Cisco ACI and Illumio compete in the network management and security sector. Illumio takes the upper hand due to its focus on flexibility and ease of use in diverse environments.
Features: Cisco ACI offers extensive automation and scalability, supporting over 64,000 tenant networks and a million endpoints. It provides multitenancy and smooth integration with VMware, enhancing network efficiency and visibility. Meanwhile, Illumio emphasizes granular visibility, micro-segmentation, and streamlined traffic analysis, which is supported by user-friendly mapping and policy generation features.
Room for Improvement: Cisco ACI struggles with complexity, a steep learning curve, and integration challenges with external systems. The interface complexity and inconsistent technical support add to its issues. Illumio has room to grow with more OS support, improved logging details, and enhanced data security. Its agent-based approach can pose challenges, particularly in OT environments, limiting its flexibility.
Ease of Deployment and Customer Service: Cisco ACI primarily fits on-premises environments with potential for hybrid cloud deployment. Its complexity can hinder deployment speed. Illumio supports both on-premises and public cloud scenarios, offering greater flexibility. Cisco's technical support receives mixed reviews, particularly concerning delays and expertise in newer versions. Illumio’s support is generally more responsive with dedicated teams, though there's room for improvement in training and troubleshooting.
Pricing and ROI: Cisco ACI is perceived as expensive, with high licensing costs and initial investments, yet it offers strong ROI through reduced downtime and improved network management. Illumio provides more flexible pricing models suitable for various scales, remaining expensive but considered cost-effective compared to solutions like Guardicore. However, explicit ROI details are less frequently highlighted by users.
Efficient utilization leads to cost savings and efficiency gains.
Illumio is known to be the cheapest solution among the security solutions we evaluated.
The technical support from Cisco is satisfactory.
When issues occur, the TAC is not able to provide much support, leading to difficulties in finding RCAs.
Even if we raise an issue on non-working days like Saturdays or Sundays, we receive prompt responses.
From my experience, they are very responsive.
Expanding your network or your data center with Cisco ACI is not an issue; scalability is a good feature.
The scalability of Cisco ACI supports our organization's growth effectively.
The solution offers high performance and scalability with connectivity options up to 100 GS.
Scaling it to a large level is not an issue for us.
For stability, Cisco ACI rates a nine or 9.5 because I've seen three customers using Cisco ACI and once deployed, the solution is very stable.
Illumio is a stable solution with no glitches or bugs reported, making it a reliable product for us.
We do not make use of its visibility and analytics features, as we are mostly using it for the networking part only.
Their lack of on-ground offices can result in business losses.
There could also be more examples of how the automations can be done using Illumio.
That's why I'm looking for comparisons with other products.
There should be an option to upgrade from the console to the latest version instead of performing manual upgrades.
In general, Cisco ACI is on the higher side; it's not a cheap solution.
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.
I know that Illumio is the cheapest solution in the security area.
I think it's not very expensive if we compare it with Guardicore.
Cisco ACI provides substantial capability; you can design your network accordingly and it's part of the SDN family, providing many benefits to the organization, especially when moving from traditional network infrastructure.
The current tool is adequate for day-to-day operations, but we want to explore more on AI Ops and hope future versions of OpenText can support that.
It is essential for growing our data center connectivity and enablement for our customers.
Illumio helps in audit purposes by saving data and showing blocked traffic, ensuring no outside traffic is allowed.
The most important feature is the traffic review analysis, where we use the draft view and the reported view that helps us understand how the application interacts with other applications in the environment, and based on that, we are able to define the policies.
The dependency map is the most valuable aspect.
