## Auditable zero
trust security

Say goodbye to IP-based access control, perimeter firewalls, and buffer overflow exploits. Say hello to workload identity, end-to-end encryption, and deny-by-default security policies.

Learn more

## Ultra-high
availability

Scale out across multiple clusters, remove single points of failure, dynamically redistribute application traffic in response to latency or instability, and transform your Kubernetes platform into a truly resilient distributed system.

Learn more

## Network and cloud
cost savings

Decommission expensive application load balancers, reduce cloud costs with zone-aware load balancing, and reduce latency—all without sacrificing reliability.

Learn more

## Production-ready
service mesh

Buoyant Enterprise for Linkerd is our production-ready distribution of the open source Linkerd service mesh, built for sustained use at scale and long-term commercial support.

## Why Rust?

Why the future of the cloud will be built in Rust

by Buoyant CTO Oliver Gould

According to the US Cybersecurity & Infrastructure Security Agency, an astonishing 70% of serious security bugs are memory vulnerabilities —a problem that is endemic to software written in C and C++.

‍

Linkerd is the only service mesh built in Rust, a memory-safe language that protects against precisely this type of vulnerability while being just as fast (if not faster!) than C and C++.

‍

After all, the platform of the future can't be built in the language of the past.

Linkerd avoids memory safety bugs by using Rust

Google’s Chromium project found that 70% of serious security bugs are due to memory safety problems.

## We're committed to open source

Say goodbye to IP-based access control, perimeter firewalls, and buffer overflow exploits. Say hello to workload identity, end-to-end encryption, and deny-by-default security policies.

Learn more

We’ve been leading the charge for introducing Rust to the cloud native space. Linkerd’s innovative microproxy approach is powered by Rust, allowing us to deliver lightning-fast performance without the security vulnerabilities of languages like C++.

Learn more

We contributed Linkerd to the Cloud Native Computing Foundation in 2016, and in 2019, Linkerd became the first service mesh project to achieve graduated status in the Cloud Native Computing Foundation, the highest level of maturity possible.

We had the Linkerd multi-cluster up and running within an hour! After a few days of struggling with Istio, we gave up on it. Linkerd did the job fast and easily — the perfect mesh for us. It had all the features we needed at the time, was easy to operate, had a great community, and solid documentation.

Unlike other service mesh offerings that crowd half baked features into the mix, or over-complicated topology choices, Linkerd follows the Unix model of doing one thing well, in a composable way. Lachlan Smith, Lead Software Engineer
