Description
Fortinet FortiClient is a unified endpoint agent that converges secure connectivity, endpoint protection, and advanced threat detection into a single lightweight client. It acts as a Fabric Agent within the Fortinet Security Fabric, providing deep visibility and control across every endpoint.
Key Capabilities
- ZTNA & Secure Remote Access — Delivers zero-trust network access and VPN-encrypted tunnels with multi-factor authentication (MFA), posture checks, and ongoing device verification.
- Endpoint Protection — AI-based next-generation antivirus (NGAV), behavior-based anti-exploit, ransomware protection, application firewall, and USB device control.
- Web Filtering & CASB — FortiGuard-powered URL filtering across 75+ categories, plus cloud access security broker controls for shadow IT visibility.
- Vulnerability Management — Automated vulnerability scanning, software inventory tracking, and flexible patching to reduce attack surface.
- Sandbox Integration — Natively integrates with FortiSandbox to block never-before-seen files and submit suspicious samples for real-time analysis.
- Central Management — Deployed and configured via FortiClient EMS (on-prem or cloud) with role-based access control, Active Directory integration, and centralized logging and reporting.
Editions
FortiClient is available in several editions — VPN/ZTNA Edition, EPP/APT Edition, and Chromebook Edition — each tailored to different organizational needs while sharing a common agent framework.
Highlights
Pros
- Unified single-agent architecture combines ZTNA, VPN, web filtering across 75+ categories, CASB, and endpoint protection — eliminating the need for multiple separate endpoint agents.
- Deep integration with the Fortinet Security Fabric enables real-time telemetry sharing between endpoints, FortiGate firewalls, and FortiSandbox for automated threat response and dynamic access control.
- Natively integrates with FortiSandbox to block never-before-seen files and automatically submit suspicious samples for real-time analysis, preventing zero-day threats.
- AI-based next-generation antivirus (NGAV) with behavior-based anti-exploit and ransomware protection achieved a 100% block rate for exploits and unknown threats in NSS Labs testing with zero false positives.
- Named a Gartner Peer Insights Customers' Choice for Endpoint Protection Platforms for four consecutive years (2023–2026) with a 4.8/5 rating and 98% willingness to recommend.
- Centralized management via FortiClient EMS provides a single-pane-of-glass dashboard for vulnerability scanning, software inventory, compliance monitoring, and automated patching across all endpoints.
Cons
- The agent can consume significant CPU and memory resources, which may noticeably slow down performance on older or lower-spec endpoint devices.
- Web filtering can be inconsistent on HTTPS sites, and enforcing web filter rules on encrypted traffic requires installation of a separate web filter plugin.
- Analytics and reporting lack deeper trend analysis and vulnerability prioritization, flagging all issues uniformly without categorizing severity levels.
- Frequent version updates can cause compatibility issues across endpoints, often requiring IT teams to manually reinstall newer versions on affected devices.
- The VPN connection can occasionally drop and interrupt active sessions, and diagnosing connectivity problems is reportedly difficult for administrators.
- The user interface is highly technical, making it less accessible for non-IT staff to understand and navigate without specialized training.
