Cisco ACI and Illumio Segmentation are leaders in network solutions. Cisco ACI often has an edge with its networking capabilities, while Illumio stands out in security features.
Features: Cisco ACI offers centralized management, programmability, and automation with robust networking capabilities. Illumio, however, excels with micro-segmentation, policy management, and real-time traffic control, providing enhanced internal security without altering infrastructure.
Room for Improvement: Cisco ACI requires an easier user interface and broader integration with Cisco products. User feedback also highlights a steep learning curve and occasional technical support issues. Illumio needs enhancements for third-party tool integration, intuitive policy management, and AI-driven automation.
Ease of Deployment and Customer Service: Cisco ACI is complex to implement, suited for large environments, with deployment challenges somewhat mitigated by robust technical support. Illumio emphasizes easy deployment across on-premises and cloud setups yet calls for better customer service responsiveness.
Pricing and ROI: Cisco ACI is a high-investment solution, often justified by operational savings and strong ROI through reduced downtime. Illumio's flexible subscription pricing is more cost-effective than some competitors, offering significant ROI through efficient security improvements and risk reduction.
Efficient utilization leads to cost savings and efficiency gains.
I observe extensive return on investment with Illumio.
Illumio serves as a single endpoint technology where I can implement various features, including a zero-trust network, north-to-south and east-to-west configurations, and micro-segmentation, all coming from one platform, which ultimately saves us time and money.
Illumio definitely demonstrates its value in money-saving capabilities, enhancing our lateral environment inside the organization and providing effectiveness overall once integrated.
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.
Whenever I raise a case with their support team, regardless of the priority level—P1, P2, P3, or P4—they generally reply within an hour
Even if we raise an issue on non-working days like Saturdays or Sundays, we receive prompt responses.
The customer support is very prominent.
The solution offers high performance and scalability with connectivity options up to 100 GS.
The scalability of Cisco ACI supports our organization's growth effectively.
Expanding your network or your data center with Cisco ACI is not an issue; scalability is a good feature.
Scaling it to a large level is not an issue for us.
By employing Linux scripting or other methods, I can push the policy to all devices at once, making it easy to scale.
Illumio's scalability is very good; it is quite easy to scale.
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.
We do not make use of its visibility and analytics features, as we are mostly using it for the networking part only.
They need to install an agent in the container world, while Akamai Guardicore does not need to install an agent, so they have native support that Illumio lacks.
There could also be more examples of how the automations can be done using Illumio.
Another improvement might be around scalability, ensuring that as organizations grow, Illumio can handle even larger, more complex environments seamlessly.
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.
But when you compare it to firewalls, then it may not be that expensive.
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.
Illumio is a powerful tool for micro-segmentation and zero trust security that provides strong visibility, flexible policy management, and effective threat containment, enhancing an organization's internal security posture.
