Jelle D

I help companies stay in control of cybersecurity and compliance. I run Coding Mammoth, where I work as a fractional CISO for SaaS companies and growing organizations. I support teams in understanding their security risks, setting clear priorities, and making practical decisions that fit their business and maturity level. My work typically includes cybersecurity leadership, ISO 27001 implementation and maintenance, internal audits, and translating regulatory or customer requirements into workable processes. The focus is always on control, ownership, and pragmatism, without unnecessary overhead. In parallel, I build and operate my own SaaS products, including Semonto. Running software in production keeps my advisory work grounded in real operational, security, and compliance challenges. I help organizations move from uncertainty to control.
