FINANCIAL SERVICESCYBERSECURITY
Financial institutions face more cyberattacks per year than any other sector. With $4.88 million as the average cost of a data breach in 2024, the stakes for banks, investment firms, and financial advisors have never been higher. Petronella Technology Group provides specialized cybersecurity and compliance services built for the regulatory complexity of financial services.
Why Financial Services Are Under Siege
Threat actors target financial institutions because of the high-value data they hold: account credentials, personally identifiable information, wire transfer authorization, and proprietary trading algorithms. Understanding these threats is the first step toward defending against them.
External Threats
- Ransomware attacks that encrypt trading platforms and client databases, demanding payment to restore operations during market hours
- Business email compromise (BEC) targeting wire transfers and ACH payments, with attackers impersonating executives or clients to redirect funds
- Credential stuffing and account takeover using leaked credentials from third-party breaches to access client accounts and trading platforms
- Supply chain attacks exploiting third-party fintech integrations, payment processors, and portfolio management software vendors
Internal Risks
- Insider threats from employees or contractors with privileged access to sensitive financial data and transaction systems
- Shadow IT where advisors use unapproved cloud storage, personal email, or messaging apps to share client financial documents
- Misconfigured access controls giving employees broader permissions than their role requires, violating least-privilege principles
- Inadequate logging and monitoring that prevents timely detection of unauthorized data access or suspicious transaction patterns
Regulatory Frameworks We Navigate
Financial services firms operate under overlapping federal and state regulations. A single compliance gap can trigger enforcement actions, fines, and loss of client trust. We help you meet every requirement while building a security posture that goes beyond checkbox compliance.
SOX Compliance
The Sarbanes-Oxley Act requires publicly traded companies to maintain internal controls over financial reporting. We implement IT controls that protect the integrity of financial data and audit trails, including access management, change control, and data backup procedures.
Explore compliance servicesGLBA Safeguards Rule
The Gramm-Leach-Bliley Act mandates that financial institutions protect consumer financial information. We develop the written information security plans, risk assessments, and technical safeguards the FTC Safeguards Rule requires, with documented evidence for examination.
Explore compliance servicesPCI DSS
Any organization processing card payments must comply with the Payment Card Industry Data Security Standard. We conduct gap assessments, implement network segmentation, configure encryption, and prepare documentation for PCI DSS Level 1-4 validation.
Explore compliance servicesSEC and FINRA Cybersecurity
The SEC and FINRA impose cybersecurity examination priorities on broker-dealers and investment advisors. We prepare firms for Regulation S-P, Regulation S-ID, and FINRA Rule 4370 requirements covering business continuity, identity theft prevention, and client data protection.
Explore compliance servicesNYDFS Cybersecurity Regulation
New York Department of Financial Services 23 NYCRR 500 applies to any financial entity operating in New York. We help implement its 23 requirements including CISO designation, penetration testing, multi-factor authentication, and the 72-hour breach notification mandate.
NIST Cybersecurity Framework
While not mandatory for all financial firms, NIST CSF provides the gold-standard control framework that regulators reference. We map your existing controls to NIST CSF categories and close gaps, giving you a defensible security program that satisfies multiple regulatory bodies.
