Now these factors have led to increased volatility in management:

1) Increased Cyber Risk EXPOSURE
2) Compliance with Cyber-related LAWs and REGULATIONs
3) Risk of litigation and Directors' and Officers' LIABILITY arising out of the above

At the same time, business, project and deal must be committed to continuous improvement and upgrading.
Damage to IT assets, which are a source of value for a company, can lead to significant opportunity loss, reputational degradation, and spillover of losses to the supply chain.
Management must recognize, assess and measure cyber risks in compliant with relevant laws and regulations, and implement both technical and organizational aspects.

Cyber risk has traditionally been tackled as an issue specific to IT departments. However, a high degree of expertise is now required that goes significantly beyond that.
And, cyber risk, which is one of the key management issues, requires the use of professional services with highly specialized knowledge, experience and technology.
