Fast, reliable IT support with continuous security and compliance you can trust

Financial services firms—and any business where downtime, security gaps, or compliance failures aren’t an option—need IT that simply works. Plexus IT delivers rapid-response support, proactive security monitoring, and compliance-aligned infrastructure for Los Angeles–based organizations across industries. From recurring server outages and network-wide malware incidents to misconfigured systems that exposed serious security risks, we resolve issues quickly and implement safeguards to prevent them from returning. Below are real examples of how we help clients stay secure, compliant, and operational.

Because we work with organizations where security and confidentiality are critical, we don’t publicly list client names or contact details.
We believe protecting our clients’ visibility is part of protecting their security. We’re happy to discuss our experience through anonymized case studies or provide references privately when appropriate.

Fast, reliable IT and compliance-ready security for a growing private equity firm

A Los Angeles–based private equity firm with over 20 years in business and approximately 15 employees began working with Plexus IT more than 14 years ago while experiencing growing pains as their operations expanded. Their previous IT provider was unreliable, slow to respond, and unable to support the firm’s increasing security and compliance needs. Frequent system issues and inconsistent support were putting productivity and confidence at risk.

Plexus IT was engaged to stabilize the firm’s IT environment and build a secure, scalable foundation for long-term growth. We migrated the firm to Microsoft 365, improving reliability, collaboration, and security across the organization. A secure data room solution was implemented to protect sensitive deal and investor documents with granular access controls and full audit visibility.

As the firm prepared to become a Registered Investment Advisor (RIA), Plexus IT aligned the IT environment with compliance requirements, strengthening identity management, logging, and security controls. When a potential security breach was suspected, Plexus IT responded quickly to secure the environment, investigate the incident, and implement additional safeguards to reduce future risk.

Today, after more than 14 years as a Plexus IT client, the firm operates in a stable, compliance-ready IT environment supported by:

Ongoing penetration testing
Cybersecurity awareness training
Endpoint Detection & Response (EDR)
Conditional Access Policies and Identity Protection
Patch management
Immutable data and email backups

The result is a reliable, secure IT platform that supports both daily operations and long-term regulatory requirements.

High-touch, responsive IT support for a rapidly scaling venture capital firm

A Los Angeles–based venture capital firm has partnered with Plexus IT for over 11 years after outgrowing a large, impersonal IT provider that was slow to respond to support requests. As the firm evolved, it needed an IT partner that could move at its pace while strengthening security, reliability, and scalability.

Plexus IT took over full management of the firm’s Microsoft 365 environment, improving visibility, reliability, and data protection. We implemented security safeguards to protect sensitive communications and investor information, while providing ongoing cybersecurity awareness training to reduce human risk.

During the course of the partnership, the firm grew from approximately 10 employees to more than 50. Plexus IT supported a major office expansion—from a single suite to an entire floor—including the design and deployment of a new IT infrastructure and a modern video conferencing system across multiple conference rooms to support collaboration with founders, investors, and internal teams.

Plexus IT also coordinates ongoing penetration testing of both cloud and on-premises infrastructure. A third-party penetration testing firm described the firm’s security posture as “setting the Gold Standard.”

Today, the firm’s environment is continuously protected through:

Ongoing penetration testing
Cybersecurity awareness training
Endpoint Detection & Response (EDR)
Conditional Access Policies and Identity Protection
Patch management
Immutable data and email backups

The result is fast, reliable IT support paired with enterprise-grade security that continues to scale with the firm’s growth.

Rapid office launch and secure IT foundation for an international family office

A newly formed family office with operations in Los Angeles and Europe partnered with Plexus IT more than three years ago and required a complete IT setup on an aggressive timeline. With less than two weeks’ notice, Plexus IT designed, deployed, and secured a new 10,000-square-foot office in a Los Angeles high-rise building to support the launch of their U.S. operations.

Plexus IT delivered reliable internet connectivity, secure wireless and LAN infrastructure, and a modern video conferencing solution to enable seamless international collaboration. We established and continue to manage the family office’s Google Workspace environment, ensuring secure access, data protection, and efficient collaboration across locations.

Given the sensitivity of both financial and personal information, Plexus IT implemented layered security controls and ongoing monitoring to protect the family office from cyber threats while ensuring business continuity and operational resilience.

Ongoing protections include:

Regular penetration testing
Cybersecurity awareness training
Endpoint Detection & Response (EDR)
Conditional Access Policies and Identity Protection
Patch management
Immutable data and email backups

After more than three years as a Plexus IT client, the family office operates on a secure, reliable IT foundation designed for discretion, privacy, and global operations—and we look forward to supporting their continued growth for many years to come.

Reliable IT and business continuity for a growing law firm

A Los Angeles–based law firm with more than 20 years in business and over 20 employees partnered with Plexus IT nearly 15 years ago while facing IT support challenges associated with growth. Their previous provider was slow to respond and unable to deliver the reliability, security, and continuity required for legal operations.

Plexus IT upgraded the firm’s on-premises Exchange Server and implemented a robust backup and business continuity solution to protect email and critical case data. We also deployed a new time-tracking system to support billing accuracy and overhauled the firm’s network LAN infrastructure to improve performance, reliability, and security across the office.

In addition to stabilizing daily operations, Plexus IT implemented layered cybersecurity protections to reduce risk and ensure long-term resilience for the firm.

These protections include:

Ongoing penetration testing
Cybersecurity awareness training
Endpoint Detection & Response (EDR)
Conditional Access Policies and Identity Protection
Patch management
Immutable data and email backups

After nearly 15 years as a Plexus IT client, the firm continues to rely on dependable IT systems that support productivity, security, and business continuity. The firm has also referred Plexus IT to numerous other organizations, where we have provided IT operations support, data recovery, digital forensics, and expert witness services—further reflecting the trust built through a long-term partnership.

Long-term, reliable IT support for a growing home services organization

A Los Angeles–based HVAC and electrical contractor began as a small, family-run business and partnered with Plexus IT more than 20 years ago. At the time, the company was a classic “mom and pop” operation with limited technology needs. As the business expanded, dependable IT systems became essential to supporting office staff, field technicians, scheduling, and customer service operations.

Over two decades, the company has grown into one of the largest professional home services providers in Los Angeles, now employing nearly 100 people. Throughout that growth, Plexus IT has served as a long-term IT partner—evolving the company’s technology alongside the business to ensure reliability, scalability, and security.

Plexus IT designed and manages a stable IT environment that supports daily operations and minimizes downtime during peak service periods. This includes modernizing infrastructure, maintaining secure remote access for field teams, and ensuring office systems remain fast and dependable as staffing and workload increased.

In addition to responsive day-to-day support, Plexus IT provides ongoing security and business continuity protections, including:

Ongoing penetration testing
Cybersecurity awareness training
Endpoint Detection & Response (EDR)
Conditional Access Policies and Identity Protection
Patch management
Immutable data and email backups

The result is a resilient IT environment that allows the company to scale confidently, serve customers efficiently, and rely on technology that has grown with them—supported by a trusted IT partner for more than two decades.
