Building a Defensible Security Posture and Payment Compliance for a Trading Firm

A Chicago-based trading firm that gives retail traders a path to funded futures accounts had never formalized its security program beyond meeting basic obligations. As the business scaled, an undocumented security posture and looming payment card compliance requirements created growing exposure — the kind of gap regulators and payment processors don't overlook indefinitely. Redapt built the firm a documented security baseline, a prioritized remediation roadmap, and a completed PCI DSS SAQ A self-assessment, replacing ad hoc coverage with a defensible, board-ready posture.

Turning Challenges Into Opportunities

From Undocumented Risk to a Defensible Security Program

The firm's security program had grown organically alongside the business — enough to operate, but not enough to withstand scrutiny. As transaction volume increased, so did exposure to payment card industry requirements that the organization had not yet formally addressed, leaving a widening gap between what the business needed and what it could prove.

For firms handling payment data at scale, an informalized security program isn't a documentation gap — it's an unpriced liability. The organizations that close that gap before an auditor or processor finds it are the ones that keep growing without a compliance event interrupting the business.

The Problem

The trading firm's security controls had never been assessed against a defined framework, and payment card industry requirements loomed as transaction volume grew. Leadership could not point to a documented baseline, a prioritized remediation plan, or evidence that the organization's security posture would withstand a formal audit. Closing that gap required an outside, structured assessment — not another internal checklist.

The Solution

Redapt's Security Practice conducted a guided Readiness Assessment against the firm's chosen security framework, combining document review, control testing, and live stakeholder interviews to produce a scored snapshot of the program's maturity. From that baseline, Redapt built a prioritized Remediation Roadmap — sequencing fixes by risk, cost, and effort — then brought in a PCI-specialist delivery partner to guide the firm through its PCI DSS SAQ A self-assessment.

The Outcome

The organization now holds a documented security baseline, a scored assessment it can defend to leadership or an auditor, and a remediation roadmap sequenced by risk and cost. Its PCI DSS SAQ A self-assessment is complete and evidence-backed, closing a compliance gap that had grown alongside the business. Security decisions that were once reactive now run against a defined, prioritized plan.
