Work no longer changes one piece at a time. Applications, access, security, and now AI are all shifting at once, and lean IT teams are expected to keep up with every one of them.
For a long time, the old playbook worked: applications lived in the data center, most users worked from the office, and security controls were anchored at headquarters. That model is gone. Users connect from everywhere, applications have moved to SaaS and cloud, branch offices need reliable direct access, and employees are experimenting with new AI tools faster than anyone can keep up with them.
For a lean team, the answer cannot be another appliance, another console, and another policy stack every time the business changes.
That pressure is pushing the market toward convergence. Gartner predicts that by 2026, 60% of new SD-WAN purchases will be part of a single-vendor SASE offering, up from 15% in 2022.
The direction is clear. Organizations want networking, security, and AI delivered as a single architecture rather than a stack of disconnected tools.
The good news is that you do not have to get there in one move. Here’s how lean IT teams scale into a full SASE platform, one use case at a time.
Start where the pain is
Every organization feels the strain differently. For some, it is network cost and complexity: aging MPLS contracts, branch sprawl, and inconsistent application performance.
For others, it’s security and vendor sprawl, with too many tools and too much manual work to keep policies aligned.
Some teams are focused on remote access and user experience. A growing number are trying to let employees use AI safely without losing visibility into data and activity.
The common thread is complexity. SASE addresses this by consolidating these priorities into a single architecture rather than treating each as its own project. You do not have to start with AI security, and you do not have to start with the network. You choose the problem worth solving first, and whatever you start with becomes an entry point into the same platform, not a dead end you rebuild later.
Four entry points into one platform
A true SASE platform converges SD-WAN, security service edge (SSE), universal Zero Trust Network Access (ZTNA), and AI security into a single cloud-delivered service. Any one of them can be your first step.
The platform behind this approach already supports more than 4,000 enterprises, over 60,000 connected sites and cloud locations, and more than 2 million remote users, so the foundation is proven before you add your first use case.
Give every user and device one access policy
Remote access is where many teams begin. The challenge is that access has broadened well past employees on managed laptops. Contractors, third parties, unmanaged devices, branch sites, and AI agents all need to reach applications and data, and every new access method used to mean another policy model and more policy sprawl.
Universal ZTNA replaces that with one policy for every user, device, and location. Access decisions are continuous and risk-based, so the same rules apply whether someone connects from headquarters or a hotel room.
You can check a device for the company security certificate before it touches a sensitive application, and if a user appears to travel from Chicago to Mexico in ten minutes, the platform treats that impossible travel as a signal and lowers what it will trust. The payoff is simpler access, stronger control, and far less operational overhead.

Consolidate your security stack
Traditional SSE fragments quickly: different vendors, consoles, policies, and separate data silos that hide attack paths. Delivering SSE through a single cloud-native platform reduces it to a single policy engine and a single data lake, with shared context across the entire security stack. Because everything runs from the same place, protection extends everywhere at once instead of tool by tool.
Running on a single platform also enables autonomous, agentic protection at cloud scale. Instead of waiting on appliance updates, patch cycles, or rollout projects, defenses evolve at machine speed and keep pace with the same frontier AI tools attackers are starting to use.
Run SD-WAN as a cloud service, not an appliance project
Traditional SD-WAN can turn into an endless branch-appliance rollout: deploy hardware, troubleshoot last-mile issues, and try to force predictable performance over unpredictable networks. Run as a cloud service, sites, users, and applications connect into a global private backbone of more than 100 points of presence worldwide, backed by a 99.999% availability SLA. The result is predictable performance, intelligent path selection, and visibility across the whole environment without the truck rolls.
This is the approach that pays off when the network becomes strategically important: mergers and acquisitions, distributed retail and branch networks, MPLS replacement, cloud transformation, and reaching hard-to-serve locations. In those situations, architecture decides whether a project takes days, months, or years.
Secure the AI your business is already using
AI security covers three jobs at once: protecting the AI your employees use, the AI your developers build into applications, and the AI agents your business runs. Point products tend to solve one of these in isolation, which means AI activity gets viewed outside the context of everything else on the network.
Built into the platform, AI security works differently. You can see AI interactions alongside the user, device, application, data, and the network traffic behind them. When someone pastes an API key or sensitive financial data into a public tool, the platform can redact it or block it before it ever reaches the model. That is visibility you can act on, not a report you read after the fact.

Why convergence beats a stack of point products
When networking, security, and AI run from the same cloud-native platform, the operating model changes. Policies update globally in seconds, threat intelligence improves everywhere at once, and events correlate into a single story instead of sitting in separate systems waiting for someone to connect the dots. That speed is how the platform reached a world-record 45-minute time to protection with automated CVE mitigation.
The business case follows the architecture. A Forrester Total Economic Impact study found organizations moving from fragmented point products to a unified platform achieved a 235% return on investment, payback in under six months, more than $2 million in labor savings, and over $10 million in licensing and telecom savings. The recognition tracks too: the platform is named a Leader in SASE by Gartner and a Leader and Outperformer in SASE and SSE by GigaOM.
Numbers aside, shared context is the entire point. A platform sees AI activity in the context of users, devices, and data. It ties a remote-access decision to the risk score behind it. Point products cannot do that, because the data never lives in one place.

What a single console actually shows you
The benefit of convergence stops being abstract the first time your team opens one console and sees the whole environment at once: remote users, branch sites, and cloud locations in the same view. With that visibility, you can finally see which applications people actually use, who uses them most, and when, then decide what to prioritize and what to shut off.
Experience monitoring is where it earns its keep. When someone reports that an application is slow, the platform shows you where the problem really sits:
- The device, when memory or CPU is maxed out.
- The local Wi-Fi or LAN, when a remote user has drifted too far from their access point.
- The last mile, when the circuit itself is degraded.
- The nearest point of presence, in the rare case the platform is the cause.
- The application, when the slowdown is upstream of everything else.
Instead of “the network is down,” your team gets the exact layer to fix. The same console builds security events into stories rather than isolated alerts, correlating what happened so you can see how an intruder got in, where they moved, and what they touched, all in one place rather than stitched together across three systems after the fact.
For AI, that visibility reaches down to the session. You can see which AI tools are in use and by whom, open an individual session, and review the actual prompts and responses. If a user submits sensitive data, you can redact it. If a request is out of bounds, you can block it.
The same data controls work more broadly, so you can let a team download from a cloud storage app without allowing uploads, or permit the company tenant while blocking personal accounts.
Scale on your timeline, not all at once
You do not have to put all your eggs in one basket to get the benefit. If you are already running an SD-WAN solution you like, you can adopt universal ZTNA on top of it and start gaining visibility and control right away.
That is exactly how Momentum runs it internally. Cato’s universal ZTNA secures the corporate network, layered on top of the existing SD-WAN. If AI is the fire today, start there instead. The architecture is ready whenever you are, because each entry point feeds the same platform rather than a separate one.
The questions to ask hold true regardless of vendor:
- Does it simplify operations?
- Can it support the next phase of your business?
- Can it adapt faster than the threat landscape evolves?
Architecture is what determines how quickly your organization can respond to both opportunity and risk.
Momentum brings the SASE platform from Cato Networks together with deep expertise across cloud, voice, network, and security. One provider to design and manage it, one bill to simplify procurement, and one team that knows your environment from network design through day-to-day support. You start with the use case that matters most and grow into the rest on your schedule.
