Why Cybercriminals Target Financial Institutions
Financial services firms hold the most valuable data on earth — account credentials, Social Security numbers, transaction histories, and direct access to money movement systems. This makes every bank, credit union, and investment firm a high-priority target.
Ransomware Targeting Core Banking
Ransomware groups specifically target financial institutions because downtime is catastrophic. When account holders cannot access funds, regulatory scrutiny intensifies immediately. The average ransom demand for financial firms exceeded $1.3 million in 2024, but the operational disruption costs are often ten times higher. Our endpoint detection and response solutions stop ransomware before encryption begins.
Business Email Compromise & Wire Fraud
BEC attacks cost financial institutions billions annually. Attackers impersonate executives, clients, or vendors to redirect wire transfers, manipulate ACH payments, or authorize fraudulent transactions. A single compromised email account at a bank can lead to seven-figure losses within hours. Our email security and phishing protection services eliminate these attack vectors.
Regulatory Fines & Enforcement Actions
The SEC, OCC, FDIC, and state regulators are imposing record cybersecurity fines. The SEC’s 2023 cybersecurity rules require public companies to disclose material incidents within four business days. Non-compliance can result in fines exceeding $10 million, consent orders, and personal liability for officers. Our compliance consulting ensures you meet every requirement.
Third-Party & Vendor Risk
Financial institutions rely on dozens of technology vendors — core banking platforms, payment processors, fintech APIs, and cloud services. Each vendor connection expands your attack surface. The OCC’s third-party risk management guidance (OCC Bulletin 2023-17) requires rigorous vendor due diligence and ongoing monitoring. Our supply chain security program addresses this comprehensively.
IT & Cybersecurity Services for Financial Institutions
Every service we deliver to financial clients is engineered with regulatory compliance, audit readiness, and data protection at the core — not bolted on as an afterthought.
24/7 Security Operations Center (SOC) for Banking
Financial institutions cannot afford blind spots. Our SOC-as-a-Service provides continuous monitoring of your entire banking infrastructure — core banking systems, ATM networks, online banking platforms, wire transfer systems, and employee endpoints.
What Our Financial SOC Monitors
- Transaction anomalies: Unusual wire transfer patterns, ACH batch anomalies, and after-hours transaction activity that could indicate fraud or account compromise
- Authentication events: Failed login attempts, impossible travel scenarios, credential stuffing attacks against customer portals, and privilege escalation attempts
- Network lateral movement: Attackers who breach one system attempting to reach core banking, SWIFT terminals, or treasury management platforms
- Compliance-critical events: Changes to access controls, audit log tampering attempts, and unauthorized access to regulated data stores
Every alert is triaged by analysts who understand financial regulatory requirements. When we escalate an incident, we include the compliance implications alongside the technical details.
Managed IT Infrastructure for Banks & Credit Unions
Running a bank’s IT infrastructure requires more than generic managed services. Your core banking platform, teller systems, ATM network, customer-facing portals, and back-office systems must operate at near-zero downtime while maintaining strict security boundaries.
Financial IT Management Includes
- Core banking system administration: Patching, performance optimization, and availability monitoring for platforms like Jack Henry, FIS, Fiserv, and Q2
- Branch network management: Secure connectivity between headquarters, branch offices, and remote employees with encrypted VPN tunnels and network segmentation
- Endpoint fleet management: Standardized, hardened configurations for teller workstations, loan officer laptops, and executive devices — all centrally managed and monitored
- Cloud infrastructure: Secure migration and management of workloads on Azure, AWS, or private cloud environments with cloud security posture management
- Backup and disaster recovery: RPO/RTO targets that satisfy regulatory expectations and FFIEC guidance, with tested disaster recovery runbooks
Fraud Prevention & Transaction Security
Fraud detection is no longer optional — it is a regulatory and competitive necessity. Our fraud prevention services combine technology controls with process improvements to dramatically reduce loss exposure.
Multi-Layered Fraud Defense
- Email authentication (DMARC/DKIM/SPF): Prevents domain spoofing that enables BEC attacks targeting wire transfer authorization chains
- Multi-factor authentication: Enforced across all systems with elevated access — including dual authorization for wire transfers and ACH batch releases. We deploy multi-factor authentication that satisfies FFIEC guidance
- Privileged access management: Time-limited, audited access to core banking administration, treasury systems, and database environments
- Security awareness training: Financial-services-specific phishing simulations and training that teach employees to recognize BEC, vishing, and social engineering attacks targeting financial workflows
Penetration Testing & Vulnerability Assessment
Regulatory examiners expect evidence that your institution regularly tests its defenses. Our penetration testing services are designed specifically for financial institutions and include testing scenarios that regulators look for.
Financial Penetration Testing Scope
- Online banking applications: Testing for OWASP Top 10 vulnerabilities, session management flaws, authentication bypass, and API security weaknesses
- Internal network: Simulated attacks from a compromised workstation to determine how far an attacker could move laterally toward core banking systems
- Social engineering: Phishing campaigns, phone pretexting, and physical security assessments targeting branch offices and data centers
- ATM and payment systems: Testing the security of ATM networks, point-of-sale integrations, and card processing environments
- Wireless networks: Ensuring branch and headquarters Wi-Fi networks cannot be used to access production banking systems
Every test produces examiner-ready reports with risk ratings, remediation priorities, and retesting verification documentation.
Secure Trading & Wealth Management Platforms
Investment firms, RIAs, and broker-dealers face unique security challenges centered around trading platform integrity, client portfolio data protection, and SEC/FINRA cybersecurity requirements.
Investment Firm Security Services
- Trading platform security: Hardened configurations, encrypted communications, and access controls for platforms including Bloomberg Terminal, Charles River, and proprietary systems
- Client portal protection: Secure web application hosting with DDoS protection, WAF rules, and real-time threat monitoring for client-facing investment portals
- Communication archiving: Secure email and messaging archival that satisfies SEC Rule 17a-4 and FINRA supervisory requirements
- Data loss prevention: Controls preventing unauthorized transmission of material non-public information (MNPI) or personally identifiable client data
Financial Regulatory Compliance Support
Financial institutions operate under the most complex compliance landscape in any industry. We help you navigate overlapping federal and state requirements while building security programs that satisfy multiple frameworks simultaneously.
SOX (Sarbanes-Oxley)
IT general controls (ITGCs) for financial reporting systems. Change management, access controls, and audit trails that satisfy Section 404 testing. We document every control so your external auditors can test efficiently, reducing audit costs and findings.
GLBA (Gramm-Leach-Bliley)
Implementation of the Safeguards Rule requirements including risk assessment, information security program development, encryption standards, and employee training. We ensure customer financial information is protected throughout its lifecycle — collection, storage, transmission, and disposal.
PCI DSS
Cardholder data environment scoping, network segmentation, vulnerability scanning, and PCI DSS compliance validation. Whether you process ten transactions or ten million, we right-size your PCI program to minimize scope while maintaining full compliance.
SEC Cybersecurity Rules
The 2023 SEC cybersecurity disclosure rules require registrants to disclose material cybersecurity incidents within four business days and describe cybersecurity risk management, strategy, and governance. We build the incident detection and classification processes that enable timely, accurate disclosure.
FFIEC Guidance
FFIEC IT examination handbooks cover information security, business continuity, outsourcing technology, and development and acquisition. Our programs align with FFIEC expectations so your institution is examination-ready at all times, not just during audit season.
BSA/AML & FINRA
Technology controls supporting Bank Secrecy Act compliance including suspicious activity monitoring, CTR automation, and CDD/EDD processes. For broker-dealers, we implement the technology controls that satisfy FINRA’s cybersecurity guidance and BCP requirements.
How We Protect Financial Institutions
Scenario: Community Bank Faces Regulatory Examination
A 12-branch community bank in North Carolina received notice of an upcoming FDIC information technology examination. Their internal IT team had handled day-to-day operations competently, but they had no formal information security program, no written incident response plan, and their last penetration test was three years old.
Within 60 days, our team delivered a complete IT security risk assessment, wrote their information security program and incident response plan, conducted both internal and external penetration tests, deployed a SIEM solution with 24/7 monitoring, and implemented multi-factor authentication across all administrative accounts.
The result: zero findings on the IT examination. The examiner specifically noted the quality of the bank’s documentation and the maturity of their monitoring capabilities. The bank now operates under our managed security program, maintaining continuous compliance rather than scrambling before each examination.
Scenario: Investment Firm Stops Active BEC Attack
A Raleigh-area wealth management firm with $800 million AUM contacted us after discovering that an attacker had compromised their CFO’s email account and was monitoring wire transfer communications. The attacker had been in the mailbox for 11 days before detection.
Our digital forensics team contained the breach within two hours, identified the attacker’s access scope, determined that no fraudulent transfers had been initiated, and preserved evidence for law enforcement. We then rebuilt their email security with advanced threat protection, conditional access policies, and real-time alerting on mail forwarding rule changes.
The firm avoided potential losses estimated at $2.5 million based on the transfer amounts the attacker was monitoring. They now operate under our full managed security program with continuous email monitoring and quarterly phishing simulations.
