What is our primary use case?
When we onboarded Cisco Secure Workload, the usual use case was to discover internal application dependencies and create a dependency map for Cisco ACI. As the network team, we chose to implement ACI in a network-centric mode rather than an application-centric mode. However, we soon realized that Cisco Secure Workload's capabilities extend far beyond discovering dependency maps.
We use it for internal micro-segmentation. After evaluating it, we began using the agent-based solution across our server estate to protect our internal servers from each other and internal users. Today, our primary use case for the product is micro-segmentation within our internal network.
How has it helped my organization?
Cisco Secure Workload is an agent-based solution that allows you to install the agent on physical servers and virtual machines in your own data center and on VMs in cloud environments like AWS, Oracle Cloud, or Azure. This flexibility is a key advantage over other solutions, such as NSX-based products, which may be tied to specific vendors or technologies.
With Cisco Secure Workload, we can effectively implement micro-segmentation regardless of where the application resides, whether in the cloud or on-premises. This solution enables us to segregate the entire application estate, including servers, databases, and user access, using the agent-based micro-segmentation capabilities of Tetration. The Tetration Agent leverages the local firewall on the operating system, whether it’s the Windows Firewall or a Linux firewall on a VM.
What is most valuable?
The most valuable feature of Cisco Secure Workload is its ability to streamline policy discovery. Once you create the workspace, it automatically identifies policies at various levels, whether you need finely-tuned micro-level or broader group policies. As data is gathered from all the agents, the system presents these policies, significantly reducing the need for multiple engineers who typically take much longer to create them. My IT risk colleagues utilize a process we call ADM, where they discover policies over a three to six-month period and present them to application owners. Once the application owners approve the policies, they can switch to enforcement mode in Cisco Tetration. This automation in policy presentation and access is incredibly valuable, as it minimizes manual intervention and the time required for policy discovery.
Micro-segmentation allows for precise enforcement of policies based on specific needs. You can implement tight risk postures, defining policies per IP, server, or port. This enables granular control or broader policies at the group level, grouping similar types of servers. The system automates this process; you specify your risk appetite and how detailed or general you want the policies to be. This approach protects servers that sit next to each other on the same VLAN without requiring large network firewalls to create multiple dependencies or DMZs. Instead, it leverages the existing firewalls on each server, allowing you to control policies centrally.
What needs improvement?
We actively seek improvements in integrating the Infoblox DDI platform with Cisco Secure Workload. This integration allows Cisco Secure Workload to learn about our networks and network tags, providing valuable insights into vulnerabilities related to the operating system and various applications installed on our servers.
Recently, Cisco announced a new product called HyperShield, an AI-based autonomous micro-segmentation solution. While Cisco has not stated that HyperShield will replace Cisco Secure Workload, it represents a natural evolution for the company. HyperShield features dynamic policy discovery and enforcement; however, once policies are enforced, they do not change until a discovery occurs, requiring a re-enforcement process. This new platform operates autonomously, minimizing the need for user or security engineer intervention.
I would have expected Cisco to incorporate more automatic discovery and enforcement features within the existing Cisco Secure Workload product. Instead of enhancing the current product, they have introduced a new solution. Cisco plans to honor existing Tetration licenses, allowing users to transition to HyperShield without additional costs, reflecting the investment enterprises have already made.
From Cisco’s perspective, this represents a natural progression in their product line. While the product name changes, it seems more of a rebranding effort. The enhancements are greater autonomy, improved discovery, and automatic enforcement, which are now being introduced in HyperShield.
Cisco Secure Workload offers automatic policy enforcement but cannot adjust policies dynamically as the application needs to change. Having used the platform for the past five years, the recent announcement has been reassuring. Cisco has confirmed that our investment in the platform will not go to waste. They will honor our existing licenses, providing a natural migration path to the new solution without any disruption
For how long have I used the solution?
I have been using Cisco Secure Workload for five years.
What do I think about the stability of the solution?
The product is stable. It serves as a management plane for firewall policies. The local operating system firewalls on servers—whether Windows or Linux—are quite stable since they are integrated into the operating system. Policy enforcement control relies on these built-in firewalls.
If the Tetration platform goes down, the server usually functions, and the enforced policies remain active. The only impact of a Tetration outage would be on our ability to push changes or updates. Tetration acts as a centralized policy management tool, contributing to its stability.
I rate the solution’s stability a ten out of ten.
What do I think about the scalability of the solution?
We have seven to eight people using this solution. We were initially licensed for 5000 servers but haven't deployed all those licenses. For our contract renewal this year, we've opted for a 1200 license.
I rate the solution’s scalability an eight out of ten.
How are customer service and support?
Cisco's technical support has always been quite reliable since Cisco manages our rack. Whenever there was an issue, whether it involved replacing a switch or a physical server in a cluster, their support was helpful, and all replacements were completed on time.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
We considered tools from Nutanix and ESX but decided to move away from ESX due to its vendor-specific nature. Each tool had its challenges, especially if we were to invest in a Nutanix solution. We wanted to avoid being locked into a single vendor's ecosystem. We quickly evaluated and eliminated those solutions, as we needed a technology-agnostic option that could operate across all our platforms.
How was the initial setup?
The concepts can be quite new without the right professional services support from Cisco, and security teams might struggle. Cisco's professional services team guided us through the process, helping us implement around twenty critical applications within the micro-segmentation framework.
Our deployment was straightforward. We simply connected two network cables and assigned some IP addresses, and the platform was operational within a day or two. However, the micro-segmentation of each application and the automatic discovery of rules took about a year to fully deploy for all twenty applications.
The process involved collaboration between two teams: the network team, which manages the Tetration platform, and the IT risk team, which focuses on policy decisions. We maintained the Tetration platform, handled updates, and engaged our IT risk colleagues to determine which IT risk policies needed implementation for various applications. They maintained a list of critical applications that required segregation.
Once we established this partnership, the IT risk team worked with application teams on auto-discovery and policy presentation. After deliberation and agreement on the policies, the network team enforced them. Our role primarily involved overseeing Tetration as a secure on-premises platform while assisting our IT risk colleagues, who were still learning, with decision-making supported by Cisco Professional Services.
At the senior management level, we decided which applications to include within the scope of Cisco Tetration. The process was structured to involve one application team at a time, helping them build confidence through testing. Once successful on day one, we deployed the application into production and established policies for service and request flows.
We also implemented a process for handling changes at the application level, using ServiceNow for requests to modify existing policies, similar to changing firewall rules. Additionally, we created a RACI matrix to clarify responsibilities: defining who was accountable for deploying agents, monitoring their performance, and managing policy enforcement.
I would rate the experience a ten out of ten.
What's my experience with pricing, setup cost, and licensing?
CloudStrike offers antivirus capabilities and firewall features for servers and VDI but lacks automatic policy discovery. This raises questions about the resources required to discover and write policies manually. You’d have to consider how many engineers would be needed to manage this process, potentially increasing your team size from two to ten.
I rate the product’s pricing a six out of ten, where one is cheap, and ten is expensive.
What other advice do I have?
We need two people, one from the IT risk side and one from the network side, for the maintenance.
Since deploying the Cisco Secure Workload, we haven't experienced any security incidents with our internal critical systems. While this implementation has increased our maintenance costs due to introducing a new product, it was necessary to meet internal segregation regulations. Without Cisco Tetration, we would likely have been forced to purchase multiple firewalls and create various DMZs, which would have consumed significant time and resources in networking and security maintenance. Traditional hardware solutions wouldn't have offered the same flexibility as Tetration, which allows us to use distributed firewalls on each server.
Deploying this platform across 20 applications has been much quicker than relying on physical firewalls, which would have led to a more macro-segmentation approach.
Overall, I rate the solution a ten out of ten.
