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

"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."

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."

"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."

"Our primary use case for this product is DLP,"

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

"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."

More iboss pros

"I find Fortinet FortiCASB easily customizable."

"The product’s most valuable features are data discovery, activity control, and zero trust exchange."

"The most valuable features of this solution are the CASB solutions, which is protecting their Office 365."

"The in-line DLP feature is one of the most vital features"

"The most valuable feature is its seamless integration capabilities, streamlining the process by eliminating the need for extensive installations."

"The scalability is pretty good."

"The policies are very easy to implement."

"The customer service and support are very good."

"Zscaler Cloud DLP provides you with basic DLP features that you get out of the box such as keywords, regular expressions, and data identifiers, for example, your social security numbers, and credit card numbers, with everything built into the product, so you can directly use those features within the policies. You don't need to create it from scratch, and to me, this is the biggest benefit of Zscaler Cloud DLP. You have a lot of templates to choose from in the solution, rather than having to create templates from scratch or reinvent templates."

Cons

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."

"The dashboards for local use could be better."

"Sometimes, obviously, there are bugs."

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."

"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."

"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 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."

"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."

More iboss cons

"The turnaround time to deploy Fortinet FortiCASB could be improved. The learning curve for deploying, configuring use cases, and rules can be better."

"The turnaround time to deploy Fortinet FortiCASB could be improved."

"Sometimes, support takes time since the solution has some bugs that need fixing."

"The solution's granularity should be improved because it has limited granular options to control, visible, allow, block, delay, and receive."

"The area that requires improvement is their support. The current support is lacking."

"We'd like to have two-factor authentication that is quite simple."

"Having a Zscaler-specific device could streamline this process and provide a more consistent user experience across diverse branches."

"Zscaler CASB breaks down at times."

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

"User management can be improved."

More Zscaler Zero Trust Exchange Platform cons

Pricing and Cost Advice

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

"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."

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

"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."

Information not available

"My company is a Zscaler Private Access partner, so the customers pay for the license fees."

"Zscaler Private Access is extremely expensive."

"Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."

"It's expensive currently. But when purchasing for a large number of users, there's room to negotiate. It's really up to the procurement team."

"Zscaler CASB is an expensive solution."

"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."

"Zscaler Cloud DLP is moderately priced. We pay around 2 million rupees per year."

"The product is a little more expensive than other tools."
