William Mireles is an Enterprise Sales Engineer at Sublime Security, an AI-native email security platform challenging the way organisations think about defending their inboxes. He joined as the company's first EMEA hire, working day-to-day with enterprise clients on the front lines of a threat landscape that's evolving faster than most legacy tools can keep up with. Over the past five years, William has accumulated broad experience across B2B SaaS, spanning industries including healthcare, hospitality, ad-tech and now cybersecurity. This cross-industry background has given him a grounded understanding of how organisations of varying size and maturity approach technology adoption - and the operational complexities that so often accompany it. Today, his work centres on helping enterprise clients bridge the gap between legacy security infrastructure and the demands of a modern threat environment, where attacks are increasingly automated, targeted and difficult to detect. It is a challenge that sits at the core of Sublime Security's mission, and one that William brings both technical depth and commercial perspective to.
