About Net Sec Group

A NOTE FROM DANIEL

Director of Net Sec Group

After 12 years in His Majesty's Royal Marines, I transitioned into cybersecurity with a mission to apply strategic discipline to a digital threat landscape. That mindset continues to shape our work at Net Sec Group — where customer focus, agility, and integrity define everything we do.

Working as Part of Your Team

Whether supporting you for a short-term project or across the year, we operate as an embedded extension of your team. Our full-stack security services are tailored to your needs and designed to secure your people, platforms, and data — not just your technology.

Built on Relationships, Not Sales Targets

We understand that delays happen, so we prioritise flexibility and collaboration over penalties. Our team values autonomy and takes pride in delivering high-quality work — this dedication drives our referral-based growth, not aggressive sales tactics.

Accessible and Efficient by Design

Our lean operating model allows us to deliver expert services without the overheads often seen in the industry — passing those savings directly to you.

Giving Back with Purpose

We dedicate time to supporting charities with pro bono cybersecurity services each year, ensuring our skills benefit communities beyond commercial spaces.

Here for What Matters

Our mission isn't about personal accolades. It's about protecting your organisation with clarity, discipline, and a tailored approach delivered by experienced professionals, including CREST-registered testers.
