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

Blocks threats before they reach the user's device
Cisco Umbrella can be improved in terms of limited coverage and wind vulnerability. The product can only shield a small area, making it less effective for larger spaces or multiple users. Additionally, strong winds can disrupt its functionality, and the opening and closing mechanism can be awkward in tight spaces.
Sumit Bhanwala - PeerSpot reviewer
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 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."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"Technical support is pretty sharp and very responsive."
"The console is cloud-based, which is something I really appreciate."
"The weekly reportings are great. The investigation is super and the application management is equally great."
"It blocks malicious DNS queries daily which is very beneficial."
"Cisco Umbrella is a totally different solution. They are the first to come up with this idea of security. It's a totally new concept of security for everybody, for every time, real time, perfectionism."
"I have found the malware protection feature valuable. It is helpful and deliverable and is able to protect my entire organization from getting compromised. It also prevents us from visiting any malicious sites which are not visible to the users."
"The security and access control features."
"The integration features within, for example, the Cisco VPN product and the Umbrella module are valuable."
"The user interface is great. It's very easy to tailor to our client's environment and needs."
"The most valuable features of this solution are the Web Filtering and the APT."
"The initial setup is easy."
"It has been helpful in maintaining our infrastructure. The granular level control it offers allows us to set application policies per application for each user."
"The most valuable feature is the manageability of the micro tunnels."
"Yes, it is very stable. I have never seen it go down, not once."
"The agent's versatility is notable, used for digital experience monitoring to collect valuable endpoint metrics for troubleshooting."
"The solution is cloud-based with the latest inspection engines, which I find to be amazing."
"The most valuable features of Zscaler CASB are API integration and DLP."
"I find all Zscaler Private Access features valuable because each replaces flawed technologies, such as EPAs being replacements for VPN and PR as a replacement for PAM, so I can't mention only one valuable feature. Overall, Zscaler Private Access is a good solution."
 

Cons

"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."
"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."
"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."
"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."
"The dashboards for local use could be better."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"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."
"Security, overall, can always be improved."
"It's easier for us to have support features with companies who are Cisco representatives, but sometimes, it's hard for us to get the help we need without having to use our contacts within Cisco."
"Network connectivity was a bit of a challenge at the beginning, but we were able to get the right help from Cisco."
"I'd like to see this solution more closely integrate with other products Cisco has in its portfolio."
"They should provide more integrations and bring things together so that there is a more standard feel to their platform. We also use Cisco ISE, and it has a very different feel from Cisco Umbrella."
"The solution could be faster as the process is very slow."
"I would like for them to continue building on IPS and IDS functionalities."
"Actually, we recently switched over to Zscaler because it has more features and it's more scalable than Cisco Umbrella."
"Sometimes applications crash on some machines, and we’d like Zscaler to give us some information as to why that may have happened. We’d like more detailed reports."
"Sometimes, support takes time since the solution has some bugs that need fixing."
"The product must allow users to check logs for an entire year in the local console."
"We would like to extend the SASE applications for Zscaler."
"SCMP support would be one of the biggest improvements in my opinion. More speed improvements are also required."
"Price-wise, it is a costly product and it should be reduced."
"Occasionally, issues arise in the LogStack by a third party, particularly for government websites accessed by numerous users."
"What could be improved in Zscaler Private Access is its notification. For example, if there's a speed issue, there should be a pop-up that alerts the user about it. If there is a network quality issue, for example, it isn't good enough to connect to, or the network quality is bad, there should be a notification from the solution. Zscaler Private Access also needs improvement in terms of its interface and security."
 

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."
"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."
"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 have not priced the solution recently, but they were competitive with other vendors in the past."
"The price of Cisco Umbrella is a little higher than similar solutions, like Gateway."
"Our costs were negotiated, and they are okay."
"The pricing was marvelous."
"We were using the free version, and we implemented the paid version about two months ago. I'm paying a fair price, but everything is negotiable with Cisco. One of the benefits that I got by having Cisco Umbrella is the licensing of the Cisco AnyConnect VPN client."
"Cisco Umbrella is not a cheap product. However, it's not a matter of the cost; it's more a matter of the value of security. It is easy to measure this value when you have a security incident. I think the price is a good trade-off for a product that can help you avoid security threats."
"We have a security Enterprise Agreement with Cisco, so the pricing is good."
"It has a reasonable price. It is certainly not as expensive as it used to be. It is in line with other offerings on the market. There are a number of different flavors of Umbrella. They could bring Umbrella SIG down a bit because its price is a little bit high for what it does, but I also understand why its price is high."
"I rate the tool's pricing a five out of ten."
"The product is a bit expensive."
"The price is competitive."
"Zscaler CASB is an expensive solution."
"In terms of market positioning, I would describe Zscaler Private Access as offering optimal pricing. Based on our experience, Cato Networks tends to be slightly more expensive."
"The solution is expensive."
"The cost is expensive. It depends on the number of users."
"Pricing for Zscaler Private Access is moderate. It's acceptable, though I can't give you the exact price currently. It's not too expensive, and on a scale of one to five, I would rate it a four out of five in terms of pricing."
"The product has reasonable pricing."
