Safeguard operational records with immutable and isolated backups, comprehensive business and Microsoft 365 backup, and redundant secure cloud backup repositories.

We enforce strict credential standards and secure data handling procedures to prevent unauthorized lateral movement within your business environment.

Includes routine backup testing, simulated restoration exercises, and documented recovery planning so your staff resume work without critical operational delays.

Microsoft 365 Security

Systematic Tenant Hardening & Governance

Default cloud settings frequently leave pathways open to data exposure. We harden Exchange, SharePoint, OneDrive, and Microsoft Teams to eliminate uncontrolled external sharing and restrict sensitive file distribution across your team.

Our posture reviews audit tenant permissions, enforce least-privilege administrative roles, activate unified audit logging, and align configurations with proven baselines for small business cyber security.


Harden Exchange Online, Teams, SharePoint, and OneDrive configurations. We audit external sharing links, lock down guest permissions, and verify continuous audit logging.

Targeted baseline configurations that neutralise threats before they compromise workstations or disrupt local business operations.

Entra ID & Access Controls

Defender & Endpoint Security

Email & Office 365 Security

Enforce Conditional Access, mandatory MFA, legacy-authentication blocks, and trusted device controls. We configure emergency break-glass administrative accounts and apply risk-based sign-in policies where licensed.

Deploy Microsoft Defender for Business and Endpoint Protection Services with Antivirus, EDR, Attack Surface Reduction (ASR) rules, Tamper Protection, and resilient Ransomware Protection New Zealand businesses rely on.

Protect collaboration with Defender for Office 365 and Email Security Services. We configure Safe Links, Safe Attachments, anti-phishing filters, real-time alert triage, and systematic Secure Score remediation.

Endpoint & Alert Oversight

Proactive Microsoft Defender health checks, suspicious sign-in evaluations, device configuration profiles, and continuous policy maintenance for team fleets.

Defender Endpoint and Email Security Services

Integrated threat suppression protecting daily communications and local devices against zero-day exploits, evasive phishing payloads, and destructive ransomware threats.

Defender for Business & EDR

Defender for Office 365

Domain Hygiene: SPF, DKIM, DMARC

Equip workstations with Endpoint Detection and Response (EDR), next-generation antivirus, Attack Surface Reduction (ASR) rules, web content filtering, and Tamper Protection.

Neutralise malicious messages before they arrive using Safe Links click-time verification, Safe Attachments sandboxing, and intelligent anti-phishing threat inspection.

Configure and supervise correct DNS authentication records to preserve outgoing domain reputation, halt executive impersonation, and prevent fraudulent email delivery.

Alert Investigation & Remediation

Microsoft Secure Score Tuning

DLP & Advanced Governance

Specialist-Partner Solutions

Routine analysis of incoming security telemetry, prompt incident investigation, and active remediation to address configuration drift and newly discovered vulnerabilities.

Structured posture reviews measuring tenant security benchmarks against real-world risk, systematically closing configuration gaps without disrupting operational productivity.

Implementation of Data Loss Prevention (DLP) policies to detect sensitive personal records, tax information, and business-critical intellectual property across cloud repositories.

Where advanced operational mandates apply, we facilitate suitable solutions including SIEM log centralization, dedicated MDR capabilities, and accredited third-party penetration testing.

Security Monitoring & Threat Detection

Comprehensive business cyber security Wānaka organisations count on for real-time visibility across laptops, workstations, network switches, and critical user accounts.

Event Monitoring & Alerts

Investigation & Remediation

Continuous endpoint and event monitoring engineered to flag suspicious activity, failed-login detection, brute-force indicators, and anomalous connection attempts.

Direct threat investigation and response, active malware remediation, structured incident escalation, and ongoing configuration tracking across all managed seats.

Centralised alerts ensure critical notifications are triaged swiftly rather than overlooked in noisy inbox notifications or unmanaged system logs.

Regular security policy reviews and actionable summary reporting provide your leadership team with clear oversight of network health and emerging risks.

Vulnerability Management & Security Assessments

Identify overlooked weaknesses before attackers exploit them. Our assessments evaluate your network perimeter, account hygiene, and productivity suites against baseline standards.
