Cisco ACI and Illumio are competing in the network security category, offering distinct approaches to network visibility and segmentation. Cisco ACI often leads with comprehensive integration within Cisco infrastructures, but Illumio offers innovative security features valued by users for their effectiveness despite higher costs.
Features: Cisco ACI offers policy-driven automation, centralized management, and cloud integration, excelling within a Cisco environment. It also supports policy-based routing and integrates seamlessly with virtual environments like VMware. Illumio’s strengths lie in micro-segmentation, real-time application dependency mapping, and providing visibility across diverse network architectures.
Room for Improvement: Cisco ACI could benefit from simplifying its deployment process and reducing the need for Cisco-certified expertise. Enhancing out-of-the-box security features would also be advantageous. Illumio, while strong in security, might improve its tagging policy complexity and provide more comprehensive integration tools for wider network environments.
Ease of Deployment and Customer Service: Cisco ACI is noted for its complex deployment process, requiring certified expertise but benefiting from extensive support resources. Illumio offers a simpler deployment, allowing quick integration and ease of use, with less need for intensive training despite having less comprehensive support resources than Cisco.
Pricing and ROI: Cisco ACI reflects its rich feature set and integration potential with higher costs, offering substantial ROI in large infrastructures. Illumio, with more flexible pricing, appeals to modern environments, often delivering significant ROI through improved security. Cisco's enterprise-level capabilities justify its pricing, while Illumio’s impactful features provide excellent ROI.
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.
The solution offers high performance and scalability with connectivity options up to 100 GS.
You can use the multi-site and multi-pod features, which help you scale the data center over the WAN and create large sites.
The scalability of Cisco ACI supports our organization's growth effectively.
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.
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.
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.
Its features, like easy application deployment, short deployment time for new applications or software, and eliminating the hassle of STP, are appreciated.
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.
