Introducing Simon

Simon is the co-founder of Certo and a cybersecurity practitioner with over 15 years of hands-on experience in the field. Holding an honours degree in Computer Forensics, Simon's technical foundation is both academic and deeply practical — he personally wrote the first versions of Certo's apps, building the company's core products from the ground up.

Before co-founding Certo, Simon worked as an independent cybersecurity consultant, advising companies and law firms during active cyber incidents. His casework spanned hacking investigations, fraud, intellectual property theft, and eDisclosure — experience that gave him a frontline understanding of the real-world consequences of digital vulnerabilities.

That consulting background directly informs everything Simon writes and builds. Rather than approaching cybersecurity from a theoretical standpoint, his insights are drawn from years of diagnosing and resolving actual incidents for real clients. At Certo, he has translated that expertise into software used by millions of people to protect their devices and personal data.

Simon holds an honours degree in Computer Forensics, which underpins his methodical approach to both software development and cybersecurity education. Outside of work, he is an amateur astrophotographer, taking full advantage of the rare clear nights the UK has to offer.
