Chris Vaughan

Chris Vaughan is a Solution Engineer at Sublime Security, specialising in email threat detection and the ever-evolving tactics attackers use to compromise organisations. With over 15 years of experience in enterprise cybersecurity, spanning endpoint security, IT forensics, and now email. Chris works day-to-day with security teams across FTSE 100 and Fortune 500 organisations to help them understand and defend against the modern threat landscape. Chris has a deep interest in phishing tradecraft and social engineering, particularly how attackers are shifting toward precision, trust exploitation, and evasion stacking. He's closely tracked trends like the dramatic surge in ICS, QR code phishing, the rise of AI-generated attacks, rapport-building phishing, and thread hijacking; where attackers insert themselves into legitimate email threads to fabricate trust and context. These aren't abstract threats: they're the campaigns Chris helps organisations detect and respond to every week. A recog
