Your perimeter is secure.
What happens after trust is granted?
Authentication is in place. Multi-factor is on. Certificates are current. But once a user or device is inside your network, how much control do you actually have? In most environments, access paths multiply without policy. Devices sit unclassified. Configurations drift. Lateral movement — the technique that turns one compromised endpoint into a full breach — goes unchecked.
That gap is where incidents start. And it's what Segmentation and Fabric solves.
Why Traditional
Segmentation Breaks Down
Segmentation has been a core networking concept for decades. The environments it needs to protect have changed completely.
SaaS adoption, hybrid workloads, federated identity, and distributed access mean the network edge no longer exists as a defined boundary. Trust is established quickly. Enforcement often is not. The result is exposure that is hard to see and harder to contain.
When segmentation fails, the blast radius of any incident grows. Response takes longer. Recovery costs more. And control (the thing your team is accountable for) is harder to demonstrate.
- Macro-segmentation is in place, but micro-segmentation is inconsistent or absent across campus, branch, and data center
- Devices connect and operate without classification — no defined identity, no assigned policy
- Policy intent at design time drifts from actual enforcement within months of go-live
- Compliance audits rely on documentation that does not reflect how the network actually behaves
- Incident response is slow because lateral movement was not contained
60% of AI and enterprise SaaS applications now operate outside IT visibility. That is the environment segmentation has to work in.
Network Segmentation + Modern Fabric: control that follows the user, not the port.
Segmentation and Fabric is an identity-driven enforcement model. Policy is tied to who the user is and what the device is : not where it happens to connect. That policy is applied consistently across your environment: campus, branch, data center, and cloud.
R2 builds this on Cisco's Software-Defined Access (SDA) platform. SDA creates a centralized fabric where access intent is defined once and enforced everywhere. Configuration changes deploy consistently across sites. Unknown devices get classified. Policies don't drift because you don't maintain them device by device.
This is not a product refresh. It is an operational shift: from a network your team manages manually to one that enforces policy automatically and reports on it clearly.
"Authentication is the starting line, not the finish line. Every session inside the network needs to be classified, authorized, and enforced."
What Segmentation + Fabric delivers for your team.
Complete visibility across your environment
See every user, device, workload, and application in real time. Unmanaged assets are classified. Blind spots are addressed before they become incidents. Your team works from accurate data, not assumptions.
Identity-based access control
Policy is assigned based on who and what users and devices are. Access follows them across wired, wireless, and remote connections — and adjusts when session context changes. Location does not determine permission.
Consistent enforcement at every point
Campus. Branch. Data center. Cloud. Policy intent translates into active enforcement across all environments — not just the locations your team had time to configure individually.
Contained blast radius when incidents occur
Segmentation limits how far a compromised endpoint can move. Containment time decreases. Evidence of control is clear for auditors, insurers, and leadership. Incidents stay smaller because the access paths are not there.
Network Segmentation + Data Center Fabric
Most SDN segmentation strategies are well designed. The problem is execution.
As environments expand across campus, branch, data center, and cloud, policy intent fails to keep up with how the network actually changes. Visibility fragments. Access paths multiply. Enforcement breaks down at the places your design did not account for.
We assess your environment before we recommend anything. We design the segmentation fabric to match how your organization operates — not a reference architecture built for a different environment. We deploy with defined milestones, documented deliverables, and clear reporting throughout.
And we stay accountable after go-live. Because the fabric is only as good as how it holds up over time.
- Segmentation design that does not align to actual business requirements or compliance frameworks
- Policy drift between go-live and six months later, when the environment has changed but the rules have not
- Internal teams without the specialized expertise to manage and evolve the architecture over time
- Stakeholder misalignment that stalls execution and leaves coverage gaps
A better approach:
Find. Fix. Finish Strong.
Find
Assess your current network architecture. Identify gaps in visibility, segmentation coverage, identity classification, and policy enforcement. Surface what the environment actually looks like, not what the documentation says.
Fix
Design and implement the Cisco SDA fabric with defined segmentation policies, identity roles, and aligned SLAs. Translate policy intent into active, enforceable controls across your environment.
Finish
Validate performance, optimize segmentation effectiveness, and report on SLA adherence. Deliver documentation your team can use and auditors can review. Leave the environment stable and ready for production.
Exploit
Identify where the segmentation fabric can extend as your environment grows — new sites, new workload types, new compliance requirements. The architecture is built to scale without starting over.
Analyze
Review segmentation data, policy adherence, and incident trends on an ongoing basis. Identify where enforcement holds and where gaps are forming before they become problems.
Disseminate
Deliver runbooks, reporting, and documentation that make your environment understandable, auditable, and manageable by your internal team over the long term.
Audit Where your Segmentation Stands Today
Not sure where enforcement is holding and where it is breaking down? The Segmentation Maturity Checklist helps IT and security leaders evaluate policy coverage, identity alignment, and enforcement consistency, so your team knows what to address first.
Measurable outcomes
your team can report on.
When Segmentation and Fabric is built and maintained correctly, the network becomes a foundation instead of a liability. Your team spends less time managing configurations and more time on work that moves the business forward.
R2 measures success against these benchmarks from the start of every engagement — and reports on them throughout. Results without surprises is not a promise. It is the standard.

Get Your Software-Defined Networking Questions Answered
What is Segmentation and Fabric?
Segmentation and Fabric is an identity-driven enforcement model built on Cisco's Software-Defined Access (SDA) platform. It replaces location-based access control with policy that follows users and devices across your entire environment — campus, branch, data center, and cloud. Policy is defined once and enforced consistently, without device-by-device configuration.
How is this different from the VLANs and firewall rules we already have?
Traditional segmentation relies on static, location-based rules maintained device by device. When environments change, those rules drift out of alignment with actual access behavior. Segmentation and Fabric is identity-based. Policy follows the user or device regardless of where they connect and adjusts dynamically based on session context. It scales as your environment grows.
What is Cisco SDA and why does R2 build on it?
Cisco Software-Defined Access is the leading platform for building a modern segmentation fabric across complex, distributed environments. It centralizes policy control, automates configuration deployment, and enables identity-based enforcement across wired, wireless, and WAN environments. R2 uses SDA because it delivers the architecture outcomes our clients require — not because it is the most straightforward product to deploy.
What does a Segmentation and Fabric Assessment include?
R2's assessment covers your current network architecture, visibility gaps, segmentation coverage, identity classification, and policy enforcement. We identify what is working, where exposure exists, and what changes are needed — and deliver a documented findings report with specific, prioritized recommendations. You will have a clear path forward before any implementation begins.
How long does a Segmentation and Fabric deployment take?
Timelines vary based on environment size and complexity. R2 scopes every engagement upfront with defined phases, milestones, and deliverables so expectations are set before work begins. Our approach prioritizes structured execution over speed — reducing rework and delivering stable results.
What happens if we delay building out segmentation?
Lateral movement risk increases as environments expand without consistent enforcement. Every new application, site, or unmanaged device added to the network is a potential path that policy does not cover. The cost of an immature segmentation strategy shows up in incident response — in containment time, recovery cost, and the evidence you cannot produce for auditors or insurers.
Can R2 work with our existing network infrastructure?
Yes. R2 designs segmentation architectures that align to your current environment. We assess what exists, identify what can be retained, and phase the implementation to reduce disruption. Organizations do not need to replace everything to build an effective segmentation fabric.
How do we know the segmentation is actually working after deployment?
R2 measures and reports on segmentation effectiveness, policy adherence, and SLA performance throughout the engagement and after go-live. We define success benchmarks at the start and track against them. Your team has clear, ongoing visibility into how the environment is performing — and so does leadership.
