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

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"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."
"Our primary use case for this product is DLP,"
"This product is solid, fairly easy to use, and reliable."
"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."
"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."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"I would say iboss is a very good product; its scalability is very good, and it's seamless for the user."
"Umbrella is probably one of the best tools out there in all the security landscape."
"Using this solution has meant that we've needed to make fewer firewall changes."
"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."
"By delivering security from the cloud, it will save money and provide more effective security."
"Cisco Umbrella is a very good product as of now as there is no competition."
"One of the great advantages of Umbrella DNS is that it's really simple to deploy. It's easy to install, the users do not notice that it's there, and it doesn't interfere with your work. The simplicity and transparency are great advantages of Cisco Umbrella."
"By using Cisco Umbrella, you are sure of inspecting all the traffic. Whenever the user machine is connected to your network, it is inspected. That's the best thing. It means you are sure that nothing is being exported or imported without your choice. That is the best feature."
"DNS protection, domain blocking, SIP component, and the Cisco Umbrella roaming client are the valuable features of Cisco Umbrella."
"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 product is stable."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
 

Cons

"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."
"The reporting feature needs improvement."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"I appreciate that iboss's single pane of glass console gives centralized visibility into web traffic, user activity, security policies, and alerts from one dashboard, allowing us to quickly investigate incidents and monitor policy violations without switching between multiple tools, improving operational efficiency; however, the dashboard customization and reporting could be more flexible."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"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."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"Cisco Umbrella is difficult to manage and needs to include a dashboard. It needs to improve pricing as well."
"Security, overall, can always be improved."
"The different levels of security, such as backend security and internet security, need improvement."
"Looking at the full umbrella suite in the light of SASE, Secure Access Service Edge, they are clearly lacking in the inline CASB."
"Client delivery and client updates should be improved. Client delivery was not as easy as expected. Another area for improvement is the integration of escalation procedures for security issues."
"All in all, I can not recommend OpenDNS as a one-size-fits-all solution for security and compliance, especially for larger organisations."
"If the virtual appliances could also gather traffic bandwidth reports, that would be great."
"A feature I would appreciate seeing enhanced in Cisco Umbrella would be the ability to add or remove agents that we have, instead of just relying on how long the devices have been connected to the platform."
"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

"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."
"The overall pricing for iboss is very competitive and transparent."
"It is probably in line with other solutions, but I do not deal with the financial side."
"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 not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."
"The licensing part for Umbrella is really flexible."
"You get what you pay for if you break the solution up into tiers."
"You can request an evaluation license​."
"There is a subscription cost."
"Cisco uses subscription models for the pricing and there are three subscription plans."
"The pricing is great and very competitive with the rest of the market."
"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."
"The price could be lower."
"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."
