  • These areas are frequent sources of both SEC enforcement actions and securities fraud class action lawsuits.
• Insider Trading Crackdown:
  • Shadow trading: The SEC is prosecuting cases where insiders use confidential information from one company to trade stocks of economically linked companies (e.g., competitors).
    • This builds upon jury verdicts from previous years that established precedent for shadow trading prosecutions.
  • Individuals & foreign actors: The SEC continues to pursue domestic and foreign individuals involved in multi-jurisdictional insider trading schemes.
  • Rule 10b5-1 plans: Recent trial victories confirm that trading on insider information—even under a Rule 10b5-1 plan—can still result in prosecution.
• Accounting and Disclosure Fraud:
  • Inflated financial reporting: The SEC actively pursues companies and executives who falsify financial records or inflate performance metrics due to poor corporate governance.
  • Controls failures: Significant fines are imposed on firms with inadequate internal controls that allow fraud to go undetected.
    • Example: Executives have been charged for falsifying records; some companies have avoided charges by demonstrating strong internal controls that exposed misconduct.
• Investment Advisers – Fiduciary Duty & Fraud:
  • Breaches of fiduciary duties: Advisers face charges for failing to disclose conflicts of interest or misallocating trades between personal accounts and client portfolios.
  • Targeting fraud over technical violations: The SEC prioritizes cases involving actual fraud rather than just registration or procedural violations (e.g., fraudulent crypto asset certificates).
• Protection of Retail Investors:
  • The SEC prioritizes enforcement actions involving harm to retail investors—especially related to new technologies like AI.
    • This includes crackdowns on misrepresentations about AI capabilities and other emerging tech risks.

Key Points: SEC Enforcement Areas & Priorities 

• AI and Emerging Technologies
  • AI Washing:
    • The SEC and DOJ are actively pursuing civil and criminal actions against company executives accused of making materially false or misleading statements about their company’s AI capabilities.
  • Dedicated Unit:
    • The SEC has replaced its Crypto Assets and Cyber Unit with the Cyber and Emerging Technologies Unit (CETU).
    • CETU targets technology-driven fraud, including AI washing, social media fraud, account takeovers, and hacking.
• Cryptocurrency
  • Fraudulent Schemes:
    • Enforcement efforts have shifted focus from technical registration violations to combating actual fraud and manipulation within the crypto sector.
  • Higher-Profile Cases:
    • Current enforcement targets include significant scams such as fraudulent crypto asset pyramid schemes and fake trading platforms.
  • Regulatory Focus:
    • In 2025, the SEC established a new Crypto Task Force to create clearer regulatory frameworks—indicating a move toward transparent regulation rather than relying solely on enforcement actions.
• Market Abuse
  • Market Manipulation Schemes:
    • The SEC continues to file complaints against individuals orchestrating pump-and-dump schemes using deceptive press releases, promotional materials, and manipulative trading tactics.
  • Protection of Confidential Information:
    • Following several high-profile settlements in 2024, the SEC remains vigilant in investigating failures to safeguard material non-public information and other related market abuse activities.

Areas of Decreased SEC Focus 

• ESG and Climate Disclosures
  • Withdrawal of Rules:
    • In March 2025, the SEC made a significant reversal by voting to stop defending its climate-related disclosure rules in court.
  • Reduced Federal Oversight:
    • A shift in administration has led to decreased emphasis on ESG-related enforcement and rulemaking at the federal level.
• Off-Channel Communications
  • Decline in Enforcement Activity:
    • After widespread enforcement sweeps targeting “off-channel communications” (such as texting) in 2024, related SEC activity is expected to decline further in 2026.
• Enforcement Outcomes
  • Successful Defenses:
    • While rare, it is possible for defendants to successfully contest an SEC enforcement action.
    • Common defenses focus on challenging the legal requirements of securities fraud—specifically, by disputing materiality, scienter (intent), or breach of duty.

Examples of Successful Insider Trading Defenses 

• SEC v. SolarWinds (Partial Dismissal, July 2024):
  • A federal judge dismissed most of the SEC’s claims against SolarWinds and its CISO in a high-profile cybersecurity enforcement case.
  • The court ruled that alleged failures in internal accounting and disclosure controls due to cybersecurity deficiencies do not automatically constitute “accounting problems.”
  • General public statements about cybersecurity were deemed “corporate puffery,” not specific enough for investor reliance.
  • Claims regarding post-breach disclosures in Form 8-K filings were rejected, as the company’s understanding of the incident was still evolving.
  • The defense demonstrated that two misclassified incidents cited by the SEC did not prove systemic deficiencies in disclosure controls.
• Pre-Existing Trading Plans (Rule 10b5-1):
  • Rule 10b5-1 allows insiders to set up pre-arranged trading plans when they are not in possession of material non-public information.
  • Case Study: In certain SEC actions, defendants have shown that trades occurred automatically under a valid pre-existing plan, with no control over timing once established—providing a strong defense against insider trading allegations.
• Public Information Defense:
  • This defense asserts that the information used to trade was already publicly available (e.g., via news outlets, SEC filings, analyst reports).
  • Case Study: An executive successfully argued that all relevant information had been disclosed publicly before their trades took place.
• The Mosaic Theory:
  • Sophisticated investors may argue their decisions were based on assembling a “mosaic” of non-material, public information rather than on any single piece of inside information.
  • Case Study: Defendants have demonstrated trades were based on a combination of financial reports, industry trends, and analyst calls—not on confidential data.

Examples of Successful Accounting Fraud Defenses in SEC Enforcement Actions

• Lack of Intent (Scienter):
  • For fraud charges to hold, the SEC must prove intent to deceive.
  • Case Study: Defendants may show they relied on incorrect but seemingly legitimate data or acted in good faith. Supporting evidence can include testimony, emails, or other communications showing no deliberate effort to mislead.
• Following Professional Advice:
  • Defendants can argue they followed advice from qualified experts (lawyers/accountants) and believed their actions were lawful.
  • Case Study: Success depends on showing all relevant facts were disclosed to advisors and that actions taken were based on expert guidance.

Other Notable Defenses & Precedents

• Challenging SEC Authority – Kokesh v. SEC (2017):
  • The Supreme Court ruled that disgorgement is a penalty subject to a five-year statute of limitations.
  • Impact: Limits the SEC’s ability to seek disgorgement for alleged misconduct occurring more than five years before suit was filed.
• SEC Overreach:
  • Defendants sometimes argue that the SEC has exceeded its authority or applied rules too broadly.
  • Case Study: In SolarWinds, successful arguments included claims that internal accounting control rules should not be stretched to cover non-financial matters like cybersecurity.

Key Elements of a Strong Cybersecurity Program That the SEC Expects Companies to Have (2026 Update)

Cybersecurity Frameworks Align with SEC Expectations

Securities fraud class action lawsuits are increasingly filed when companies fail to meet the SEC’s expectations around cybersecurity governance, risk management, and timely disclosure of material cybersecurity incidents. While the SEC does not explicitly endorse a single cybersecurity framework, several established frameworks align closely with what regulatory bodies require for robust corporate governance and compliance.

By adopting one or more of these recognized frameworks, companies can strengthen their cybersecurity program, demonstrate sound risk management practices, and reduce exposure to securities fraud litigation and SEC enforcement actions.

NIST Cybersecurity Framework (CSF)

The NIST CSF is widely recognized in both regulatory developments and industry best practices as an effective approach for managing cybersecurity risks. It provides a comprehensive roadmap for building a strong cybersecurity program that supports the SEC’s disclosure requirements and aligns with expectations for incident response and reporting.

Key Functions: The CSF is organized around five core functions:

• Identify: Understand and manage cybersecurity risk to systems, data, and assets.
• Protect: Develop and implement safeguards to ensure the delivery of critical services.
• Detect: Implement continuous monitoring to identify cybersecurity events.
• Respond: Develop and execute activities to contain the impact of an incident.
• Recover: Plan for resilience and restore systems or assets affected by a breach.

Relevance to SEC Compliance: The NIST CSF’s structured approach helps companies:

• Establish processes for determining the materiality of cybersecurity incidents “without unreasonable delay.”
• Maintain continuous monitoring as part of their overall risk management strategy.
• Develop effective incident response plans that support accurate disclosures in public filings—helping avoid potential securities fraud class actions or SEC enforcement actions related to inadequate cyber risk oversight.

ISO/IEC 27001

ISO 27001 is a globally recognized standard for establishing an Information Security Management System (ISMS). This framework provides a systematic approach to managing sensitive information and strengthening a company’s cybersecurity program—key elements under increasing scrutiny from the SEC and other regulatory bodies.

Key Components:

• Confidentiality: Protecting data from unauthorized access.
• Integrity: Safeguarding the accuracy and completeness of information.
• Availability: Ensuring authorized users have access to information when needed.

Relevance to SEC Compliance: By implementing ISO 27001, companies can:

• Address third-party risks—a growing concern in recent securities fraud litigation and regulatory developments.
• Establish detailed processes for incident management and ongoing risk assessment.
• Document security controls and procedures, which aligns with the SEC’s focus on demonstrable corporate governance and disclosure controls.

Center for Internet Security (CIS) Controls

The CIS Controls offer a prioritized set of actions to defend against common cyberattacks. Highly practical and prescriptive, this framework supports companies in building a cybersecurity program that meets both internal needs and external regulatory expectations.

Key Components:

• Basic Controls: Essential, high-priority safeguards.
• Foundational Controls: Advanced measures that build on the basics.
• Organizational Controls: Policy and procedural controls supporting overall security governance.

Relevance to SEC Compliance: The CIS Controls emphasize verifiable, actionable security measures—providing clear evidence of a company’s commitment to cybersecurity risk management. This can be crucial in demonstrating “reasonable” steps to prevent cybersecurity incidents, helping reduce exposure to SEC enforcement actions or securities class action lawsuits related to inadequate protections.

COBIT Framework

Developed by ISACA, the COBIT framework is designed for IT governance and resource management. It bridges the gap between technical cybersecurity measures and broader business objectives—a key theme in recent corporate governance guidance from regulatory bodies.

Relevance to SEC Compliance: COBIT’s focus on integrated governance and risk management aligns directly with the SEC’s requirements for disclosing management’s role in identifying and managing material cybersecurity risks. This helps organizations demonstrate that cybersecurity is embedded within their overall risk management strategy—critical for both compliance and defense against securities class actions.

How to Use These Frameworks for SEC Compliance

• Holistic Approach: The most effective compliance strategy often combines elements from multiple frameworks. For example, use NIST CSF for high-level governance while applying CIS Controls for technical implementation.
• Tailored Implementation: Adapt frameworks to fit your organization’s unique risks, business goals, and industry context. The SEC evaluates whether companies take “reasonable” steps tailored to their circumstances—demonstrating thoughtful customization strengthens your position in both regulatory review and potential litigation.
• Documentation: Whatever framework you choose, thorough documentation is essential. Keeping clear records of risk assessments, incident response plans, third-party reviews, and governance structures provides critical evidence during SEC scrutiny or in response to securities class action lawsuits related to cybersecurity incidents.

Board Reporting on Cybersecurity Incidents

Effective board reporting on cybersecurity incidents is crucial for corporate governance and regulatory compliance. By translating technical activities into business-relevant metrics, organizations empower their boards to understand the financial, operational, and legal implications—including potential exposure to securities fraud class action lawsuits.

Strategic and Risk-Focused Metrics

These metrics demonstrate how cybersecurity initiatives align with business objectives and risk management:

• Cyber Risk Exposure (Quantified): Present the likelihood and financial impact of threats such as ransomware or data breaches. Use metrics like Annualized Loss Expectancy (ALE) to quantify risks that could lead to securities fraud class action lawsuits.
• Return on Security Investment (ROSI): Show the financial benefits of security investments—how new controls or tools have reduced potential losses or improved efficiency.
• Third-Party Risk Score: Track the average security rating of vendors and partners to highlight supply chain risk management—a growing area of regulatory focus.
• Board Engagement Frequency: Measure how often cybersecurity is discussed at board meetings and demonstrate alignment with the company’s risk appetite statement.

Performance and Operational Metrics

These metrics provide insight into the effectiveness of the organization’s cybersecurity program:

• Security Posture & Maturity: Report maturity based on frameworks like NIST CSF; show trends over time to reflect continuous improvement.
• Mean Time to Detect (MTTD): Track average detection time for incidents—improving MTTD indicates stronger monitoring capabilities.
• Mean Time to Respond/Remediate (MTTR): Measure response time from detection to containment and system restoration.
• Vulnerability Management Status: Use grades or scores (“patching cadence”) to show how quickly critical vulnerabilities are addressed—delays here can increase litigation risk.

Compliance and Corporate Governance Metrics

Boards must oversee compliance with evolving regulations and internal controls for managing cybersecurity risks:

• Compliance Score: Summarize adherence to standards like ISO 27001 or NIST; highlight significant gaps or changes relevant for SEC enforcement actions.
• Audit Findings: Present results from internal/external audits, especially high-risk deficiencies and remediation plans.
• Employee Awareness: Share outcomes from phishing simulations or training completion rates—demonstrates proactive management of human risk factors.
• Policy Violations: Report severe security policy violations that could expose the company to regulatory scrutiny or legal risk.

Threat Landscape Metrics

Contextualizing external threats helps boards understand environmental risks:

• Industry Threat Trends: Update on emerging threats and regulatory developments impacting the sector—and how your company is adapting.
• Industry Benchmarks: Compare security posture against peers for context on competitive standing and best practices.
• Intrusion Attempts: Quantify detected and blocked attacks to illustrate current threat levels.

Best Practices for Presenting Metrics to the Board

• Executive Summary First: Start with a high-level overview of top risks, overall security posture, and recent incidents relevant for corporate governance.
• Visualizations: Use dashboards, heatmaps, and trendlines to make complex information easy for directors to grasp quickly.
• Align with Business Strategy: Link cybersecurity efforts directly to revenue protection, customer trust, compliance obligations, and operational resilience.
• Emphasize Trends Over Data Points: Focus on whether key metrics are improving over time—a critical consideration for both regulators and investors.

Other Regulatory Developments

Beyond SEC enforcement actions, a dynamic regulatory landscape continues to evolve at the federal, state, and sector-specific levels. These regulatory developments demand that organizations strengthen their cybersecurity programs, enhance corporate governance, and proactively manage cybersecurity risks to avoid significant fines, legal penalties, or even securities class action lawsuits.

Sector-Specific Regulations

Financial Services (FTC, FDIC, NYDFS)

• FTC Safeguards Rule: Enforced by the Federal Trade Commission, this regulation requires financial institutions to implement comprehensive information security programs. Institutions must conduct risk assessments, encrypt sensitive data, and develop robust incident response plans. The FTC’s scope now extends beyond traditional banks to include a wide range of financial service providers.
• FDIC: The Federal Deposit Insurance Corporation emphasizes resilience in the banking sector. In 2024, the FDIC undertook a major analysis to ensure that no institution is “too big to fail,” reinforcing expectations for strong cybersecurity and risk management practices.
• NYDFS Cybersecurity Regulation: The New York State Department of Financial Services mandates that covered financial services entities maintain comprehensive cybersecurity programs—complete with risk assessments, written policies, and detailed incident response protocols.

Healthcare (HIPAA)

• HIPAA Security Rule: The Health Insurance Portability and Accountability Act sets national standards for protecting patient health information. Covered entities and business associates must implement administrative, physical, and technical safeguards. The Breach Notification Rule requires timely disclosure of incidents to both affected individuals and authorities.

Defense Contractors (DFARS & CMMC)

• DFARS & CMMC: The Defense Federal Acquisition Regulation Supplement (DFARS) requires defense contractors to implement NIST SP 800-171 controls for safeguarding Controlled Unclassified Information (CUI). The Cybersecurity Maturity Model Certification (CMMC) further builds on this by introducing maturity levels tied to the sensitivity of information handled.

State and Global Regulatory Developments

As the regulatory landscape continues to expand beyond SEC enforcement actions, organizations must adapt to evolving state laws and global standards that impact their cybersecurity programs, data governance, and risk management frameworks. Failure to comply with these regulations can lead to significant fines, reputational damage, or even securities fraud class action lawsuits.

State-Level Data Privacy Regulations

New York (SHIELD Act)

• The Stop Hacks and Improve Electronic Data Security (SHIELD) Act broadens the definition of private information and requires businesses operating in New York to implement reasonable administrative, technical, and physical safeguards. This statute emphasizes the importance of a robust cybersecurity program as part of good corporate governance.

Illinois (BIPA)

• The Biometric Information Privacy Act (BIPA) mandates that companies collecting biometric data—such as fingerprints or facial recognition—obtain informed consent and maintain strict protocols for data storage, use, and destruction. Non-compliance has resulted in high-profile class action lawsuits and substantial settlements.

Emerging Technology Regulations

Federal agencies are increasingly focused on the risks associated with emerging technologies such as artificial intelligence (AI) and cryptocurrency.

• AI Regulation: The European Union’s AI Act—set to take full effect in 2026—regulates AI systems based on their risk level. In the U.S., the FTC has begun enforcing actions against companies making misleading claims about AI capabilities.
• Cryptocurrency Regulation: Federal agencies including the FTC and the SEC’s Crypto Task Force have ramped up oversight and enforcement activities targeting fraudulent practices and inadequate cybersecurity in the crypto sector.

Global Data Privacy Standards

General Data Protection Regulation (GDPR):

• The GDPR imposes strict requirements for data handling, privacy practices, and breach notification on organizations worldwide that process personal data of EU residents. Non-compliance can result in significant financial penalties and increased litigation risk.

Securities Class Action Litigation Trends

Settlement values for securities fraud class actions have soared to record highs, even as the overall number of filings remains steady.

• Shift to high-value cases: Plaintiff law firms are increasingly targeting fewer but larger, high-stakes cases—especially in the tech sector—where potential recoveries are substantial.
• Dominance of mega filings: Cases involving over $5 billion in claimed losses accounted for most of the total losses in early 2025.
• AI-related claims surge: AI-related securities fraud class actions are on the rise, with many alleging “AI washing”—misrepresenting or exaggerating AI capabilities. Notably, these claims have proven more resilient to motions to dismiss than traditional securities litigation.
• Growth in data security cases: Data breach class actions continue to increase in both frequency and complexity. Courts are showing more leniency on standing issues, making multimillion-dollar settlements increasingly common.

Conclusion

In recent years, the landscape of securities fraud class action lawsuits and regulatory developments has evolved dramatically, driven by emerging risks such as cybersecurity incidents and advances in technology like AI. As we look toward 2025, companies and their executives must remain vigilant—staying informed about litigation trends and regulatory expectations is essential for mitigating potential liabilities.

The SEC has ramped up enforcement efforts targeting fraudulent activities, insider trading, and violations that threaten market integrity. This robust regulatory environment places a premium on compliance and transparency to avoid severe penalties and reputational harm.

Cybersecurity remains a paramount concern. The growing impact of data breaches on shareholder value has fueled an uptick in securities class actions. Companies are now expected to implement comprehensive cybersecurity measures and promptly disclose incidents to stakeholders—regulatory bodies have made clear that preparedness is non-negotiable.

Looking ahead, the regulatory landscape will only become more dynamic with continuous updates designed to address new risks. As technology evolves—and as malicious actors become more sophisticated—it is critical for organizations to leverage advanced tools like AI for compliance monitoring while remaining agile in their risk management strategies.
