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

Ensures internet navigation safety and boosts productivity

The features of Cisco Umbrella I prefer most are DNS protection and traffic redirect. With Cisco Talos's threat intelligence, we reduce the impact of malware traffic in our network, and we currently see the behavior of equipment and choose the correct sites. Cisco Talos has helped us reduce the impact of malware traffic. We can see the behavior and choose the correct sites. We're currently testing secure access with Umbrella in order to secure access to core applications. It's a product that the user doesn't even know is there, even though it is protecting them. It's not hard on the equipment. And, for us, it centralizes everything, which improves productivity. With the Experience Insights feature of Cisco Secure Access, we've seen impacts on the management of user connectivity by allowing us to deliver safe connectivity. We are testing the Secure Access product with Cisco Umbrella to improve our connectivity with our users in order to secure access to the corporate applications. Cisco Umbrella is in the cloud, which is nice.

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."

"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."

"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."

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

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

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."

More iboss pros

"The interface is well organized, so you can easily find everything. Even if you don't have much experience with Cisco, you can easily navigate the solution and find your way around. Everything has been done well, from the deployment to monitoring."

"It is user-friendly. It is easy to manage the solution."

"I like the DNS layer security."

"The stability and reliability of the Cisco Umbrella platform are great."

"Cisco Umbrella offers DNS layer security, a secure web gateway, and cloud access security broker functionality."

"With the Experience Insights feature of Cisco Secure Access, we've seen impacts on the management of user connectivity by allowing us to deliver safe connectivity."

"DNS protection, domain blocking, SIP component, and the Cisco Umbrella roaming client are the valuable features of Cisco Umbrella."

"The user interface is great. It's very easy to tailor to our client's environment and needs."

More Cisco Umbrella pros

"The initial setup is easy."

"The most valuable feature of Zscaler Private Access is we do not have to connect to a VPN, it is seamless. It is more convenient for us because we use one agent to cover the internet and VPN access."

"The most valuable aspect of Zscaler Cloud DLP is its automatic DLP feature."

"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."

"The product's most valuable features are cloud-based services and secure internet access. We don't have to set up any physical appliances."

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

"I like its ease of use. It has a single pane of glass for the ZIA and ZPA pieces. It is very manageable. It is also very easy to deploy for secure access, and it gives half-decent coverage for visibility in terms of what the users use and what data is being proxied through the access gateway."

"The best feature is the ability to establish the connection between your public network and automatically connect to the intranet connection."

More Zscaler Zero Trust Exchange Platform pros

Cons

"The dashboards for local use could be better."

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

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

"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."

"The reporting feature needs improvement."

"Sometimes, obviously, there are bugs."

"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."

More iboss cons

"The solution's technical support is not very good."

"Lower costs including licensing, support, and renewals would be beneficial."

"It could be improved by having a local data center and caching, which can provide protection support. I would like to be able to channel my intel and my network traffic to their clouds, and this feature is not available. Advanced protection or any malware file support, which might be required, is not available."

"Cisco Umbrella could be improved by making the policies more granular, as in some cases, it's difficult to find the correct link to open a specific site securely."

"There are a couple of different pieces that have different portals. I know they're working on getting them all into one portal, but that's probably the biggest thing that needs improvement right now. It's not a single pane of glass yet."

"Cisco Umbrella could be improved by making the policies more granular, as in some cases, it's difficult to find the correct link to open a specific site securely."

"The reporting could be improved by way of the information that's displayed. For example, when you pull a report, it shows an internal employee going to many websites, but you can spin that right down by saying a lot of it is being cached."

"It's somewhat pricey for us, however, it's an awesome solution."

More Cisco Umbrella cons

"Another area of improvement is implementation through non-client connectors. The solution can be implemented in two ways. One uses the back file; the other one uses client connectors. So the client connector is pretty fast, but when it comes to non-client connectors and procedures, it's kind of delayed and slow."

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

"Price-wise, it is a costly product and it should be reduced."

"The solution needs to improve a lot of aspects."

"Zscaler CASB should include integrations with other SaaS applications."

"To enhance their offering, it is advisable for them to focus on strengthening the foundation of their architecture. Additionally, they should consider integrating a broader range of services that go beyond what managed service providers typically offer independently."

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

"SCMP support would be one of the biggest improvements in my opinion. More speed improvements are also required."

More Zscaler Zero Trust Exchange Platform cons

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."

"The overall pricing for iboss is very competitive and transparent."

"We have not priced the solution recently, but they were competitive with other vendors in the past."

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

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

"We did a good negotiation, and at the moment, its price is fine."

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

"In terms of licensing, we're not able to be extremely clear with the customer because it's based on their reporting. It's not based on the actual traffic. If they say they have 50 users but they have 80, we'll just buy for 50 users. That's something where we'd like to have more flexibility."

"It needs a better price point."

"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."

"As an educational partner, we get better licensing structures. We are very happy with that. It has been very nice that Cisco has partnered with the educational sector to bring that."

More Cisco Umbrella pricing and cost advice

"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 Private Access is extremely expensive."

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

"Zscaler CASB is an expensive solution."

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

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

"The cost is expensive. It depends on the number of users."

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