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.

Offers good reliability and availability to users
Sometimes, cost is one component that customers complain about, especially if they compare it with some of its competitors. Zscaler's pricing seems to be a bit on the higher side. I think the pricing model is also something that the tool can probably look into to optimize or improve for the customer so that it can be a competitive tool commercially. The solution's technical support needs to be improved, especially by offering a better support structure for different geographical areas.

Quotes from Members

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

Pros

"Technical support is pretty sharp and very responsive."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Content filtering is the most useful feature of iboss."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"It was a very easy product to install. It can be deployed very fast."
"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."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"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 tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
"From stability and availability standpoints, it is pretty good."
"The quarantine feature is the solution's most valuable aspect."
"The product is stable."
"We like Zscaler's traffic filtering, web security, DLP, and IPS features. The real-time threat protection is excellent."
"The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users."
"The most valuable feature is bandwidth control."
"The protection is most valuable."
"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."
"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 has helped us reduce the time that we spend managing security policies by about four hours a week. We can use this time to focus on other things, especially the IT team."
"Overall, we're very happy with our product."
 

Cons

"The reporting feature needs improvement."
"Sometimes, obviously, there are bugs."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"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."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"Its pricing could be better."
"File integrity monitoring would be very advantageous as an additional feature."
"The dashboards for local use could be better."
"Proofpoint Cloud App Security Broker should be cheaper."
"They are priced significantly higher and less cost-effective than alternative options."
"The TLS encryption needs to be improved. It's not state of the art."
"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."
"One feature I am missing is the ability to connect automatically to internal monitoring systems."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
"The interface for administration could be better. They should upgrade the management portal."
"Sometimes it's not easy to use during large deployments of workstations."
"Cloud App’s database should be improved."
"Sometimes, support isn't available."
"I don't know whether it's Zscaler or not, however, sometimes I can't access my time management. I need to wait and try again a few hours later. Typically, if I let some time pass, I can access it again."
"Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."
 

Pricing and Cost Advice

"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."
"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."
"It is probably in line with other solutions, but I do not deal with the financial side."
"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."
"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."
"We have found the solution to be expensive."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The price is competitive. It's not cheap and it's not expensive."
"Zscaler is transparent about its pricing model."
"Licenses are available on a per-host basis. Some features like sandboxing require an additional fee, but most standard features are included in the license."
