It's easy to roll out, and their understanding of our business made it seamless

One aspect we value about iboss is its simplicity. Their customer service is brilliant, and they are super responsive and knowledgeable. It's easy to roll out, and their understanding of our business made it seamless. We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times. The user interface is highly intuitive. Our IT team picked it up with minimal training. It's arranged so that it's easy to find where things are. Another advantage is the single pane of glass console, which gives you visibility into what's happening. We're not fully there yet because we haven't implemented zero trust, but we're excited about the possibilities from the demos we've seen. We launched a POC of iboss' ChatGPT Risk Protection feature two weeks ago. AI is a great tool, but you need to be careful what you put into it. My biggest fear is employees inputting sensitive corporate information or customer PII data into one of these chatbots. I was impressed by our trial of the feature. It's exactly what we wanted. Now, when a user goes to ChatGPT, there's a banner warning them not to share information, and we can block conversations containing customer data like bank details and email addresses. I don't want to stop people from using it, but we need visibility. We've only tried it on a test group of 15 people. You can configure it to look for specific keywords or integrate it with your DLP policy if you have that configured

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.

Cloud-based platform simplifies device and data center management

I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.

Quotes from Members

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

Pros

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

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

"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."

"Content filtering is the most useful feature of iboss."

"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."

"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."

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."

More iboss pros

"The solution is extremely stable. It has excellent performance."

"Stability-wise, it's good. I have never encountered any bugs."

"Cisco Talos threat intelligence significantly influences my company's ability to act against emerging threats, giving us the chance to patch our side or take precautions when zero-day vulnerabilities emerge."

"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."

"I have found the malware protection feature valuable. It is helpful and deliverable and is able to protect my entire organization from getting compromised. It also prevents us from visiting any malicious sites which are not visible to the users."

"The reports and notifications are the most useful part of the platform. As soon as you deploy the security layers, the reporting is very comprehensive. It helps you to have, at a glance, a clear view of what's going on."

"I would describe the experience deploying Cisco Umbrella overall as super easy. It was awesome. It was lovely to deploy it."

"I haven't needed to reboot the servers for years due to their excellent stability."

More Cisco Umbrella pros

"Sandboxing, DLP, and SSL inspection engine are the most valuable features of Zscaler SASE."

"The most valuable feature is the manageability of the micro tunnels."

"It is straightforward to set up."

"The best feature is the ability to establish the connection between your public network and automatically connect to the intranet connection."

"Zscaler Cloud DLP provides you with basic DLP features that you get out of the box such as keywords, regular expressions, and data identifiers, for example, your social security numbers, and credit card numbers, with everything built into the product, so you can directly use those features within the policies. You don't need to create it from scratch, and to me, this is the biggest benefit of Zscaler Cloud DLP. You have a lot of templates to choose from in the solution, rather than having to create templates from scratch or reinvent templates."

"Has a good zero trust feature."

"I find all Zscaler Private Access features valuable because each replaces flawed technologies, such as EPAs being replacements for VPN and PR as a replacement for PAM, so I can't mention only one valuable feature. Overall, Zscaler Private Access is a good solution."

"Its impressive scalability allows the combination of multiple dictionaries and using them as one engine, resulting in narrower data loss gaps."

More Zscaler Zero Trust Exchange Platform pros

Cons

"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."

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

"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, obviously, there are bugs."

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

"The dashboards for local use could be better."

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

More iboss cons

"With any Cisco product, it's the licensing side of things that needs improvement."

"I'd like to see this solution more closely integrate with other products Cisco has in its portfolio."

"Its reliability and the response time of the support team can be better."

"I would like for their support to be faster."

"They should provide more integrations and bring things together so that there is a more standard feel to their platform. We also use Cisco ISE, and it has a very different feel from Cisco Umbrella."

"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."

"Cisco Umbrella is difficult to manage and needs to include a dashboard. It needs to improve pricing as well."

"This solution does not give us full, 360-degree protection."

More Cisco Umbrella cons

"It needs to offer SSO, single sign-on, and items of that nature."

"In the next release, I would like to see RE2 Regex supported."

"There could be a feature to view the VPN tunnel activities in terms of configuration."

"The pre-defined dictionaries could be improved."

"Conflicts arise if you do not have the same management teams on the product."

"Another area of improvement is implementation through non-client connectors. The solution can be implemented in two ways. One uses the back file; the other one uses client connectors. So the client connector is pretty fast, but when it comes to non-client connectors and procedures, it's kind of delayed and slow."

"Zscaler CASB should include integrations with other SaaS applications."

"We'd like to have two-factor authentication that is quite simple."

More Zscaler Zero Trust Exchange Platform cons

Pricing and Cost Advice

"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."

"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."

"Its value exceeds its pricing."

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

"The pricing model is easier compared to some of the other solutions, and it is also competitive."

"There are three models for licensing with different feature sets."

"The price is fair, and the licensing cost is based on the number of users. We have seen a good ROI."

"It has a reasonable price. It is certainly not as expensive as it used to be. It is in line with other offerings on the market. There are a number of different flavors of Umbrella. They could bring Umbrella SIG down a bit because its price is a little bit high for what it does, but I also understand why its price is high."

"Cisco Umbrella is expensive and could be cheaper."

"The pricing is great and very competitive with the rest of the market."

More Cisco Umbrella pricing and cost advice

"The technical support is good."

"Zscaler Private Access can be an expensive solution, depending on the license type you will purchase."

"My company is a Zscaler Private Access partner, so the customers pay for the license fees."

"Zscaler DLP solution is expensive, with a fixed pricing structure that is billed annually and monthly. There are no additional costs for licenses."

"There is definitely an ROI."

"The solution has increased prices this year."

"The pricing is quite high, especially when it comes to the gateway."

"Pricing for Zscaler Private Access is moderate. It's acceptable, though I can't give you the exact price currently. It's not too expensive, and on a scale of one to five, I would rate it a four out of five in terms of pricing."
