I just returned from Cisco’s Press and Analyst Conference at Cisco Live 2024 in Las Vegas, and it was quite the spectacle. The event was a grand showcase of Cisco’s attempts to reinvent itself amidst a saturated market. While there were some genuinely impressive innovations, it was hard not to feel a bit skeptical about some of the grandiose claims. Here are my key takeaways, organized into three major themes: AI Integration, Security Innovations, and The Future of Observability.

AI Integration: A Strategic Embrace

Cisco made it clear at Cisco Live 2024 that AI is central to its future. The event was filled with AI-focused sessions, panels, and keynotes, all highlighting how AI will drive the next wave of innovation at Cisco. In fact, the term “AI” was used over 300 times across 11 presentations, or on average about 27 times per 45-minute presentation. There was no doubt that Cisco wanted to impress the importance of AI, but was it really necessary to use it so often?

Chuck Robbins, Cisco’s CEO, emphasized that while Cisco remains a networking company at its core, embracing AI is essential for staying at the forefront of technology. One of the standout announcements was the AI-powered HyperFabric, developed in collaboration with NVIDIA. This new hardware is designed to support AI clusters, ensuring that Cisco remains a critical player in the infrastructure needed for AI workloads. The practical applications of AI in automating network management and optimizing performance are genuinely beneficial, promising to reduce complexity and improve outcomes.

However, it’s important to temper expectations. While AI holds great promise, the real test will be its implementation and whether it can deliver consistent, tangible improvements. Cisco’s AI strategy is ambitious, but it’s a necessary step to ensure they stay competitive in a rapidly evolving market.

Security Innovations: Promising but Future-Focused

Security was another primary focus at Cisco Live, taking second billing to AI. Cisco is committed to enhancing its security offerings, though many innovations were announcements for future products expected over the next six months.

One of the significant security announcements was related to the upcoming Hypershield, set to launch in August. This initiative, now expanded with AMD DPU integration, aims to provide advanced AI-driven micro-segmentation and threat detection for distributed workloads. Additionally, a new Cisco low-end firewall (1200) is expected in October, reinforcing Cisco’s dedication to the firewall market, where it once was the dominant market share leader but now stands far behind Palo Alto Networks.

A significant part of Cisco’s security strategy involves integrating Splunk, which was acquired earlier this year. Splunk’s capabilities in providing visibility into the internet and cloud are crucial for understanding how external factors impact network performance. While Splunk is still finding its home within Cisco, the integration process is underway and will be pivotal for future security innovations.

Cisco’s security announcements also included the new Cisco Security Cloud Control, the unified management for Cisco Security Cloud, its AI-driven, cross-domain security platform, and partnerships with Microsoft and Google. These partnerships are noteworthy, demonstrating Cisco’s strategy of collaboration to enhance its security offerings without having to build out missing capabilities themselves. However, the true impact of these innovations will be seen once the products are fully rolled out and integrated.

The Future of Observability: Integrating Splunk

Observability and digital experience management were also prominent themes at Cisco Live. These areas are critical as they represent the evolution of traditional network management into more holistic, software-centric solutions. Cisco is positioning itself as a leader in this space, recognizing that as networks become more complex, the need for comprehensive observability tools becomes paramount.

A significant part of this strategy is the integration of Splunk and cross-pollination with standing Cisco products, such as Thousand Eyes. At Cisco Live, integrating Splunk with other Cisco products was a significant highlight, showcasing how observability can lead to better decision-making and improved operational efficiency. However, Splunk feels somewhat separated from the Cisco mothership. Given that the acquisition closed only a couple of months ago, this is understandable. The integration process will take time, and it will be interesting to see how Cisco fully incorporates Splunk’s capabilities into its broader portfolio.

A Networking Giant’s Evolution

Cisco, the blue-blood networking company, had a surprisingly limited number of CEO-caliber network infrastructure announcements. Other than the HyperFabric, there were no major hardware or networking revelations directly from Chuck Robbins or his staff. On the one hand, it’s refreshing to see Cisco focus on innovative technologies beyond the traditional “speeds and feeds.” On the other hand, isn’t that precisely what made Cisco the powerhouse it is today? The lack of significant networking announcements might leave some long-time Cisco followers questioning if the company is straying too far from its routing and switching roots.

Final Thoughts: A Bold Step into the Future

Cisco Live 2024 showcased a company making bold moves to stay relevant and competitive. The emphasis on AI, the continued focus on security, and the integration of observability tools like Splunk are all part of Cisco’s strategy to expand its market reach. While there are valid reasons to be cautiously optimistic, the real challenge will be turning these ambitious plans into concrete results.

The AI initiatives, while promising, need to prove their value in real-world applications. Security improvements, though many are future-focused, show a commitment to staying ahead of threats. Observability, particularly with the integration of Splunk, represents a significant step forward, though it will require time to realize its full potential.

Cisco Live 2024 left me with a sense of cautious optimism. The company is clearly making strategic moves to adapt and innovate. Whether these efforts will pay off remains to be seen, but one thing is sure: Cisco is not standing still. They are actively shaping their future, and it will be fascinating to see how these initiatives unfold in the coming year and beyond.

A correction was made on June 14, 2024: An earlier version of this blog incorrectly referred to Cisco Security Cloud Control as ”an AI-driven platform for unified security management.” Cisco Security Cloud Control is the unified management interface for Cisco Security Cloud, which is Cisco’s unified, AI-driven, cross-domain security platform.


Like many in the security world, I, too, made the pilgrimage to Moscone Center last week to attend the RSA Conference 2024. The conference was a melting pot of ideas, innovations, and insights, with cybersecurity professionals from around the globe converging to discuss the industry’s future. Among the myriad announcements and presentations, three key themes emerged: AI-Powered securityUnified Security Architectures, and Zero Trust Adoption.

  1. AI-Powered Security: The New Frontier

Artificial Intelligence (AI) has been a buzzword in the tech industry for years, but its application in cybersecurity has now moved from hype to reality. AI is being used to automate threat detection and response, reducing the time it takes to identify and mitigate potential attacks. It’s also being used to automatically analyze anomalies and correlations to prevent threats. This shift towards AI-powered security signifies a new era in cybersecurity, where intelligent, automated systems are replacing manual processes. However, as AI evolves rapidly, so does the sophistication of AI-powered threats, necessitating continuous innovation and adaptation in our defensive strategies.

  1. Unified Security Platforms: Simplifying Complexity

The second theme that stood out was the move towards unified security platforms. Managing multiple, disparate security solutions can be daunting with the increasing complexity of today’s digital environments. There’s a trend toward offering comprehensive, integrated security platforms to address this issue. These unified platforms aim to provide end-to-end security, covering everything from cloud security to endpoint protection and everything in between. By consolidating various security functions into a single platform, these solutions aim to simplify security management and enhance visibility and control across the entire digital landscape. Industry momentum has gone as far as turning the word “platform” into a verb (“platformization”)!

While it would be ideal to have a single platform to rule them all, it’s unlikely an enterprise would or could put all its security eggs into a single vendor’s basket, whether due to political (“I don’t want to be beholden to a single vendor”), economic (“How can I get the best price if standardized on single vendor?”), or technological (“I need best-of-breed and no single vendor is best-of-breed across all security fronts”) reasons. Fortunately, vendors may be talking platforms, but they are also creating connective tissue between disparate systems and other vendors’ products, which ultimately benefits everyone.

  1. Zero-Trust Adoption: A Paradigm Shift in Security

The third theme that emerged was the widespread adoption of Zero-Trust security models. In a Zero-Trust model, every user, device, application, and piece of data is treated as potentially compromised and verified before being granted access. This shift from the traditional ‘trust but verify’ approach to a ‘never trust, always verify’ model signifies a paradigm shift in security that has been around for numerous years but is finally catching fire.

However, it’s important to note that Zero-Trust isn’t one product or solution. It’s a comprehensive approach to security that can be applied across users, devices, applications, data, and network traffic. While in an ideal world, a single solution from a single vendor would span the entire spectrum, the reality is far more complex. There will always be multiple solutions and vendors, each with strengths and weaknesses. The challenge lies in integrating these diverse solutions into a cohesive security strategy that aligns with the principles of Zero Trust. Despite these challenges, the widespread adoption of Zero Trust is a positive step forward, helping organizations stay one step ahead of attackers and ensuring they are prepared for future challenges.


The RSA Conference 2024 provided a glimpse into the future of cybersecurity, highlighting the industry’s shift towards AI-powered security, unified architectures, and Zero-Trust models.

Turbulent is the best word to describe the worldwide Enterprise Network equipment market over the past few years. Enterprise Network manufacturer revenues hit a high of $72 B in 2023. However, by the end of 2023, signs of an impending market shift appeared.

To predict what will happen next, we look back over the past ten years to identify the overarching trends that are influencing this market, which is made up of manufacturer revenues from hardware and software purchased by enterprises for network connectivity and security purposes, divided into the five sub-markets shown in the figure below.

Over the five-year period from 2014 and 2019, the worldwide Enterprise Network market experienced a Compound Annual Growth Rate (CAGR) of 7%. Manufacturers such as Cisco, Huawei, HPE, Arista, Palo Alto Networks and Fortinet have managed to grow revenues–even as challengers, such as Juniper and Zscaler, gained market share.

Tracking of Secure Service Edge (SSE) and Web Application Firewalls (WAF) markets began in 2019, contributing to the significant growth of the Network Security market. While annual growth of Switch and WLAN slowed in 2019, the fundamentals of the Network Security (firewall, SSE, SWG, WAF, and ADC) and Branch Routing markets (SD-WAN and access routing) remained robust, pushing overall network equipment spending up to $48 B.


The Market Trajectory is Altered

Then, in 2020, the pandemic hit. Workers vacated their offices and network projects ground to a halt. The following year, with IT leaders besieged with demands for networking to support remote work, companies tried to get digital transformation initiatives back on track – just as vendors began to experience supply shortages. Equipment hardware lead times became long – but worst of all, unpredictable. They could be close to normal, or they could be twenty times longer than normal, depending on the type of equipment and the day that the orders were placed. Manufacturers began to accumulate large backlogs of orders. Equipment prices began to rise, keeping industry revenues growing despite the longer wait times for enterprises.

Near the end of 2022 and into early 2023, the tide began to change. As supply began to flow to the equipment vendors, they began to ship more networking equipment. Then, backlogs spiraled downward, and the market was flooded. Manufacturer revenues ballooned.

Since the end of 2022, Dell’Oro Group has been predicting a digestion period, or a pause in spending on some segments of the Enterprise Network market. This slowdown first appeared in Wireless LAN revenues in 3Q23, as the market contracted Y/Y for the first time since 2Q20. This was followed by Y/Y contractions in Branch Routing and Campus Switching in 4Q23. These contractions are expected to continue throughout most of 2024. During the period of supply constraints, many enterprises adjusted their ordering behavior, placing orders in 2022 for equipment they required in 2024. In addition, in times of scarcity, distribution companies ordered more equipment than they needed. Now that the deliveries have been made, working through the excess inventory will take time.


An Uneven Revenue Recovery

Supply constraints and rapid backorder fulfillment have created the roller coaster trajectory of the worldwide Enterprise Networking market. However, if we look more closely, we see that the peaks and troughs of each sub-market are not aligned.

Growth of Enterprise Data Center switching revenue, in particular, did not reach the same heights in 2023 as the other enterprise networking markets. However, revenue growth remained positive throughout the year, driven by large enterprises. The supply constraints for switches were resolved later than those for WLAN, and manufacturer backlogs have remained elevated for longer, leading to a continued stretch of Y/Y growth in revenues. Dell’Oro group is also projecting a digestion period for enterprise switching – although it is expected to be offset from that of WLAN and Branch Routing.

In contrast, the Network Security market stands out as the only market that has grown at least 5% every year for the last ten years. This consistent growth reflects the critical role of network security in enterprise strategies to mitigate cyber threats. Although the Y/Y expansion has been slowed somewhat by the enterprise digestion phenomenon, market expansion is anticipated again in 2024, whereas Dell’Oro Group expects all other segments to contract.


A Shift in IT Priorities

The continued importance of IT security to enterprises will cause a share shift in Enterprise Network revenues over the longer term. In 2023, spending on Network Security more than doubled from just five years ago. By 2028 Dell’Oro Group expects Network Security to account for an even larger portion of equipment sales. On the other hand, the switch market is more mature. Following the increasing penetration of Work From Home and Hybrid Work models, Enterprises’ adoption of Wi-Fi First strategies has grown, dampening the expansion of Campus Switch revenues in favor of WLAN. In addition, enterprises’ shift to cloud computing has slowed the growth of Enterprise Data Center Switch spending.

Looking forward to the anticipated CAGR of the worldwide Enterprise Network market, Dell’Oro Group has a word of warning for industry observers. Using the elevated 2023 revenues as a baseline is sure to make future CAGR calculations look anemic. Taking an average over 2021 to 2023, smoothing out the supply release tsunami, allows us to predict that cumulative growth rates should return to pre-pandemic levels over the next five years.


About three years ago, Zscaler’s CEO Jay Chaudhry expressed a viewpoint in an SDxCentral article that distanced the company from the SD-WAN market. Chaudhry stated, “Network security is not really very meaningful. We decouple network access and application access with zero trust. We don’t put people on the network, we connect a person to a particular application or service. If you believe that network and security should be decoupled, there’s no reason for Zscaler to get into the SD-WAN space.” This stance highlighted a philosophy focused on securing direct application connections rather than managing the broader network layer.

Fast forward to last week’s Zscaler Zero Trust (ZT) SD-WAN announcement. Zscaler unveiled a strategic pivot that places them squarely into the SD-WAN space, indicating a significant expansion of their focus towards networking. By introducing new hardware appliances, the Z connector series, Zscaler targets small to medium-sized branches, aiming to blend zero trust security with SD-WAN capabilities. This move positions Zscaler as a competitor against existing SD-WAN behemoths like Cisco, departing from Chaudhry’s earlier assertions.

I had the opportunity to sit down with Zscaler this week for a briefing on the new Z connector appliance family encompassing three models: the ZT 400, ZT600, and ZT 800. The hardware appliances range in performance from 200Mbps to 1Gbps, which Zscaler stated was sufficient for small to medium branches. Zscaler admitted the need for higher throughput hardware and is actively investigating. Until faster hardware arrives, customers must rely on the VM-based software appliance (Zscaler Branch Connector) that can scale horizontally with 3rd-party load balancers.

A critical application of Zscaler’s strategy is enhancing IoT environments, with the appliances featuring IoT device discovery, yet, notably, they do not include Wi-Fi capabilities. Distinctively, Zscaler adopts a subscription-based model for its Z connector appliances, marking a departure from most of the industry’s standard practice of selling hardware solely through a capital expenditure (Capex) model. Details on the pricing remain confidential, with an announcement scheduled for this month (February) alongside the release of the Z connector software.

Zscaler’s SD-WAN strategy presents a streamlined, cloud-based alternative to complex traditional networking frameworks, emphasizing ease of management. The conversation underscored Zscaler’s potential to enhance or supplant current SD-WAN infrastructures. Yet, Zscaler recognizes its significant challenges in evolving into a hardware-centric enterprise. These challenges span the spectrum from regulatory compliance and establishing efficient distribution networks to ensuring next-day hardware replacement capabilities and bolstering support services. Additionally, Zscaler is focused on refining its SD-WAN solutions to enhance competitiveness and expand its offerings to support larger branch networks, necessitating integration with campus and Network Access Control (NAC) systems (in the vein of “Universal ZTNA”).

Adopting Zscaler Z-connector appliances positions Zscaler as a central network provider, managing secure application access via its Zero Trust Exchange and linking an enterprise’s operational integrity to its performance. This shift towards consuming a secure network as a service, akin to how cloud services for servers and storage are utilized, marks a significant change in enterprise networking that may feel foreign to some. Networking goes from hardware with blinking lights to an ephemeral service from the cloud. Despite this, it’s part of an industry-wide transformation, with other progressive vendors like Aryaka, Cato Networks, Cloudflare, and Versa Networks offering some or all their network services in a similar fashion.

This trend toward network as a service, the SASE framework, and multi-cloud networking are key pillars of my Distributed Cloud Network concept, which I discussed in my op-ed on SDxCentral. Collectively, these elements represent the future of enterprise networking, integrating new technology and consumption models into the broader, evolving landscape of enterprise IT strategies.

Zscaler’s evolution from sidestepping SD-WAN by exclusively relying on integrations with third-party SD-WAN vendors to now offering SD-WAN capabilities natively underscores the company’s adaptability and strategic growth. This shift highlights Zscaler’s responsiveness to changing market dynamics and marks a significant new chapter in its journey as a single-vendor SASE provider.

My SWOT analysis follows:


  • Market-leading SSE with a strong security focus with zero trust architecture.
  • Simplified cloud management and deployment.
  • Targeted solutions for small to medium-sized branches.
  • Adoption of a modern subscription-based business model.


  • New entrant in the hardware-focused networking market.
  • Limited hardware portfolio breadth.
  • Pricing strategy not clearly defined.
  • Convincing established customers to switch from traditional vendors and approaches may pose challenges.
  • ZIA and ZPA are built on separate technology stacks and operate as distinct networks, unlike some newer SASE vendors that utilize a single network with a common technology stack. Having separate technology stacks/networks increases the risk of subpar networking performance and reliability.


  • Rising demand for integrated security and networking solutions.
  • Shift towards service-oriented and cloud-based network management.
  • Opportunity to capture a niche market looking for simplified SD-WAN solutions.


  • Competition from better-established SD-WAN vendors like Cisco, Fortinet, and Palo Alto Networks.
  • Resistance from customers loyal to traditional networking methods that rely on more of the security and networking smarts embedded in each SD-WAN device.
  • Need for continuous innovation in a rapidly changing SD-WAN and security landscape.
  • Newer SASE vendors offering a unified technology stack across functions may appeal to customers seeking streamlined solutions, posing a competitive threat to Zscaler’s dual-product approach.

In this annual forecast blog covering our network security and SASE/SD-WAN services, we explore a pressing question for 2024: Will 2024 be the year traditional firewalls and branch access routing die in favor of SASE? As we embark on a new year, it’s crucial to examine how these longstanding network security and connectivity pillars are expected to respond to the rapid advancements and growing adoption of SASE (which we see as the combination of SSE and SD-WAN). Let’s dissect how these adjacent markets are expected to behave in 2024 and influence each other to reveal a complex narrative of give and take.

Firewalls Won’t Die in 2024 but Will Continue to Take Some Body Blows

In 2024, the overall firewall market is set to experience a modest, low-single-digit growth, mirroring its performance in 2023. This steady yet subdued growth trajectory reflects the market’s resilience amidst evolving challenges and the shifting landscape of network security. For example, after weathering a significant 16% drop in 2023, the high-end firewall market is expected to rebound slightly with a single-digit increase in revenue. This recovery, although modest, signals a stabilizing trend under the influence of broader economic conditions and a restart of purchasing by service provider customers.

Conversely, the midrange firewall market anticipates a single-digit decline in 2024 after growing solidly in 2023. This downturn highlights a shift in the fortunes of a wider swath of the enterprise market, which is expected to return to earth after robust growth in the past couple of years. The low-end firewall segment, in contrast, is forecasted to see a marginal 1% growth. This limited increase points to the segment’s challenge in adapting to the growing preference for cloud-based alternatives and the evolving requirements of hybrid work environments.

On a brighter note, the virtual firewall market is poised for a significant surge, expecting a nearly 40% increase in revenue in 2024. With impressive growth, it will represent nearly 15% of the overall firewall market, underscoring the sector’s growing importance in a cloud-centric world and its adaptability to protect distributed, dynamic environments.

Despite the varied performance across these segments, the overall firewall market’s persistence in achieving low single-digit growth in 2024 suggests a continued relevance and necessity for firewalls in network security, albeit in an evolving role and form.

Access Routing Will Become a Shell of its Former Self in 2024 if Cisco Gets Their Way in the SD-WAN Market

Access routing, a mainstay in enterprise networks, is undergoing a dramatic transformation, largely influenced by Cisco’s strategic push towards SD-WAN. With the sunsetting of its successful ISR 4k access routers and the introduction of the Catalyst 8000 series, which are optimized for SD-WAN, Cisco is steering the market towards SD-WAN. This shift marks a significant pivot from traditional access routers to more agile, software-defined networking solutions.

The impact is stark: access router revenue is expected to drop by over 30% in 2024 to $1.4 billion. This seismic shift underscores the industry’s rapid adaptation to the changing needs of enterprise networks, favoring flexibility and cloud integration over traditional hardware-centric models. As SD-WAN gains prominence, it’s clear that access routing, as we know it, is on the brink of a fundamental change.

SASE Will Buck Market Uncertainty and Crack $10 B for the First Time

In 2024, the SASE market is expected to continue its upward trajectory, bucking broader market uncertainties and achieving a record-breaking milestone of $10 billion. This growth underscores the rising importance of SASE as a cornerstone in modern enterprise networking and security strategies. The surge in SASE’s popularity is driven by its ability to seamlessly combine SD-WAN networking with SSE security into an integrated service. This integration increasingly appeals to enterprises seeking efficient, streamlined, and secure network infrastructures, especially in an era of distributed workforces and cloud-centric IT models.

2024 will stand as a landmark year for SASE, not just in terms of technological adoption but also as a strategic response to the evolving needs of modern network environments. Reaching the $10 billion mark is a testament to its growing significance and the industry’s shift towards integrated, agile, and cloud-centric network solutions.

As we analyze the trajectories of firewalls, access routing, and SASE in 2024, it’s clear that we’re witnessing a period of significant transition in the enterprise network and security landscape. Traditional firewalls and access routing are being redefined and challenged by the rising tide of SASE, which offers a more integrated, flexible, and cloud-centric approach.

This evolution is not just about technological change; it reflects a deeper shift in how enterprises view and manage their networks in an increasingly cloud-dominated, hybrid work environment. While traditional solutions will not vanish overnight, their role and relevance are being reshaped in the face of these emerging paradigms.
