Why VyOS?

We fundamentally believe that internet access is as vital to our human development as air, food, water, and healthcare. Built by engineers for engineers, VyOS is an open source software company that democratizes how we access networks so that the many, not the few, benefit from building solutions without limitations and prohibitive fees. We do this as VyOS through our open source software and virtual platforms.

“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.”

What Our Customers Say

Vyos Open source router and firewall platform
12 reviews

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 reached out to the Vyos team with an issue regarding my subscription and it was promptly resolved.

I have been using vyos for the past 6 maybe 7 years, came from pfsense and never looked back.

The most important features for me:

  • Ease of use
  • I can configure everything from the command line and have made small modifications as time has gone by. I keep a script with the full command set applicable to my firewall.
  • QoS
  • Setting up fq-codel is extremely intuitive and works flawlessly. I never had this kind of QoS with other solutions.
  • I do miss a web interface to display stats and such, but I can live without it for the time being.

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.

Paul Theodoropoulos

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.

Dan Shechter

I think you have a great product. Actually I like promoting your product to other customers and using it for demo purposes.

You are one of a kind today to support almost all network protocols.

You guys are great on support. Thank You.

Anthony Grevich

We are very excited about VyOS and use it as part of our products. VyOS convinces as a complete product with REST API and Wireguard support. The support is very fast and extremely competent.

I’ve been using vyos since 2013. I was looking at purchasing a couple of other hardware devices from a vendor that sounds like Jupiter. There were several licensing restrictions and extra costs that would have gone into the project, but thanks to Lanner electronics and vyos, the cost dropped by about 75% and we didn’t have to worry about extra licensing to do what we needed. I’m pretty much s novice when it comes to the network and network security side of the house, but our very experienced network team was more than impressed with vyos. And they were able to, not only complete, but add features, to our installation for several hundred workstations using 5Gb of bandwidth across 4 sites. Myself and a team with over 60 years of combined experience can’t recommend it strongly enough.

VyOS is very useful for teaching IP routing basics at the University of Applied Sciences Esslingen. The command line interface is easy to learn and convenient to use. And VyOS includes all IP routing features required in the lab (KTlab at University of Applied Sciences Esslingen).

Startet with Vyatta and now moved to vyos.
Have bin using Vyatta/Vyos on hardware/VMware for many years. Also using Ubiquti routers.
We are using Vyos in our education.

VyOS has been my go to virtual router distribution ever since vyatta got acquired. I love their new business model which makes sure the project stays afloat while still giving the community all the features being developed without restrictions.

Fahad Yousuf

I looked for an Opensource router with power ful command line.
So I found VyOS with lots of essential features like: BGP, RPKI, OSPF, IPSec and recently support MPLS in beside of very easy command line.

Started with Vyatta subscription in 2008. Upgraded to VyOS and still running. (BGP)

Apr 23, 2020

I’ve used VyOS (Vyatta) since 2014. It was the primary routing platform in an organization that supported 100+ sites and over 40,000 users. There is a learning curve for some who have come from a traditional environment, but it is an extremely flexible networking platform.

Robert Guice

Excellent Product. We have been using VyOS for couple of years for IPSec, BGP, Firewall, NAT etc features. Very stable and very easy to use.

Alberto Benedi

We are working with VyOS (previously Vyatta) since 2014 and in general we are very satified.

VyOS is a great product. It’s very community driven. The only small downside at the moment is that some legacy staff needs to be reworked until the focus really could be set to the future.
But a lot of things are already changed.

Markus Berthold

VyOS has proven to be very reliable over the last 8 years we use it (starting with Vyatta).

Very reliable routing software with great community and support.

Christian Eich

Vyos is my go-to distro when setting up routers. Everything works out of the box, the installation process is simple and in a few minutes you’re good to go.

The development is really active, and you can easily reach the devs and the community through the forums if you need.

Excelent system and team.

Josué Conti

What an awesome Swiss-Army-Knife of a solution!
I’ve been using Vyos since the early days. It is an incredibly flexible, useful and stable router.

Very impressed with the recent re-shuffle, re-branding and formalizing of the commercial support model.

It will no-doubt bring Vyos on-par with other high-quality commercially-supported open source tools. In my view, better than your average Cisco/Juniper/Edgemax router.

Very active development as of now in 2020. Great software.

Apr 15, 2020

Awesome Job guys.

Apr 15, 2020

Over the last two years of so, VyOS has become my go-to for a wide range of use cases, ranging from a simple home router all the way up to using it for private to public cloud connectivity on AWS, Azure and GCP. It’s also a great VPN appliance for road-warriors.

It doesn’t matter what I throw it on, KVM, Xen or VMware hypervisors, or bare metal Xeon, Xeon-D and below… it just works.

VyOS kicks … you know what. I hope you’ll decide to support the project too.

Orlando Amador

VyOS is my go-to router distribution. I use it at client sites, at home, and would not hesitate to recommend it for most router/firewall needs. It runs superbly well on small low powered hardware as well as larger servers. I have never used or needed the paid support, but for a mission critical installation I would think it would be beneficial.

Ruel Tmeizeh

Great !

Used as bgp router and also in a different box as vxlan with great performance.

Xavi Céspedes

Amazing! Several features on a single platform.

Renan Ledo
Apr 14, 2020

We have been using Vyatta/VYOS for years now and recently started participating in paid support program. We are happy to do this as we think it is important to financially support good open source software. I have had a couple of support issues thus far where I was not able to easily find the answer I was looking for on the web. I could have taken more time to look, but instead I was able to open up a quick line of communication to the VYOS support team. Their response has been prompt and thorough and truly interested in answering the question versus just moving through tickets. Great Job!

Reliable substitute for physical routers.

Richard Bollinger
Apr 13, 2020

It is an all in one networking solution for our remote branch office connectivity and corporate access. It can be nearly deployed everywhere (clouds / virtual appliance/ physical device). It is a perfect choice to add to your tech basket if you are a development-aware IT guy or an IT-aware developer. The development team are very supporting both technically and humanely.
You may interact in their slack channels with the contributors and product owners as well as file and watch the issues in their phabricator.
Although they offer official builds via subscription, you are allowed and may achieve the same build in DIY manner via the instructions for free. They also generously offer free subscription to support the soul of contribution to heavy contributors. Their recent empathy to offer free subscription and setup help for organizations falling into remote work category due to COVID protections is just an example of what makes you feel attached.

Apr 13, 2020

VyOS is an excellent virtual router and we have made it a staple of our IT systems; using it almost everywhere!

John W Kerns

Thank-you for VyOS! Stable, lots and lots of production level features, well thought-out cli contexts, config is readable, system is scriptable, easy access to tcpdump, easy to back-up and restore, great price.

Perryn Gordon

Perfect and fast OS for routers. Using it widely in our internal and external infrastructure, never had any kind of serious issues with it.

Kirill Kulbatskiy
Apr 13, 2020

You guys have been great to work with but you are making the wrong decision with T2100 to not set check igp as default. Every other BGP implementation does this. The feedback I am getting from the networking community says that no one wants this and I have demonstrated how it breaks BGP networks. This breaks BGP in a subtle way that only becomes apparent during a reroute. I am giving this feedback to help you improve.

Ben Russell

Is VyOS 1.2 outdated because of Debian 8 release schedule?

Debian 8 is in the EOL state by the community maintainers, but it is still supported commercially. All the software from Debian 8 that we need for VyOS 1.2 is still supported by and it receives security updates.

Apart from this, there is still a very big difference between Debian 8 and VyOS 1.2 – VyOS 1.2 uses Debian 8 repository for some of the libraries or system daemons, but the most important parts for the router – kernel, routing daemons, many networking services built by us, and do not have anything common with Debian 8.

Therefore, VyOS 1.2 could be detected as EOL Debian 8 by some software, but it is supported and not affected by Debian 8 security issues.
