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

Have supported client adoption of security solutions but need more control over infrastructure
It's a working solution. It's not the easiest, but no DLP solution is easy. With Netskope, the whole infrastructure is proprietary. Prisma Access by Palo Alto Networks is using a service in AWS, and it's not totally a proprietary infrastructure. Sometimes a third-party outage could impact the whole operability. I'm not certain if the vendor is moving towards sovereignty of infrastructure at this moment, but from what I saw in the past, there was this reliance on third parties for the infrastructure: AWS, GCP, Oracle, and others. This is one point of attention for me. I would prefer more proprietary infrastructure.

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

"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."
"From a use-case scenario, what I like the most is the plug-in. I like the fact that we can do the filtering of these devices offsite independent of the network they are connected to, and we do not have to have traffic coming back inside our network."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"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."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"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."
"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."
"It is easy to use, easy to integrate, and is stable. It's scalable as well."
"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."
"Prisma Access is very stable, and I am very much satisfied with its stability, rating it nine to ten out of ten."
"It supports auto-scaling for mobile users. It auto-scales depending on the mobile user traffic. For example, if 1,000 people are working from home today, and tomorrow, the number increases to 2,000, it is not going to be an issue."
"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."
"Its frontend is user-friendly. It is easy to use for us."
"The most valuable feature of Prisma Access is its ability to provide enterprise-class security for both Internet and internal application access."
"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."
"The most valuable feature of Zscaler Private Access is we do not have to connect to a VPN, it is seamless. It is more convenient for us because we use one agent to cover the internet and VPN access."
"The most valuable features of Zscaler Private Access are its ability to integrate with multiple IDPs and application segmentation."
"The product’s most valuable features are data discovery, activity control, and zero trust exchange."
"This secure connection allows users to connect to the Zscaler VPN and access the resources on the office network, making it a highly valuable component of our system."
"The most valuable features of Zscaler CASB are API integration and DLP."
"You can close your data protection gaps with Zscaler. You can quickly find all the classified, sensitive data across the cloud."
"The most valuable feature is the manageability of the micro tunnels."
"It is easy to use."
 

Cons

"The reporting feature needs improvement."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"Its pricing could be better."
"File integrity monitoring would be very advantageous as an additional feature."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"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."
"The BGP filtering options on Prisma Access should be improved."
"It's not really Prisma's fault, but when you try to create exceptions you don't really have those abilities. You cannot say, on the management platform, "Hey, for these users I want to create these exceptions." That is one thing that I have gotten some complaints about, and we have faced some challenges there."
"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."
"The frequency of updates could be reduced."
"I would like the solution to support a different type of authentication. We can't configure a secondary method for our portal."
"The Prisma Access could improve in terms of adding more machine learning and AI capabilities to automate tasks such as incident response."
"My clients would like to see a more feature-rich product."
"They could add more flexibility and improve product performance."
"Occasionally, there are certain delays in report generation."
"SCMP support would be one of the biggest improvements in my opinion. More speed improvements are also required."
"Sometimes, support takes time since the solution has some bugs that need fixing."
"Setup is a bit complex because there are many steps that need to be taken before onboarding and activating the solution."
"Having a Zscaler-specific device could streamline this process and provide a more consistent user experience across diverse branches."
"More on-prem infrastructure is required when Zscaler Private Access is to be implemented as a single point of entry."
"Zscaler CASB breaks down at times."
"The menu for the ZIA portal could be organized a little bit differently. The most-used modules should be at the top of the menus, not somewhere near the bottom, some of them are not organized well in my opinion."
 

Pricing and Cost Advice

"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."
"It is expensive compared to one of its competitors."
"The overall pricing for iboss is very competitive and transparent."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"It is probably in line with other solutions, but I do not deal with the financial side."
"It's pricey, it's not cheap. But you get what you pay for."
"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."
"Prisma Access is a little bit expensive."
"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."
"I'm still comparing, but the solution is quite expensive."
"Prisma is in the middle of the road. It's not the most expensive, but it's not the cheapest. There aren't any additional costs, to my knowledge. I know they have some extra modules, but we didn't use them."
"There's no reason not to buy the enterprise version that gives you unlimited PoPs, but you must understand the limitations you impose on yourself if you do that. If you go crazy, that allowlist will be too big for Kubernetes clusters."
"Compared to other products, the price is slightly high."
"It is an auto-renewal subscription service."
"The pricing is quite high, especially when it comes to the gateway."
"There is definitely an ROI."
"In the long run, cloud services are not inherently costly."
"The cost is expensive. It depends on the number of users."
"Zscaler Private Access is extremely expensive."
"The product is a little more expensive than other tools."
"The price is competitive."
