In fact, large corporations such as Airbnb, PayPal and Spotify, recently revealed that they have willingly spent over £38M on ethical hackers to tighten their cyber defences and avoid crippling data breaches. Ethical hackers can play a fundamental role in helping security teams consider every single possible attack vector when protecting applications. Whilst security architects have a wealth of knowledge on industry best practise, they often lack first-hand experience of how attackers perform reconnaissance, chain together multiple attacks or gain access to corporate networks. Equipped with – one hopes – all the skills and cunning of their adversaries, the ethical hacker is legally permitted to exploit security networks and improve systems by fixing vulnerabilities found during the testing. While it may sound counter-intuitive to make use of hackers to help plan and test our cyber defences, the one thing they have in abundance is valuable, hands-on experience.According to the 2019 Hacker Report, the white hat hacker community has doubled year over year. At the end of the day, a hacker is a hacker.
