You are a strategy lead in the Corporate Security & Risk Office at NorthBridge Financial Technologies (NFT), a publicly listed fintech infrastructure provider that powers card issuing, ACH, and real-time payouts for mid-market banks and large marketplaces. NFT processes roughly $420B in annual payment volume, generates $3.6B in revenue (FY2025), and operates under a mature security program with SOC 2 Type II, ISO 27001, and strong audit relationships.
NFT has just acquired BrightWave Payments (BWP), a fast-growing payments orchestration platform used by SaaS companies and subscription merchants to route transactions across multiple PSPs. BWP brings $210M ARR growing at 28% YoY, but it has historically operated like a startup: a lean IT team, minimal formal governance, and “good enough” security controls. The acquisition thesis depends on cross-selling BWP into NFT’s bank clients and bundling BWP’s orchestration into NFT’s enterprise contracts.
Within 90 days, NFT must decide which security control investments to prioritize at BWP to (1) reduce breach risk and operational disruption, (2) unlock enterprise revenue synergies, and (3) satisfy regulatory and customer due diligence requirements.
Two catalysts make this urgent:
Your CISO asks a pointed question to focus the organization: “If we could only implement one CIS Critical Security Control first at BrightWave, which one gives the highest ROI—and why?”
BWP has ~520 employees (200 engineers), operates a hybrid cloud stack (AWS + some on-prem), and handles sensitive payment data but relies on tokenization and third-party vaulting for PAN.
NFT’s integration office estimates that security uplift at BWP impacts both downside risk and upside revenue.
Commercial pipeline (next 12 months):
| Segment | # Deals in pipeline | Avg ARR per deal | Win probability today | Win probability if baseline controls met | Notes |
|---|---|---|---|---|---|
| Tier-1 Banks | 8 | $4.5M | 20% | 35% | Security due diligence is gating factor |
| Marketplaces | 18 | $1.2M | 25% | 30% | Security important but not sole driver |
| SaaS/Subscription | 40 | $180K | 30% | 32% | Mostly product-led; security questionnaires lighter |
Risk model (internal, directional):
NFT’s security architects narrowed the “first control” decision to four candidates that are feasible within 90 days. Assume you can pick one to prioritize as the flagship initiative (others may follow later).
| Candidate CIS Control (v8) | What it entails at BWP (scope) | 90-day cost estimate | Primary benefit hypothesis |
|---|---|---|---|
| CIS 1: Inventory and Control of Enterprise Assets | Build authoritative asset inventory across endpoints, servers, cloud accounts; ownership tagging; decommission unknown assets | $450K | Reduces unknown exposure; enables other controls |
| CIS 4: Secure Configuration of Enterprise Assets and Software | Baseline hardening for endpoints + cloud (CIS benchmarks), config drift detection, golden images | $900K | Prevents common misconfig exploits; reduces attack surface |
| CIS 5: Account Management | Enforce MFA everywhere, remove shared accounts, privileged access workflows, joiner/mover/leaver automation | $650K | Reduces credential-based compromise; improves audit posture |
| CIS 8: Audit Log Management | Centralize logs (cloud + identity + critical apps), retention, alerting on key detections | $800K | Improves detection/response; supports forensics and compliance |
As the strategy lead, prepare a recommendation for the CISO and integration steering committee:
You may ask clarifying questions, but assume the above is the data available in the interview.
