It's easy to roll out, and their understanding of our business made it seamless

One aspect we value about iboss is its simplicity. Their customer service is brilliant, and they are super responsive and knowledgeable. It's easy to roll out, and their understanding of our business made it seamless. We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times. The user interface is highly intuitive. Our IT team picked it up with minimal training. It's arranged so that it's easy to find where things are. Another advantage is the single pane of glass console, which gives you visibility into what's happening. We're not fully there yet because we haven't implemented zero trust, but we're excited about the possibilities from the demos we've seen. We launched a POC of iboss' ChatGPT Risk Protection feature two weeks ago. AI is a great tool, but you need to be careful what you put into it. My biggest fear is employees inputting sensitive corporate information or customer PII data into one of these chatbots. I was impressed by our trial of the feature. It's exactly what we wanted. Now, when a user goes to ChatGPT, there's a banner warning them not to share information, and we can block conversations containing customer data like bank details and email addresses. I don't want to stop people from using it, but we need visibility. We've only tried it on a test group of 15 people. You can configure it to look for specific keywords or integrate it with your DLP policy if you have that configured

Cloud-based platform simplifies device and data center management

I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."

"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."

"The security aspect of the solution, particularly the malware behind it, is excellent. That's something that really helped us out. It's not just a simple proxy that just blocks the insights of potential threats that come on behind it. They do malware detection and that helps us a lot."

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."

"iboss is among the few products providing inline filtering where no application is needed on the device."

"iboss is easy to use despite its complexity. Multiple engineers manage it, but it's significantly more straightforward to administer than traditional VPNs and web proxies."

"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."

More iboss pros

"This solution provides a DLP on the cloud and very few people have a scanning device for data at rest."

"The most valuable feature is the zero-trust part of this solution."

"It's quite reliable and performs well for users."

"Palo Alto Firewall is one of the best firewalls in the world."

"The scalability of the solution is excellent."

"We have an application called ADEM that helps us troubleshoot network-related issues. It helps us to isolate an issue whether it is on the ISP level, endpoint level, or system access level."

"The solution also provides traffic analysis, threat prevention, URL filtering, and segmentation. That combination is important because it enhances the protection and makes the traffic more secure. It also keeps things more up-to-date, enabling us to deal with more of the current threats."

"Being able to use the user ID or Active Directory Group is one of the great features for control and providing more flexibility without worrying about IP addresses."

More Prisma Access by Palo Alto Networks pros

"Users get direct secure access to applications over the internet."

"Overall, the solution does a pretty good job at web filtering."

"I find all Zscaler Private Access features valuable because each replaces flawed technologies, such as EPAs being replacements for VPN and PR as a replacement for PAM, so I can't mention only one valuable feature. Overall, Zscaler Private Access is a good solution."

"The UI is easy to use."

"As a cloud-based service, it is very easily implemented."

"The customer service and support are very good."

"The VPN is great for the stability on offer and for the cloud updates and insights you can get."

"The product provides a seamless user experience."

More Zscaler Zero Trust Exchange Platform pros

Cons

"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."

"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

"The reporting feature needs improvement."

"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."

"Our iboss subscription access should be more secure with an OTP or VPN etc. It is easy to gain access if, for example, hackers obtain my username and password."

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."

More iboss cons

"When we deploy firewall rules via Panorama, we find it's a little bit slow. We have a global environment and might have 100 gateways or VPNs in the cloud. When we deploy something, it tries to deploy it one-by-one, and that can be slow."

"It is a managed firewall. When you run into issues and have to troubleshoot, there is a fair amount of restriction. You run into a couple of restrictions where you don't have any visibility on what is happening on the Palo Alto managed infrastructure, and you need to get on a call to get technical assistance from Palo Alto's technical support. You have to get them to work with you to fix the problem. I would definitely like them to work on the visibility into what happens inside Palo Alto's infrastructure. It is not about getting our hands onto their infrastructure to do troubleshooting or fixing problems; it is just about getting more visibility. This will help us in guiding technical support folks to the area where they need to work."

"The user interface could be better. They need to work a little bit on the console. It is similar to their firewalls but not exactly. They need to clean it up a bit."

"The one thing that I've been a little bit disappointed with is when we have had to open cases with Palo Alto about Prisma Access issues. Versus their other platforms, like their firewalls, where we tend to get really quick responses and very definitive answers, the few tickets I've had to open for Prisma Access have taken them longer to respond to. And they haven't necessarily given me the kind of answer I was looking for, meaning a fix to the problem."

"It applies commits to the firewalls slowly. There isn't an API you can use for anything. We've previously had trouble with the egress IP addresses though we expressed to engineering that those mustn't change. They changed several times without warning, causing a lot of headaches."

"One thing that would help is if we could get a guide. With Cisco, for example, you can just type the problem regarding your Cisco product and you will easily get your solution. In Palo Alto, however, it's not easy to find the solutions."

"They automatically update and they should give us time to fully understand what they're updating so that we can make sure it doesn't impact production."

"The initial support team is not very good. Most of the time, I have found that they are one to three years experienced only. They don't have network expertise. They know about Palo Alto products but don't know how to troubleshoot the issues. We have to guide them most of the time to troubleshoot correctly since their approach is not developed."

More Prisma Access by Palo Alto Networks cons

"They should work on a replica account. There could be alerts and replica files sent to the DLP team during data collection."

"What could be improved in Zscaler Private Access is its notification. For example, if there's a speed issue, there should be a pop-up that alerts the user about it. If there is a network quality issue, for example, it isn't good enough to connect to, or the network quality is bad, there should be a notification from the solution. Zscaler Private Access also needs improvement in terms of its interface and security."

"The granularity in blocking is not sufficient, as new domains are automatically blocked for 30 days without further information."

"We faced certain migration and implementation challenges in executing the tasks, so I would suggest improvement related to the stability of the solution."

"SCMP support would be one of the biggest improvements in my opinion. More speed improvements are also required."

"It would be better if the Zscaler Private Access team made it easier for people to find subscriptions on the portal, mainly information on what my customers subscribed to or the type of licenses purchased."

"The product is not reliable."

"We would like to extend the SASE applications for Zscaler."

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."

"It is expensive compared to one of its competitors."

"We had the cost of purchasing a new appliance along with the implementation and licensing costs. However, 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."

"It is not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"The overall pricing for iboss is very competitive and transparent."

"The pricing can be difficult because it came to us with another agreement, but it can be negotiated. I highly recommend people to compare this product's performance and pricing against BetterCloud, because I feel BetterCloud is better than Prisma SaaS if they're starting from scratch."

"The solution is expensive."

"The licensing cost is about 18,000 euros."

"The pricing is very friendly. It's not confusing to figure out your workload and how much you'd be paying for the solution."

"The licensing model for this product is complicated and changes all the time, making it very hard for the user to comprehend the configuration."

"Palo Alto is the Cadillac solution, so their products are pretty expensive. That's just the way it is. Their solution surpasses anything else. Cisco AnyConnect, Zscaler, and all of the other products don't compare. Palo Alto is the market leader with the most features. It saves you work, and you don't have to worry about it."

"Prisma Access is a little bit expensive."

"Prisma Access is one of the best compared to other products on the market. The cost is favorable, and Palo Alto provides a simple architecture, so I recommend the solution to anyone using a different product. There are no hidden costs besides the license; what you see is what you get."

More Prisma Access by Palo Alto Networks pricing and cost advice

"The licensing model for Zscaler Cloud DLP allows you to only buy what you need. You don't need to buy it as a whole, so it's good."

"The solution is expensive."

"Zscaler SASE software is quite expensive compared to other solutions"

"It has been relatively reasonable for what it does. Some of the additional license costs based on the advanced next-generation firewall functions are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Overall, the cost seems reasonable."

"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."

"The cost is expensive. It depends on the number of users."

"Zscaler Private Access is extremely expensive."

"It's an affordable solution"

Reviews from Real Users

Below are some reviews and helpful feedback written by Microsoft Azure Synapse Analytics

users who are currently using the solution.

PeerSpot user Partha D., Global Network Tech Lead at a computer software company, speaks about his experience using the product, saying, "It protects all app traffic so that users can gain access to all apps. Unlike other solutions that only work from ports 80 and 443, which are predominantly for web traffic, Prisma Access covers all protocols and works on all traffic patterns... The most sophisticated attacks can arise from sources that are not behind 80/443."

Tejas J., a Sr. Cloud Security Architect at a computer software company, mentions that "it is geographically dispersed, and it sits on top of Google and AWS platforms. Therefore, you don't face the standard issues, such as latency or bandwidth issues, that you usually face in the case of on-prem data centers.”

Another PeerSpot reviewer, Max I., Associate Director at Cognizant, comments that "Security is absolutely spot-on, really top-notch. It's the result of all the components that come together, such as the HIP [Host Information Profile] and components like Forcepoint, providing end-user content inspection, and antivirus. It incorporates DLP features and that's fantastic because Prisma Access makes sure that all of the essential prerequisites are in place before a user can log in or can be tunneled into."
