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

Protects endpoints wherever they are, always pushing people to the right locations to avoid malicious intent

The most valuable thing is how easy it is to deploy. We did it with 9,000 users at my last job, and it took a week to get to all the endpoints. Doing that without having to physically touch all those endpoints was very simple. The single pane of glass management makes it very easy to manage your rollout. We get a lot of "single panes of glass" and, eventually, you need a pane of panes of glass. But it's always good to have a clear and graphical view, and Umbrella's is nice and easy to read. Definitely, of the panes of glass that we do have, it's one of the easiest to use. The single pane of glass is good to group users together and separate people out. Some people need different types of security. Some people are more vulnerable. Some have more highly valuable assets, like C-suite people. It's really good to be able to have end-users defined inside of that. You don't have to jump around. You don't have to figure out who's who. It's all done through one pane of glass. What most people don't realize is that it's running in the background, which is a really nice aspect when it comes to security. Often, when you deploy a security tool, it takes up CPU performance. Everything slows to a grind. But Umbrella is so simple and easy and it doesn't affect the end-user experience. It's the best of all worlds. It's nice when people realize that they're being protected when they go to the wrong site. I think people are happy that they're protected, but it's nice that they rarely notice it. It's generally easy to maintain network connectivity, but with Umbrella, the nice part is that whichever connectivity you're on, you're always secure. With Umbrella, as long as you're online, you're going to be protected.

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

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

"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 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."

"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 console is cloud-based, which is something I really appreciate."

"Its initial setup was straightforward."

"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."

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

More iboss pros

"Overall, it is a very good solution. It is a simple solution and very easy to set up."

"It makes it really easy to accomplish content filtering. We don't have to do a lot of customization. You just click the box for the content category and it's up to date."

"Cisco Umbrella's integration with other solutions has been a great feature in terms of ease of administration. Administration and troubleshooting are faster. The single pane of glass is great as well. Another great feature of Cisco Umbrella is remote browser isolation. With this feature, you open a virtual browser, and it's seamless to the user. If the user ends up going to a bad website that's passed a policy and something bad tries to download, it will not download into the machine because it is a virtual window somewhere in the cloud. You are protected by this feature."

"The DNS data exfiltration and the blocking of DNS tunneling are the most effective features for threat prevention in our company."

"Provides dependable DNS monitoring of external devices."

"The weekly reportings are great. The investigation is super and the application management is equally great."

"A single pane of glass saves time... This does have a lot of options available for us to see who's doing what, what trends, what errors. We can set up our alerting through it as well. It is definitely a great dashboard."

"Cisco Umbrella is absolutely stable."

More Cisco Umbrella pros

"Has a good zero trust feature."

"The most valuable feature is the manageability of the micro tunnels."

"The most valuable feature is its ability to establish connectivity for remote users and remote endpoints. It offers a high level of granularity compared to typical VPNs, which also encapsulate a lot of I/O."

"The VPN is great for the stability on offer and for the cloud updates and insights you can get."

"The solution offers a simplified network infrastructure and security functions and it enables secure remote access for the users"

"It is easy to use."

"It is straightforward to set up."

"The policies are very easy to implement."

More Zscaler Zero Trust Exchange Platform pros

Cons

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

"To scale up, a new iboss Node Blade Chassis must be purchased."

"File integrity monitoring would be very advantageous as an additional feature."

"Their on-premise hardware's network interface is capped at one gigabit, which is sort of a problem. If you stand a filter up where all traffic flows through that, according to them, in order to go above a gigabit, you have to have multiple devices, which in today's IT seems a little bit silly. They could easily put in an SFP port into their device that could accommodate 10 gigs or at least offer a box."

"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 solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

"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."

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

More iboss cons

"The prices need to go lower. The price of technology is just crazy."

"Cisco Umbrella should add some more documentation on proxies."

"Support for multiple domains is important to us."

"The pricing could be improved."

"I would like to see Cisco enable us to get objects from the internet. I would also like to be able to choose groups."

"The solution is very expensive in Brazil."

"I would like to see more integration between Cisco Umbrella and Cisco DNA Center."

"User interface could be a little smoother and more intuitive."

More Cisco Umbrella cons

"They should work on a replica account. There could be alerts and replica files sent to the DLP team during data collection."

"The DX layer could be better if it had improved visibility."

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

"It has massive room for improvement. The Zscaler product itself is okay, but it doesn't give enough granularity for us as an organization to stipulate rules or processes, especially for data-driven services. For instance, we can stick on SSL inspection, but it's just a click box. It doesn't allow us to go any further into the detail of the SSL inspection. We also can't pull it out without having an additional logging server. It just doesn't give us enough granularity. They should give us more control over the interfaces because it is all backend. They weren't very open to discussing their backend architecture with us in terms of their own data centers. They can maybe a little bit more open about what components are there and how the backend infrastructure works alongside Zscaler. Its licensing can be better. Some of the additional licensing costs are quite high, and they should have certain features ready and available as a baseline rather than having to purchase additional licenses for it. Their support should also be improved. I initially had a consultant from Zscaler for its deployment, but the support that I had throughout the deployment of the project wasn't the best."

"The customers would benefit from more robust documentation and conversations around configurations, as it is slightly complex."

"There aren't really any missing features that I have witnessed."

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

"The menu for the ZIA portal could be organized a little bit differently. The most-used modules should be at the top of the menus, not somewhere near the bottom, some of them are not organized well in my opinion."

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 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 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."

"The licensing part for Umbrella is really flexible."

"Pricing and licensing of Cisco Umbrella is a bit confusing because you have to separate the DNS solution and the full-feature solution. Cisco in Portugal helped us understand which one was the right one for us."

"It was a little bit expensive on a per seat basis, but the company I was running was only a midsize Australian company, and it was a reasonable budget per computer for that system. It started off being a free product, and then Cisco bought it, and it went to a reasonable price. I was using Cisco AMP as well. So, my per computer cost was reasonably high, but for a small company, it was within an acceptable level."

"Our costs were negotiated, and they are okay."

"There are no hidden costs with Umbrella. Everything is included in the package."

"The pricing model is easier compared to some of the other solutions, and it is also competitive."

"The price should be slightly lower than the current price because if you look at the whole solution, it is simply a threat intelligence solution to block blacklisted things. The price should be lower looking at the features provided by the solution. The price isn't too high either, but it could be lower."

"Our licensing fees are on a yearly basis."

More Cisco Umbrella pricing and cost advice

"The price is competitive."

"The product has reasonable pricing."

"The solution has increased prices this year."

"In the long run, cloud services are not inherently costly."

"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."

"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."

"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."

"Zscaler Private Access is extremely expensive."
