- RMF analysts & compliance documentation specialists
- Cloud security engineers (AWS, Azure, GCP)
- SOAR engineers & automation developers
- Detection content developers
Simple, Transparent Process
No bloated SOWs. No surprise invoices. Three clear phases from kickoff to handoff.
Discovery & Scoping
We start with a focused conversation to understand your environment, security gaps, compliance requirements, and team capacity. From there, we define a clear scope, timeline, and deliverables — no ambiguity.
Execution & Delivery
Our engineers embed with your team or work independently to deliver results. Whether it's building detections, automating workflows, or completing compliance documentation — we ship production-ready work on schedule.
Handoff & Enablement
Every engagement ends with a clean handoff: documentation, knowledge transfer, and training so your team can maintain and build on what we've delivered. We don't create dependency — we create capability.
Challenges We Solve
We work with teams facing real operational pressure — not hypothetical risks.
Flexible engineering without full-time hires
Scale your security engineering capacity up or down as projects demand — without the overhead of permanent headcount.
Rapid detection & automation
Get detection rules, SIEM content, and automated workflows deployed fast — by engineers who've done it across dozens of environments.
Temporary capacity for understaffed teams
Bridge staffing gaps with experienced security engineers who can hit the ground running and integrate with your existing workflows.
IR automation & SOAR
Build and operationalize SOAR playbooks that actually reduce response times — from triage to containment to reporting.
Compliance & documentation
Produce audit-ready RMF packages, security documentation, and assessment support that satisfies federal and regulatory requirements.
Security architecture reviews
Get an independent, expert review of your cloud and on-prem security architecture with actionable recommendations — not a 200-page report that sits on a shelf.
What We've Delivered
Representative engagements that reflect the kind of work we do.
Reducing alert noise & improving visibility
Helped a mid-size federal agency reduce false-positive alerts by 60% through tuned detection logic, custom Splunk correlation rules, and a prioritized alerting framework — all delivered in a 6-week engagement.
