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

"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."

"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."

"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."

"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 a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

"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."

"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."

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."

More iboss pros

"Cisco is a very efficient and on-point solution that controls the whole network and settings on one page. We can monitor the entire network."

"Improves security through DNS visibility, which can block malware, phishing, C&C, etc."

"We immediately block impersonating users from accessing services over Cisco Umbrella-controlled devices."

"The implementation is pretty easy."

"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 Umbrella is absolutely stable."

"Cisco's support is fantastic, providing assistance when needed, especially during the initial installation process."

"The primary advantage of Cisco Umbrella is its ability to safeguard our users no matter where they are working from - whether it's in the office or remotely, as per the new work model that has emerged globally. This integrated security solution has simplified our lives by combining all the necessary security measures in one product. Additionally, deploying the product is all it takes to protect all our users."

More Cisco Umbrella pros

"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."

"It has some good data security and WIP features, providing secure Internet access."

"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."

"You can close your data protection gaps with Zscaler. You can quickly find all the classified, sensitive data across the cloud."

"Overall, the solution does a pretty good job at web filtering."

"The solution is the best for storage."

"It is a stable solution."

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

More Zscaler Zero Trust Exchange Platform pros

Cons

"The reporting feature needs improvement."

"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."

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

"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."

"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."

"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."

"Its pricing could be better."

"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."

More iboss cons

"The pricing could always be a little bit better."

"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."

"It would be good to have more extensions to third-party products and a client for other device types."

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

"They need to improve analytics so they report on more of the specifics of user activity."

"I would like to see a graphical representation of the entire network."

"The integration with other solutions is a little complex. If you want to integrate with something like ArcSight or LogRhythm or Splunk, you need to do a lot of configuration. There are no easy ways to implement it."

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

More Cisco Umbrella cons

"In the next release, I would like to see RE2 Regex supported."

"There could be a feature to view the VPN tunnel activities in terms of configuration."

"There are latency issues with the solution. They are small, however, they are there when you compare it to other vendors."

"While Zscaler supports client-initiated connections, it does not support server-initiated connections. This is a feature that Zscaler may consider adding in the future."

"There could be additional ways to define proximity. Additionally, they should provide some exclusion options for specific policies and an ability to control the DLP engine."

"It has a limitation, if you are creating a rule or something for a web application or something, you could only add five users, not more than that. Five or four users are only included in a rule. If you want to create a rule for more than five or four users, you have to go through other methods, not particularly with the application. Working within the application with this method would be quite easy as compared to listing a URL or a normal IP address."

"Zscaler Cloud DLP needs to improve its compatibility with other security tools."

"Zscaler Private Access's reporting is poor. We should have more insight into the reports regarding what is blocked and allowed."

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."

"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 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 expensive compared to one of its competitors."

"Cisco has a model called ELA. With ELA, if you buy the solution you will have the complete security portfolio and you can pay it yearly or after three years, it depends on the contract."

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

"The solution’s pricing is reasonable."

"I think it's worth the money."

"I am not sure, I don't have the numbers in front of me, but I think it's $1.00 or so per device/month."

"The pricing is pretty fair. It's good."

"You get what you pay for if you break the solution up into tiers."

"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."

More Cisco Umbrella pricing and cost advice

"The product is a bit expensive."

"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."

"The pricing is expensive and on the higher end. Honestly, in my opinion, it is not worth the price."

"Zscaler SASE software is quite expensive compared to other solutions"

"There is definitely an ROI."

"Zscaler Private Access is extremely expensive."

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

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