Cloud gateway has strengthened remote web security and now needs better Mac and ISP support
The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

Has required extensive customization for non-technical users and still needs better simplification
Customization for basic users can be complex, as it is targeted toward only technical users. It would be beneficial if Cisco simplifies the customization process while still ensuring strong security to prevent unauthorized access. Simplifying the customization part could enhance Cisco Umbrella, but overall, it is a good solution for me.

Layered security has protected our cloud AI apps and significantly reduced attack incidents
The best features Proofpoint Cloud App Security Broker offers are multilayer protection against security attacks and escalation. The escalation feature in Proofpoint Cloud App Security Broker is valuable because we are using more and more users, and it is very scalable in relation to the number of users using the same app on the cloud. The performance of Proofpoint Cloud App Security Broker stands out as the number of attacks blocked is more than 90%. Proofpoint Cloud App Security Broker has positively impacted my organization by resolving all of the security issues related to app security. I can share specific outcomes, such as a reduction in the number of incidents, which is more than 90% related to the past.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The iboss solution gives me the ability to scan the traffic through all the ports, through all the 131,000 PCP and UDP ports, and with this ability, we have the granularity also for consults over social media and applications on mobile, and this is an advantage that the customers are looking for right now."
"It was a very easy product to install. It can be deployed very fast."
"Its initial setup was straightforward."
"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."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"From a corporate perspective, I understand that it's important to keep the company data safe."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"The documentation is good, and we have been able to resolve any issues ourselves."
"DNS protection, domain blocking, SIP component, and the Cisco Umbrella roaming client are the valuable features of Cisco Umbrella."
"The customer experience is very good, and the product improves security posture."
"As far as the IT infrastructure team goes, we're all happy with the product; it definitely takes a lot of load off of our plate and it's been functioning very efficiently and effectively, doing everything we need it to do."
"Cisco's Umbrella client product is superb, it worked so well for us and was easy to deploy."
"The most valuable feature is the ability to block users from reaching places that they should not even try to reach has been a boon."
"The most valuable feature is the ease of use."
"Cisco Umbrella is specifically designed for DNS protection, with features including a user-friendly console and the easiest installation, and it offers very prominent threat feeding from different Talos sources, securing multiple platforms while helping protect from malware and unsafe sites and mitigating DNS attacks to ensure secure browsing for end users."
"The product is stable."
"The quarantine feature is the solution's most valuable aspect."
"From stability and availability standpoints, it is pretty good."
"Proofpoint Cloud App Security Broker has positively impacted my organization by resolving all of the security issues related to app security."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
 

Cons

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"Sometimes, obviously, there are bugs."
"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."
"iboss can be improved because the integration could be better; you need to import all the sites that you access today, and there are a few problems whenever you import thousands of websites, making the integration process messy for the users."
"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."
"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."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"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."
"It's somewhat pricey for us, however, it's an awesome solution."
"I'm hoping for the conversion of Cisco ZTNA's features from Duo to Umbrella."
"We have had issues because of functionality that it didn't support at the time, which is why it has not been fully deployed yet."
"This solution does not give us full, 360-degree protection."
"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."
"When I looked at it, it was impossible to manage app control."
"There are a couple of interface issues."
"Lower costs including licensing, support, and renewals would be beneficial."
"The TLS encryption needs to be improved. It's not state of the art."
"They are priced significantly higher and less cost-effective than alternative options."
"Proofpoint Cloud App Security Broker should be cheaper."
"I think some of the hiccups that we had were with the number of domains that we had and how that had to be implemented in Proofpoint."
 

Pricing and Cost Advice

"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."
"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."
"In the region I'm from, that of EMAR, Europe, the Middle East, Eastern Asia and Africa, our organizations do not have many liquid cash assets, so the price could be better."
"You get what you pay for."
"The pricing is great and very competitive with the rest of the market."
"In my opinion, Cisco Umbrella now has a good price in the basic packages. When it comes to Cisco Umbrella SIG Essentials package and Cisco Umbrella Secure Internet Gateway (SIG) Advantage package, it depends on whether the project has a good price or not"
"The pricing model is easier compared to some of the other solutions, and it is also competitive."
"The licensing part for Umbrella is really flexible."
"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."
"You get what you pay for if you break the solution up into tiers."
"We had an enterprise contract with them for about 32,000 users at that point, which has now grown."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
