7 reasons why the probability of a high-impact cyber incident has never been higher


Criminals have industrialized


Criminal supply chains sell access as a service, and providers make it easy to get into the ransomware game.


Attackers now use nation state tools


Supports our unique approach of using using our offensively-trained threat hunters to defend networks.


The average cost of a data breach in 2020 was $3.86 million


That’s not counting the fines for data loss – Marriot and British Airways both faced $100 million fines for GDPR violations as the result of a breach.


It’s not just data that goes missing in a breach


40% of the cost of a data breach comes from loss of business.


Every organization is now a target


Attacks like that on Solarwinds compromise multiple organizations – in this case over 18,000 – creating massive collateral damage.


Ransomware continues to grow as a threat


Increasingly sophisticated attacks are taking place at mammoth scale and pace.


Many organizations can now detect – but not respond


Incident Response teams are often brought in too late to respond – instead they are left to pick up the pieces and perform recovery, not response.
