Cisco ACI needs interface improvements, enhanced training, better integration, improved scalability, user-friendly tools, and stronger technical support.
In large environments, understanding all application dependencies and creating the right policies can take time and requires close coordination with application teams.

I think it is really valuable to take a course on Akamai Guardicore Segmentation because many things are not obvious in terms of how to do them correctly.
Senior Security Analyst at a retailer with 5,001-10,000 employees
The price of Akamai Guardicore Segmentation is very expensive, but it is important to the enterprise.

What we need is something called RAG, or retrieval-augmented generation. If Cisco can implement that to utilize customer-specific data instead of general knowledge, while ensuring data privacy under GDPR laws, I think that will result in very good, reliable output.

Their lack of on-ground offices can result in business losses.
Chief Technology Officer at Mehbub General Trading PLC
We do not make use of its visibility and analytics features, as we are mostly using it for the networking part only.

Cisco's pricing tends to be on the higher end compared to other vendors.

Cost is one thing that could be improved, as it is heavy for an emerging market like ours.

Featured Reviews

Vibin Thomas - PeerSpot reviewer
Technical Team Lead - Content Security at Valuepoint Systems
Zero-trust micro-segmentation has strengthened security and improves east-west traffic visibility
While Akamai Guardicore Segmentation is a very powerful solution, there are a few areas where it could be improved. One of the main challenges is the initial deployment and policy design complexity. In large environments, understanding all application dependencies and creating the right policies can take time and requires close coordination with application teams. The user interface and policy management can also be improved. As the number of policies grows, managing and organizing them becomes slightly complex. A more simplified or intuitive policy structure would help operational teams. Another area is integration with other security tools such as SIEM or SOAR platforms. While integration is possible, making it more seamless and easier to configure would add value. Additionally, the reporting and dashboard could be enhanced to provide more customizable and business-level insights, especially for management and reporting. One small improvement I would suggest for Akamai Guardicore Segmentation is having more automation capabilities for policy creation and recommendation. For example, AI-driven suggestions based on observed traffic patterns would help reduce manual effort during the initial policy design. It would also help to have more predefined templates for common use cases, especially for industries such as banking, to speed up deployment. Another area is enhanced reporting customization where we can easily generate business-level dashboards for management and compliance teams without any additional effort.
Sulaiman Olubiyi - PeerSpot reviewer
Senior Network Automation Engineer at a outsourcing company with 1,001-5,000 employees
Network automation has simplified secure multi-site connectivity and reduced daily operational effort
I believe Cisco ACI could improve by incorporating something related to agentic AI, where it can execute tasks based on particular evaluations or loop engineering, enhancing fault identification or suggestions based on each tenant's configuration. Additionally, I think they should ensure that the documentation is comprehensive. I appreciate that Cisco provides documentation, and their support engineers are helpful in case of any issues. In terms of governance and security regarding Cisco ACI's AI capabilities, I think what we call evals or evaluations is important, whereby the engineer can evaluate the functionalities of the AI in Cisco ACI, preventing it from making deletions or modifications on its own. Therefore, there should be evaluations or guardrails incorporated into the development capabilities. Regarding accuracy and reliability of output for Cisco ACI's AI capabilities, it hasn't met my expectations. What we need is something called RAG, or retrieval-augmented generation. If Cisco can implement that to utilize customer-specific data instead of general knowledge, while ensuring data privacy under GDPR laws, I think that will result in very good, reliable output.
