Microsoft • Cisco • Odoo Partner

Enterprise Services

The systems your business runs on — productivity, ERP, security, servers, and the WAN — engineered and operated by a partner that has run critical infrastructure for two decades.

Microsoft partner. Cisco partner. Odoo partner. One accountable team.

01 — Approach

The Whole Enterprise Stack, One Team

Most organisations buy enterprise IT in fragments — a licensing reseller here, a network contractor there, an ERP vendor somewhere else — and end up owning the integration risk themselves. When the WAN, the identity platform, the ERP, and the security stack are designed by four vendors who never meet, the gaps between them become your outages, your audit findings, and your unbudgeted projects.

HCS approaches the enterprise the way we approach operator networks: as one system. We are a Microsoft partner across the 365 and Azure ecosystem, a Cisco partner for enterprise networking, and an Odoo partner for ERP — which means the team that designs your WAN also understands the tenant riding on it, and the team that customises your ERP knows the identity platform it authenticates against.

The practice areas below stand alone — you can engage any one of them — but they are engineered to fit together, because in production they always do.

02 — What We Deliver

Enterprise Practice Areas

Nine ways we run, secure, and modernise enterprise IT — each deliverable on its own, all designed as one system.

Microsoft PartnerBusiness → E3 · E5 · E7Copilot & Agent 365

Microsoft 365 & Modern Work

The full 365 ecosystem — from Business plans to the E7 Frontier Suite.

As a Microsoft partner we plan, license, deploy, and run the complete Microsoft 365 estate. That spans Business Basic/Standard/Premium for growing organisations, E3 and E5 for the security- and compliance-driven enterprise, and the new E7 Frontier Suite — Microsoft’s first new enterprise tier in a decade, bundling E5, Microsoft 365 Copilot, Agent 365, and the Entra Suite for the agentic, AI-first workplace. We right-size the licensing first, then make the platform actually deliver: identity, device management, security baselines, and adoption.

Licensing strategy and tenant design — Business, E3, E5, and E7 Frontier Suite right-sizing
Tenant-to-tenant and on-premises Exchange migrations with zero-loss cutover plans
Entra ID identity architecture: conditional access, PIM, hybrid join, and the full Entra Suite
Intune endpoint management — Windows, macOS, iOS, Android — with compliance baselines
Microsoft Defender XDR and Purview: threat protection, information protection, DLP, eDiscovery
Microsoft 365 Copilot and Agent 365 readiness, rollout, governance, and adoption programmes
Teams, SharePoint, and OneDrive information architecture that survives real usage
Ongoing tenant operations: secure-score management, licence hygiene, and quarterly reviews

One partner from licence purchase to daily operations — a tenant that is secure, governed, and actually adopted.

Odoo PartnerCustom ModulesERP Migrations

Customised ERP Solutions — Odoo Partner

ERP shaped around how you actually operate — not the reverse.

Generic ERP rollouts fail because they force the business to mirror the software. As an Odoo partner, we do the opposite: we map your real workflows — sales, inventory, manufacturing, finance, HR, field service — and configure, extend, and integrate Odoo around them. Custom modules where the business genuinely differs; standard flows everywhere else, so upgrades stay cheap. And because we build integrations for a living, your ERP talks to your payment rails, your e-invoicing obligations, and your existing systems from day one.

Odoo implementation from discovery to go-live: finance, sales, CRM, inventory, manufacturing, HR, payroll
Custom module development and OWL/QWeb customisation where your process is genuinely different
Migrations from legacy ERP, QuickBooks, Sage, spreadsheets — and Odoo version upgrades
Integrations: M-Pesa and mobile money, banks, KRA eTIMS e-invoicing, e-commerce, and BI stacks
Multi-company, multi-currency, and inter-company flows for regional groups
Self-hosted, Odoo.sh, or cloud deployment with backup, monitoring, and hardening included
User training, change management, and post-go-live support retainers

A single source of operational truth — implemented in weeks-to-months, owned by your team, and built to upgrade.

Zero TrustSOC & SIEMCompliance

Cybersecurity for the Enterprise

Security engineered into the estate — not bolted on after.

Enterprise security fails at the seams: the VPN nobody decommissioned, the admin account outside MFA, the server missing three years of patches. We secure the estate as one attack surface — identity, endpoints, network, cloud, and data — with zero-trust architecture as the design principle and detection-and-response as the operating discipline. Because we also run networks and servers, our hardening survives contact with production.

Security architecture and zero-trust design across identity, network, endpoint, and data
SOC design and SIEM/XDR operations — Microsoft Sentinel, Defender XDR, and open-source stacks
Vulnerability management and penetration-testing programmes with owned remediation plans
Identity security: MFA everywhere, privileged-access management, and admin-tiering
Email security, anti-phishing, and user awareness programmes that measurably reduce click rates
Compliance alignment: ISO 27001, Kenya Data Protection Act, GDPR, PCI-DSS scoping
Incident response: preparation, tabletop exercises, and hands-on response when it matters

A measurably smaller attack surface, watched around the clock, with evidence ready for the auditor.

Windows Server & ADLinuxVirtualization

Systems Administration & Engineering

Microsoft and Linux estates run with operator discipline.

Servers are where enterprise IT quietly decays: undocumented Active Directory sprawl, snowflake Linux boxes, backups nobody has restored from. We bring operator discipline to the server estate — Windows Server and Active Directory engineered properly, Linux fleets automated and reproducible, virtualization platforms sized and patched, and every layer monitored. Whether we run it for you or alongside your team, the standard is the same: documented, automated, and recoverable.

Active Directory design, health remediation, and hybrid Entra Connect environments
Windows Server engineering: clustering, file services, certificates, GPO rationalisation
Linux estate management — Debian/Ubuntu, RHEL — with Ansible-driven configuration
Virtualization: Hyper-V, VMware, and Proxmox migration, sizing, and operations
Patch management and vulnerability remediation across the whole fleet, with maintenance windows that hold
Monitoring and observability: Zabbix, Prometheus/Grafana, and alerting that reaches the right person
Backup engineering with tested restores — because a backup is only real after a restore drill
Automation and scripting: PowerShell, Bash, and Python that removes repeat toil

A server estate that is documented, patched, monitored, and provably recoverable.

Cisco PartnerSD-WANMPLS L2/L3 VPN

Enterprise WAN — SD-WAN & MPLS

Branch connectivity engineered by people who build carrier networks.

The WAN is where enterprise networking meets carrier engineering — and that is exactly where we live. As a Cisco partner with two decades inside operator networks, we design WANs from both sides of the demarc: SD-WAN overlays that blend fibre, LTE/5G, and satellite with application-aware steering, and MPLS L2/L3 VPNs where deterministic performance and privacy still win. We negotiate with carriers in their own language, which changes both the design and the price.

WAN architecture and transport strategy: fibre, microwave, LTE/5G, and LEO satellite blending
Cisco SD-WAN (Catalyst SD-WAN, Meraki) design, deployment, and template-driven operations
MPLS L3VPN and L2VPN/VPLS design — and structured MPLS-to-SD-WAN migrations
Application-aware routing, QoS policy, and per-site SLA definitions that map to the business
Carrier selection and contract negotiation — informed by having built the other side
Secure edge: integrated firewalling, segmentation, and direct-internet-access with SASE patterns
Branch, campus, and data-centre LAN/Wi-Fi engineering to close the last ten metres

Every site on the right transport at the right price, with failover you have actually seen work.

Teams PhonePSTN & SBCContact Centre

Unified Communications & Collaboration

Voice, meetings, and contact centre on one modern platform.

Telephony is now software — but it still has to work like the phone system did. We move organisations from ageing PBXs onto Microsoft Teams Phone and modern UC platforms without losing the numbers, call flows, and reliability the business depends on. From PSTN connectivity and session border controllers to meeting rooms and contact-centre integration, we engineer communications as the production system it is.

Teams Phone deployment: calling plans, operator connect, and direct routing with SBCs
PBX migration and number porting with parallel-run cutovers — no dropped main lines
Auto-attendants, call queues, and business-hour flows built around how calls actually arrive
Meeting-room engineering: Teams Rooms certified hardware, audio/video design, room booking
Contact-centre integration and reporting for sales and support teams
Call quality operations: QoS end-to-end, monitoring, and issue isolation across LAN/WAN

One communications platform — reachable on the old numbers, measurable, and cheaper to run than the PBX it replaced.

Yeastar P-SeriesSIP TrunkingLinkus UC

Yeastar IP PBX & Enterprise VoIP Solutions

Enterprise telephony you own — on-premises, cloud, or hybrid.

For organisations that want full ownership of their phone system, we deploy Yeastar IP PBX platforms — the P-Series appliance, software, and cloud editions — and build enterprise VoIP around them. SIP trunks replace costly analog lines, FXS/FXO and GSM gateways keep legacy handsets and mobile fallback in play, and the Linkus UC clients put the extension on every laptop and phone. Multi-branch networks link into one dial plan, so a four-town operation answers like one company.

Yeastar P-Series deployment: appliance, software edition, or cloud — sized to extensions and call load
SIP trunk provisioning and least-cost routing, with local carrier negotiation
Legacy integration: FXS/FXO and GSM/4G gateways for analog handsets, fax, and mobile failover
Call flows engineered properly: IVR menus, ring groups, queues, time conditions, and voicemail-to-email
Linkus UC clients on desktop and mobile — remote extensions without VPN gymnastics
Multi-site PBX interconnect: branches on one dial plan with centralised management
Call recording, reporting, and CRM/helpdesk integration for sales and support teams
QoS end-to-end and VoIP security hardening: TLS/SRTP, fail2ban, and toll-fraud prevention

A phone system you own and control — enterprise features at a fraction of hosted per-seat pricing.

Under SLA24/7 MonitoringvCIO Advisory

Managed IT & NOC Services

Enterprise-grade IT operations, delivered as a service.

Most organisations cannot justify a full internal IT department with 24/7 coverage — but their business now assumes one. Our managed service puts the operational machinery we built for carrier NOCs behind your enterprise: proactive monitoring, disciplined patching, a real service desk, and an escalation path that ends with senior engineers, not a script. Under SLA, with reporting you can put in front of the board.

Service desk with defined SLAs, ticket ownership, and first-contact resolution targets
Proactive monitoring of servers, network, cloud, and M365 with actionable alerting
Patch and lifecycle management across endpoints, servers, and network equipment
Vendor and ISP management — one throat to choke across your whole supplier chain
Asset, licence, and warranty tracking with renewal planning instead of surprises
Monthly service reporting and quarterly vCIO reviews: roadmap, risk, and budget
Co-managed models that extend your internal team rather than replacing it

Predictable IT spend, measured service levels, and an operations team that scales with you.

Immutable BackupTested FailoverRTO / RPO

Business Continuity & Disaster Recovery

Engineered recovery — with RTO/RPO numbers you have tested.

Every organisation has a continuity plan until the first real disaster finds the gap in it. We engineer continuity backwards from the business: which processes must survive, what recovery time and data loss they can tolerate, and what architecture honestly delivers those numbers. Then we build it — immutable backups, replication, standby capacity — and, critically, we test it, because a DR plan that has never run a failover is a hypothesis, not a plan.

Business impact analysis and honest RTO/RPO targets per system — signed off, not assumed
Backup architecture: 3-2-1-1-0 designs with immutability and air-gapped copies
Replication and standby: cloud DR sites, Azure Site Recovery, and cross-site virtualization failover
Ransomware resilience: isolated recovery environments and clean-room restore procedures
DR runbooks, roles, and communication plans people can follow at 3 a.m.
Scheduled failover and restore drills with timed results reported to management

When the worst day comes, recovery is a rehearsed procedure — not an improvisation.
