Cisco Live 2026: Five Takeaways from a Network Engineer 

The device management takeaway 

Cisco Cloud Control 

One of the major themes at Cisco Live 2026 was Cisco Cloud Control, which appears to be Cisco’s long-term strategy for bringing together what have traditionally been separate management platforms such as Meraki Dashboard, Catalyst Center, Intersight, Security Cloud Control, and Splunk Observability. 

The value I see in Cloud Control is not simply another management portal, but a common operational platform that provides a single view of inventory, topology, telemetry, security events, and lifecycle information across the environment. Cisco’s vision is to provide a single management experience across networking, security, compute, observability, and collaboration. 

What stood out to me was the focus on AI-assisted operations. Cisco refers to this as “AgenticOps.” Rather than engineers manually collecting information from multiple tools, Cloud Control is designed to correlate data, make recommendations, interact with TAC, automate workflows, and in some cases perform approved remediation actions. 

Cisco emphasized that this is not limited to Cisco infrastructure. They demonstrated integrations with AWS, Microsoft Azure, Google Cloud, ServiceNow, PagerDuty, Slack, and numerous other vendors. Cisco stated that they currently support more than 50 integrations and are continuing to expand the ecosystem. During a World of Solutions demonstration, I was surprised to see Palo Alto firewalls included as part of the workflow. 

Another feature that generated significant interest was AI Canvas, a collaborative workspace where engineers and AI agents work from the same operational context. The goal is to preserve troubleshooting history, findings, and recommendations as issues move between teams, shifts, or support organizations. 

Cloud Control also allows organizations to create custom AI agents tailored to their own operational processes. For example, a network operations team could develop a WAN Operations Agent that monitors circuit utilization, reviews IPSLA performance, tracks BGP state changes, and automatically opens incidents when service levels are violated. This moves beyond a generic AI assistant and allows organizations to build workflows around their own standards and operational procedures. 

Overall, my takeaway is that Cisco is attempting to create a common operational platform that unifies management, automation, observability, and AI-driven operations across both Cisco and third-party technologies. 

Cisco IQ 

Cisco IQ was presented as a complementary platform focused on providing intelligence, recommendations, and lifecycle guidance rather than day-to-day infrastructure management. 

The primary objective of IQ is to help organizations move from reactive operations to proactive and ultimately predictive operations. It continuously evaluates infrastructure lifecycle status, software exposure, operational risk, security posture, and emerging concerns such as quantum-readiness. 

The practical value for engineers is that IQ can identify devices approaching end of support, software versions with elevated vulnerability exposure, or operational trends that may increase risk. It can also provide recommendations based on broader industry experience and peer benchmarking data. 

What I found particularly interesting is how IQ can work alongside Cloud Control. IQ identifies and prioritizes risks, while Cloud Control can help execute the remediation. For example, IQ may identify a group of devices running software with known vulnerabilities or approaching end of support. It can then recommend an upgrade strategy, identify affected devices, generate a workflow, initiate change processes, coordinate upgrades, and validate compliance afterward. 

My takeaway is that Cloud Control focuses on operating the environment, while IQ focuses on understanding risk, planning improvements, and helping organizations make informed decisions before issues become outages. 

The Architecture takeaway 

Silicon One Architecture 

Another recurring theme throughout Cisco Live 2026 was the evolution of Cisco’s Silicon One architecture and how it is being incorporated across both Nexus and Catalyst platforms. 

Several sessions focused on the internal design of the ASICs, including concepts such as slices, shared forwarding resources, pooled buffering, and packet forwarding across the fabric when required. While these topics can become highly technical, my primary takeaway was not the specific implementation details but the architectural direction Cisco is taking. 

Historically, ASIC design often involved allocating fixed resources to groups of ports or forwarding functions. As traffic patterns became more dynamic, particularly with the growth of east-west traffic and large-scale data processing workloads, those fixed allocations could create inefficiencies and hotspots. 

Cisco’s Silicon One architecture is designed to make better use of shared forwarding and buffering resources across the switch. By pooling resources and allowing traffic to be processed more dynamically, the platform can better accommodate bursts, uneven traffic patterns, and increasingly demanding workloads. 

Cisco frequently connected these capabilities to what they refer to as the “AI-ready network.” My interpretation is that AI workloads are driving requirements for significantly higher bandwidth, lower latency, greater telemetry visibility, and more efficient handling of large east-west traffic flows. The underlying silicon architecture is being designed with those requirements in mind. 

What I found particularly interesting is that these architectural improvements are not limited to environments running AI workloads. The same capabilities that benefit AI clusters also improve performance and operational visibility for traditional enterprise networks. Better buffering, more efficient forwarding, increased telemetry, and improved resource utilization can positively impact any environment experiencing traffic bursts, application growth, or increasing operational complexity. 

In practical terms, organizations may never deploy an AI cluster in their data center, yet still benefit from the engineering investments Cisco is making in Silicon One. The architecture provides a foundation for higher-performance switching, greater scalability, and more detailed operational visibility regardless of whether the network is supporting AI applications or traditional enterprise workloads. 

My overall takeaway is that Cisco is not simply building networking hardware for AI. They are modernizing the underlying network architecture so that it can efficiently support both today’s enterprise applications and the traffic patterns expected from future AI-driven environments. 

The Security Takeaway 

Post-Quantum Cryptography and the Harvest Now, Decrypt Later Threat 

Another topic that appeared repeatedly throughout Cisco Live 2026 was post-quantum cryptography (PQC). While quantum computing often feels like a future concern, Cisco’s message was that organizations need to begin preparing now because of what is known as the “Harvest Now, Decrypt Later” threat. 

The concern is not that attackers can break today’s encryption algorithms today. Rather, adversaries may already be collecting and storing encrypted data with the expectation that future quantum computers will eventually be capable of decrypting it. Information that remains sensitive for many years, such as intellectual property, government records, healthcare data, financial information, and critical infrastructure documentation, may already be at risk even if the actual decryption capability does not exist yet. 

This reality is driving a much more aggressive migration timeline than many organizations initially expected. The challenge is not simply replacing an encryption algorithm. Organizations must first identify where vulnerable cryptographic algorithms are being used throughout their environment and then develop a migration strategy for certificates, VPNs, PKI infrastructure, authentication systems, applications, and network devices. 

Cisco emphasized that the migration to post-quantum cryptography will likely take many years. As a result, organizations that wait until a cryptographically relevant quantum computer exists may find themselves significantly behind the curve. 

For network engineers, this transition will become increasingly relevant to everyday operations. Historically, cryptography was often viewed as primarily a security or PKI team responsibility. However, modern networks rely heavily on cryptographic functions including VPNs, TLS, HTTPS management access, certificate-based authentication, SD-WAN overlays, wireless security, and infrastructure trust relationships. 

As vendors begin implementing post-quantum cryptographic algorithms, network engineers will need to understand which devices support the new standards, how hybrid cryptographic modes operate, and what impact larger key sizes and certificates may have on network infrastructure. Asset inventory, software lifecycle management, and cryptographic visibility will become increasingly important as organizations work to identify systems that require remediation. 

My takeaway is that post-quantum cryptography is less about preparing for a distant technological breakthrough and more about beginning a long-term migration effort today. The organizations that start building cryptographic inventories, understanding dependencies, and planning migration strategies now will be in a much stronger position than those that wait until quantum computing becomes an immediate operational concern. 

The biggest lesson wasn’t “RSA is dead.” The biggest lesson was that most organizations don’t actually know where cryptography is being used in their environment. 

As network engineers, we’re often responsible for: 

• IPsec tunnels  

• SSL VPNs  

• SD-WAN control planes  

• RADIUS/TACACS certificates  

• Switch and router management certificates  

• Wireless authentication  

• PKI dependencies  

The first phase of the quantum transition isn’t replacing algorithms—it’s discovering all the places those algorithms exist. Cisco seemed to be emphasizing that cryptographic inventory and visibility are becoming operational requirements, not just security requirements. That is a message likely to resonate with infrastructure teams because it directly affects network lifecycle management and upgrade planning over the next decade. 

The AI-Ready takeaway 

AI-Ready Networks 

Artificial Intelligence was impossible to ignore at Cisco Live 2026, with nearly every major announcement tied in some way to AI, automation, or AI-assisted operations. While many large enterprises are already exploring AI-driven workflows and agentic operations, my takeaway is that most organizations are still in the early stages of understanding how these technologies will fit into their environments. 

What was most relevant to me was not the AI applications themselves, but the foundational work required to support them. Cisco repeatedly emphasized the importance of modern network architectures, increased telemetry, operational visibility, automation, security, and lifecycle management. These investments provide immediate value to today’s enterprise networks while also preparing organizations for future AI initiatives. 

My takeaway is that organizations do not need to deploy AI agents tomorrow to benefit from becoming “AI-ready.” The same improvements that support future AI workloads—better visibility, automation, resiliency, and operational efficiency—also improve the performance and manageability of traditional enterprise networks today. 

The Human takeaway 

An Opportunity to Be Inspired 

One of my favorite sessions at Cisco Live 2026 was Talking with Giants: A Conversation with Some of the Key Contributors to the Development of Cisco and the Internet, hosted by Cisco legends Peter Jones and Dave Zacks. The discussion featured Cisco Fellow David McGrew and Distinguished Engineer Aaron Woland, whose work has helped shape technologies that many of us use every day. 

As network engineers, we often focus on technologies, architectures, and operational challenges, but this session was a reminder that many of the systems we rely on today exist because individuals dedicated years of their careers to solving very specific problems exceptionally well. 

I have always understood the value of being a generalist. My role requires me to work across routing, switching, security, wireless, cloud, and numerous other technologies. That breadth of knowledge is important and allows me to help customers solve complex business problems. However, sessions like this remind me how much impact can be made by those who choose to go deep into a particular discipline. 

Listening to David McGrew discuss his work in modern cryptography and Aaron Woland describe his contributions to identity and security architectures was inspiring. These are individuals who devoted themselves to a specialized area of technology and, in doing so, helped influence how the Internet and enterprise networks operate today. 

My takeaway was a renewed appreciation for both paths within our profession. Generalists bring technologies together to create solutions, while specialists push the boundaries of what those technologies can become. The industry needs both, and it was motivating to hear directly from people whose expertise has had such a lasting impact on the way the world communicates and secures information. 

An Opportunity to Inspire 

Another memorable experience from Cisco Live happened completely outside of a technical session. 

While riding the elevator at my hotel, I met a young woman on her way to the testing center to take her CCNA exam. As we talked, she asked about my background and how long I had been working in networking. When I told her I had been in the industry for 26 years, she laughed and pointed out that 26 years was how old she was. 

As our conversation continued, she began asking questions about my career, the projects I had worked on, and the biggest challenges I had faced along the way. My answer was simple: in many ways, the early years of networking were a daily “baptism by fire.” 

When I entered the industry, formal networking education was not nearly as accessible as it is today. Many of us learned through trial and error. Online training was limited, Google did not exist, AI assistants were unimaginable, and access to expert guidance was often difficult to find. In many cases, we were asked to solve problems before we fully understood how the technology worked. The expectation was simply to figure it out. 

She shared that there are times when she wonders whether she should leave the industry altogether and pursue something else. I told her not to give up. Networking can be challenging, frustrating, and humbling, but it is also one of the most rewarding professions I can imagine. I explained that one of the best feelings in this field is the moment when you realize people are coming to you for answers, guidance, and expertise. Becoming the person others trust does not happen overnight, but it does happen through persistence, experience, and a willingness to keep learning. 

At the end of our conversation, she thanked me and told me she felt re-energized and more confident about continuing her journey. As much as I appreciated hearing that, it also left an impression on me. 

One of the themes of Cisco Live for me was the people. Earlier in the week, I had the opportunity to listen to industry pioneers whose work helped shape modern networking and security. Later in the week, I found myself encouraging someone who is just beginning her own career. It reminded me that every experienced engineer was once the person asking questions, and every new engineer has the potential to become the expert others look up to in the future. 

My takeaway is that knowledge sharing remains one of the most important responsibilities we have as professionals. Technology changes constantly, but investing in people and helping others grow is one of the few contributions that continues to have an impact long after the conference is over. 

An opportunity to connect 

Last but Not Least: The People 

Perhaps my most important takeaway from Cisco Live 2026 had nothing to do with technology at all. 

Throughout the week, I had the opportunity to meet countless people who, prior to the conference, were complete strangers. Engineers, architects, consultants, managers, and technology leaders from different organizations and different parts of the country all brought unique experiences and perspectives. Some followed traditional career paths, while others arrived in networking through unexpected routes. What we all shared was a common passion for technology and a willingness to learn from one another. 

Many of the most valuable conversations happened outside of the scheduled sessions. Whether standing in line, sharing a table at lunch, attending a social event, or simply walking between venues, there were countless opportunities to exchange ideas, discuss challenges, and learn from the experiences of others. I left the conference with new professional contacts, new perspectives, and several relationships that I expect will continue long after the event itself. 

The conference also provided something I rarely experience as a fully remote engineer: the opportunity to spend time with customers in person. 

Much of our interaction with customers takes place through email, conference calls, project meetings, and support engagements. While those interactions are important, they often focus exclusively on the technical work in front of us. Cisco Live created opportunities to spend time together in a more relaxed setting where the conversations extended beyond networks, projects, and troubleshooting. 

I had the chance to learn more about the people behind the organizations we support. We talked about our families, hobbies, interests, career journeys, and the experiences that have shaped us both professionally and personally. Those conversations served as a reminder that while technology may be what initially brings us together, relationships are what ultimately sustain successful partnerships. 

My takeaway is that conferences like Cisco Live are about much more than learning new technologies. They provide opportunities to build relationships, strengthen existing connections, and develop a deeper appreciation for the people who make this industry what it is. The technical knowledge gained during the week is valuable, but the relationships formed and strengthened may ultimately have the longest-lasting impact.
