Financial services cybersecurity is facing unprecedented risk
Roughly 65% of financial organizations dealt with ransomware issues in 2024, according to the Financial Services Information Sharing and Analysis Center (FS-ISAC). Recovery costs have climbed to an average of $2.58 million per incident, with attackers targeting the sector’s high-value data and critical infrastructure.
This sustained pressure has driven financial firms to make serious investments in cybersecurity solutions, with Zero Trust principles increasingly at the center of their defense strategy.
For wealth managers, asset managers, and financial advisors—set to be responsible for a predicted $171 trillion in global assets by 2028—cybersecurity is now a fundamental business imperative. With 71% of asset managers fielding investor cybersecurity questions during fundraising and 88% of financial executives fearing client withdrawal after attacks, security posture now directly impacts fundraising, client retention, and valuation.
Ransomware groups have recognized this vulnerability. The MOVEit supply chain attack alone compromised over 2,700 organizations and 93 million individuals, impacting major institutions including TD Ameritrade, Charles Schwab, Fidelity Investments, and TIAA.
RansomHub emerged as 2024’s most prolific threat actor, claiming responsibility for over 500 attacks targeting the financial sector, using advanced techniques to bypass traditional defenses.
Compounding the threat, third-party risk appears to have become far more volatile.
SecurityScorecard data reveals that 97% of the top 100 U.S. banks experienced a third-party breach in 2024. Financial services accounted for 16% of all third-party breaches globally, with 81% of those breaches involving system intrusion and credential reuse in third-party environments.
The cost of cyberattacks for financial institutions
A 2024 ransomware attack against Insight Partners, a prominent venture capital firm, underscores the escalating risk to the investment sector. The attack began with a methodical social engineering campaign designed to gain initial access, followed by months of covert data encryption.
Notably, Insight Partners’ portfolio includes multiple cybersecurity companies, yet it still fell victim to the attack because traditional perimeter-based security failed once attackers gained internal access. Systems that should have been isolated were implicitly trusted.
Following the breach, Insight Partners filed mandatory data breach notifications with multiple state attorney generals and began notifying over 12,600 affected individuals.
The compromised data included details on limited partners, fund information, and portfolio companies, highlighting the power of such incidents to create reputational challenges for investment firms.
In 2025, three federal lawsuits were filed within months of each other highlighted the increasing risk and fallout of cyberattacks in the financial industry. The cases, Boutot v. Norway Savings Bank, Spohrleder v. CoVantage Credit Union, and Maggio v. Byzfunder NY LLC, describe how attackers allegedly accessed customer data held by two financial institutions and one non-bank lender.
How Zero Trust strengthens financial services cybersecurity
As cyberattacks become more frequent, costly, and reputationally damaging, trust has become one of the financial sector’s most valuable assets. From ransomware and supply chain compromises to tightening regulatory scrutiny, investment firms now face risks that extend far beyond IT.
Zero Trust has emerged as a strategic response, reshaping how organizations protect data, meet compliance requirements, and reassure clients and investors. The close connection between cybersecurity, valuation, and growth is increasingly evident, particularly as recent breaches reveal the limitations of traditional perimeter defenses.
Firms embracing Zero Trust principles are gaining measurable advantages in resilience, reputation, and long-term confidence, illustrating the critical intersection of cybersecurity and financial success.
However, Zero Trust architecture represents a fundamental shift in cybersecurity thinking for investment companies.
Treating every user, device, and application as potentially compromised allows for the creation of a hardened interior beneath the traditional perimeter defense, placing security at the heart of every process.
The necessity of such controls is demonstrated by the 2024 Fidelity Management & Research breach, in which attackers created two fraudulent customer accounts and used them to access other customers’ sensitive data through a broken access control flaw.
This allowed them to view Social Security numbers (SSNs), driver’s license information, and financial account details.
Perimeter defenses cannot prevent access-based exploits like this, but Zero Trust measures such as least-privilege access, micro segmentation, and real-time access monitoring would have cut off the attack before it could even begin.
How Zero Trust supports financial services compliance requirements
In the face of increased threats, the regulatory landscape has intensified dramatically. New Securities and Exchange Commission (SEC) cybersecurity rules, effective December 2023, require material incident disclosure within four business days, along with annual cybersecurity risk management reporting.
The SEC settled charges against four companies in October 2024 for disclosure failures, signaling aggressive enforcement ahead.
Since 2021, U.S. financial services firms have faced approximately $400 million in regulatory penalties over cybersecurity breaches and inadequate security controls. Capital One incurred $80 million in penalties from the Office of the Comptroller of the Currency (OCC), plus a $190 million class-action settlement for its 2019 cloud breach affecting 100 million customers.
The SEC fined Intercontinental Exchange $10 million for failing to disclose a hack and imposed $2.1 million on RR Donnelley for insufficient cybersecurity controls during a ransomware attack.
Beyond the SEC, firms must navigate Financial Industry Regulatory Authority (FINRA) requirements, state mandates such as New York’s Stop Hacks and Improve Electronic Data Security (SHIELD) Act and California’s privacy laws, and various worldwide regulations, including the EU General Protection Regulation (GDPR), The EU Markets in Financial Instruments Directive II (MiFID II), and System and Organization Controls (SOC) 2 Type II.
Adding to the complexity, breach notification laws differ across the 50 states, while Payment Card Industry Data Security Standard (PCI DSS) compliance is mandatory for firms that process payments. This fragmented landscape makes unified security frameworks essential.
Gaining the International Standards Organization/International Electrotechnical Commission (ISO/IEC) 27001 certification has become increasingly critical for investment firms seeking to attract European clients and gain a competitive advantage in U.S. markets.
Strategic roadmap for implementing Zero Trust
CISOs at investment firms can adopt a phased approach to Zero Trust implementation, balancing immediate security improvements with long-term strategic goals.
The following timeline provides a sample framework for systematic deployment that allows business operations to remain active.

How ThreatLocker supports Zero Trust cybersecurity for financial institutions
Zero Trust implementation requires continuous authentication and authorization for every access request, along with explicit access controls.
ThreatLocker exemplifies these principles for financial institutions.
Application Allowlisting prevents unauthorized software, such as unapproved trading tools or shadow IT applications, from executing on endpoints, supporting regulatory expectations like secure change control and software integrity.
Ringfencing™ enforces granular access boundaries so applications, including core banking platforms, SWIFT clients, or market-data terminals can only interact with the data and processes explicitly allowed, limiting lateral movement and reducing the blast radius of a compromised account or system.
The Defense Against Configurations (DAC) dashboard can help you ensure ISO/IEC 27001 compliance through comprehensive access controls, continuous monitoring, and detailed audit trails that demonstrate security governance.
EDR Real-Time Threat Detection recognizes abnormal behavior instantly and enforces predefined policies to isolate devices, shut down risky processes, and block attacker pathways in real time.
Cybersecurity in the financial industry requires a Zero Trust future
Delaying Zero Trust adoption exposes firms to escalating risk—financial, operational, and reputational.
Those implementing strong cybersecurity programs, on the other hand, achieve measurable returns: Organizations with strong incident response plans reduce breach-related costs by an average of $1.49 million, while security AI and automation prevent breaches that would cost an average of $2.22 million.
The evidence overwhelmingly demonstrates that cybersecurity has evolved from an IT concern to a strategic business imperative. Companies with SOC 2 compliance create trust advantages, while cybersecurity excellence differentiates firms in competitive wealth management markets.
Strong cyber defenses now function as powerful differentiators, and clients now routinely ask about security protocols in the same breath as investment performance.
Success requires executive-level commitment, adequate resource allocation, and continuous improvement.
Just as in investment, there is no such thing as an immediate, instant return. But in this high-stakes environment, robust cybersecurity forms the foundation for sustained growth and ongoing client trust.
It is money well spent.
