Segmentation of legacy systems has protected outdated endpoints and reduces network risk

The best features Akamai Guardicore Segmentation offers make it simple to see all of the connections that are being made to each of the endpoints, and they can be controlled by process and port. The ability to control by process and port helps my team day-to-day because, since there are hundreds of thousands of connections to some of these endpoints, looking at the Reveal Map makes it simple to audit and create rules for what we want to allow. Akamai Guardicore Segmentation has impacted my organization positively because we find it difficult to remove the legacy systems, so it was very important to segment them from the rest of the network to protect them and protect the rest of our network.

Has enabled consistent enforcement of zero-trust policies at the virtual layer

The micro-segmentation feature helps to manage network security effectively because it helps the virtual machines that are already on the cluster and the applications inside the cluster itself. It protects them and helps them communicate with each other without needing a complex external or internal firewall in this use case. Working with the zero-trust security model means never trust but always verify. Every VM, application, and service in your environment must explicitly prove it's allowed to communicate with others. An application would be able to talk to a VM and vice versa. This zero-trust means explicitly proving that they are allowed to talk to each other, with no implicit trust just because they are on the same VLAN, subnet, cluster, or environment. Nutanix Flow brings the zero-trust model natively to the virtual layer inside the Nutanix software itself, the AHV. The AHV software enforces strict communication rules between workloads. Integration between Nutanix Flow and other products natively benefits the infrastructure itself as this is a networking segmentation software coming from Nutanix itself. This provides ultimate compatibility. There is no need for extra firewall VMs such as Palo Alto or third-party switches. Security becomes established at the hypervisor level, which creates a new conglomeration of security segmentation. The network performance analysis that Nutanix Flow Network Security provides is very beneficial and effective.

Quotes from Members

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

Pros

"Guardicore makes its own rule set automatically, so we can work fast when creating a rule set."

"This tool greatly helps in understanding the footprint of the attacks."

"I found the solution to be stable."

"Initially, I liked the telemetry part. But later, we used the microsegmentation features that we were able to deploy and found that they really stood out from other vendors. It allows us to see microsegmentation as distributed services."

"From day one, you get threat intelligence. It will immediately block active threats, which has been useful."

"The real bonus is the fact that we can secure applications, all the way down to the individual services, on each host. It's actually more granular security than we can get out of a traditional firewall."

"Application Ring-Fencing and Deception Server, which is basically like a honeypot, are pretty useful features."

"The most valuable feature is the visibility of processes and connections."

More Akamai Guardicore Segmentation pros

"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."

"The network view was excellent as it allowed us to expand the server view and visualize all connections it made within the environment. This was particularly useful in identifying the path of our data and not just its location within the data center."

"The micro-segmentation feature helps to manage network security effectively because it helps the virtual machines that are already on the cluster and the applications inside the cluster itself, protects them and helps them communicate with each other without needing a complex external or internal firewall in this use case."

"Nutanix Flow has a lot of data protection features. It's also valuable for operations and management. It's a big solution that works well with different solutions and is suitable for most business cases."

"Flow Network Security's most valuable features are user-friendliness, the console, and policy creation."

"They also introduced that they develop API first and the rest follows."

"Nutanix Flow is straightforward to install. You only need to select a checkmark that you want to enable Nutanix Flow."

"We appreciate the fact that this solution allows us to segregate two virtual machines that are in the same cluster."

Cons

"In our version, when using the terminal server, we cannot exclude user tasks for each session."

"The dashboard needs improvement. It should be more flexible so that I can easily see what I want or need to see."

"It would be very helpful for beginners if the solution had more windows to help with the terms inside instead of going to the documentation."

"Clients would like to see that the security policies of GuardiCore can continue to be comparable to all the major firewall players out there."

"Akamai Guardicore Segmentation can be improved because keeping it up to date is difficult since it is SaaS-based and updates are not on a regular schedule; I have to reach out to my contact to ask them to update to a newer version, and it would be helpful if updates were on a regular cadence so that I would not have to remember to ask them."

"Kubernetes is not installed in the way we need it."

"The product needs a few features like enhanced user policies and payload-level inspection to improve the offering."

"Needs more customization of honeypots and a vaster catalog of systems able to be mimicked."

More Akamai Guardicore Segmentation cons

"The documentation offered by the product is an area with certain shortcomings where improvements are required."

"Last time I used it, it was not handy to see or to analyze traffic logs."

"The most difficult part is the configuration of the initial blueprints."

"The solution’s pricing could be improved."

"Nutanix Flow's networking features could use some improvement. Also, I don't know if it's currently supporting load balancing or not."

"We would like the reporting functionality of this solution to be improved."

"Nutanix Flow Network Security needs to improve threat hunting, compliance, and policy optimization - these things that security officers would use."

"For customers who are running Nutanix Flow and AHV, the largest area for improvement is in the disaster recovery environments. To automate the populate of rules from one side to the other side in case of disaster you report everything on the disaster recovery site, and you have all the rules automatically applied. This was something that was being built when I left Nutanix. It might already be available. Additionally, the usability of the rules editor could improve."

Pricing and Cost Advice

"GuardiCore has made some new changes to the license now. We've seen monthly and annual licenses based on a subscription. We have a few clients that pay anywhere from $25,000 a year."

"This is not a cheap solution but you have to consider the bigger picture, which is what it is giving you."

"Compared to the pricing we were seeing from both Illumio and Edgewise, Guardicore was very competitive."

"The pricing is too high."

"The solution is reasonably priced and I would rate it a six out of ten. The tool's licensing costs are yearly."

"The customer would complain about the cost."

"Guardicore Centra provides better value for money than NSX, was the other solution that we looked at, which was too expensive for what it does."

"Akamai Guardicore Segmentation is expensive."

More Akamai Guardicore Segmentation pricing and cost advice

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a seven out of ten."

"Flow Network Security is available on a three-year license, with annual renewals of the maintenance fee."

"The product is available for free use."

"There are different licensing models."

"In comparison to other options available in the market, I would rate their pricing as very competitive, probably a two or three out of ten for cost."

"This model is very accessible to implement."

"There is an annual subscription to use this solution. There is a 60-day trial to use the solution, it gives you time to decide if you want to continue using the solution."
