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.

Email security has protected critical communication but hyperlink handling still needs improvement

We have been using Mimecast Web Security for quite a lot of years. Regarding the analytics part you asked and what metrics are most valuable for monitoring web activities in our case, we am not dealing with the monitoring; that's our MSP who does the majority of the monitoring on our behalf. Regarding the reporting part, I have seen the original reports from Mimecast Web Security, which seem to be quite heavy in terms of information. With the MSP, we are just reviewing and discussing what is necessary. If there is a concern, that is dealt with MSP immediately rather than waiting for formal conversations. However, I think the Mimecast report is fine and easy to read. It is hard for me to say whether the installation is easy or complex, as I wasn't involved; it was done by our MSP. I am the end customer of Mimecast Web Security, not a consultant.

Designed to enforce architecture governance, ensuring traceable SaaS traffic

Netskope provides vigorous policy enforcement for SaaS platforms based on how we configure it, but its vulnerability management and threat intelligence capabilities could be stronger. We rely on external sources to become aware of vulnerabilities in major SaaS platforms, which highlights a gap. It would be beneficial if Netskope offered more robust vulnerability management or integrated threat intelligence through in-house development or partnerships. This would allow for a better policy setup without needing external threat intelligence to configure Netskope. Adding these features would enhance its overall value. I would suggest making some minor improvements to the interface to make it more intuitive, but those are primarily cosmetic. In terms of actual features, the only significant enhancement I could think of, besides better threat intelligence, would be for Netskope to assess the general SaaS landscape. This could include a scorecard showing the security posture of various SaaS platforms based on their track record with breaches and vulnerabilities. I understand this could create friction with SaaS providers if some receive poor scores, which might impact their relationship with Netskope. If Netskope were to harness machine learning more effectively and share those models transparently with enterprise customers, this could include making traffic data they already collect available for deeper analytics, allowing customers to gain better insights into employee traffic patterns. It could also assist with network operations by helping to fine-tune performance based on traffic flow, even though the primary purpose of analyzing that data is security-related. Providing more advanced analytics using existing data could significantly enhance its value to enterprises.

Quotes from Members

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

Pros

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

"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."

"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."

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

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."

"Technical support is pretty sharp and very responsive."

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

"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."

More iboss pros

"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."

"The solution offers good security functionality."

"The solution's CASB, DLP, and threat protection features are very good."

"Overall, the product is nice, and I like the URL filtering, CASB, and other security stacks like threat prevention."

"The solution has some useful features, such as microservices. They have sandboxing that allows the prevention, encryption, and remote browser isolation."

"Web filtering and DLP are good features."

"We've found the solution to be quite stable."

"As Netskope is a cloud-based application, it is possible to analyze and distinguish personal and enterprise instances."

"One of the valuable features of the solution is that everything is on the cloud. It has no on-premise hardware to deal with."

More Netskope Next Gen Secure Web Gateway pros

Cons

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

"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."

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

"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."

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

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

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."

"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

More iboss cons

"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."

"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."

"They should work on marketing material to put out their work with a little more effort."

"Netskope can only provide the high level related to threats."

"Cost competitiveness is its area of improvement. They will have to figure out how can they strategically price it because there are a few players in the game who have been doing it for a long time. They will have to figure out how to go to market on the pricing."

"There is room for improvement in streamlining policies. So what happens is that when you apply a specific Netskope policy, you never know the kind of content it will automatically block, or it will allow."

"Improvement in the solution is required in certain areas where the product does not provide access to its direct end users, who use the portal as an administrator."

"The accuracy could be improved."

"The solution lacks a good reporting feature."

"Since they have the Netskope client, adding some functionality in the endpoint would be good."

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."

"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 not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."

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

"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."

"The price is average. Because the license is user-based, you can increase it as per the user quantity."

"The solution's overall cost is cheaper than regular web security solutions."

"The license model is based on the number of users. You have the possibility to have 10,000 users if you wish."

"We pay a licensing fee of $10,000 on a yearly basis."

"The product is cheap."
