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.

Zero-trust access has improved remote security and now simplifies cloud-based firewall management

Regarding the integration part for Prisma Access by Palo Alto Networks, the integration with identity providers is pretty much good. It is basically firewall as a service, so it performs well. I completed the integration without any issues. What Palo Alto Networks can do better for Prisma Access by Palo Alto Networks is probably to have the point of presence available in more locations. The point of presence from the Serbia region has the nearest POP in Frankfurt, which is an issue since it is your gateway—when you start browsing the internet, you go through a commercial connection in Germany. They definitely need to spread the service in other countries.

Quotes from Members

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

Pros

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

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

"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."

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

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

"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."

"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."

More iboss pros

"Prisma Access protects all app traffic, so that users can gain access to all apps and that's very important because we need to be able to access everything. It also allows us to access non-web apps; anything internal that we need access to, we can access."

"Its hands-off security and the fact that we don't have to maintain it are the most valuable features."

"Prisma Access by Palo Alto Networks is a seamless solution."

"This solution provides a DLP on the cloud and very few people have a scanning device for data at rest."

"The solution improved the consistency of our security controls and the BCP. There has been a 20 percent reduction in TCO. Prisma Access also enabled us to deliver better applications by centralizing security management."

"It has predefined or preconfigured rules, which are getting periodically updated. They are providing continuous improvements and periodically updating all search queries that they are looking for. That is one thing that helps us to stay vigilant and focused. If we query our AWS account for any breaches or vulnerabilities with any of the cloud tests, and it alerts us based on these predefined rules. It also provides an option to configure our own rules, and based on these rules, it can query the cloud trail logs, pull the information, and trigger alerts in real-time. I haven't explored this feature much because there are multiple accounts, and we don't have enough time to explore this feature. It also provides multiple integrations. When vulnerabilities or breaches are happening, you should be aware of them immediately. It provides integration with tools such as Slack, PagerDuty so that you can get alerted as soon as the high severity stuff comes up. For example, you have a security group that has allowed public traffic on port 22. As TechOps, you should be aware of this immediately. You cannot scan each machine or look into all security groups to identify it. So, Prisma helps us and alerts us when this kind of high-priority stuff comes up. It has different statistics, analytics, and graphs for data. The description of alerts is also pretty good. They describe what are the possible causes for this and what are the solutions. From Prisma Cloud, you can directly go to the AWS account. When you click on an alert, a resource, or a resource ID, it takes you to the AWS console where you need to log in. If you are already logged in, it will take you to that instance directly, and you can fix the issue there. I have found this feature very useful."

"Its frontend is user-friendly. It is easy to use for us."

"A feature I've found very helpful is run time security because most of the products on the market will look at security during the build time, and they don't really look at what happens once you're going into production."

More Prisma Access by Palo Alto Networks pros

"Zscaler B2B provides significant security benefits by reducing attack surfaces through Zero Trust Network Access (ZTNA) implementation."

Cons

"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."

"The reporting feature needs improvement."

"The dashboards for local use could be better."

"Our iboss subscription access should be more secure with an OTP or VPN etc. It is easy to gain access if, for example, hackers obtain my username and password."

"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."

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

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

"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

"The price can be reduced to make it more competitive."

"The frequency of updates could be reduced."

"Palo Alto Prisma 10 came out over a year ago. Palo Alto added this identity management feature. The legacy way Palo Alto selected which user is sitting on an IP address it passes through has been clunky."

"The BGP filtering options on Prisma Access should be improved."

"They automatically update and they should give us time to fully understand what they're updating so that we can make sure it doesn't impact production."

"We've run into some challenges, having hit a lot of bugs over the past year in the deployment of GlobalProtect. We've had our fair share of issues that I haven't been happy with. We're working with the support organization to remediate them and waiting for updated releases. The response on getting the bugs fixed has not been what I would consider adequate for a product like this."

"The product's current price is an area of shortcoming where improvements are required."

"They can add some new characteristics. For example, when an incident triggers, they can automatically send a template for a particular match that is related to the policy. We don't have that right now. It is something to improve. There could be more automation for certain actions. For example, for a particular group, it can send an administrator alert to their manager. It was one of the concerns of our customers."

More Prisma Access by Palo Alto Networks cons

"Some areas for improvement include the SSL inspection, as decrypting and inspecting encrypted traffic induces latency."

Pricing and Cost Advice

"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."

"It is expensive compared to one of its competitors."

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"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."

"It is a little expensive. Because it is one of the best in the market, it is a little bit more expensive than other vendors."

"It's pricey, it's not cheap. But you get what you pay for."

"The price has been good for the ROI during these difficult times for the cruise industry. There are no hidden costs; what the product offers is what you get."

"It is not cheap. It is expensive. The good thing is that you are able to pay for what you need, but overall, it is not cheap. The pricing is not based on packages. You pay based on the features. If you want DLP, you only pay for DLP. They are very flexible. It is not cheap, but the licensing is flexible. There are no additional costs in addition to the standard licensing fees."

"This is not an expensive product and everything is included with one license."

"Prisma Access by Palo Alto Networks has flexible licensing models with different categories. It comes with different features which can be removed if not needed. However, its pricing is high."

"Actually the solution is very expensive. I don't know the particulars since the purchasing team dealt with it."

"The solution requires a license and the technical support has extra costs. The licensing model could improve."

Reviews from Real Users

Below are some reviews and helpful feedback written by Microsoft Azure Synapse Analytics

users who are currently using the solution.

PeerSpot user Partha D., Global Network Tech Lead at a computer software company, speaks about his experience using the product, saying, "It protects all app traffic so that users can gain access to all apps. Unlike other solutions that only work from ports 80 and 443, which are predominantly for web traffic, Prisma Access covers all protocols and works on all traffic patterns... The most sophisticated attacks can arise from sources that are not behind 80/443."

Tejas J., a Sr. Cloud Security Architect at a computer software company, mentions that "it is geographically dispersed, and it sits on top of Google and AWS platforms. Therefore, you don't face the standard issues, such as latency or bandwidth issues, that you usually face in the case of on-prem data centers.”

Another PeerSpot reviewer, Max I., Associate Director at Cognizant, comments that "Security is absolutely spot-on, really top-notch. It's the result of all the components that come together, such as the HIP [Host Information Profile] and components like Forcepoint, providing end-user content inspection, and antivirus. It incorporates DLP features and that's fantastic because Prisma Access makes sure that all of the essential prerequisites are in place before a user can log in or can be tunneled into."
