We’re an Australian owned security company based in Brisbane. We show up, do the job properly, and look after the people and places we’re responsible for.
The DevSec story
DevSec was founded on a simple belief - the way a workplace feels matters, and the way people are treated matters even more.
Effective security is not just about presence; it is built on professionalism, consistency and attention to detail. From day one, our focus has been to select the right people, invest in structured training and provide the leadership and systems they need to perform with confidence and pride.
As a founder-led business, our leadership team remains actively involved in operations, client engagement and service performance. This hands-on approach ensures our standards are not just set - they are consistently delivered across every site.
We are also committed to creating genuine career pathways within the security and concierge industry, with a strong focus on developing women into operational and leadership roles. This strengthens our teams, improves workplace culture and reflects the environments we operate within.
Our growth has been driven by long-term partnerships, measurable outcomes and a reputation for being reliable, accountable and easy to work with.
Every day. Every site. One consistent standard.

What we believe in
Our people come first. Our service is built on people, professionalism and consistent standards. We take ownership of the workplaces we support and deliver our services with respect, accountability and attention to detail.
Our approach is simple:
Lead with respect. Be professional, stay calm and treat everyone well.
Take pride in standards. Do the small things properly and leave every site better than we found it.
Communicate clearly. Say what you mean, follow through and keep your word.
Back the team. We operate as one - shared accountability, no silos.
Keep improving. Stay alert, keep learning and raise the standard every day.
How we work
We choose staff who know how to talk to people, not just watch them. Safety and service go hand in hand.
