It just does an amazing thing putting our website to top speed, which is a significant factor in improving our search rankings. It also helps decrease memory usage and we have lesser downtime errors now, too. Configuring our system for optimal performance has also been easier with this software.

Documentation can be improved to provide more details. Also, https should be natively supported because this is a standard to all websites these days. While there is a well-detailed manual, only our senior developers have had luck in managing this software, so maybe it should be more user-friendly or the UI can be updated.

Varnish is really fast and powerfull . The Varnish Configuration Langage (VCL) is a must (think embedding Javascript to configure the cache). You can do everything with it.
I use varnish for caching popular content (VOD, Live, Static Assets) on hundred of servers, but also for Load Balancing API. Varnish support also distributed and multi-level of caching.
I haven't found any problems in many years. The support is fast, and helpfull. The support come from the developper so it's very easy to find issue with our hardware. Review collected by and hosted on G2.com.
It's difficult to find a flaw for Varnish. Perhaps the cost of the solution ? But when i see the number of times i've open a ticket (3 in 8 years) I think the value is well spent. Review collected by and hosted on G2.com.
The Cache HA Cluster and ESI (Edge Side Includes) features are often considered among the best aspects of Varnish Software due to their capability to optimize web performance and manage content delivery efficiently. Review collected by and hosted on G2.com.
One drawback of Varnish Software is the lack of native support for Kubernetes as an ingress controller. While Varnish offers advanced routing, caching, and other features, its compatibility with Kubernetes and cncf solutions is limited, which can hinder its seamless integration within Kubernetes environments. This limitation could potentially be addressed to broaden the software's usage. Review collected by and hosted on G2.com.
Our web servers have become faster and more responsive thanks to Varnish software, this cuts down the waiting time for our pages. We managed to cope with large traffic spikes without any interruptions. Review collected by and hosted on G2.com.
The only minor drawbacks I can think of are related to the aggressive caching approach. This approach sometimes requires custom code to make it suitable for automatic cache invalidation using cache tags. Review collected by and hosted on G2.com.

This results in faster page load times and improved user experiences. Review collected by and hosted on G2.com.
I have found it to be resource-intensive , particularly in memory usage. Review collected by and hosted on G2.com.
It is flexible, securing our web development from request to response from client to backend and back again. Cost efficient, fast load to clients, low usage of backend infrastructure. High availability. Review collected by and hosted on G2.com.
Very hard to say anything less good about Varnish. It's a technical product, built by technical people for technical usage, But make everyone happy from technicians to end users. One thing is that is so in front line of services to manage subscription thats its harder for a large company with security regulations to manage installation media and patches, but that problem is more on our side rather than problem with Varnish.

Varnish Software is very flexible and highly configurable product which makes it possible for one to configure it based on your specific needs so as it can fit your specific requirements. It was super easy to set-up and within a short period of time, it was up and running. The customer support team is always at our heals to offer any kind of assistance that we might need.
