IT security: cyber security and antivirus

Cyber security and antivirus services in Christchurch

Antivirus on its own catches known malware after it lands on a device. Managed cyber security adds the layers around it: endpoint protection, email filtering, patching, access policies and a New Zealand team watching the alerts during business hours. We respond to P1 critical issues within 15 minutes during New Zealand business hours.

Why choose OxygenIT for cyber security and antivirus

Every minute unprotected invites trouble. OxygenIT is certified to ISO/IEC 27001:2022, audited annually, and we run the same protection for clients that we run for ourselves.

Threat prevention, not alert watching

We do not sit back and watch alerts flash. Ransomware, data theft and account breaches are hunted and stopped before they gain momentum. Prevention always costs less than recovery.

Business-grade antivirus protection

Hardened antivirus shields endpoints and devices with central control and active monitoring, built for the pace of modern teams.

Continuous threat visibility

You cannot defend what you cannot see. Monitoring runs continuously across every system and user, and suspicious actions are flagged so your staff keep working without disruption.

Ransomware and data breach resistance

Malicious activity is isolated quickly to reduce exposure and keep the business running.

Simple protection for staff

Effective protection should not frustrate your people. Clear policies and simple tools safeguard users without slowing daily work.

A New Zealand team

Engineers in Auckland, Wellington and Christchurch who understand New Zealand business pressures, compliance demands and local threat patterns. When you call, you talk to an engineer who knows your environment.

What our cyber security and antivirus service includes

Layered defence across every system and endpoint.

Advanced endpoint protection

Endpoints remain the most frequent target. Our endpoint detection and response platform watches every device, identifies unusual behaviour and stops attacks before they spread.

Antivirus and anti-malware management

Central antivirus administration keeps workstations and servers up to date and ready.

Ransomware and zero-day threat protection

Adaptive controls and threat intelligence close the gap between discovery and defence. Emerging risks are contained quickly to preserve uptime and data integrity.

Email and phishing protection

Targeted emails are often the first step in an attack. Our email protection service blocks spoofed senders, malicious links and hidden payloads.

Device and user security policies

Consistent standards protect every level of access, with clear policies for passwords, multi-factor authentication and device use across your workforce.

Patch and vulnerability management

Out-of-date software gives attackers a head start. Weaknesses are identified early and updates applied systematically, tested before they are deployed.

Security alerts and incident response

When something looks suspicious, alerts go out and corrective action begins. Early intervention minimises impact and restores stability.

Regular security health reporting

Routine reporting summarises incidents, patterns and overall posture, so leadership can track progress and make better decisions.

Our step-by-step approach to protecting your business

Security works best when every layer supports the next. The process runs from the first assessment through to long-term monitoring and improvement.

Security risk assessment

We start by testing your systems, users and network layers for weak spots, outdated controls and hidden vulnerabilities. A vulnerability assessment gives you the baseline.

Endpoint and system protection setup

Once risks are identified, protection is deployed across endpoints, servers and critical infrastructure.

Policy and access configuration

Access permissions, authentication rules and internal policies are configured to restrict unnecessary access.

Continuous monitoring

Network activity, login attempts and unusual system behaviour are tracked continuously.

Threat response and remediation

Threats are isolated, contained and neutralised, then the path is traced so it cannot happen twice.

Ongoing tuning and reporting

Security does not end with “fixed”. We keep tuning, patching and improving, with metrics that show your protection changing month by month.

How your business benefits from managed cyber defence

Today’s attackers move in seconds, test every gap and never stop. Managed defence detects, denies and dismantles threats before they land.

Prevent costly cyber incidents

Intrusion attempts are exposed early, safeguarding systems, data and reputation.

Reduce downtime and data loss

Tested backup and recovery keeps the business moving when others are still scrambling.

Protect remote and office teams

Your people are everywhere, and so is the protection. Devices, connections and cloud access are locked down wherever your team works.

Skip the in-house overhead

No need to build a security team of your own. Our specialists monitor, respond and strengthen your environment while you stay focused on the business.

Stay audit-ready

Consistent reporting and evidence-driven controls keep you ready for audits, insurers and demanding clients. The honest limitation: our engineers cover New Zealand business hours. After-hours monitoring is a paid add-on delivered by a United Kingdom team, with a genuine uncovered gap between the two that we show you before you sign.

Cyber threats we actively prevent and block

Cyber threats do not knock. One wrong click, one missed patch, and business continuity is on the line. We isolate and neutralise threats across every layer of your environment, including:

  • Malware and ransomware
  • Phishing and email-based attacks
  • Compromised endpoints
  • Suspicious logins and credential abuse
  • Zero-day threats
  • Insider risk indicators

A test to apply to any provider, including us: ask how many accounts have no multi-factor authentication, and when the last patch cycle ran. If the answer is not a number, nobody is checking.

Frequently asked questions

What is the difference between antivirus and cyber security services?

Antivirus software detects and removes known malicious files on a device. Cyber security services take a broader approach, monitoring networks, users, endpoints and systems, identifying suspicious activity early and stopping attacks before they spread across the business.

Is antivirus alone enough to protect a business?

No. Antivirus only detects certain types of malware after they reach a device. Businesses also face phishing, credential theft, ransomware and network intrusions. A full service adds monitoring, endpoint detection and response, system protection and a person who acts on the alerts.

How does your service protect against ransomware?

Continuous monitoring, endpoint protection, patching and vulnerability assessment reduce the chance of a successful attack. Immutable backups and tested restores mean one successful attack does not end the business.

Can you protect remote and hybrid employees?

Yes. Protection extends beyond the office to laptops, cloud platforms and remote connections, with login activity and endpoint behaviour monitored wherever people work.

Will this work with our existing IT systems and software?

Yes. The tools integrate with your current infrastructure, including cloud services, business applications and internal networks. The goal is to strengthen protection while keeping your existing systems running. For the full picture, see our cyber security services for New Zealand businesses.
