Solutions Architect at Direct Line Group
Zscaler Private Access (ZPA) is much more secure than VPN because users are only allowed to access specific applications rather than the whole network.
Technical management of Network Security - Network Hub at a comms service provider with 5,001-10,000 employees
Zscaler has allowed an easy, secure way for us to access our internal resources from outside.

Cloud gateway has strengthened remote web security and now needs better Mac and ISP support
The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

Provides secure remote access and web navigation protection with highly customizable features
The most helpful features in Netskope are the data loss prevention module, the anti-malware module, and the integration that it has with Information Rights Management from Microsoft. It has better categorization and more granular features regarding web protection, as it allows me to control HTTP methods. I can publish WhatsApp web for my users as read-only, for example. Other providers cannot; they are only on and off, and do not have the granularity for a website to be read-only. That comes with a downside, which is that they need to regularly update their controls to support those features in those websites.

Zero trust access has secured hybrid work and now provides seamless app connectivity
Zscaler Private Access (ZPA) has significantly reduced our attack surface by making our internal apps invisible to the internet. It effectively eliminates lateral movement as users are only connected to the specific application they are authorized to use rather than the entire network segment. Zscaler Private Access (ZPA) is highly stable. The architecture uses a global mesh of service edges with built-in fault tolerance and redundancy, providing an always-on experience that is far more reliable than our old hardware-based VPN concentrator. Zscaler Private Access (ZPA) is elastically scalable because it is a software-defined perimeter and not an appliance-based solution. I can instantly scale to support thousands of additional users without needing to upgrade any physical hardware.
