Client Overview: Our client, a top-tier hedge fund managing high-value portfolios and sensitive investor data, faced increasing cybersecurity threats and regulatory pressure. Their existing security framework lacked centralized visibility, modern threat protection, and proactive monitoring capabilities. To strengthen their security posture and safeguard critical financial data, the hedge fund partnered with NVITS to design and implement a fully modernized, compliant, and resilient security environment.
Preparation
Initial Consultation
NVITS conducted strategic consultations with the hedge fund’s executive and IT teams to understand their operational model, security concerns, and compliance requirements such as SEC, FINRA, and global data protection standards.
Detailed Assessment
Security Audit
A full audit of their existing environment was performed, including identity management, device policies, email security, network controls, and third-party access.
Risk & Threat Analysis
NVITS identified potential attack vectors including phishing, unauthorized access, data leakage, weak legacy policies, and insufficient endpoint security.
Stakeholder Engagement
We aligned all decision-makers—including IT teams, compliance officers, and investment managers—to ensure security improvements supported business and regulatory priorities.
Security Strategy Development
Modern Zero Trust Security Framework
We designed a Zero Trust–based architecture leveraging Microsoft 365 Defender, Azure AD, and cloud-native security tools to ensure identity, devices, data, and apps were fully protected.
Roadmap & Milestones
A structured roadmap was created with clear deployment phases covering identity security, endpoint protection, cloud app governance, compliance, and monitoring.
Resource Allocation
Dedicated NVITS cloud security engineers and compliance specialists were assigned to execute and validate the entire security transformation.
Security Implementation
