Cybersecurity for Financial Services and Accounting Firms in Chicago

GLBA-Aligned Cybersecurity and IT Security for Financial Advisories, Accounting Firms, and Insurance Organizations

Financial services and accounting firms handle some of the most sensitive data in the business world: client financial records, tax information, investment portfolios, and advisory relationships that carry confidentiality obligations under GLBA, SEC regulations, and professional standards. They are also among the most targeted organizations for business email compromise, wire fraud, and ransomware.

CTI Technology provides cybersecurity services built specifically for financial services and accounting firms in the Chicago area – firms that need technical controls aligned to their regulatory obligations and a security partner that understands what is at stake when client data is exposed.

The Cybersecurity Threats Financial Firms Face

Financial services firms are among the top targets for cybercrime. The threat types most active in this sector are specific, and the financial consequences are direct:

• Business email compromise and wire fraud: BEC attacks targeting financial firms involve compromising an email account – or convincing someone to act as though it has been compromised — to redirect payments, change account details, or authorize fraudulent transfers. The FBI’s 2024 Internet Crime Report identified BEC as the top financial cybercrime, with $2.9 billion in losses.
• Ransomware targeting client financial data: Financial records, tax files, and investment data are high-leverage assets for ransomware actors. A locked accounting firm cannot file returns, process payments, or serve clients.
• Third-party and vendor risk: SOC 2 expectations from enterprise clients, audit requirements, and supply chain security reviews are increasing the compliance bar for firms of all sizes. A breach at your firm affects your clients.
• GLBA compliance gaps: The Gramm-Leach-Bliley Act requires financial institutions – including many accounting firms, advisory practices, and insurance organizations – to implement specific technical safeguards. The FTC’s updated Safeguards Rule raised the bar significantly in 2023.
• Insider threats and credential exposure: Shared logins, weak password policies, and no MFA enforcement are standard findings in financial firm environments. Former employees retaining access to client data is a recurring problem.

Our Cybersecurity Services for Chicago Financial and Accounting Firms

GLBA and Safeguards Rule Compliance Assessment

We assess your current environment against FTC Safeguards Rule requirements – access controls, encryption, multi-factor authentication, incident response planning, and vendor oversight. Most firms are not as compliant as they believe, and the updated 2023 requirements added specific technical mandates that many have not addressed.

Email Security and BEC Prevention

Business email compromise starts with email. We implement Microsoft Defender for Microsoft 365 with anti-phishing policies, impersonation protection, safe links, and DMARC/DKIM/SPF configuration that prevents spoofed domain attacks. We also train users to recognize BEC patterns – the human element is part of the security posture.

Identity Management and MFA Enforcement

Every user, every account, every login – protected with MFA and Conditional Access policies that enforce security requirements regardless of device or location. Privileged access is separated. Access reviews are conducted regularly. Offboarding removes access immediately.

Data Loss Prevention and Client Data Protection

We configure DLP policies in Microsoft 365 that prevent sensitive financial data from leaving your environment through email, file sharing, or unauthorized devices. Encryption at rest and in transit is enforced. Client financial data is accessible only to those who should have access.

Incident Response Readiness

A documented incident response plan, tested backup and recovery procedures, and a security partner who knows your environment before something goes wrong. When an incident occurs, response time matters – and response quality matters more.

The Regulatory and Financial Stakes

The FTC’s updated Safeguards Rule, effective in 2023, expanded the definition of financial institution and added specific technical requirements: encryption, MFA, access controls, and incident response planning that are now enforceable obligations. Non-compliance carries civil penalties and regulatory action.

The IBM Cost of a Data Breach Report 2024 found that the financial sector’s average breach cost is $6.08 million. For a small accounting firm or advisory practice, a breach of that magnitude is an existential event, not just a line item.
