Danny Dresner

Professor of Cyber Security, University of Manchester

I find the threads that bind information together and mend them when they break. I’m Academic Cyber Security Lead at University of Manchester, director/co-founder of IASME-the SME benchmark of cyber security governance-that helped to pioneer the Cyber Essentials. An evangelist for useful standards and good practice, I nurse organisations through ISO/IEC 27001. I received a PhD for work in information systems risk. A Fellow of the Institute of Information Security Professionals. I was at The National Computing Centre for 22 years, architect of DTI’s Towards Software Excellence programme, created the core of SANS’ training for BS 7799, edited national security breaches surveys (from 1994), and wrote the first standards for source code escrow. My contribution to NCSC risk management guidance is noted, I’m an active member of IAAC’s North West cohort (creating a Northern Academic Liaison Panel). I’m active in Yorkshire’s Cyber Security Cluster, revived The Ratio Club, and a director of a neurodiverse community SOC. I’m part of GMCA’s Cyber Foundry realising aspirations for a resilient, cyber secure, digital community and economy.

My work spans public, private, and third sectors. It varies from identifying vulnerabilities (and how to fix them) of a small firm responsible for 7 million personal records, to writing a definitive guide to cyber resilience for local government (for SOCITM). I’ve contributed to books, conferences, and appear on the BBC to explain risks and opportunities of information systems to the wider community. I was voted the UK’s second top influencer in cyber security in 2017, and eighth and eleventh internationally in 2018 and 2019 respectively.

When not securing information, I work for the security of my children and my parents’ honour. Personal interests range from Jewish tradition to science fiction. My knowledge of Doctor Who lore is tiring; I was graphic artist for the Blake’s 7 Appreciation Society which just goes to show…

Greg Keller

Greg Keller

Chief Technology Officer, JumpCloud

A start-up veteran and experienced executive with a proven track record of building new high-scale businesses and strong product teams while delivering profitable growth.

-Software. Teams. Companies.-
From start-ups to great teams to software products, I have enjoyed building lots of things…and often from virtually nothing to start with. True ‘barn-raising’ experiences should be had by every software professional in their career to understand how it all comes together and grows. 

-Product Management and Product Marketing DNA-
I’ve heard a couple of mantras on the concept but to me product management boils down to “supplying customer demands profitably”. For two decades I’ve enjoyed solving tough problems faced by my customers and rallying teams to get it all done, on time and with super high quality is the rush. 

-Technology Evangelism and Speaking-
I’ve been fortunate to have traveled the globe speaking about technology. If I am intellectually curious about a problem, it simply has to be digested, vetted and expressed…and most often this occurs in front of audiences with equally curious technologists.

-Executive and Team Management-
I don’t make it a mission to climb ladders. Never have. I just talk to people the way I would like to be talked to and it seems to end up sending people off in the right directions to execute and get it done. Leadership is empowering those you manage and then you get out of their way. This always ends up helping to steer the company up and to the right.

-Making my ‘product users’ into ‘product champions‘-
The joy of my life. Communing in person with your market and user base to listen and see first hand what they need, how they use your product and what they think could improve their efficiency using it, is the only path to truly building a great solution.
