About Us

Experts in Cybersecurity, Microsoft 365, and Cloud IT Solutions Since 2010

We specialise within the Investment industry, with a sizable chunk of our customers within this vertical. In recent years, we have expanded our clientele to include operators of critical national infrastructure and charities (through our Modalit brand).

We understand that these businesses are a prime target for cybercriminals. The large pool of funds and plethora of sensitive information that they hold is enough motivation for any cybercriminal. Our solutions are specifically designed to empower our customers to identify cyberthreats and keep their businesses safe.

At Tivarri, we provide secure, scalable, and intelligently managed IT platforms designed to meet the needs of modern, security-conscious organisations. We recognise that every business is different — and so is every IT environment. Our team works closely with yours to understand your goals, compliance needs, technical constraints, and growth plans. Whether you’re a small professional services firm or a growing development team, we provide the tools, licensing, infrastructure, and support to help you thrive securely and efficiently.

We offer a wide range of solutions. From advanced Microsoft 365 configurations to virtual desktop solutions hosted in either Microsoft or our own UK data centres. With 15 years of experience supporting highly regulated industries, we deliver flexible, compliance-ready solutions tailored to each client.

Tivarri Modern Desktop

Tivarri Modern Desktop combines the flexibility of Microsoft 365 with enhanced security and compliance features. It enables staff to work anywhere, with local PC performance, secure cloud storage, and offline access that synchronises when back online — a perfect balance of productivity and compliance.

Windows 365 Enterprise Cloud

Windows 365 Enterprise Cloud is Microsoft’s fully managed Cloud PC service. Each user gets their own virtual desktop, hosted entirely in Microsoft’s global data centres with no local data storage. It is simple to deploy, easy to scale, and regulator-approved by design.

Tivarri Hosted Desktop

Tivarri Hosted Desktop is a private cloud solution hosted in secure UK data centres. It delivers enterprise-class performance with flexible resource allocation and is trusted by regulated firms that require maximum security, compliance, and control over their IT environment.

Tivarri VDI

Tivarri VDI offers unmatched performance and flexibility for demanding workloads. Hosted in UK data centres, it removes hardware limits by allowing desktops to scale up to 128 vCPUs and 384 GB RAM. With transparent pricing and expert support, it is ideal for finance, engineering, research, and other data-intensive industries.

We know Your IT Challenges

At Tivarri, we understand and appreciate the system requirements of businesses like yours. We understand the role that IT plays in your organisations and the potential consequences of IT disruptions. You need complete system reliability; full system compliance, especially with GDPR and FCA regulations; prompt responsive support if things go wrong and the ability to share work and run complex integrated applications such as Bloomberg Professional or Refinitiv Eikon, Tradar and Intelliflo alongside Microsoft Office.
