I use VyOS for a virtual router solution. VyOS solutions are great, and flexible.Throughput was a key requirement and Vyos delivered 10Gbps easily!The ability for VyOS to easily perform VLXAN and BGP was astonishing with its effortless ability.The greatest part was the VyOS support team. Excellent skillset and knowledge for in-depth network knowledge and ability to support clients through the VyOS platform.

I highly rate Vyos technically and its ability to perform the most complicated of requirements.

Customer Review

We’ve used VyOS for a decade now in all manner of applications, both physical and virtual. It powers everything from high-capacity LNS and Internet handoff with nearly a million BGP routes and multiple 10Gbps links to smaller virtualised instances right across the network.

Coming from a CLI background, the familiarity of its interface is a pleasant change from confusing GUIs, being simple to spin up an instance in just a few minutes but also able to create complex, yet easily understandable configurations. The guys at VyOS are a cut above and deserve a huge amount of credit for producing a best-in-class system that remains true to router-first principles while keeping clear from adding unnecessary bloat that plagues the current NGFW market. Looking forward to another decade with VyOS.

I use VyOS as a high-performance networking solution, and it has exceeded expectations in every aspect. VyOS delivers exceptional stability and reliability, effortlessly handling 10G interfaces without performance bottlenecks. Its support for BGP, VPN, and firewall features makes it a versatile choice for enterprise networks. One of the best aspects is how VyOS remains bug-free in production environments, ensuring smooth and uninterrupted operations. Additionally, the support team is highly skilled and responsive, making implementation and troubleshooting seamless. VyOS is truly a top-tier open-source networking platform that I highly recommend.

As an ISP, one of our most important use cases is to be able to run full BGP tables without any issues. We have been using VyOS for this for years now and it has worked absolutely flawlessly. I don’t think we’ve ever had an issue with this, in fact.

We also use VyOS to host a couple of hundred server-networks and VyOS handles this with ease, even with some of our networks having crazy amounts of access-rules on them and often having consistently high throughput and burst rates.

Whenever we do experience issues or we simply have theoretical questions, it never feels like the support team is far away. We usually receive very quick and concise answers to our inquiries. It’s a very nice feeling to know that everyone that’s working on the VyOS project seem to be experts at it, it does a lot for our confidence in running VyOS as much as we do.

I have nothing but good things to say about the VyOS Support Engineers. I think Dmitriy has owned our last 2 ticket, and the rest of the Support Team have all helped out. Taras, Yuriy, Jose, (and I hope I didn’t miss anyone) are quick to contribute and answer any questions I have. I believe it was Taras that even updated the VyOS/VMware doc to clarify a few things that I needed help understanding.

My boss just recently purchased a VyOS Subscription, or license, because we were experiencing a couple bizarre issues during our VyOS refresh of 30+ routers. We were struggling due to a single “show-stopper” issue, month after month, and not able to proceed with the rest of the refresh project. My boss, Daya Rajaratnam, decided we needed to get Commercial Support and open proper tickets and also to show our support of the VyOS Team.

Just hours after our Support PO went thru, I opened a ticket. I gave it a relatively low priority so I would know what to expect with future tickets. Its was great to see a response from an Engineer in just a couple hours. Fast forward a few days and the root cause was identified, I had a simple workaround in place and working in production(and had learned a lot from other Support Engineers that had contributed). What a HUGE load off my back to have that issue resolved with a reliable fix. 5 Stars for service, knowledge, and going above and beyond. (Hell, can I give them 10 stars?).

4 days later I opened a second ticket about an unrelated VTI issue that had also been plaguing us for many months. The experience was equally impressive and I again had a simple and reliable workaround.

Working with this group was a real pleasure.

I use Vyos from the beginning and his predecessor Vyatta. I like platform because has own style of architecture and similar cli like cisco and juniper.

I use platform to make migration from site to site or hybrid migration with Cloud.

I’d like that platform has all ipv6 attribute and use it very much.

VyOS is the backbone of our company network since the early Vyatta 6.x days. It scales to meet your needs – from 256MB Alix-Board Low-Power Box for small branch offices to multi-processor rackmounted/virtualized network appliance – and is extremely easy to integrate with other systems like monitoring and configuration management. The excellent support from Sentrium turns it into a truely complete product that meets all our requirements.

I’m happy to recommend VyOS/Sentrium. We first began using VyOS several years ago; we maintain a VPN from cellular vendor network to our infrastructure. Since moving our infrastructure permanently to AWS, we decided to sign up for Sentrium’s professional product and service.

I recently ran into a peculiar issue with the IPSEC VPN after a version upgrade – Sentrium staff worked with me to resolve it, and were very prompt in providing information and resolution. We are running two instances, a primary and a backup, and both are working splendidly, with seamless failover.

Thank you for the prompt support. It is great to know that not only the product is a perfect fit for our needs, but also knowing that there is a professional support team we can rely on.

We use VYOS to connect distributed POPs to our data centers and provide secure Internet connectivity to the POPs.

Resources

Here are some resources to help you learn more about VyOS, keep up with the development, and participate in it.

FAQ

  • Is VyOS free and open-source software?

    Yes. The complete codebase of the base VyOS system is publicly available under various OSI-approved licenses (mainly GPLv2 for executables and LGPLv2 for libraries).

    For the rolling release, we also maintain publicly available package repositories to simplify building images, so that contributors do not have to build images completely from source. For LTS releases, only the source code is available.

  • What platforms does VyOS support?

    VyOS can be installed on a wide range of off-the-shelf servers and network appliances. We provide special images for some hardware platforms. It also runs on all major hypervisors and cloud environments, including KVM, VMware, Amazon EC2, Google Cloud Platform, Oracle Cloud, Equinix Metal, and more.
  • What CPU architectures does VyOS support?

    VyOS currently only supports x86-64 CPUs. We may add support for aarch64 and RISC-V in the future, depending on the state of the network hardware and virtualization market for those platforms.
  • What are the minimum hardware requirements?

    The smallest amount of RAM that VyOS can boot with is 512MB. Trying to boot VyOS on machines with less RAM will result in boot errors.

    Otherwise, hardware requirements vary greatly between use cases. For small office use, low end CPUs and 1024MB RAM should be more than enough.

    For high performance routers, high end CPUs and large amounts of RAM are required.

  • What is the VyOS Release Model?

    There are two types of VyOS releases: the rolling release and long term support branches.

    The rolling release branch (git branch “current”) includes the latest code from maintainers and community contributors. It’s tested by an automated test suite and suitable for testing, home lab, and non-critical router use, but may contain experimental features that have not received extensive field testing yet and their config syntax and API may change.

    Long term support branches are periodically split from the current branch. They are stable, and only proven, strictly compatible changes are merged or backported into them. Their config syntax and APIs are guaranteed to remain unchanged, which is important for enterprise users and automation tools.

    Images of the rolling release are public, while long term support release images are only available to subscribers and contributors in binary form.

  • A VyOS LTS release is based on a Debian version that has reached end of support, does it mean that security vulnerabilities remain unpatched?

    VyOS release cycle is not synchronized with Debian and we often do have LTS releases based on Debian versions that reach the end of mainstream support before the end of our own LTS release support cycle. That does not mean that such releases are insecure. We are sponsoring extended LTS for those Debian versions from Freexian and we build many packages from source ourselves.
  • What is the release lifecycle?

    We produce a new LTS release about every two years. New LTS releases may feature significant configuration syntax changes — they are almost always automatically converted on upgrade so there is no need for manual migration, but automation tools may require adjustments for new LTS releases.

    Every LTS branch is then supported for at least three years, with a possibility of extended support if there is customer demand for it.
