managed security services

Layer3’s managed security shields every user, device, and cloud workload with one coordinated service. A single lightweight agent feeds live telemetry to our New Zealand SOC where qualified analysts watch alerts round-the-clock, isolate risky accounts in minutes, and close the loop with clear board-ready reports. Continuous vulnerability scans and policy checks run quietly in the background so issues are fixed before they become incidents.

Four Pillars of Protection

Threats hit from every angle, so our service is built in layers. Endpoint & Server Protection stops malware at the device, Secure Access Edge travels with users anywhere they work, Cloud SIEM & SOAR turns millions of log lines into instant answers, and MXDR adds human eyes for incidents that need expert judgement. Together they give you one coordinated defence and a single source of truth for security posture.

ENDPOINT & SERVER PROTECTION

AI-driven protection blocks ransomware, file-less attacks, and zero-days across Windows, macOS, and Linux. Behaviour analytics prevent threats before they detonate, while rich telemetry speeds root-cause analysis

Stops Modern Ransomware & Malware

Behaviour models update in real time, blocking new strains the moment they appear.

Instant alerts to our security team

We’re notified the moment something looks suspicious, so issues are handled before they disrupt work

Catches File-less & Memory-Only Attacks

Specialised memory monitoring finds threats that never write to disk and slip past legacy antivirus.

Detailed activity history for quick investigations

Secure logs let us trace exactly what happened and respond with confidence.

Covers every company device, everywhere

Desktops, laptops and servers all get the same round-the-clock protection, whether staff are in the office or remote.

Clear security snapshot

A simple report shows what was blocked and how healthy your devices are perfect for board updates or audits.

SECURE ACCESS EDGE (SASE)

Zero-trust tunnels, encrypted DNS, and identity-aware policies follow each user wherever they work. Traffic is routed through Layer3’s cloud edge, enforcing device-health and content rules in real time while shrinking the attack surface.

Same Secure Network, Everywhere

Staff appear on the corporate LAN no matter where they sign-in - no risky split tunnels.

Built-in Intrusion Prevention

Known exploits and C2 traffic are stopped in-line before they ever reach an endpoint.

“Portable Firewall” Protection

The edge client brings IPS, web filtering and malware blocking to every café Wi-Fi.

SaaS Policy Enforcement

Allow, read-only or block each cloud app by user, device posture or location.

Deep SSL / TLS Inspection

Encrypted traffic is safely unwrapped, scanned and re-encrypted without slowing users down.

Secure Remote Access to HQ Apps

Users launch internal apps through the edge, no inbound ports or legacy VPNs required.

CLOUD SIEM & ANALYTICS

We stream telemetry from every layer of your stack - endpoints, Microsoft 365, Azure AD, firewalls, SaaS and optional email-security feeds - into a cloud SIEM that correlates events in real time. When it spots a threat (e.g. a compromised mailbox, impossible-travel sign-in, or stolen authentication token) it auto-opens a case, enriches it with context, and triggers SOAR playbooks that can lock the account, isolate the device or block the IP in seconds. With the MXDR upgrade, our 24x7 response team is notified immediately and drives the incident to resolution.

Compromised-Account Detection

Flags password spray, OAuth token theft and risky sign-ins the moment they occur.

Automated SOAR Response

Playbooks quarantine hosts, disable accounts and spin up MFA resets - no human delay.

Conditional-Access & Geo Alerts

Identifies log-ins from new countries or bypassed policies and blocks them automatically.

Case Management & MXDR Handoff

Every alert becomes a case with timeline, impact and evidence; MXDR analysts step in if subscribed.

Full Microsoft 365 Visibility

Audits email rules, file activity and admin changes across Exchange, SharePoint and Teams.

Compliance-Ready Audit Trail

12-month hot search with up to 7-year archive meets NZISM, PCI and ISO requirements.

MANAGED DETECTION & RESPONSE (MXDR)

Every SIEM case routes straight to our New Zealand based security operations centre, where certified analysts watch alerts round-the-clock. Using the same playbooks that power our automated SOAR actions, the team triages, contains and eradicates threats, then guides you through remediation and future hardening.

24 × 7 Eyes-on-everything

High-severity cases are reviewed within minutes - never the next business day.

Root-Cause Forensics

Timelines reveal how the incident began, what it touched, and how to prevent a repeat.

Rapid Remote Containment

Analysts can isolate a device, block an IP, or disable an account before damage spreads.

Board-Ready Closure Report

Plain-English summary, impact assessment, and next-step recommendations follow every event.

Human-Led Threat Hunts

Proactive searches uncover stealthy attackers that automation alone might miss.

Continuous Improvement Loop

Lessons learned feed back into policies and playbooks, steadily hardening your environment.
