Why Professional Services Firms Choose OxygenIT for Cybersecurity
Plenty of companies will sell you security software.
Very few take responsibility for your entire security posture.
OxygenIT is a locally based team of security consultants who work directly with law firms, accounting practices, healthcare providers, engineering consultancies, and growing SMEs. We understand the level of confidentiality required, the regulatory landscape here in NZ, and the impact downtime can have on your clients and revenue.
With us, you’re working with experienced NZ-based experts who know your environment and stay accountable for it.

Local Security Expertise
We are based in New Zealand and support clients across Christchurch, Wellington, and Auckland. If something looks suspicious, we respond quickly.
Industry-Specific Security Strategies
Every industry carries different risks. We design protection around your systems, data sensitivity, and compliance exposure. Nothing is generic.
Rapid Support and Response
Our team isolates suspicious activity and takes action before small issues escalate into major disruptions. We’re deeply committed to protecting your business every day.
Security-First
Best Practices
We align your environment with recognised standards, including ISO 27001, NIST, and the Essential Eight. Your protection follows proven models recognised by auditors and regulators.
OxygenIT Cybersecurity Process
We follow a clear, practical process to strengthen your business step by step. Every decision we make is based on risk, impact, and long-term protection.
Security Risk Assessment
Our team reviews your users, devices, cloud platforms, email systems, firewalls, backups, access controls, and internal policies. From this review, we identify where you are exposed and where a disruption would have the greatest impact on your business.
Test for Vulnerabilities and Weak Points
We scan, test, and pressure-check your systems.
Then we explain the results in plain language to make sure you know exactly what needs attention.
Implement Layered Security Controls
Effective business IT security relies on multiple layers working together.
We strengthen identity management, enforce multi-factor authentication, refine firewall configurations, enhance email filtering, and deploy Endpoint Detection & Response (EDR) to protect devices across your organisation.
Provide Continuous Monitoring and Active Response
Our Managed Security Operations Centre (SOC) and EDR platforms continuously monitor your systems for unusual behaviour. All alerts are reviewed by experienced security specialists who understand what normal looks like in your environment.
If something suspicious appears, we investigate quickly and isolate affected systems if needed.

Frequently Asked Questions
01. What is included in an IT security assessment?
An IT security assessment reviews your systems, users, cloud platforms, email, backups, and access controls. You receive identified risks, prioritised vulnerabilities, compliance gaps, and a practical action plan.
02. How often should penetration testing be done?
Most businesses should complete penetration testing at least annually. You should also test after major system changes, new cloud deployments, or compliance requirements. Regular testing helps uncover new weaknesses before attackers find them.
03. What does EDR protect against?
Endpoint Detection & Response protects devices against ransomware, malware, suspicious behaviour, and unauthorised access. It monitors activity in real time, detects threats early, and isolates affected systems to stop threats spreading across your network.
04. Do you offer fully managed IT security services?
Yes. We provide fully managed IT security services including monitoring, threat detection, response, compliance support, and ongoing improvement. Our team acts as your dedicated security partner, so you are not left managing risk alone.
05. What compliance standards do you support?
We work with ISO 27001, NIST, and the Essential Eight. Our team reviews your current controls, highlights weaknesses, and recommends clear improvements to make sure you are prepared for audits and meet recognised security benchmarks with confidence.
