Our Work

Real delivery across healthcare, energy, finance and public sector estates.

These case studies show where Tesrex has already delivered: secure access, collaboration, contact center, firewall, WAN visibility and Cisco lifecycle control. They show the operating conditions modern AI workflows have to handle: known systems, trusted teams and clear handover.

See how Tesrex has helped teams keep services running, modernise collaboration, contact center service, firewall control, network visibility and Cisco estates.

Customer case studies.

Each story shows a specific operating problem Tesrex helped make easier to run: secure access, collaboration, contact center, firewall, WAN visibility or Cisco lifecycle control.

These are the estates AI workflows have to work inside: real users, real permissions, real platforms and real operational pressure.

Healthcare continuity

Urgent care teams moved remote on the existing Cisco stack.

IC24 kept patient service teams working by extending Webex, Expressway contact center access and secure VPN rather than replacing the platform.

Cisco contact center modernisation

A healthcare contact center route built from agent and supervisor evidence.

IC24 needed more than a platform swap. Tesrex assessed the business and technical gaps, spoke with the people running the service and shaped the Cisco PCCE path.

Network visibility

WAN visibility across every connection type.

Ophir needed one view across satellite, cellular, MPLS, leased line and microwave links; Tesrex proved and rolled out LiveAction monitoring.

Cisco collaboration licensing

Cisco collaboration licensing moved from scattered renewals to one position.

Ophir Energy had Cisco collaboration renewals across countries, currencies and dates. Tesrex reviewed the estate, consolidated licensing and improved renewal control.

Hybrid meeting rooms

One meeting room experience across Teams, Webex and BYOD.

Alantra’s London rooms needed to support client meetings, internal collaboration and flexible joining without making users choose a platform.

Video conferencing assurance

Client meeting quality restored through room and network evidence.

Everest had one-way audio and choppy video in client meetings. Tesrex traced the issue through Webex Room Kit evidence, QoS checks and switchport diagnostics.

Network access control

Global access control without multiplying user friction.

Bausch Health needed one access policy across many sites; Tesrex used Cisco ISE to standardise authentication and authorisation globally.

Cisco firewall modernisation

Cisco firewall control standardised across more than 150 sites.

Bausch Health needed global firewall modernisation. Tesrex deployed Cisco Firepower and NGFW capability with consistent policy, tuning and real-time visibility.

Collaboration modernisation

Collaboration rebuilt from an undocumented legacy estate.

North Somerset Council needed more than a UC upgrade: Tesrex mapped the estate, designed adoption and made remote working practical.

Cisco lifecycle control

One Cisco support position from scattered global renewals.

Medco’s acquisitions left SMARTnet coverage hard to govern; Tesrex normalised the estate into one contract, one cost, one renewal date and one PO route.

What this work proves.

Long before today’s AI workflows, Tesrex delivered in environments where governance, evidence, adoption and operational continuity matter. That experience matters when AI workflows need trusted sources, clean permissions, reviewer confidence and teams who can operate the result.

Proven delivery conditions.

Secure boundaries

Access, VPN, Expressway, Cisco ISE, firewall policy and permission controls.

Estate evidence

WAN telemetry, QoS, licence, support, firewall and lifecycle data.

Adoption under pressure

Healthcare, contact center, meeting rooms, public sector and global handover.

Operable outcomes

An estate, policy, room, review process or contract position people can run.

Why it matters now.

AI workflows depend on the same foundations: clean sources, safe permissions, reviewer confidence, platform evidence and teams that trust the handover.

  • Trusted sources
  • Clean permissions
  • Reviewer confidence
  • Platform evidence
  • Team handover

Bring us the messy estate, platform or workflow.

We will map the estate, source material, reviewers and first practical move for improvement.
