What Is Endpoint Security?
Endpoint Security — protecting individual devices — laptops, servers, phones — from threats, since every device is a potential entry point for attackers into the network.
How it works
Endpoint security tools run on the devices themselves: antivirus/anti-malware, host firewalls, and modern EDR (Endpoint Detection and Response) that monitors behaviour, detects threats and enables remote response. As the network perimeter dissolves (remote work, cloud), each endpoint becomes a defended boundary of its own.
Why it matters
Endpoints are where most attacks land — a user clicks a phishing link, a laptop gets malware. Endpoint security (especially EDR) is central to modern SOC operations and analyst work. See malware types for what it defends against.
Frequently asked questions
What is endpoint security?
Protecting individual devices (laptops, servers, phones) from threats using tools like antivirus, host firewalls and EDR — since each device is a potential entry point.
What is EDR?
Endpoint Detection and Response — the modern evolution of antivirus that monitors device behaviour, detects threats, and enables investigation and remote response.
Why is endpoint security important?
Most attacks land on endpoints (a clicked link, an infected file), and with remote work dissolving the network perimeter, each device must defend itself.
