The node that enables Cisco ISE to share contextual information on a device with Cisco Stealthwatch is the pXGrid Controller. The pXGrid Controller is a component of the ISE Policy Service Node (PSN) that facilitates the exchange of contextual data between ISE and other security products, such as Stealthwatch, via the Platform Exchange Grid (pxGrid) protocol. The pXGrid Controller acts as a broker that registers, authenticates, and authorizes pxGrid clients, and allows them to publish and subscribe to topics of interest. For example, Stealthwatch can subscribe to the Session Directory topic to obtain user and device information from ISE, and use it to enrich the network flow data and provide better visibility and security analytics. Stealthwatch can also publish topics, such as Rapid Threat Containment (RTC), to allow ISE to take mitigation actions on compromised endpoints, such as quarantine or re-authentication. References:

 The discovery process is a critical phase in the sales cycle, where the SE gathers information about the customer’s network environment, business goals, challenges, and needs. The discovery process helps the SE to understand the customer’s pain points, identify opportunities, and propose solutions that align with the customer’s objectives and address their problems. The discovery process also helps the SE to establish credibility, trust, and rapport with the customer, and to map Cisco innovation to the customer’s needs.

Some of the activities that should occur during the SE’s discovery process are:

Gathering information about the current state of the customer’s network environment. This includes collecting data about the network topology, devices, protocols, applications, performance, security, availability, scalability, and management. The SE can use various tools and methods to gather this information, such as interviews, questionnaires, surveys, audits, assessments, and network analysis tools. Gathering information about the current state helps the SE to understand the customer’s existing network capabilities, limitations, and gaps, and to benchmark the network against best practices and industry standards12

Mapping Cisco innovation to the customer’s needs. This involves identifying how Cisco products, solutions, and services can help the customer achieve their desired outcomes, address their challenges, and overcome their pain points. The SE can use various tools and methods to map Cisco innovation to the customer’s needs, such as value proposition, business case, return on investment (ROI) analysis, proof of value (POV), proof of concept (POC), and demonstrations. Mapping Cisco innovation to the customer’s needs helps the SE to show the value and benefits of Cisco solutions, differentiate Cisco from competitors, and influence the customer’s decision making34

When demonstrating Cisco Software-Defined Access (SDA), it's essential to tailor the presentation to highlight the strategic benefits and overall architecture without overwhelming the audience with excessive technical details. Two key recommendations for a successful SDA demonstration are:

Keep the demo at a high level (Option B):It's crucial to keep the demonstration focused on the overarching concepts and benefits rather than delving into the intricate technical details. This approach ensures that the audience, which may include decision-makers and non-technical stakeholders, can easily grasp the value and advantages of SDA. By presenting at a high level, you can effectivelycommunicate how SDA simplifies network management, enhances security, and supports digital transformation initiatives.

Show the customer how to integrate ISE into DNA Center at the end of the demo (Option E):Integrating Cisco Identity Services Engine (ISE) with Cisco DNA Center is a pivotal aspect of the SDA solution. Demonstrating this integration towards the end of the presentation allows you to showcase the seamless interoperability and added security benefits that ISE brings to the SDA environment. This part of the demo highlights how ISE enhances network access control, policy enforcement, and overall security management within the SDA framework.
