The theme of this year’s roundtable was security vulnerabilities – many of which have been deemed critical over the last 12 months.


This is enough to give security teams some serious sleepless nights. Zerologon, F5 BIG IP, SigRed and multiple vulnerabilities in Citrix are just some of the big-name vulnerabilities that were disclosed.

To talk through the subject matter we were delighted to be joined by our panel of experts, who explored how 2020 compared to other years when it comes to vulnerabilities and the risk they pose to organisations. The panel also discussed underlying vulnerability and technology trends, and looked into the future to predict what vulnerability management challenges lie ahead for organisations in 2021.

Press coverage

The roundtable event was covered by the national cyber security media:


Ethical Hacking Roundtable 2020

As a counterbalance to misconceptions about ethical hacking, in 2020 Redscan decided to bring together a number of cyber security experts to consider the state of the industry and examine current risks, challenges and trends.

The panel discussed what constitutes ‘ethical’ in the context of hacking, the benefits of hacking to businesses and society, where the boundary lies between legal and illegal activity, and other hot topics.
