What it is

Endpoint security focuses on safeguarding the devices that connect to a company's network—laptops, desktops, servers, smartphones, and even IoT sensors. Modern platforms combine antivirus, behavioral monitoring, disk encryption, device compliance, and automated threat response. Because endpoints are often hit first by phishing, malware delivery, credential theft, and ransomware, this layer forms a critical defense alongside Zero Trust Security principles and external exposure monitoring.

Why it matters

Remote work, BYOD policies, and cloud adoption have dissolved the traditional network perimeter. A single compromised laptop can grant attackers privileged access, enabling lateral movement or a broader Data Breach. Strong endpoint security reduces the likelihood of ransomware outbreaks, prevents unauthorized access to SaaS apps, and creates telemetry for incident response teams to act quickly.

How to reduce risk

  • Deploy modern endpoint protection or detection and response (EPP/EDR) platforms.
  • Enforce full-disk encryption and timely patching of operating systems and applications.
  • Require Multi-Factor Authentication (MFA) or passwordless access for high-risk devices.
  • Segment untrusted devices and limit their reach to sensitive systems.
  • Audit devices regularly for outdated software, risky configurations, or missing agents.
  • Train employees to spot phishing, malicious downloads, and unsafe USB usage.
