moves through.

Adversim delivers senior-led penetration testing, framework-aligned assessments, and strategic advisory for banks, credit unions, fintech platforms, RIAs, broker-dealers, and payment processors. Financial services is one of the most heavily regulated, most heavily targeted, and most rapidly evolving cybersecurity environments in the United States — and the consulting industry serving it is overdue for an alternative.

// Why Financial Services Is Different

Financial cyber risk runs on regulated rails.

Financial services cybersecurity sits at the intersection of consumer protection law, prudential regulation, payment industry standards, and increasingly sector-specific cyber rules. A community bank in the Midwest, a Series-C fintech in San Francisco, an RIA managing $500M in client assets, and a payment processor handling card-not-present transactions all operate under fundamentally different regulators — but the underlying threat model is largely the same: direct financial loss, regulatory enforcement, customer trust damage, and the operational impact of an incident that hits the wrong system at the wrong time.

Regulators have responded with increasingly prescriptive cybersecurity expectations. FFIEC examiners now expect annual penetration testing and continuous control monitoring. The New York Department of Financial Services pioneered cybersecurity-specific regulation with Part 500, and many states have followed with similar rules. The SEC has expanded cyber disclosure obligations for public companies and registered investment advisers. Federal banking regulators expect every supervised institution to have a documented cybersecurity program proportionate to its risk profile.

Adversim works across this regulatory landscape with senior practitioners who understand the difference between FFIEC and NYDFS, between PCI-DSS and SOX, between an RIA examination and a broker-dealer audit. We deliver penetration testing calibrated to the threat actors actually targeting financial services, risk assessments that satisfy examiner expectations, and strategic advisory that recognizes the unique pressures financial services security teams operate under.

// Financial Services Threat Landscape

Six threats defining
financial services cybersecurity
right now.

Observed attacker behavior, not theoretical risk.

// THREAT 01 — BEC & WIRE FRAUD

Business Email Compromise

Wire fraud through compromised email accounts remains the highest-dollar-loss cyber threat for financial institutions. FBI IC3 reports billions in annual losses, with community banks, RIAs, and fintech platforms repeatedly targeted. Attackers exploit identity, process, and verification gaps — not just technical controls.

// THREAT 02 — ATO & FRAUD

Account Takeover & Credential Stuffing

Stolen credentials from breach corpuses are tested at scale against bank and fintech login portals. Account takeover leads to fraudulent transfers, identity theft, and downstream losses. MFA implementation quality varies enormously across the sector and is repeatedly identified as the difference between successful and failed campaigns.

// THREAT 03 — RANSOMWARE

Targeted Financial Ransomware

Ransomware operators target financial services for the operational leverage and reputational damage their incidents create. Multi-day outages of core banking, lending, or payment platforms create both direct losses and regulatory examination scrutiny that follows for years.

// THREAT 04 — API ABUSE

API & Open Banking Abuse

Financial APIs — open banking interfaces, payment APIs, fintech-bank integrations — present an attack surface that didn’t exist a decade ago. OWASP API Security Top 10 vulnerabilities (BOLA, broken authentication, excessive data exposure) are routinely identified in fintech testing.

// THREAT 05 — INSIDER

Insider Threat & Privileged Abuse

Financial services workforce access to high-value data and transaction systems makes insider threat a persistent enforcement category. Detection requires behavioral analytics, separation of duties, and program-level controls most institutions are still maturing.

// THREAT 06 — SUPPLY CHAIN

Core Provider & Fintech Dependency

Community banks and credit unions are increasingly dependent on core processors, fintech overlays, and managed service providers. Supply chain compromises hit downstream institutions hard, with limited control over upstream vendor security.

// FFIEC & NYDFS Deep Dive

The cybersecurity rules examiners care about.

Financial services cybersecurity is shaped by two regulatory frameworks that together define what examiners expect: the FFIEC Cybersecurity Assessment Tool (and its successor frameworks for banks and credit unions) and the NYDFS Cybersecurity Regulation 23 NYCRR Part 500, which has become a de facto national standard despite being a state regulation.

FFIEC expectations for supervised institutions

The FFIEC framework is risk-based and proportionate — examiners don’t expect a community bank to operate like a money-center bank, but they do expect every institution to have a cybersecurity program that matches its inherent risk. Annual penetration testing is a baseline expectation for most institutions, and many examiners now expect documented continuous control monitoring as well.

Our FFIEC-aligned engagements include external and internal penetration testing scoped for banking environments, cybersecurity control assessments mapped to the FFIEC framework, and the documentation examiners actually want to see — not the binder-thick template assessments that don’t answer the question of whether controls actually work.

NYDFS Part 500 — the de facto national standard

Even institutions that aren’t directly supervised by NYDFS often align to Part 500 because it’s become the most prescriptive and comprehensive state cybersecurity regulation. Part 500 amendments effective 2023-2024 added explicit requirements around governance, CISO reporting to the board, vulnerability management, asset inventory, encryption, multi-factor authentication, and a 36-hour cybersecurity event reporting window that’s become the model for similar state and federal rules.

We help institutions align to Part 500 whether or not they’re directly regulated by NYDFS, because the framework increasingly represents what examiners across the country expect.

// Financial Services Cybersecurity FAQ

Straight answers
for financial services.

FFIEC doesn’t prescribe a single cybersecurity framework, but the FFIEC IT Examination Handbook and the FFIEC Cybersecurity Assessment Tool (CAT) establish baseline expectations. Most examiners expect documented annual penetration testing, regular vulnerability assessments, formal risk assessments tied to your institution’s inherent risk profile, defined incident response and recovery plans, and continuous monitoring of cybersecurity controls. Examination findings are increasingly explicit about expectations around governance, asset inventory, and vendor risk management.
Not directly, but Part 500 has become the de facto national standard for financial services cybersecurity regulation. Many institutions that aren’t NYDFS-supervised align to Part 500 anyway because it represents what examiners across the country are increasingly expecting. The 2023-2024 Part 500 amendments are particularly comprehensive — covering CISO reporting, board governance, encryption, MFA, asset inventory, vulnerability management, and the 36-hour reporting window.
Most financial services penetration testing engagements fall between $20,000 and $75,000. A focused external test for a community bank or small RIA runs $20,000-$30,000. Comprehensive engagements covering external, internal, online banking, and mobile applications for mid-size institutions typically run $40,000-$75,000. Fintech platforms with significant API attack surface scale higher. All pricing is fixed-fee.
Yes. Our team has direct experience testing against and around major core banking platforms (FIS, Fiserv, Jack Henry), payment processors, open banking providers, and the fintech overlays that increasingly sit on top of bank charters. We understand the shared-responsibility constructs that apply when your environment integrates with vendor-managed systems.
Yes. Many of our vCISO and retained clients engage us specifically to support FFIEC, NYDFS, or state regulatory examinations — preparing documentation, responding to examiner requests, and providing senior-level explanations of our prior testing and assessment work. Examiners generally view third-party penetration testing and risk assessment work favorably when the work product is substantive and the firm performing it is credible.
We perform PCI-DSS readiness work — scope definition, segmentation validation, gap analysis, and remediation guidance — that dramatically reduces the cost and timeline of an actual QSA engagement. We don’t issue Reports on Compliance ourselves (that requires QSA credential), but we make sure your QSA’s job is easier and that you don’t fail control validations you could have caught earlier.
Cyber insurance underwriting for financial services has become substantially more rigorous. Carriers increasingly require evidence of recent penetration testing, MFA enforcement, EDR deployment, backup integrity validation, and incident response readiness. We perform the underlying work and produce reports that satisfy underwriter requirements, frequently resulting in better terms or premium reductions.
No. Adversim is a proactive cybersecurity practice. We do not perform active incident response, live breach containment, or digital forensics. We focus on readiness — penetration testing, risk assessments, tabletops, ransomware readiness, and the program-level work that prepares financial institutions for incidents before they occur. We can help you identify and onboard a qualified DFIR partner in advance.
