Reliance on artificial intelligence (AI) to combat cybersecurity threats looks set to increase by several orders of magnitude over the next few years. A recent report from P&S Market Research suggests that the global AI cybersecurity market will reach US$18.1 billion by 2023. As the overall size of the attack surface continues to expand, it's simply not feasible for cybersecurity teams to defend against every threat without some additional help. AI's playing an important role in helping automate threat detection and response, which in turn, eases the burden on these teams. If we take a look at social engineering attacks such as spear phishing and business email compromise (BEC), they're extremely hard to detect.
