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.
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.
Observed attacker behavior, not theoretical risk.
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.
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.
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.
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.
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.
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.
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.
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.
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.
We work across the relevant regulatory landscape for the industry.
Most engagements in this vertical start with one of these patterns.
External and internal testing scoped to banking, fintech, and payment environments: core banking application exposure, online and mobile banking, payment systems, API security, and the integration points where most fintech vulnerabilities actually live.
GLBA Safeguards Rule risk assessments, FFIEC-aligned cybersecurity control assessments, NYDFS Part 500 gap analysis, PCI-DSS readiness for payment environments, and SOC 2 readiness for fintech vendors selling into bank channels.
Fractional CISO advisory for community banks, credit unions, RIAs, and fintech companies. NYDFS-aligned CISO reporting, board cybersecurity reporting, examiner engagement support, ransomware readiness, and BEC tabletop exercises.
