About

G'day — I'm Alex.

Originating in Sydney, Australia, I'm now working for Wise in London as a Senior Security Engineer. I spend my days deep in detection engineering, and my nights building tools to make the rest of the SecOps world a little more secure.

Sigma

In the spare time in-between life, I’m helping build and educate others about Sigma – helping detection engineers get the most out of their SIEMs.

Explore Sigma

A generic and open signature format that allows you to describe relevant log events in a straight-forward manner.

Introducing Sigma Filters

Sigma Filters are an extension of the Sigma detection format to allow you to compose common exclusions for your SIEM rules.

Sigma: Decoding the Future of Detection

I recently completed my first two BSides talks this year, and based on the fantastic questions and responses I got from the community, I decided to make the slides available here. Thanks to everyone who showed up and gave support!

I’m also building a startup – north.sh – A new platform for SecOps teams. I’ve always been a believer in building the change we want to see – and what place better than keeping the world more secure.

The New SecOps Platform – north.sh

All your SecOps alerts, correlations, aggregations, vulnerability data & threat intelligence, all in one single platform.
