Ransomware acts at machine speed
Encryption spreads in minutes. Detection and isolation must be automated, not manual.

Endpoint Detection & Response
Continuous visibility into process, file, registry and network activity on every endpoint — with the ability to investigate and contain a compromised device in seconds.
What is EDR?
Endpoint Detection and Response (EDR) is a class of security tooling that records and analyses activity on endpoints — laptops, desktops and servers — to detect malicious behaviour and enable response. Unlike traditional antivirus, which relies primarily on signatures, EDR evaluates what processes actually do: how they spawn, what they write, what they connect to, and how they attempt to persist.
That behavioural focus is what makes EDR effective against ransomware, fileless malware, living-off-the-land techniques and insider misuse. It also provides the forensic record needed to understand an incident after the fact.
Why it matters
Why endpoints remain the front line
Most intrusions still begin on an endpoint — and end there if containment is fast enough.
Fileless and LOLBin attacks evade signatures
Attackers abuse legitimate system tools. Behavioural detection catches what signatures miss.
Investigations need endpoint evidence
Process trees, persistence mechanisms and file lineage are only available if they were recorded.
How it works
How Netralink EDR works
Continuous monitoring with response built in.
- 01
Deploy
Lightweight agents are deployed across workstations and servers, including remote endpoints.
- 02
Record
Process, file, registry, network and user activity is captured continuously to a tamper-resistant store.
- 03
Detect
Behavioural analytics, machine learning and threat intelligence identify malicious activity.
- 04
Triage
Alerts are scored and grouped; automated enrichment provides immediate context.
- 05
Investigate
Analysts trace process lineage, persistence and scope across the estate.
- 06
Respond
Isolate hosts, kill processes, quarantine files and roll back changes where supported.
Capabilities
EDR capabilities
What a mature EDR deployment provides.
Behavioural detection
Detection of malicious process behaviour, not just file signatures.
Ransomware protection
Early detection of mass encryption and shadow-copy tampering, with containment.
Threat hunting
Query and retro-hunt across historical endpoint telemetry.
Forensic timeline
Reconstruct exactly what happened on a host and when.
Automated response
Host isolation, process termination and file quarantine with rollback.
Fleet posture
Visibility of OS versions, patch state, agent health and policy compliance.
In practice
EDR use cases
Ransomware response
Detect and isolate an infected endpoint before encryption spreads to file shares.
Phishing payload investigation
Trace what a malicious attachment or link executed and what it touched.
Server protection
Monitor mission-critical servers for suspicious process and access behaviour.
Remote workforce coverage
Protect endpoints outside the corporate network with cloud-managed policies.
Outcomes
Benefits
- Detection of advanced and fileless threats that signatures miss
- Faster containment of ransomware and compromised hosts
- Forensic evidence for every investigation
- Reduced reliance on periodic scanning
- Foundation for XDR correlation with network and identity signals
FAQ
EDR — frequently asked questions
EDR is security tooling that continuously records and analyses endpoint activity — processes, files, registry and network connections — to detect malicious behaviour and enable investigation and response. It goes beyond signature-based antivirus by evaluating what software actually does.
An agent records endpoint telemetry to a central platform. Detection engines — behavioural rules, analytics and threat intelligence — identify suspicious activity. Analysts use the recorded data to investigate, and response actions such as host isolation are executed from the same console.
In practice, EDR includes antivirus capabilities in most modern deployments. Many organisations run EDR as their primary endpoint protection, replacing standalone antivirus. Where legacy antivirus remains, EDR augments it with behavioural detection and response.
EDR is scoped to endpoints. XDR correlates endpoint telemetry with network, identity, cloud and email signals to detect and investigate threats that span multiple layers. EDR is a core data source for XDR, not a competing category.
Yes. We deploy and tune EDR for your team to operate, or run monitoring, triage and response through our SOC services with agreed escalation paths.
