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

Stable product with essential document tracking features
In my organization, we worked with around ten to fifteen different technologies, including Bitglass, and CASB was not among our top priorities. While CASB might benefit some organizations, it was optional for our specific setup, considering the other security measures and technologies we had in place. I found no particularly valuable features regarding CASB resolutions. There are other tools available that can achieve the same functionalities and perform similar tasks. For example, I can accomplish tasks like encryption or secure data movement from our office to the internet using alternative services like Zero Trust solutions. Because of this, our organization considered removing it from our system due to its limited benefits compared to other products.

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

"iboss is among the few products providing inline filtering where no application is needed on the device."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."
"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."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"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."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
"The product is stable."
"The quarantine feature is the solution's most valuable aspect."
"From stability and availability standpoints, it is pretty good."
"The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users."
"One on the main benefits is protection all time from anywhere."
"It is easy to set up the solution."
"Zscaler Internet Access protects using data loss prevention. If you have a CASB exposing your cloud out into the network, then Zscaler Internet Access will go ahead and control that unknown cloud application in the CASB, protecting it. There is also data detection with exact data match. This improves the data coming into your cloud so you are protecting it."
"Zscaler Internet Access's best feature is the granular policy controls."
"​After a proper implementation, the maintenance is very low.​"
"The most valuable features of Zscaler Internet Access are it's on the cloud, high network performance, and the interception of users is very easy."
"The VPN is valuable, as the whole technology is very different from a traditional VPN."
 

Cons

"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."
"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."
"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."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"The dashboards for local use could be better."
"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."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"They are priced significantly higher and less cost-effective than alternative options."
"Proofpoint Cloud App Security Broker should be cheaper."
"I think some of the hiccups that we had were with the number of domains that we had and how that had to be implemented in Proofpoint."
"The TLS encryption needs to be improved. It's not state of the art."
"What could be improved in Zscaler Internet Access is its price. It could be cheaper."
"It also needs better integration with other applications as well. There are some restrictions."
"The deployment process of Zscaler Cloud Connector needs to be more user-friendly."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"The tool should improve the predefined dictionaries."
"The OS capabilities and WSL support could be improved."
"Technical support could be better."
 

Pricing and Cost Advice

"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."
"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."
"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."
"We had an enterprise contract with them for about 32,000 users at that point, which has now grown."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
"The pricing for Zscaler Internet Access could be made cheaper."
"The pricing is fair based on its competitive market."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"Our monthly fee is around R3000."
"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."
"​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 price is competitive. It's not cheap and it's not expensive."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
