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.

Secure browsing has protected users from DNS threats and improves malware defense
The major issue is that sometimes when you install the client, it shows you protected and displays that it is live with the backend servers and everything. However, in reality, it was not getting any feed from the main client and is just sending your traffic to open DNS, which sometimes causes an issue because the protection you have implemented can be breached by users. The primary thing that Cisco Umbrella lacked most of the time is their client. Previously, they had a separate Cisco client. Now they have merged everything into the Cisco Secure Endpoint client—one client for everything, for Cisco Endpoint, for Cisco AnyConnect, and for Cisco Umbrella, which they did probably in 2025.

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

"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."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"Our primary use case for this product is DLP,"
"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."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"The console is cloud-based, which is something I really appreciate."
"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."
"I would say iboss is a very good product; its scalability is very good, and it's seamless for the user."
"I haven't found any issues related to latency or any other issue."
"Cisco Umbrella is easy to monitor, manage, and deploy."
"Cisco's support is fantastic, providing assistance when needed, especially during the initial installation process."
"I was pretty amazed by the wide variety of security features and reports on a single dashboard."
"Application performance has greatly improved and there are less operational issues. Productivity has been going up because we have less operational issues. Also, we have happy customers."
"This is a very good solution and my clients are impressed with it."
"The DNS data exfiltration and the blocking of DNS tunneling are the most effective features for threat prevention in our company."
"DNS protection, domain blocking, SIP component, and the Cisco Umbrella roaming client are the valuable features of Cisco Umbrella."
"The product is stable."
"From stability and availability standpoints, it is pretty good."
"The quarantine feature is the solution's most valuable aspect."
"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

"The reporting feature needs improvement."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"File integrity monitoring would be very advantageous as an additional feature."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"Sometimes, obviously, there are bugs."
"The easiest device I have set up was the Barracuda line of products."
"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."
"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."
"I am unsure if Cisco Umbrella offers a Windows option for running the server."
"The major issue is that sometimes when you install the client, it shows you protected and displays that it is live with the backend servers and everything; however, in reality, it was not getting any feed from the main client and is just sending your traffic to open DNS, which sometimes causes an issue because the protection you have implemented can be breached by users."
"In my experience with Umbrella support, sometimes the response times take a bit more time than we would like... sometimes, if you go through email, it can take quite a while to get a response."
"With any Cisco product, it's the licensing side of things that needs improvement."
"Cisco Umbrella does not have a Malware Protection engine itself."
"It has happened in the past that Cisco Umbrella has denied us access to secure websites."
"Network connectivity was a bit of a challenge at the beginning, but we were able to get the right help from Cisco."
"It would be good to have more extensions to third-party products and a client for other device types."
"They are priced significantly higher and less cost-effective than alternative options."
"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."
"Proofpoint Cloud App Security Broker should be cheaper."
"The TLS encryption needs to be improved. It's not state of the art."
 

Pricing and Cost Advice

"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."
"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 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."
"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."
"There are three models for licensing with different feature sets."
"The pricing was marvelous."
"Its value exceeds its pricing."
"The price depends on the use case, and it's a bit linear. But it depends on the customer's strategy and how Cisco plans to optimize the costs."
"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."
"We were using the free version, and we implemented the paid version about two months ago. I'm paying a fair price, but everything is negotiable with Cisco. One of the benefits that I got by having Cisco Umbrella is the licensing of the Cisco AnyConnect VPN client."
"I think it's worth the money."
"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."
