How did Sentrium come to be?
FUELING CURIOSITY.
PROTECTING YOUR FUTURE.
Back in 2018, we saw a gap forming in the cyber security industry in the UK. Organisations were increasingly left without a partner who could offer consistent quality, clarity, and flexibility in penetration testing services. In response, Adam and Tim saw the space for a consultancy that understood those pressures and worked differently.
We started Sentrium with a clear focus: to use our expertise to deliver penetration testing and security advice that genuinely helps organisations. Since then, we’ve grown into a team that continues to strengthen year on year.
Clients choose us because we offer a balance of cost, quality and flexibility that’s hard to find elsewhere, and because we treat their challenges with the same care and curiosity we bring to our technical work.

I’ve worked with Sentrium Security since the beginning, and it’s been an absolute pleasure working with the team over the past six years. A lot has changed during that time, but what’s stayed consistent is the drive to be the best, which shows in everything the company does.
