Zero trust access has strengthened remote connectivity and secures diverse office devices
Appgate SDP support is always available to assist, which is the primary strength. However, there are areas for improvement. When a user is unable to connect, the platform should display detailed information such as the user's IP address, MAC address, and specific reasons for connection failure. Currently, aside from invalid username and password errors, Appgate SDP provides generic errors related to policy, such as a policy admin error. The system should provide deeper diagnostics to explain why a user cannot connect. The dashboard could also be enhanced with additional features and logins to provide better visibility. Sometimes there is no immediate clarity about what is happening. After using Appgate SDP for a long time and experiencing various errors, we have learned where to investigate, but this would be problematic for new users trying to resolve issues. The dashboard could display user connection times, failure reasons, and other relevant information. The user activity logs and accounting features should be improved in particular.

Micro-segmentation has transformed endpoint protection and now isolates internal threats effectively
Illumio can be improved in several areas based on our feedback. Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices. When these devices communicate within the network, loading the map or connections can cause latency, which needs improvement for a more user-friendly and faster experience. Regarding improvements to the interface, I believe we can add more features to the graphical user interface, such as proper logs. While the logs currently indicate what was blocked or allowed, clicking on a specific log should provide more information, such as which extra-scope rule is causing a denial, offering better analysis for troubleshooting.

Quotes from Members

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

Pros

"One of the most important features is stopping lateral movement across our network."
"The interface is really friendly. It's simple to understand."
"The flexibility of the tool is valuable; it is very robust, has a very robust configuration capability, is pretty well documented, and is also good interface-wise."
"It is pretty stable."
"It is a scalable solution...The support answers your questions very fast."
"Appgate SDP is the best solution for micro-segmentation and supplying VPN solutions."
"Appgate SDP has positively impacted my organization, as we are using it to securely access the internet after the cyber attack."
"Previously, with AnyConnect, we experienced frequent issues, and in comparison to that solution, we have seen significant improvement and minimum downtime."
"The features that I have found most useful is the ability to centralize all the rules and then distribute them across various locations. However, I've encountered challenges related to tagging policies, which can be complex to devise. It's a matter that requires careful consideration and stakeholder involvement before implementing such policies."
"It has helped us to understand internal network visibility and firewall policy implementation. We use the product to simplify firewall policy implementation."
"The flexibility of the solution is its most valuable feature."
"The dependency map is most valuable feature."
"Illumio Segmentation has had a positive impact on my organization, as it has created a very impressive impact because it is a worldwide operation."
"The strongest aspect of Illumio is the visual traffic interface, which allows us to see all traffic that communicates with our servers and allied companies."
"One big outcome we saw after implementing Illumio was a notable drop in lateral movement incidents."
"The product provides visibility into how the applications communicate and how the network protocols are being used."
 

Cons

"They could provide a single-box solution to manage tools for 4000 users. Additionally, they could add extra features to enhance remote micro connection."
"One limitation is that it's harder to provide access to multiple applications in the company with Appgate, but that's probably because of poor management."
"One thing that kind of sticks out to me is the ability to do a proper non-split tunnel. VPN tunnel-wise, it is not really a true unsplit tunnel, but I think that's just because of the way it's designed. A split VPN basically allows your system to talk to other systems without being forced down the tunnel. A VPN running in a non-split tunnel mode forces all the traffic down the tunnel to wherever you're VPNing to. It forces the traffic down so that the traffic is subject to the firewall and rules that you have in your corporate environment and such. It helps to prevent remote malicious folks that may be talking directly to that box from piggybacking into the corporate environment through it. They do it partially, but it would be nice to see more of an enterprise-level solution there."
"The user interface should be improved as it is not very easy to work with the updates."
"If I could change or improve anything about Appgate SDP, it would be to enhance the user experience by improving the UI so that it is more explanatory."
"When a user is unable to connect, the platform should display detailed information such as the user's IP address, MAC address, and specific reasons for connection failure."
"One thing that kind of sticks out to me is the ability to do a proper non-split tunnel."
"It would be better to connect to an application portal from any device. Documentation and support could be better."
"We need more details on areas where there is an error or a traffic blockage. I would like the tool to offer a more detailed view."
"The solution is very basic and doesn't do anything other than the orchestration of layer four endpoint firewall rules."
"Illumio can be improved if we have more interactive sessions with the tech team."
"So far, we haven't been too satisfied with the assistance they've provided."
"One area for improvement regarding Illumio might be making the policy management even more intuitive."
"I would appreciate if Illumio Segmentation's interface were better."
"Illumio supports both on-prem and cloud environments, but I think the GUI interface could be more user-friendly."
"It requires a low-level re-architecting of the product."
 

Pricing and Cost Advice

"It is a pretty expensive tool. It is maybe about $20,000 per year for a hundred users or so."
"We pay $100 per user per month. One license for the site is around $17."
"The pricing is according to the market price. It is not a very cheap solution. They have some very aggressive promotions to sell the product in the market."
"The product's pricing is around 10,000-15,000 USD. The pricing is on a yearly basis."
"There is a subscription needed to use Illumio Adaptive Security Platform and we pay every three years. Overall the solution is expensive."
