We had promising discussions about resolving these issues, but no real action followed.
Network Administrator at a educational organization with 51-200 employees
The product is reliable, making customer support less frequently needed.
Senior DevOps Expert at Telenor
I usually need to raise the alarm and contact a couple of people within Palo Alto Networks to just respond quicker, so technical support should be much better.
Director at PULSEC
We rarely need to contact support due to having a strong internal team and a robust product.
Senior Manager for Infrastructure at a computer software company with 5,001-10,000 employees
The technical support for ZPA is excellent, rated ten out of ten.
Technical management of Network Security - Network Hub at a comms service provider with 5,001-10,000 employees
We had regular calls, and the team was open and willing to assist us whenever required.
Solutions Architect at Direct Line Group
We lack specific root causes, and it's tough to relay information to users, considering multiple contributors such as phone numbers and internet service providers.

They are also able to meet on-demand requirements based on your contract with them, and can easily provide adequate resources and scalability.
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
To scale, one would need to upgrade or acquire more hardware.

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

Room For Improvement

Iboss struggles with Mac support, ISP integration in India, and needs improvements in security features and cloud integration.
Prisma Access needs better UI, integration, custom application support, pricing, documentation, global presence, and technical support enhancements.
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.
Hosting it in the cloud can mitigate these issues by allowing connection through the nearest Palo Alto or Prisma Cloud regional hub.
Senior Manager for Infrastructure at a computer software company with 5,001-10,000 employees
There is a lack of integration with third-party solutions like CrowdStrike or SentinelOne in Prisma Access by Palo Alto Networks.

Sometimes a third-party outage could impact the whole operability.
Network and Cybersecurity Consultant at a tech services company with 11-50 employees
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.
Prisma Access is costly but valued for its comprehensive security, with room for pricing and licensing flexibility improvement.
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
The pricing is on the higher side, rating it around eight to nine out of ten.
Senior DevOps Expert at Telenor
From my experience, Palo Alto is more expensive compared to solutions like Netskope and Triscale.
Security Engineer at a tech services company with 1,001-5,000 employees
Pricing for Prisma Access and Prisma SD WAN is high due to the need for different hardware flavors like IONs.
Senior Manager for Infrastructure at a computer software company with 5,001-10,000 employees
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
 

Valuable Features

Iboss provides comprehensive cloud security with advanced features, enhancing data protection and management efficiency for network security.
Prisma Access provides scalable, secure cloud-based VPN access, real-time threat prevention, and integrates seamlessly with existing infrastructures.
Zscaler Private Access offers secure, scalable app access with Zero Trust, enhancing security and flexibility, especially in cloud environments.
The solution's mental health function can detect if someone needs help.
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
These features are security-driven, providing robust protection against increasing cyber threats by integrating NG Firewalls, SD WAN, and CASB, all within a fully cloud-native solution.
Senior DevOps Expert at Telenor
GlobalProtect has been beneficial for its cloud security capabilities, which are vital as businesses seek hybrid options and need to support remote workers while addressing latency issues.
Senior Manager for Infrastructure at a computer software company with 5,001-10,000 employees
One of the most valuable features of Prisma Access by Palo Alto Networks is the ability to manage on-premise firewalls.

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.

Zscaler has allowed an easy, secure way for us to access our internal resources from outside.
DevOps Team Member at a computer software company with 201-500 employees

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.

Zero-trust access has improved remote security and now simplifies cloud-based firewall management
Regarding the integration part for Prisma Access by Palo Alto Networks, the integration with identity providers is pretty much good. It is basically firewall as a service, so it performs well. I completed the integration without any issues. What Palo Alto Networks can do better for Prisma Access by Palo Alto Networks is probably to have the point of presence available in more locations. The point of presence from the Serbia region has the nearest POP in Frankfurt, which is an issue since it is your gateway—when you start browsing the internet, you go through a commercial connection in Germany. They definitely need to spread the service in other countries.

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.
