Overview
A local legal firm partnered with TDI Vertical to transform its legacy remote access infrastructure into a cloud-delivered Secure Access Service Edge (SASE) solution. The objective was to improve security, performance, and manageability while supporting secure access for a diverse workforce, including remote employees, legal partners, and third-party contractors.
TDI Vertical delivered a Zero Trust-aligned, policy-driven access architecture that dramatically improved user experience, enhanced compliance, and established the foundation for the firm’s long-term hybrid work and cybersecurity strategy.
Business Challenge
The Client faced increasing challenges managing a legacy VPN solution across global offices:
- Outdated VPN Infrastructure
Traditional remote access was slow, hard to manage, and increasingly vulnerable to evolving cyber threats. - Dispersed Workforce & Third-Party Access
Supporting secure, seamless access for employees, contractors, and external collaborators proved complex and inconsistent. - Regulatory Compliance Risks
Meeting privacy and security requirements across jurisdictions (e.g., GDPR, HIPAA) was hindered by limited access visibility and outdated controls. - User Friction
Long connection times, disjointed access policies, and device-specific limitations impacted employee productivity and satisfaction.
The firm required a secure, scalable, and modern remote access solution built for hybrid work and legal data sensitivity.
Solution & Design
TDI Vertical led the design and implementation of a modern SASE architecture, integrating cloud-native technologies to support secure, high-performance access from anywhere. The solution included:
- Comprehensive Assessment & Planning
Mapped existing architecture, user patterns, and compliance obligations to inform a strategic transformation roadmap. - Zero Trust Network Access (ZTNA)
Replaced legacy VPNs with identity-aware, least-privilege access policies based on role, location, and device posture. - Cloud-Based Secure Web Gateway (SWG)
Provided secure internet access with embedded threat protection and URL filtering, regardless of user location. - Firewall-as-a-Service (FWaaS)
Delivered centralized, cloud-managed traffic inspection, access enforcement, and threat detection across all traffic flows. - Data Loss Prevention (DLP)
Integrated DLP tools to monitor and control sensitive data movement, supporting compliance with legal confidentiality standards. - Phased Rollout & User Migration
Staged migration by geography and role, minimizing disruption and ensuring end-user readiness. - Centralized Policy Management
Streamlined access and threat control across users, devices, and applications from a single pane of glass.
Unique TDI Vertical Contributions
TDI Vertical delivered more than just technical implementation—we enabled transformation by:
- Legal Industry-Specific Expertise
Brought experience in supporting highly regulated environments with strict confidentiality and compliance mandates. - Custom Playbooks & Migration Templates
Provided detailed rollout guides, minimizing downtime and ensuring a repeatable, low-risk deployment model. - Identity-Centric Security Model
Applied granular access controls tailored to legal roles and devices to reduce risk without compromising user experience. - Change Management & Adoption Enablement
Offered training, documentation, and continuous support to drive smooth adoption and reduce resistance.
Results & Impact
The solution delivered rapid and measurable results across security, performance, and user experience:
- Reduction in Helpdesk Tickets
Drastically fewer remote access issues, improving IT efficiency and reducing support overhead. - Faster, More Reliable Access
Enhanced login speeds and consistent user experience across devices and locations. - Improved Security Posture
Achieved dynamic, policy-based access enforcement and real-time monitoring of user activity. - Scalability & Agility
Architecture now supports rapid onboarding of new users and external partners with minimal configuration effort.
The project played a central role in the firm’s hybrid work transformation strategy. With the foundation of a Zero Trust security model now in place, the client is better prepared to scale secure remote operations while maintaining confidentiality and compliance.
TDI Vertical continues to provide policy refinement, performance tuning, and managed security services, helping the firm advance its Zero Trust maturity and maintain resilience in a dynamic legal and regulatory environment.
Featured Case Studies
As part of a broader digital transformation and security modernization strategy, a regional Credit Union partnered with TDI Vertical to revamp the security architecture across its two critical data centers. These data centers were the foundation of the organization’s core banking, member services, and internal operations, and operated with outdated firewalls and flat, unsegmented network architecture. This left the Credit Union vulnerable to lateral threats, lacked effective traffic visibility, and presented challenges in maintaining compliance with evolving financial regulations.
