Enhances web security with a single pane of glass and flexible deployment

I don't see any need for improvement; one of the really good things about iboss as a company is that they listen to customer feedback. I have suggested enhancements, and they are responsive, making changes for the better, and they do a lot of testing. To improve iboss, although we haven't used it, we considered the VPN solution that comes with the highest tier licensing, which includes DLP and various other add-ons. We prefer using another product which automatically logs you back onto your network when turning on your PC. With iboss, the connection is manual, which doesn't meet our needs. Additionally, sizing can be tricky because, although the initial recommendations may seem adequate, actual usage may require more gateways than anticipated.

Ensures internet navigation safety and boosts productivity

The features of Cisco Umbrella I prefer most are DNS protection and traffic redirect. With Cisco Talos's threat intelligence, we reduce the impact of malware traffic in our network, and we currently see the behavior of equipment and choose the correct sites. Cisco Talos has helped us reduce the impact of malware traffic. We can see the behavior and choose the correct sites. We're currently testing secure access with Umbrella in order to secure access to core applications. It's a product that the user doesn't even know is there, even though it is protecting them. It's not hard on the equipment. And, for us, it centralizes everything, which improves productivity. With the Experience Insights feature of Cisco Secure Access, we've seen impacts on the management of user connectivity by allowing us to deliver safe connectivity. We are testing the Secure Access product with Cisco Umbrella to improve our connectivity with our users in order to secure access to the corporate applications. Cisco Umbrella is in the cloud, which is nice.

Security and Continuity Manager at Rolinco NV

Deployment has been seamless with insightful data categorization and enhanced control

The features of Microsoft Defender for Cloud Apps that I have found most valuable include the overall portal view, with bubble graphs which give us insight into what goes where in the categorization, nowadays with Generative AI but all kinds of categorization, collaboration, etc. That central view of the portal is very useful for us. The impact of Microsoft Defender for Cloud Apps on our organization's ability to assess and manage app related risks has been significant because we have more visibility. Therefore, we can add more control, and we have already done so. This was not possible in the old solution, in the old CASB solution with Netskope. We now can see on the spot, and we do that almost weekly, what the end users are utilizing, which cloud providers or cloud apps they're using. The visibility into OAuth apps provided by Microsoft Defender for Cloud Apps is very good. The visibility into risk and risk management of our organization's Generative AI apps is very nice, as you can choose the category Generative AI and then see exactly what traffic has been going to and from Generative AI in the cloud. This makes us very insightful on what is used within the company. We have some policies on blocking specific Generative AI, and we use within our company one particular AI part, which is CoPilot of Microsoft. In this way, we can see what the end users are using other than CoPilot, and that makes us more in control. The effectiveness of the integration of Microsoft Defender for Cloud Apps with Defender XDR and defending against SaaS attacks is very intuitive. It works immediately if we create a new policy or in Purview or in Microsoft Defender for Cloud Apps, or when we make an app unsanctioned by blocking it, then it is almost immediately, or at least within a couple of hours, effective on all the endpoints where the EDR is running. This gives us much better control over things than before.

Quotes from Members

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

Pros

"iboss is among the few products providing inline filtering where no application is needed on the device."

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

"Our primary use case for this product is DLP,"

"Technical support is pretty sharp and very responsive."

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."

"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."

"The console is cloud-based, which is something I really appreciate."

More iboss pros

"Reports provide insight into internet usage and information helpful in creating QoS rules."

"My overall rating for Cisco Umbrella is ten out of ten."

"We are very new users of the solution and are still in the exploration stages, but we are happy with the product thus far."

"The security and access control features."

"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."

"DNS protection, domain blocking, SIP component, and the Cisco Umbrella roaming client are the valuable features of Cisco Umbrella."

"Using this solution has meant that we've needed to make fewer firewall changes."

"There is much differentiation within the licensing so if anyone wants DNS security from the DNS security log, we are there already, and if anyone wants to go to a secure internet gateway, that is also available. We can get the integrated cloud DLP license keys. That is a good benefit with Cisco Umbrella. You can get a complete solution in a single licensing."

More Cisco Umbrella pros

"The most valuable feature is its policy implementation."

"We have become more aware of what services our users are using, how often they are using them, and what data is being sent out of the organization and to which services. So, it is really a lot about visibility and helping us make decisions based on that. It drives some of our policy decisions for adding extra security controls."

"The general usability of the solution is very straightforward."

"The product helps us with privileged identity management to control who has access to what and for how long."

"Threat detection is its key feature, and that's why we use this tool. It gives an alert if a PC is attacked or there is any kind of anomaly, such as there is a spike in sending emails or we see an unauthorized website being accessed. So, it keeps us on our toes. We get to know that there is something wrong, and we can isolate the user and find any issues with it. So, threat detection is very robust in this tool."

"Defender for Cloud Apps has given us good visibility regarding what we've allowed into our environment until now."

"The most valuable feature of Microsoft Defender for Cloud Apps is to stop shadow IT."

"In Microsoft Defender for Cloud Apps, there is an option to enable files. Once you enable that, it will give you all the files in your organization and where they are located in the cloud... That feature is very useful for investigation purposes."

More Microsoft Defender for Cloud Apps pros

Cons

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

"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."

"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."

"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."

"The dashboards for local use could be better."

"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."

More iboss cons

"Data reporting could be improved."

"Customization for basic users can be complex, as it is targeted toward only technical users."

"I'm hoping for the conversion of Cisco ZTNA's features from Duo to Umbrella."

"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."

"It would be good to have more extensions to third-party products and a client for other device types."

"It should have a real-time malware classification engine. It should check the malware on the website. It would be good if it had a real-time malware check for the websites because currently, it just compares the DNS queries of the blacklist. It should also have malware control over file execution and the types of files that the users are allowed to download."

"The integration with Cisco could be better."

"I would like to see more integration between Cisco Umbrella and Cisco DNA Center."

More Cisco Umbrella cons

"Defender for Cloud apps is primarily useful for Azure apps. It has limited capabilities for applications based on other cloud platforms."

"There are some features, such as user navigation content filtering, that are disabled by default, and it probably makes sense to enable them by default."

"A significant improvement I would like to see is the integration into a single pane of glass, which would allow me to view everything in one place rather than having to switch between different areas."

"I believe it's only set to be integrated with Microsoft Defender for identity and identity protection. I would like to see it available for use with something like Office 365 Defender. I don't think it's integrated with that yet."

"The integration with macOS operating systems needs to be better."

"The product is very good so far, however, it would be better if it could include more up-to-date threat protection."

"There are certain areas where the product could improve, such as some functionalities that did not work as expected."

"The insights could be improved, especially in reporting."

Pricing and Cost Advice

"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 overall pricing for iboss is very competitive and transparent."

"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 probably in line with other solutions, but I do not deal with the financial side."

"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 pricing is pretty fair. It's good."

"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 uses subscription models for the pricing and there are three subscription plans."

"I am not sure, I don't have the numbers in front of me, but I think it's $1.00 or so per device/month."

"Our costs were negotiated, and they are okay."

"I rate the tool's pricing a five out of ten."

"Cisco has a set price for a single license up to 100, but whenever we get over 100, we have to ask for a quote."

More Cisco Umbrella pricing and cost advice

"It is a little bit expensive. When you want to have the complete package with Office 365, Defender, and everything else, it is expensive."

"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."

"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."

"It has pretty good pricing."

"I'm not totally involved in the pricing part, but I think its pricing is quite aggressive, and its price is quite similar to Netskope. Netskope has separate licensing fees or additional charges if you want to monitor certain SaaS services, whereas, with MCAS, you get 5,000 applications with their Office 365. It is all bundled, and there's no cost for using that. You only have the operational costs. In the country I am in, it is a bit difficult to get people with the required skill sets."

"We are an MST and we do not pay for the solution. However, the price of the solution could be better."

"We have an educational licensing agreement. It's a customer agreement for multiple years."

"The pricing is fair."
