Endpoint Detection & Response (EDR)
Your employees work from laptops. They connect from home, from hotels, from airport Wi-Fi. They download files, open email attachments, plug in USB drives, and install browser extensions.
Every one of those actions is a potential entry point for an attacker.
Traditional antivirus scans files for known malware signatures. If the malware is new — or if the attack doesn't use malware at all — the antivirus does nothing. And an alarming percentage of modern attacks are fileless. They exploit legitimate system tools like PowerShell, Windows Management Instrumentation, or remote desktop to move through your environment without ever dropping a recognisable malicious file.
Your antivirus can't see what it wasn't designed to look for.
EDR was built for exactly this.
What EDR actually is
EDR — Endpoint Detection & Response — is a lightweight agent that runs on every endpoint in your environment: laptops, desktops, servers, and in some cases mobile devices.
Unlike antivirus, EDR doesn't primarily scan files. It monitors behaviour. Every process execution, every network connection, every registry modification, every privilege change — EDR sees it, logs it, and analyses it against known attack patterns and behavioural baselines.
If a PowerShell process starts at 2 AM, connects to an external IP, downloads a script, and begins enumerating Active Directory — that's not a signature match. That's a behaviour chain that EDR recognises as credential harvesting, and it triggers automated containment: the device is isolated from the network in under a second, the process is killed, and our SOC is alerted for investigation.
This is the difference between watching the front door and watching every room in the building.
How an attack plays out without EDR
Thursday, 22:30 — An employee's laptop is compromised through a malicious browser extension they installed from a third-party site. The extension exfiltrates their browser session tokens silently.
Thursday, 22:45 — Using the stolen session tokens, the attacker establishes a remote command shell on the laptop. They don't need the employee's password — the session token bypasses authentication entirely.
Thursday, 23:10 — The attacker runs a reconnaissance script using native Windows tools. They enumerate every device on the network, every shared drive, every user account. No malware is written to disk. No file is dropped. The antivirus stays silent.
Friday, 00:30 — The attacker pivots to a file server using cached credentials from the compromised laptop. They begin encrypting files. By 06:00, your finance, HR, and operations drives are locked with a ransom demand.
With EDR: The malicious browser extension's outbound connection to an unknown C2 server would have been flagged immediately. The remote shell establishment would have triggered behavioural analysis. The reconnaissance script — even though it used legitimate Windows tools — would have been identified as attack-pattern behaviour. The device would have been isolated from the network within seconds of the first anomalous process chain. Our SOC would have been investigating before the attacker made their second move.
What's included
Agent deployment — Lightweight EDR agents installed across all endpoints. No performance impact. No user disruption. Works on Windows, macOS, and Linux.
Behavioural detection — Continuous monitoring of process chains, network connections, file system changes, and privilege escalations. Detects known malware and unknown threats alike.
Automated containment — Compromised devices are isolated from the network in under one second. The threat is contained before it can spread laterally.
Forensic telemetry — Full device timeline available for incident investigation. Every process, every connection, every file change — logged and searchable. Critical for post-incident analysis and regulatory reporting under GDPR and NIS2.
24/7 analyst response — Every detection is reviewed by our SOC. Automated containment buys time. Human investigation determines the full scope and drives remediation.
Device health scoring — Each endpoint receives a risk score based on its patch level, configuration, user behaviour, and detection history. You see which devices are your highest risk at any given time.
FAQ
"We have 80 laptops. Is EDR overkill?" No — 80 laptops is 80 potential entry points. Attackers don't care how many endpoints you have; they need one. EDR is proportionally more important for mid-sized companies because you likely don't have an internal security team watching for threats. EDR, managed by our SOC, fills that gap.
"Will this slow down our computers?" No. Modern EDR agents consume less than 1–2% CPU and minimal memory. Your employees won't notice it. It runs silently in the background — the only time anyone notices EDR is when it saves the business.
"What happens if an employee's device is isolated?" They lose network access immediately — which stops the threat from spreading. Our SOC contacts you within minutes with a summary of what happened and next steps. In most cases, the device is cleaned and returned to the network within hours. In serious cases, we provide a full forensic report.
