Introduction
As cyber threats continue to evolve, private equity firms with significant assets under management (AUM) must adopt a forward-thinking approach to cybersecurity. Financial institutions, especially those handling billions in assets, face the constant risk of data breaches, intellectual property theft, and compliance violations. For a private equity firm with over $4 billion in assets and 40 employees, securing their digital infrastructure was a critical necessity.
Prior to partnering with JNT TEK, the firm had made little investment in technology and lacked a cohesive cybersecurity strategy. This left them exposed to various threats, including unauthorized access, potential data breaches, and inefficiencies in managing their growing network. Recognizing the need for a comprehensive cybersecurity overhaul, the firm turned to JNT TEK to help build a robust security framework that could scale with their growing business and protect their sensitive data.
The Initial Challenges
Before the engagement with JNT TEK, the private equity firm faced several critical cybersecurity gaps:
Minimal Security Investment: The firm had not implemented adequate cybersecurity measures, relying on outdated systems and ad-hoc processes that left them vulnerable.
Lack of Network Security: Network access controls were either non-existent or insufficient, with no centralized visibility into potential threats across their infrastructure.
Inconsistent Device Management: Devices, particularly those used by employees working remotely or using their own devices (BYOD), lacked security measures, increasing the risk of data breaches.
Disjointed IT Systems: The firm's various applications and systems were not integrated, and they were still using on-premise servers for data storage, which made remote work difficult and posed security challenges.
No Centralized Identity Management: The firm struggled with managing user access and authentication across a growing portfolio of line-of-business (LOB) applications, which could lead to inefficiencies and potential unauthorized access.
Given these challenges, the firm required a comprehensive and strategic approach to cybersecurity, one that could address immediate vulnerabilities and ensure long-term security.
JNT TEK's Approach to Cybersecurity Overhaul
1. Full Cybersecurity Risk Assessment
JNT TEK began by conducting a full cybersecurity risk assessment, which included:
Asset and Risk Identification: Identifying critical assets, sensitive data, and potential risks across the firm's network and applications.
Vulnerability Assessment: Analyzing existing infrastructure for vulnerabilities, such as outdated software, weak access controls, and gaps in monitoring and response.
Compliance Review: Assessing the firm's adherence to relevant compliance standards, such as SOC 2, GDPR, or other applicable regulations.
Threat Landscape Analysis: Reviewing the potential threats the firm could face, including cyberattacks targeting financial institutions, data breaches, and insider threats.+
The assessment results allowed JNT TEK to design a comprehensive, multi-phase strategy that addressed both immediate and long-term cybersecurity needs.
2. Phased Implementation of Key Security Controls
Over the next two years, JNT TEK guided the firm through the implementation of essential security measures in a phased approach, aligning with the firm's operational needs and strategic objectives.
Phase 1: Strengthening Network and Access Controls
Network and Wireless Overhaul: JNT TEK revamped the firm's network and wireless infrastructure, ensuring high performance, redundancy, and secure access across all locations. This included the installation of advanced firewalls, intrusion prevention systems (IPS), and enhanced network segmentation to limit access to sensitive data.
Network Access Controls: JNT TEK implemented network access control (NAC) policies, ensuring that only authorized devices could access the firm's network. This helped prevent unauthorized devices from connecting to critical systems and data.
Phase 2: Identity and Access Management
Single Sign-On (SSO) for LOB Applications: JNT TEK implemented SSO for all line-of-business applications, enabling employees to securely access their work applications with a single set of credentials. This reduced the risk of credential theft and simplified user management.
Multi-Factor Authentication (MFA): MFA was rolled out across the firm's systems to provide an additional layer of protection for all user accounts, ensuring that even if credentials were compromised, unauthorized access could be prevented.
Phase 3: Securing Data and Implementing Cloud Solutions
Data Migration to SharePoint: JNT TEK helped the firm migrate their on-premise data to SharePoint for better collaboration, data security, and version control. SharePoint's cloud-based storage provided better access management and scalability.
Data Loss Prevention (DLP): DLP policies were implemented to prevent the accidental or intentional leakage of sensitive data. This allowed the firm to set rules to block, monitor, or encrypt sensitive information before it could be shared outside the network.
Phase 4: Endpoint and Device Management
Transition to Microsoft Intune: JNT TEK migrated the firm from traditional Active Directory (AD) to Microsoft Intune, enabling mobile device management (MDM) and security management for all endpoints, including smartphones, laptops, and tablets. This solution ensured that all devices were compliant with firm-wide security policies, regardless of where employees worked.
Phase 5: Advanced Security Measures
Privileged Access Management (PAM): JNT TEK implemented a PAM solution to protect highly sensitive accounts and credentials, including administrator and root-level access, which are often targeted in cyberattacks. PAM allowed for better control over privileged accounts, limiting access to critical systems and providing audit trails.
Zero Trust Architecture: JNT TEK introduced a Zero Trust security model, which ensures that no device or user is trusted by default. Every access request was authenticated and verified before being granted, ensuring that only legitimate users and devices could access the firm's systems and data.
Advanced Email Filtering: To protect against phishing and other email-based attacks, JNT TEK deployed advanced email filtering solutions that automatically detect and block malicious emails, providing an additional layer of defense against social engineering attacks.
Phase 6: Conditional Access Policies and BYOD Security
Conditional Access Policies: JNT TEK implemented conditional access policies that required employees to meet certain criteria (e.g., device health, network location) before accessing firm resources. This ensured that only trusted devices and users could access sensitive data and applications.
BYOD Security: With many employees using personal devices, JNT TEK implemented strict BYOD policies, enforcing encryption, password protection, and compliance with the firm's security protocols.
