Cloud has removed the concerns of end users around capacity limitations, accessibility, and availability. This is giving them the freedom to operate in a manner they always wanted to. When you add AI and analytics into the mix, the end user now has platforms that scale as per their need while allowing them to better analyse what they do so they can make better immediate and future decisions.

The pandemic has moved the workforce from the office to home and organisations had to relax their security policies to allow their employees to work from home and access corporate resources to be able to do their work. This has led to a significant increase in cybercrime across the globe.

Understanding and managing convergence of IT and OT is a critical area for decision makers to skill themselves in

According to an Interpol Assessment, there has been a major shift in Cyber Crime targets during covid-19 from individuals and small businesses to large enterprises and critical infrastructure. This clearly underlines the importance of further investment in end-to-end cyber security, especially in OT, which has been somewhat neglected over the years, as it is converging more and more with IT.

Understanding and managing the convergence of IT and OT is a critical area for decision makers to skill themselves in. Organisations are no longer siloed and delivering on this converged strategy is what will differentiate decision makers and organisations. As IT and OT worlds rapidly converge, there’s no better time for security decision makers to seize the opportunity to support their organisation’s efforts to improve operational resilience by adopting integrated security strategies across IT and OT.

Gaining a better understanding of OT systems and gaining specialised skills to better assess and support the unique requirements of industrial networks help strengthen security and resilience across IT, OT and IoT networks.

5G is one to watch. 5G will accelerate digital transformation. 5G will give businesses constant access to faster, more reliable internet connectivity – a much needed tool to effectively support remote work scenarios. It also opens the door to massive interconnectivity.

Millions of devices, networks and data transfers supporting process flows and transactions. While this mass-scale connectivity will drive greater business efficiency, it also increases cyber risk and the potential for more significant breaches. Security strategies must evolve to meet the challenge. Solutions must scale and deploy quickly and endlessly as devices are added and support centralised management and monitoring.


CISOs are responsible for the security of the whole organisation including OT. The vendor’s solution provides the CISO with visibility and security into the OT network allowing them to secure the OT network while having visibility into any threats and attacks. The vendor provides the CISO with the confidence to make the right decision for their OT environment while enabling them to converge IT and OT.


There is no better time for security decision makers to improve operational resilience by adopting integrated security strategies across IT and OT.
