road map product roadmap – new features, release notes and more (as always, a work in progress)

Published on 18 mins Last updated

Understandably, we get quite a few requests for a product roadmap containing release notes and feature updates. We've had a chat about this internally and thought that it would be nice to have a permanent post on the blog that we change on the fly as and when customer requirements change.

Putting this on the blog enables our customers to express their arguments for and against new features etc.

This entry should also give you a better idea of our priorities and how we develop the product.

You can jump straight to our latest update (v8.9.1) here ->

We've changed our focus from v9 later to v8 now...
And we've doubled the size of our development team, which means that we can bring new features to you quickly. We are also changing the way that we release product updates. We have moved to a regular quarterly release cycle, to enable a more rigorous approach to quality.

In the event that we need to provide a release to mitigate against a serious security vulnerability, you will be informed and the release will be made off-cycle.

So what can you expect in the next few months?

We've recently added a some really useful template deployment functionality. We aim to gradually improve this to support our partners with large and rapid deployments.

We've just completed a huge overhaul of the backup & recovery functionality. The focus being to make it as simple and flexible as possible. Making it far easier to automate and test deployments, and be ready for centralized management. And we finally added Prometheus support, for external graphing and analytics.

After making sure that Software Updates can Rollforward, we are now working on the Rollback. And most importantly we're tidying up centralized management before general release of our cloud portal.

And we’ve got time to add more..
So shout now if you want something changed — you can contact me directly by emailing

How do we decide what to do next on our priority list?

Our principles always guide us, this is an overview of the things we feel are most important in a load balancer appliance in order of priority:

  1. Security
  2. High-availability
    • Constant improvements to underlying systems
    • Future enhancements to intelligence, logging and alerting.
  3. Maintenance
    • Constant focus on close to zero downtime for maintenance and security updates
    • Helping the customer carry out software updates on servers in the cluster.
  4. Performance
  5. Support
  6. Usability
    • Improvements to look and feel + intelligence and ease of use
  7. New platforms
    • Integrate new platforms as and when they become customer priorities i.e. azure
  8. New features
    • Assess against our priorities and implement if, and only if they match our stated priorities.
  9. New products
    • Constantly looking for new applications to help customers with their infrastructure requirements.

Hang on, what happened to v9?
The fabled v9 has evolved into our Partner Product, a customizable, and modular solution that simplifies large scale deployment. It’s already seamlessly embedded into hundreds of critical systems across the globe.

In fact it's grown into a bit of a monster. So while we prepare version 9 for general availability, we have decided to accelerate development of v8 to bring you new and exciting features.


So, what exactly is our partner product?

Put simply, our partner product is a platform for application delivery.
But more importantly it's something we create together — with amazing results. After all not every partner needs all of our services:

  • API driven, vendor agnostic, data plane agnostic centralized application delivery
  • Fully automated deployment, maintenance & monitoring of your applications
  • Tight integration with your development team and your roadmap
  • Our support integrated with your customer service team
  • OEM Hardware development, deployment, certification and logistics
  • Centralized management of security and version control
  • Flexible contracts with long term commitments to your roadmap

Why do you need our partner product?
You are a respected technology vendor in your sector. And you have a large number of customers depending on your systems. And it's getting increasingly complex to support them on a global scale — while keeping the pace of innovation going with your own product roadmap.

I'm sure your system has unique requirements:

But wouldn't it be great to work with someone who wants to help you increase your revenue & customer satisfaction, while reducing complexity & costs?

Don't worry: We'll still be updating & supporting v8 for a very long time!

In the process of designing our WAF implementation we've been having a lot of conversations with Sucuri, these guys are awesome and know everything about web application firewalls and denial of service protection. Sucuri are also way more friendly than Incapsula (who were impossible to get any straight answers from).


  • More wizards for setting up specific applications
  • Dynamic graphing and dynamic numerical stats
  • Re-write and enhancement of the initial configuration wizard(s)
  • Layer 7 email alerts - as usual we've released it open source before actually putting it in our product (how do we make any money anyway?)


  • Re-write of the security model for pairing master and slave units - for full security compatibility with cloud platforms AWS and Azure.


  • Overhaul of system overview
  • Loads of improvements to the web interface in general, making it easy to use as well as nice to look at

  • Performance and functionality improvements to the windows feedback agent
  • Port of the full product to Microsoft Azure cloud platform - in progress but trying to make the Kernel secure without access to the Microsoft source code is fun!

Other previous updates....

  • SNI support in the web interface
  • WAF / Mod_Security: We've ensured that our Layer 7 rate limiting enables seamless protection for each WAF instance by default, because the last thing we want is the WAF itself being an easy way to DOS our load balancer!
  • Simple ACL redirects and rules with support for manual backend configurations
    API & LBCLI improvements
  • AWS - automatic one click integration with auto scaling groups
  • Complete re-write of the disaster recovery functionality - NO DOWNTIME!
  • Several performance enhancements for specific types of traffic.

And then we have some features on the soon to be scheduled / wish list:

  • Full re-write of the high-availability subsystem (heartbeat) focusing on stability and scalability and intelligence for multiple nodes.
  • Plug-in architecture and wizard for controlling the auto-scaling of backend servers in clusters - that would be fun/interesting.
  • Enhancements and intelligence into real server health monitoring
  • Easy to use Denial of Service rules- manual config.
  • Simple rules to direct users to different clusters when the primary one is busy i.e. busy e-commerce site flood control - manual config.
  • Easy and secure remote access to customer load balancers from support staff
  • Easier integration of existing authentication methods i.e. RADIUS/LDAP/Active Directory

Things we are not doing:

  • SNORT - Why? But we might make DDOS protection more automated..
  • iPhone/iPad/Android apps
  • Graphical firewall
  • Firewall load balancing - we could ask Horms very nicely to modify the Linux Kernel for this...maybe...
  • Bridge based load balancing - yuck...But a LOT of people use web filters and WAFs in bridge mode so something like the Net Optics xbalancer solution makes sense.
  • Link balancing - really? I don't think so. And here's why...
  • TMG SSO replacements - Yuk. Although, Andrew might look into doing this during his downtime (our developers get 14 hours a week free/fun/downtime).
  • Making anything more complicated, or harder to use....

Obviously, this blog post needs a lot of work...and will change rapidly...please comment below, thanks.
