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

Has provided advanced features and reliable support with a learning curve in the beginning
I work with Palo Alto Firewall, and I am also interested in Prisma Access Browser and DLP. I remember that I worked with Palo Alto as a user and a customer. Palo Alto has extremely advanced technology. Prisma Access Browser is the most capable, advanced, and flexible product. For Prisma Access Browser overall as a product, I would give it a 10 out of 10. It depends on the infrastructure of my company, but it's not in daily usage, and we can work without it, yet for qualities and functionalities, I find it to be excellent. I basically work with SD-WAN, with firewalls; this is my current field. My overall rating for Prisma Access Browser is 10 out of 10.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.

Quotes from Members

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

Pros

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"Our primary use case for this product is DLP,"
"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."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Technical support is pretty sharp and very responsive."
"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 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 has significantly lowered the number of security incidents. It is crazy how much it blocks and how much it is aware of the outside danger."
"Prisma Access Browser is the most capable, advanced, and flexible product."
"The policies are very intuitive and easy to configure, with very little possibility of messing things up."
"Zscaler Web Security protects our users in remote locations from internet threats - even if they are not connected to our network."
"The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that."
"The most valuable feature is bandwidth control."
"For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
"Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."
"We like Zscaler's traffic filtering, web security, DLP, and IPS features. The real-time threat protection is excellent."
"We use ZIA for outbound internet connectivity. The internet traffic of on-prem users will be directed to the ZIA cloud for security checks and web filtering."
 

Cons

"I am currently doing a PoC of the zero trust aspect of it. Compared to other similar solutions, it is hard to get around each feature. It takes a while to get used to it."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"File integrity monitoring would be very advantageous as an additional feature."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."
"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."
"The maturity of the product needs improvement as the implementation is very complex."
"In the beginning, the solution may not be very user-friendly and could be complex."
"It also needs better integration with other applications as well. There are some restrictions."
"Sometimes it's not easy to use during large deployments of workstations."
"An improvement would be if they could provide an out-of-the-box experience, like 20 to 30 features all ready to go. In comparison, LogRhythm offers out-of-the-box features. With Zscaler Internet Access, there is firewall IPS, multiple security services, filtering, DLP, and CASB browser isolation. These are things that all users are going to be using. However, when an administrator or architect would start building this, I would definitely need to engage professional services to help clients do it."
"We'd like to have more plugins and integration."
"The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."
"They block Zscaler IPs when the traffic origin is from Zscaler IPs. They've been blocked by certain government organizations so the end users are not able to visit those websites unless we ask them to unblock those IP. This is a bit problematic."
"They could provide more time for the onboarding the training of an IT person."
"Sometimes, support isn't available."
 

Pricing and Cost Advice

"We have not priced the solution recently, but they were competitive with other vendors in the past."
"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 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 probably in line with other solutions, but I do not deal with the financial side."
"The overall pricing for iboss is very competitive and transparent."
"It is expensive compared to one of its competitors."
Information not available
"It is costlier than other solutions."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"If we need any extra features, the price will increase."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"The tool is moderately priced."
