An engineering firm, not a reseller
Intrust Security is an independent security engineering firm based in Chattanooga, Tennessee, serving clients across the United States. We design, build and operate detection and response programs on Palo Alto Networks Cortex XSIAM, CrowdStrike Falcon and Tines, and we provide vendor-neutral detection engineering and advisory for teams that want senior direction without a full-time hire.
Our engineers bring 15+ years of experience building and running security programs in enterprise and Fortune 500 environments. That experience shows up in the details: parsers that survive upstream changes, detections with documented rationale, automations with error paths, and handover documentation written for the people who will own the work next.
What we believe
- Engineering beats tooling sprawl. The platform you already run, configured well, outperforms the next purchase.
- Detection coverage is a measurable thing. If it is not mapped, tested and reported, it is a hope.
- Automation should remove toil, never judgment. Humans stay in the loop where the decision matters.
- You own everything we build. Work happens in your tenants and your repositories, with documentation to match.
How we engage
Three shapes cover most needs: project engagements with a defined scope and deliverables, retained engineering for a fixed number of hours or days per month, and fractional leadership for teams that need a senior security engineer in the room without a full-time seat. Every engagement starts with a written scope and ends with evidence and a handover.
We work remotely with clients across the United States and on site when the work calls for it.
