Penetration Testing Services in Chicago, IL
Chicago's pentest demand profile is unusually rich: the trading and proprietary-finance ecosystem around the CBOT and CME, a massive logistics and rail-hub footprint, and a deep manufacturing base in the collar counties. Trading-firm pentest buyers in particular care about one thing that generalist vendors miss — does the tester understand quant tooling and broker APIs, or are they only going to find the obvious findings?
Why Chicago buyers choose QUANT LAB USA
QUANT LAB USA has in-house algorithmic trading bot development and broker-integration capability. That informs how we attack trading-firm infrastructure — credential exposure on broker API endpoints, FIX session abuse, internal lateral movement to position data, and the integration seams between research and execution. For non-trading Chicago clients we run the same web app and AD engagements we run elsewhere.
Scope & coverage
Four engagement types cover most of what Chicago clients ask for. Web application pentests — OWASP Top 10, business logic, authentication, authorization, and API security across REST and GraphQL. Internal network and Active Directory engagements — Kerberoasting, AS-REP roasting, lateral movement, ADCS abuse, and credential dumping from an assumed-breach starting position. External perimeter assessments — attack surface mapping, exposed services, and credential exposure. Wireless engagements — corporate Wi-Fi, guest network isolation, and BYOD segmentation.
Every technique used is mapped to a MITRE ATT&CK ID so your detection team — in-house or MSSP — can see what your defenses caught and what they missed. Reports include the executive summary, full technical narrative, evidence chain, and a remediation roadmap prioritized by exploitability rather than CVSS alone.
The local angle
For Chicago trading firms, scope typically combines an external perimeter and web app test against client-facing surfaces with an internal AD review focused on lateral movement paths to trading systems and PnL data.

FAQ — Chicago engagements
Do you understand trading firm and broker-API security?
Yes. We do in-house algorithmic trading bot development and broker integration — IBKR, Alpaca, TopstepX, Tradier, and others. That informs how we test trading firms from the inside, not just from the outside.
Can you support a SOX-driven internal audit cycle?
Yes — reports are formatted to drop into SOX audit binders, with the control-mapping appendix Chicago SOX-bound clients ask for. We have shipped pentest output into completed SOX cycles.
Do you fly in for kickoffs?
For engagements that warrant it, yes. Discovery and reporting are remote-default; on-site is available for trading floor walkthroughs and physical red team scoping.
