As a Secure Access Service Edge (SASE) provider, your service is only as strong as the network that underpins it. You promise users consistent, secure access to applications and data across geographies, but delivering on that promise becomes exponentially more challenging when your infrastructure depends on public networks, which are inherently unpredictable.

And the cost of that unpredictability can be staggering. According to Splunk and Oxford Economics, Global 2000 companies lose an average of $200 million annually to unplanned downtime, with each minute of disruption costing $9,000, or $540,000 per hour.

Even a brief lapse in your service can break service level agreements (SLAs), erode revenue, and shake the customer trust you’ve worked so hard to earn.

Upholding those critical SASE SLAs requires more than encryption and policy enforcement. It demands a high degree of control over your network, or more specifically, the ability to steer where and how traffic flows with minimal network fluctuations.

As you build and scale your SASE platform, the performance and reliability of your underlying network are non-negotiable. After all, security policies and access controls only matter if users can actually reach your edge infrastructure quickly, reliably, and securely.

Unfortunately, the decentralized, patchwork nature of the public internet was never designed for this level of predictability.

With Zenlayer as your partner, you don’t have to settle for fragmented infrastructure performance. Our 180+ Tbps private backbone, 300+ global edge nodes, and 10,000+ optimized peering relationships give your SASE service the network stability you need to meet SLAs and grow with confidence — anywhere.

 

Move beyond unpredictable routing

Many SASE platforms begin with a blended IP transit model, purchasing bandwidth from multiple upstream providers to balance reach, redundancy, and cost. While this strategy is straightforward and relatively quick to deploy, its long-term limitations become more apparent as traffic scales.

Rerouting grows less stable, troubleshooting gets more complex, and latency-sensitive applications start to suffer, making it harder and harder to meet SLA targets.

This is because traditional blended IP transit lacks end-to-end visibility and path control. Routes can shift without warning as ISPs rebalance their networks or respond to congestion, causing unexpected latency spikes. Even small variations in packet delay can disrupt encrypted tunnels, introduce inspection lag, or trigger security policy violations.

Worse, multi-tenant congestion on shared upstream paths injects jitter and packet loss into the user experience, often at the most inopportune times.

These issues are especially prominent at the edge when users connect to your service for the first time, where latency, reliability, and consistency are most visible. Even if your internal infrastructure is well-architected, inefficient ingress can sharply degrade performance, leading to a surge in support tickets and SLA penalties.

 

Take control of your network with Zenlayer IP Transit

Zenlayer’s premium IP transit is engineered from the ground up to meet the demands of performance-sensitive workloads like SASE. Our global network prioritizes stability, routing transparency, and edge proximity to help ensure your users connect quickly and smoothly, wherever they are.

Operating one of the most densely peered IP transit platforms in the world with 10,000+ optimized peering relationships, direct interconnections with top regional ISPs, and 300+ edge nodes across both established and hard-to-reach markets, traffic enters our network closer to the user and stays under intelligent control from ingress to delivery.

But transit quality isn’t just about raw performance. There’s also routing flexibility and IP ownership.

With our full Bring Your Own IP (BYOIP) support, you can advertise your own IP space across our network to maintain full ownership and continuity. This simplifies platform migrations, preserves your brand identity, and eliminates the risk of shared IP blacklisting. If any abuse reports or access issues surface, you’ll be able to resolve them directly without waiting for a response from upstream providers.

We also support Anycast, which means you can advertise the same IP prefix from multiple edge locations at once, anywhere in the world. This way, global users are automatically routed to the nearest node, guaranteeing reliable, low-latency access to a single IP address regardless of geographic location.

For your SASE platform, this greatly accelerates global service delivery and ensures real-time applications like Zero Trust Network Access (ZTNA) or Secure Access Gateways (SWGs) perform consistently for all users.

Additionally, you’ll get full Border Gateway Protocol (BGP) and AS-SET support, which lets you advertise your own prefixes, use your AS numbers, and streamline routing announcements across our network and upstream providers without complex, manual coordination.

It’s your traffic, your routing policies, and your control, backed by Zenlayer’s global infrastructure.

 

Accelerate cloud access for SASE workloads

Chances are, your SASE architecture depends on cloud-hosted components, whether it’s for policy enforcement, identity management, analytics, or delivery. Ensuring fast, reliable access to those services is just as important as optimizing the underlying network.

Our 300+ direct cloud onramps simplifies cloud access to major providers like AWS, Azure, Google Cloud, Oracle Cloud, Alibaba Cloud, and Tencent Cloud, letting you bypass public networks and route traffic through dedicated, high-speed paths for improved consistency, lower latency, and better end-to-end visibility between your edge nodes and cloud-based services.

 

Maximize performance where it matters most

SASE succeeds or fails at the edge, where users connect from homes, branch offices, mobile networks, rural areas, and other remote locations. While their expectations from your service likely don’t change based on geography, the quality of their connections often does.

In underserved regions with limited connectivity options, most traditional transit providers struggle to guarantee performance, let alone visibility or control. We bridge this gap with a dual-carrier strategy across these markets.

For example, in countries like Indonesia, Thailand, and Australia, we partner with domestic carriers to optimize last-mile latency and reach local ISPs, while also working with international providers to maintain reliable global connectivity.

This carrier diversity gives you the best of both worlds: fast, local access for your users along with robust, resilient global reach. It ensures your platform stays available, fast, and consistent, even in emerging markets.

It’s a key advantage when you’re expanding your SASE service into high-growth economies with fragmented carrier ecosystems and unreliable international transit. And by leveraging our established infrastructure, you won’t have to piece together regional transit solutions or juggle dozens of carrier contracts.

 

Add a private backbone when you need it

In most cases, Zenlayer’s premium IP transit gives you all the routing control and edge performance you need. But for some workloads, particularly those with real-time media, inter-region replication, or strict low-latency requirements, you may want even greater control over long-haul routes.

That’s where our 180+ Tbps global private backbone comes in. Spanning 140+ meshed points of presence (PoPs), our network reaches 85% of the world’s internet population in less than 25 milliseconds and is designed to support 99.95% uptime under our standard SLA. Higher SLA tiers are available for mission-critical workloads with elevated availability requirements.

Leveraging our backbone network lets you selectively route priority traffic across an ultra-low-latency, private network while keeping everything else on IP transit, empowering your operations with flexibility and performance without overengineering your stack.
