About DevSec Security

Local team, strong values, and a hands-on approach to looking after buildings.

DevSec

We’re a family-run security company based in Brisbane. We show up, do the job properly, and look after the people and places we’re responsible for.

About us

The DevSec story

We started DevSec because we care about how buildings feel and how people are treated. Good security isn’t just about presence — it’s about attitude, consistency, and doing the small things well. From the beginning, our approach has been to pick the right people, train them properly, and give them the support they need to do their job with confidence and pride.

Being family-run keeps us grounded. We stay close to the work, we know our clients by name, and we check in to make sure things are running the way they should. We’ve grown through word of mouth and steady results.

We’re here to deliver work that’s reliable, respectful, and easy to deal with. Every day, every site.

Our beliefs

What we believe in

At the end of the day, this work is about people. The buildings, the tenants, the clients, the team. We look after each other, and we look after the places we’re responsible for.

We keep things simple:

  • Be decent. Treat people with respect.
  • Take pride in the job. Leave things better than you found them.
  • Say what you mean. Keep your word.
  • Back your team. No one does this work alone.
  • Keep learning. Pay attention, grow bit by bit.

FAQs

Frequently asked questions

Who will I be dealing with day-to-day?

You’ll deal directly with our management team and the people on your site. No layers, no call centres.

Do you offer long-term contracts?

We can, but we don’t lock people in. Most clients stay because the service is consistent and easy to work with.

How do you make sure standards stay high?

Regular check-ins, clear reporting, and being present on site. We stay involved — we don’t hand things off and disappear.

Can you handle multiple buildings or portfolios?

Yes. We work with single sites and multi-building portfolios across Brisbane and South East Queensland.
