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.

Palo Alto NetworksEach 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.
IC24 kept patient service teams working by extending Webex, Expressway contact center access and secure VPN rather than replacing the platform.
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.
Ophir needed one view across satellite, cellular, MPLS, leased line and microwave links; Tesrex proved and rolled out LiveAction monitoring.
Ophir Energy had Cisco collaboration renewals across countries, currencies and dates. Tesrex reviewed the estate, consolidated licensing and improved renewal control.
Alantra’s London rooms needed to support client meetings, internal collaboration and flexible joining without making users choose a platform.
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.
Bausch Health needed one access policy across many sites; Tesrex used Cisco ISE to standardise authentication and authorisation globally.
Bausch Health needed global firewall modernisation. Tesrex deployed Cisco Firepower and NGFW capability with consistent policy, tuning and real-time visibility.
North Somerset Council needed more than a UC upgrade: Tesrex mapped the estate, designed adoption and made remote working practical.
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.
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.
Access, VPN, Expressway, Cisco ISE, firewall policy and permission controls.
WAN telemetry, QoS, licence, support, firewall and lifecycle data.
Healthcare, contact center, meeting rooms, public sector and global handover.
An estate, policy, room, review process or contract position people can run.
AI workflows depend on the same foundations: clean sources, safe permissions, reviewer confidence, platform evidence and teams that trust the handover.
We will map the estate, source material, reviewers and first practical move for improvement.
