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

"As I mentioned, the return on investment is significant, as it saved our office locations' bandwidth because when you are working remotely at home, your internet traffic routes directly to iboss and will not go to your office building, saving bandwidth bottlenecks and ensuring that issues with our building internet circuits will not impact your internet connectivity because you are directly going to the iboss data center."
"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."
"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."
"It was a very easy product to install. It can be deployed very fast."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"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."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"The security and access control features."
"It is user-friendly. It is easy to manage the solution."
"The most valuable features for us include tenant lock, content filtering, and DLP solutions, looking for PII and information being exfiltrated."
"I would describe the experience deploying Cisco Umbrella overall as super easy. It was awesome. It was lovely to deploy it."
"The most valuable features are the dashboard, visibility, and reporting capabilities. Our customers can see how much Umbrella is protecting their organization. If you don't know what you've got, you can't protect it. With Umbrella, you get the visibility and see the protection that it's providing. We can get PDF reports on a weekly basis of any malware activities and any denial of service or command-and-control-type activities."
"Cisco Umbrella is very flexible, and it does not show any kind of delay that someone is responding to their DNS server, outside of their network and outside of their environment."
"The customer experience is very good, and the product improves security posture."
"When we have laptops that leave the building, they could connect to public WiFi before they establish a VPN connection back into the company. For that duration or that period of time when they're not docked in the network or on a VPN, they effectively don't have that full layer of security that I provide inside the building. This tool stands in during that period of time, and we extend the security settings through their basic firewall or their cloud-based firewall at that time. So, we do content filtering and control access, but they also are looking at new domains, IP addresses, and bad requests. They're blocking them on my behalf when a laptop is not sitting behind our security appliances."
"From stability and availability standpoints, it is pretty good."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
"Proofpoint Cloud App Security Broker has positively impacted my organization by resolving all of the security issues related to app security."
"The product is stable."
"The quarantine feature is the solution's most valuable aspect."
 

Cons

"It is stable, but due to growth, it can sometimes be less stable than wanted."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"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, and that is where in 2025 we had to migrate to the Palo Alto-based platform."
"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."
"The endpoint-type solution is an area that needs some improvement."
"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."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"The biggest frustration I have encountered with Cisco Umbrella is that people can exit the Cisco Umbrella roaming client to bypass security, and some technically savvy individuals might know how to bypass it by modifying the hosts file to exclude Cisco Umbrella."
"The detection of wireless attacks or targeted attacks reports many false rates. This is an area that needs some improvement."
"Missing a real data leakage prevention solution."
"From my perspective, I would Cisco Umbrella to give more exposure to my sales engineers. I know I can call them whenever I have an issue, however, more frequent meetings would be awesome."
"If we're trying to deploy it to a Mac through Meraki, it's impossible. The method of deployment for a Mac, and the features available in Meraki, are not compatible at all."
"Something on our end that might make it better is alerting going to our ticketing system. It's not something that we have discussed, but that would be a proactive option for us to provide a learning experience for the staff."
"The pricing changes too fast. We get the license and we need to relicense it because they already made changes to it. We always need to be on top of the licenses because they're always changing."
"The price could be better. The price is definitely a bit high, but we have to pay a premium for Cisco products."
"Proofpoint Cloud App Security Broker should be cheaper."
"They are priced significantly higher and less cost-effective than alternative options."
"The TLS encryption needs to be improved. It's not state of the art."
"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."
"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."
"Pricing depends on the automation requirements of the organization."
"Cisco is expensive. For example, we are looking at Nexus Dashboard, and it's costing about 250,000 euros. I ask, "What do I get from it?" I'm still not convinced that we have to spend on it, so pricing is a problem."
"The price could be lower."
"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."
"Cisco should make the solution cheaper."
"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."
"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."
"Cisco uses subscription models for the pricing and there are three subscription plans."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
"We had an enterprise contract with them for about 32,000 users at that point, which has now grown."
