Announcing Leadership Changes at Cosive: Farewell to Kayne Naughton and Welcome Scott Ceely
July 17, 2024

We wanted to take a moment today to update our community of past and present customers, as well as our professional and personal networks, of recent changes to the Cosive board.

Farewell Kayne Naughton

After nine years on the Cosive board, Kayne Naughton, one of Cosive’s three co-founders alongside Terry MacDonald and Chris Horsley, has stepped away from the company to pursue his technical research interests.

Terry MacDonald has stepped into the Managing Director role.

The entire Cosive team would like to thank Kayne for his dedication in making Cosive the company it is today.

We will be cheering Kayne along on this new path, which will allow him to do more of what he loves full time: being on the tools and exploring new frontiers in technology.  We still plan to work together on projects where we can combine our collective skills.

Welcome Scott Ceely

We are excited to announce that Scott Ceely has joined Cosive’s newly formed advisory board, bringing with him extensive leadership experience in cybersecurity consulting.

Scott Ceely has worked in cyber security for 25 years. Scott was co-founder and Managing Director of Seer Security, which was acquired by Tesserent in 2020. Prior to launching Seer Security, Scott was responsible for building the AsiaPac presence of the UK-headquartered firm Context Information Security.

During his time in Federal Government, Scott held a variety of technical and managerial positions, including as a technical liaison officer in the Australian Embassy in Washington DC.

Scott is passionate about talking security at all levels: from boardrooms to classrooms.  As a result, he was an inaugural board member of CREST Australia, participates in CSIRO’s ICT in Schools program and speaks at a variety of public and invitation-only security conferences and on expert panels. Scott now spends his time advising Australian businesses, and in his spare time, can be found on a motorcycle somewhere near Melbourne.

In welcoming Scott Ceely as an advisor we gain the knowledge, experience and industry perspective of one of Australia’s most accomplished cybersecurity entrepreneurs.

The establishment of our advisory board ensures we are well-equipped to accelerate into the next stage of Cosive’s growth as a leader in cyber threat intelligence and Security Operations excellence. We are delighted to have Scott on board and helping to guide our strategy into the future.

The Opportunity Cost of Self-hosting MISP

A term with origins in macroeconomics, opportunity cost is the hidden cost of choosing one course of action over another, when both cannot be chosen at the same time. Opportunity costs are not always financial. For example, the opportunity cost of playing video games instead of going for a hike are the benefits you’d have likely gained from hiking, such as improved fitness and mental health. Security teams also incur opportunity costs whenever they pick one way to spend their time and resources over another. The opportunity cost of self-hosting and maintaining MISP is the additional time and brainpower teams could have otherwise spent gathering and leveraging usable threat intelligence and enhancing their organisation’s security posture.

Running Your SOC Playbooks as Code: Use Cases, a.k.a. Don’t Start With Phishing

The first thing that everyone wants to do when they get their brand new SOAR out of the shrinkwrap is solve phishing. I hate to be the one to break it to you, but if we were going to solve phishing, there wouldn’t be six or so anti-phishing vendors out there right now. (Technically malware was the first computer security problem that we struck, with the Morris worm, but in terms of things that face regular users, phishing is the first problem. Paul Graham first started applying bayesian analytics and machine learning to this stuff in the 90s, or something crazy, and we still haven’t solved it yet.)
