(About)
Security engineers who build with AI.
MarkCyber is a Canadian cybersecurity firm that helps enterprises defend against modern threats and adopt AI securely. We engineer detection, protect cloud and identity, and deploy and govern AI systems, so organisations can move faster without taking on new risk.
What we hold to
- (01)Detection is engineering.
Rules map to how attackers behave, ship with tests, and are measured like any other product.
- (02)Every AI system has an owner.
A named person, a written policy and an audit trail, before it touches real data.
- (03)People approve what changes state.
Agents investigate and draft. Anything that changes an account, a host or a message waits for a person.
- (04)Data stays where it belongs.
Private models when the data cannot leave, and minimised, tokenised data when it must.
- (05)We hand it over.
Everything we build arrives as code with documentation. You are never dependent on us to keep it running.
- (06)We publish what we learn.
Research briefs and detection content are part of the job, not marketing.
How an engagement runs
- 01Briefing
Thirty minutes with an engineer on one question that matters to you. You leave with a clear answer.
- 02Scope
A short, fixed scope tied to a problem and a number, with the guardrails agreed up front.
- 03Build
We work in your tools and your cloud, alongside your team, with weekly evidence of progress.
- 04Hand over
Code, documentation and a walkthrough. Then we measure the number we agreed on.
Where we are
Toronto, Ontario. We work across Canada and North America, remote-first, on site when the work needs it.
Start with one question.
Thirty minutes with an engineer. You leave with a clear answer, not a pitch.
