You talk to engineers, not account managers
Your first call is with the people who will actually do the work. No sales layer, and no quiet handoff to juniors once the contract is signed.
Safety-critical background
The firm was built on twenty-five years across aerospace certification and financial data platforms — environments where "it seems to work" is not an acceptable answer.
Security runs through everything
The AI work, the mobile work and the infrastructure work are all done alongside the people who handle the incidents. That changes how things get built.
Local, and remote-capable
On the ground across Montreal and the South Shore, and working remotely with clients across Canada and the US.
Serving Montreal, the South Shore and beyond
On site across the greater Montreal region, and remote for clients everywhere else.

Frequently asked questions
What does Digital Security Consulting actually do?
We are an independent engineering firm of more than twenty engineers, covering cybersecurity and ransomware recovery, IT infrastructure and backup, AI integration, software and product engineering, mobile app development, wireless and network security, WordPress development, engineering and certification services, and crypto and blockchain work. The common thread is security-first engineering delivered by senior people.
Where are you located and who do you serve?
We are based in Candiac on the South Shore of Montreal, and serve businesses across Candiac, La Prairie, Brossard, Longueuil, Saint-Lambert, Boucherville, Montreal, Laval and the wider Quebec region, plus remote clients across Canada and the United States.
Do you work with small businesses, or only large companies?
Both. A significant share of our work is with small and mid-sized businesses who need senior engineering judgement without hiring a full-time specialist. We scope work to your actual risk and budget rather than selling a fixed package.
Do you offer emergency incident response?
Yes. For active incidents such as ransomware, a breach or a compromised site, write URGENT in your message and we prioritise it ahead of scheduled work, aiming to begin remote triage the same business day.
Do you work in French and English?
Yes. All services are delivered in both French and English, including written documentation and reports.
Tell us what is breaking — or what you are trying to build.
You get a senior engineer on the first call, not a salesperson. If we are not the right fit, we will say so and point you somewhere better.
Active incident? Write “URGENT” in your message and we prioritise it.
