Cariad Keigher


Hi! My name is Cariad Keigher (kayr-ree-ad kee-yer) and I am a Senior Security Analyst at one of Canada's largest natural resource companies. I've been working in the information security space for the past decade and believe that community via information sharing is the best approach in working against current problems facing cyber security. This can be achieved either through information sharing and analysis centres, online communities, and even to a certain extent conferences.

Previously, I've been a consultant for a small boutique cyber security firm, a support engineer at an anti-virus company, and a systems administrator at a local managed service provider. I've also ran a service that parsed and stored leaked data from system breaches released to the Internet.

Outside of my day-to-day job, I have an interest in roller skating (specifically roller derby), vegan cooking, video games, queer issues, and intersectional feminism. I use "she" and "her" pronouns and I like to write code using Python and work on old computers--I have a long-standing project to modernise a Macintosh Quadra 800.

My primary language is English. I hold citizenship in both Canada and Ireland. The content expressed on this website is representative of my own opinion unless specified otherwise and not of my employer or any organization I associate with.

Outreach and publicity

Working in cyber security can sometimes get you a lot more attention than you desire. I've appeared in a few publications and have spoken at a few conferences and companies.

Here is a sampling of times where I appeared in the media:

I have some of my conference talks listed here:

I should note that my former legal name and previously assigned pronouns are mentioned in much of what it is linked here. I ask that you do not use this name when referring to me as that is no longer valid and to also stick with the aforementioned "she" and "her".

It's very rare for me to speak to the media even considering the above. The Forbes article was the last time I bothered to give an interview to a journalist.

Contacting me

My primary means with interacting with the Internet is via my Twitter account. It isn't meant for professional purposes but from time to time I will talk about information security or share something other than queer issues, weird video game stuff, or photos.

If Twitter isn't your forté, I am available via e-mail but please be aware of the following:

If you're okay with the above, feel free to e-mail me:

You can also reach out to me via Google Hangouts, Signal, Telegram, Discord, and IRC. I give these details out quite sparingly although I use "katelibc" on most IRC networks including Freenode.

I'm periodically at conferences and meetups, and am happy to meet with people but please understand that I am usually pretty busy at these events and will only be able to make time for you if I can.


Should I ever run into a situation where I lose control over a service such as Twitter, I have a SHA256 hash below that I'll reveal:


Proof of its existence elsewhere can be found in this tweet from May 2018.
