Managed 24/7 response
Layer 3 monitors and investigates alerts around the clock so your team is not staring at a console at midnight.
Endpoint security
Layer 3 EDR
Managed Endpoint Detection and Response
Enterprise-grade endpoint protection for Australian businesses—without building your own 24/7 security operations centre. Layer 3 deploys and manages Layer 3 EDR across Windows, macOS, and Linux: real-time detection, human-led investigation, and active remediation when something genuine shows up.
More than 340 endpoints are under Layer 3 management today. High-confidence detections are validated with minimal false positives—so your team sees real incidents, not alert noise. Pair it with our cybersecurity programme and Layer 3 DNS Guard for defence in depth.

Platform strengths
Managed outcomes, not shelfware
Layer 3 EDR for Australian offices, hybrid teams, and national remote workforces.
Lightweight agent
Low-impact agents on laptops and servers. Layer 3 stages rollout to keep disruption manageable.
Cross-platform coverage
Windows, macOS, and Linux in one programme—important when attackers hop between whatever OS you run.
Human-led remediation
Contain, investigate, and evict threats—not just tickets that sit in a queue until someone has time.
Plain-language reporting
Summaries owners, boards, and insurers can follow without a security engineering degree.
For directors & managers
What enterprise-grade protection looks like in a real office
You do not need to become a security engineer. You need fewer incidents on the floor: ransomware stopped early, hidden access removed, and plain-language reporting when something matters. Here is how Layer 3 EDR shows up for Australian teams.

Real-time detection surfaces high-confidence threats — Layer 3 handles investigation and remediation so your team is not drowning in noise.
Ransomware
Ransomware contained early
Canaries and behavioural rules catch encryption behaviour on one machine. Layer 3 isolates, investigates, and remediates before finance or client folders are locked.
Footholds
Hidden persistence removed
Attackers love legitimate tools and scheduled tasks. Layer 3 EDR finds footholds that basic antivirus never flags as malicious.
Movement
Lateral movement blocked
When someone tries to hop from a laptop to a server or file share, detections fire and spread is cut off while analysts work the incident.
Exposure
Risky credentials surfaced
Admin passwords saved in browsers or scripts on endpoints are a common infostealer target. Layer 3 surfaces them so you can rotate and clean up.
Defender
Defender tuned, not bypassed
Where Microsoft Defender is in scope, Layer 3 manages configs and watches for risky exclusions—so your existing AV investment is not undermined.
24/7 cover
After-hours incidents handled
Most SMBs cannot staff a 24/7 SOC. Layer 3 EDR means high-confidence detections are reviewed and acted on while your office is closed.
Ransomware canaries
Catch encryption before it spreads
Layer 3 EDR watches for early ransomware behaviour on company devices. When a canary trips, the endpoint can be isolated while analysts confirm what happened—before payroll, finance, or client files are locked.

Enterprise-grade
Unmatched protection—managed for Australian business
Detection that keeps up
Behavioural analysis and real-time disruption catch tradecraft that signature antivirus misses—validated alerts with less than 1% false positives on confirmed threats.
Response you can afford
24/7 monitoring and human investigation without hiring a full internal SOC. Layer 3 handles the heavy lifting from first signal through containment.
Built for how you work
Hybrid teams, Microsoft-heavy estates, Hunter and Brisbane on-site support, and national remote coverage. Layer 3 tunes EDR to Australian privacy and insurer conversations.
Capability set
Detection, visibility, and control on every endpoint
From footholds to ransomware canaries—Layer 3 EDR gives owners and managers a clearer picture of endpoint risk.
Persistent footholds
Detect abuse of legitimate apps and processes attackers use to stay hidden on endpoints.
Behavioural detection
Spot malicious process chains and living-off-the-land techniques—not just known malware signatures.
Attack disruption
Real-time disruption impairs attacker tradecraft while analysts confirm and respond.
Lateral movement
Surface stealthy movement between machines before one compromised laptop becomes a site-wide incident.
Ransomware canaries
Early indicators of encryption activity so containment can start before files are lost.
Credential & exposure visibility
Find open ports and risky credentials stored on endpoints before infostealers do.
How it compares
Layer 3 EDR versus common alternatives
Side-by-side highlights against enterprise EDR platforms and DIY alert queues.
Layer 3 EDR vs CrowdStrike FalconFeature table
CrowdStrike is a strong enterprise EDR platform. Layer 3 EDR targets Australian SMBs who want enterprise-grade outcomes with Layer 3 managing deployment, tuning, and 24/7 response—not another console your team never opens.

Frequently asked questions
What is EDR and Managed EDR?
EDR records activity on endpoints—laptops, desktops, servers—to detect suspicious behaviour, investigate incidents, and contain threats. Managed EDR means Layer 3 runs the agents, platform, tuning, and 24/7 monitoring through to remediation. You get outcomes, not another tool to babysit.
Does Layer 3 EDR replace antivirus?
No. EDR sits alongside antivirus and other controls. Layer 3 EDR can also manage Microsoft Defender where that is part of your stack. See how it fits our cybersecurity programme.
Does Layer 3 EDR cover Macs and Linux?
Yes. Layer 3 EDR covers Windows, macOS, and Linux—important when attackers move between whatever systems you run, including hybrid and work-from-home devices.
How does Layer 3 EDR relate to Layer 3 DNS Guard?
They are complementary layers. Layer 3 DNS Guard filters web traffic and categories at the DNS layer. Layer 3 EDR watches what happens on the endpoint itself—processes, persistence, lateral movement, and ransomware behaviour. Most mature programmes use both.
How does Layer 3 deliver Layer 3 EDR?
We scope endpoints, deploy agents, tune detection, and operate 24/7 review and response as part of your security programme. For broader context, start with our cybersecurity services or cybersecurity basics guide.
Is this only for large enterprises?
No. Layer 3 EDR is built for Australian SMBs and mid-market teams who need enterprise-grade protection without building an internal SOC—whether you are in Newcastle, Brisbane, or remote-first nationally.
