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 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."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"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."
"This product is solid, fairly easy to use, and reliable."
"Its initial setup was straightforward."
"iboss is definitely very good in terms of service."
"The students were always protected, and the content filtering worked very well, seeming to work better than other products we had tried previously."
"Umbrella is probably one of the best tools out there in all the security landscape."
"I have found the malware protection feature valuable; it is helpful and deliverable and is able to protect my entire organization from getting compromised, and it also prevents us from visiting any malicious sites which are not visible to the users."
"The most valuable feature is its ability to detect if a URL has malware or is vulnerable."
"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."
"The most valuable features for us include tenant lock, content filtering, and DLP solutions, looking for PII and information being exfiltrated."
"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."
"Overall, as a program, it has saved us a ton of time and stress by not having to worry about malware or viruses or anything malicious."
"When it comes to hybrid work it's pretty effective. We've got the agents. We can protect people inside our building and, when they're using their laptops out in the field, they're still protected. It's working well."
"The quarantine feature is the solution's most valuable aspect."
"The product is stable."
"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."
 

Cons

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"File integrity monitoring would be very advantageous as an additional feature."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"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."
"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."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"There is room for improvement in the dashboard. It could stand to be a bit more detailed. I would also like to be able to customize the dashboard to focus more on what is important for my company."
"Pricing needs to be reduced for SMB based on the blocking capabilities and the lack of other features that you just cannot do in DNS, such as authentication-based filtering."
"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."
"If I want to see which users access a website, I need an Active Directory registered on Umbrella's cloud."
"It would be better if there was a little bit of flexibility for organizations that don't have SD One in their environment. Because of the complexity of the environment, it's not easy to actually turn on the feature of the secure internet gateway for our users. We have not been able to explore that option yet."
"This solution is difficult to configure."
"When I looked at it, it was impossible to manage app control."
"Customization for basic users can be complex, as it is targeted toward only technical users."
"They are priced significantly higher and less cost-effective than alternative options."
"Proofpoint Cloud App Security Broker should be cheaper."
"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

"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."
"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."
"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."
"It is expensive compared to one of its competitors."
"It is probably in line with other solutions, but I do not deal with the financial side."
"We did a good negotiation, and at the moment, its price is fine."
"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."
"Cisco should make the solution cheaper."
"I rate the tool's pricing a five out of ten."
"There are three models for licensing with different feature sets."
"The product is pricey compared to Cisco Firepower."
"The licensing fee is paid on a yearly basis."
"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."
