The network stopped having edges
Traditional WAN routes every branch back through a central data centre over expensive, inflexible MPLS links, adding latency to cloud and SaaS traffic that was never designed to make that detour.
Traditional VPN access compounds the problem. Once a user or a device connects, they typically land inside the broader network, not just the one application they needed. A single compromised laptop or stolen credential can move sideways from there, often for weeks before anyone notices.
Hybrid work, distributed branches and workloads spread across cloud, on-premises and containers mean there is no single perimeter left to defend. The network has to be secured at the connection and the workload, not at a gate that no longer exists.
What good looks like, before the products
Modern networking and access architecture, done properly, changes four things at once: performance, cost, security and flexibility.
Improved performance
Traffic is directed over the best available path in real time, so critical applications get priority instead of competing with everything else.
Lower cost
Broadband and cellular connections replace or supplement expensive MPLS, without giving up reliability.
Stronger security
Encryption, segmentation and Zero Trust access replace implicit trust in anyone who's made it onto the network.
Real flexibility
New sites, remote workers and cloud workloads are added without a re-architecture every time.
SASE and SD-WAN, converged into one platform
Rather than a separate box for routing, another for security and a third for remote access, SASE converges all three into a single cloud-delivered architecture with one policy engine behind it.
Next Gen SASE Branch
Modernises branch infrastructure by converging SD-WAN and security into one cloud-delivered platform, replacing the stack of separate boxes most branches still run.
Zero Trust Network Access
Replaces legacy VPNs with identity-based access to specific applications, not the whole network behind them.
Endpoint SD-WAN
Extends the same policy and performance to individual remote users and devices, not just branch offices with dedicated hardware.
Micro Branch
A lightweight SASE deployment for small sites with limited infrastructure, without cutting corners on security.
Wireless WAN
Ruggedised, cellular-first connectivity for vehicles, remote sites and anywhere a fixed line isn't practical.
Multi-Cloud Networking
One console to manage routing and policy across AWS, Azure and Google Cloud, instead of a separate setup for each.
Zero Trust, enforced at every workload
The problem it solvesA flat network lets one compromised device reach everything else on it. Traditional firewalls are written per environment, one rule set for on-premises, another for each cloud account, so policy never travels with the workload and rarely keeps up with how fast environments change.
How it worksIllumio builds policy from a workload's identity, not its IP address. Tag a workload once, and the rule follows it wherever it runs, on-premises, in any cloud, or on an endpoint, and every new instance inherits the right policy automatically.
One policy engine for every workload
Real-time visibility
Every connection across your cloud workloads, on-premises servers, containers and endpoints, mapped in real time. No manual mapping, and policy is generated from what it sees.
Every environment covered
Policy built from workload identity, not IP address. Tag a workload once and the rule follows it to AWS, Azure, a bare-metal rack or a container.
Zero Trust, easily enforced
No implicit trust between workloads, not just at the perimeter. Model a policy in draft view and see exactly what it would block before you turn it on.
"Most teams don't know how much east-west traffic crosses their environment until they map it. Illumio builds that map in minutes."
