Announcing Profian

Profian, a security start-up in the Confidential Computing space

I’m very excited to announce Profian, a security start-up in the Confidential Computing space that I co-founded with Nathaniel McCallum, came out of stealth mode today to announce that we’ve completed our Seed Round – you can find the press release here. This is the culmination of months of hard work and about two years of a vision that we’ve shared and developed since coming up with the idea of Enarx. Profian will be creating products and services around Enarx, and we’re committed to keeping everything we do open source: not just because we believe in open source as an ethical choice, but also because we believe that it’s best for security.

Enarx grew out of a vision that we had to simplify use of Trusted Execution Environments like AMD’s SEV and Intel’s SGX[1], while not compromising on the security that we believe the industry wants and needs. Enarx aims to allow you to deploy applications to any of the supported platforms without needing to recompile for each one, and to simplify both the development and deployment process. It supports WebAssembly as its runtime, allowing a seamless execution environment across multiple hardware types. Engineering for Enarx was initially funded by Red Hat, and towards the end of 2020, we started looking for a way to ensure long-term resourcing: out of this Profian was born. We managed to secure funding from two VC funds – Project A (lead investor) and Illuminate Financial – and four amazing angel investors. Coming out of stealth means that we can now tell more people about what we’re doing.

Profian is a member of two great industry bodies: the Confidential Computing Consortium (a Linux Foundation project to promote open source around Trusted Execution Environments) and the Bytecode Alliance (an industry group to promote and nurture WebAssembly, the runtime which Enarx supports).

The other important thing to announce is that with funding of Profian comes our chance to develop Enarx and its community into something really special.

If it’s your thing, you can find the press release on Business Wire, and more information on the company press page.

A few questions and answers

What’s confidential computing?

I tend to follow the Confidential Computing Consortium’s definition: “Confidential Computing protects data in use by performing computation in a hardware-based Trusted Execution Environment”.

What does Profian mean?

It’s Anglo-Saxon, the language also sometimes called “Old English”, which was spoken in (modern day) England and parts of Scotland from around the mid-5th century BCE to 1066, when Norman French had such an impact on the language that it changed (to Middle English).

One online Anglo-Saxon dictionary defines profian thus:

profian - 1. to esteem; regard as 2. to test ; try ; prove 3. to show evidence of ; evince

It’s the root of the English word “to prove”, from which we also get “proof” and “proven”. We felt that this summed up much of what we want to be doing, and is nicely complementary to Enarx.

How is Profian pronounced?

Not the way most pre-Conquest Anglo-Saxons would probably have pronounced it, to be honest. We (well, I) thought about trying to go with a more “authentic” pronunciation, and decided (or was convinced…) that it was too much trouble. We’re going with “PROH-vee-uhn”[2].

What does Enarx mean?

You’ll find more information about this (and how to pronounce Enarx), over at the Enarx FAQ. TL;DR – we made it up.

Who’s part of the company?

Well, there’s me (I’m the CEO), Nathaniel McCallum (the CTO) and a small team of developers. We also have Nick Vidal, who we recruited as Community Manager for Enarx. By the beginning of October, we expect to have six employees in five different countries spread across three separate continents[3].

What’s next?

Well, lots of stuff. There’s so much to do when running a company of which I knew next to nothing when we started. You would not believe the amount of work involved with registering a company, setting up bank accounts, recruiting people, paying people, paying invoices, etc. – and that’s not even about creating products. We absolutely plan to do this (or the investors are not going to be happy).

No – what’s next for this blog?

Ah, right. Well, I plan to keep it going. There will be more articles about my book on trust, security, open source and probably VCs, funding and the rest. There have been quite a few topics I’ve just not felt safe blogging about until Profian came out of stealth mode. Keep an eye out.


1 – there are more coming, such as Arm CCA (also known as “Realms”), and Intel’s TDX – we plan to support these are they become available.

2 – Anglo-Saxons would probably have gone with something more like “PRO-fee-an”, where the “o” has sound like “pop”.

3 – yes, I know we’ve not made it easy on ourselves.

  1. Congratulations! So exciting; I look forward to hearing more about progress in the future.

    I can’t help but obsess over your ligature; is there some secret meaning embedded there as well?
