Your Remote Workers Are Your Biggest Security Risk. Here's How to Fix That.

Every device that connects to your network from outside the office is a potential entry point for attackers. Consumer-grade home routers with default passwords. Personal laptops running outdated software. Employees switching seamlessly between coffee shop Wi-Fi and the corporate network without a second thought. For small and midsize businesses that supported hybrid work for the first time in recent years — often standing it up quickly and under pressure — these aren't hypothetical risks. They're the daily reality of how your team works.

The problem is that most SMBs secured the office and then tried to extend that security to remote workers as an afterthought. A VPN here, a web filter there. The result is a patchwork that leaves gaps attackers are trained to find — particularly the risk of malware that enters through a compromised remote device and moves laterally through the network before anyone notices.

Fortinet's endpoint and work-from-anywhere user protection framework is built to close those gaps completely, with a unified approach that covers every device, every user, and every location from a single integrated platform.

Why VPNs Alone Are No Longer Enough

VPNs have been the default remote access tool for decades, and they do one thing well: they create an encrypted tunnel between a remote device and the corporate network. The problem is that once a device is inside that tunnel, a traditional VPN extends implicit trust to everything on that device — including any malware that hitched a ride.

In a hybrid workforce, where employees move fluidly between remote and on-site work, this lateral movement risk is compounded. An infected device that connects remotely can carry threats into the corporate network, and from there they spread. Ransomware in particular is devastatingly effective at exploiting this path — encrypting files across shared drives and networked systems before the security team even knows something is wrong.

Zero Trust Network Access (ZTNA) is the modern answer to this problem, and it works on a fundamentally different principle: never trust, always verify.

Zero Trust Network Access with FortiClient

FortiClient is Fortinet's unified endpoint agent, and ZTNA is at the heart of what it delivers. Rather than granting blanket network access once a user authenticates, ZTNA verifies identity and device posture on a per-session basis — and grants access only to the specific application or resource the user needs, nothing more.

This least-privilege approach dramatically shrinks the attack surface. A compromised device can't reach systems it has no business accessing. A stolen credential can't be used to move laterally through the network. And if a device is determined to be compromised mid-session, access can be revoked in real time.

From the user's perspective, ZTNA actually improves the experience. There's no manual VPN configuration, no backhauling of all traffic through a central server that slows down cloud application access, and single sign-on means users authenticate once to reach any authorized application from any location. It's a more secure experience that also happens to be faster and simpler.

FortiClient integrates natively with the Fortinet Security Fabric, managed directly through the FortiGate NGFW or via the FortiClient Endpoint Management Server (EMS). This means administrators get full endpoint telemetry — logged-in user identity, running applications, unpatched vulnerabilities — without deploying separate management infrastructure.

Endpoint Hygiene: Vulnerability Scanning and Auto-Patching

One of the most consistently exploited attack vectors against SMBs is unpatched software. Attackers know that large organizations have formal patch management programs. They also know that smaller organizations often don't — and they target known vulnerabilities in unpatched endpoints systematically.

FortiClient addresses this with automated vulnerability scanning and patching that runs continuously, even when the endpoint is offline. Risk-based conditional access rules allow administrators to enforce patching compliance as a condition of network access — so a device that hasn't applied critical patches can be blocked from connecting until it does. An application inventory provides visibility into every piece of software running across managed endpoints, flagging outdated applications where patches may no longer be available and identifying potentially unwanted software that increases risk.

Web filtering policies are enforced by FortiClient on and off the network, ensuring that users can't browse to malicious sites regardless of whether they're behind the corporate firewall or working from a hotel. This eliminates the need for separate web proxy tools or third-party web filtering solutions — everything is managed through the same unified policy engine.

Two-Factor Authentication with FortiToken Cloud

Credential theft is one of the most common initial access vectors in SMB breaches. Phishing emails, password reuse from breached sites, and social engineering all yield credentials that attackers use to log in as legitimate users — bypassing most security controls entirely because they appear to be authenticated.

FortiToken Cloud adds two-factor authentication (2FA) to the remote access workflow, making stolen credentials worthless on their own. Even if an attacker has a valid username and password, they can't complete authentication without the second factor. FortiToken Cloud supports both physical tokens and mobile push authentication — users validate login attempts with a single tap on their smartphone — and administrators can provision, manage, and revoke tokens from anywhere with internet access.

Real-Time Breach Protection with FortiEDR

Traditional antivirus tools detect known malware by matching signatures. Against novel ransomware variants, zero-day exploits, and living-off-the-land attacks that use legitimate system tools maliciously, signature-based detection is increasingly ineffective.

FortiEDR (Endpoint Detection and Response) takes a different approach. Rather than relying solely on known-bad signatures, FortiEDR uses machine learning and patented code-tracing technology to detect malicious behavior in real time — blocking exploits and stopping breaches as they happen, not after the fact.

What sets FortiEDR apart for SMBs is its post-infection protection layer. FortiEDR is designed to protect endpoints even if they are already infected — controlling outbound communications to cut off command-and-control connections, preventing file system modifications to stop ransomware encryption, and blocking lateral movement so threats can't spread. If a breach does occur, FortiEDR's automated incident response capabilities can roll back malicious changes and restore systems to their pre-attack state, eliminating the need to reimage infected devices. For a small IT team without the resources for a full forensic investigation, this automated remediation capability is practically invaluable.

Automated Threat Intelligence with FortiSandbox Cloud

When a new threat appears in the wild — a new ransomware strain, a novel phishing technique, an unknown malware variant — the window between first sighting and widespread exploitation can be hours. Organizations that rely on manual threat feed updates or monthly signature pushes are perpetually behind.

FortiSandbox Cloud is a Platform-as-a-Service sandboxing solution that analyzes unknown files and URLs in an isolated environment using dual machine learning models, then automatically distributes threat intelligence updates across the entire Fortinet Security Fabric in minutes. Unlike many sandbox SaaS solutions that cap submission volumes, FortiSandbox Cloud offers unlimited submissions — so high-traffic environments don't face throttling that creates blind spots.

Threat analysis is mapped to the MITRE ATT&CK framework and produces STIX 2.0 compliant indicators of compromise, making the intelligence immediately actionable for security operations and compatible with external threat intelligence platforms.

A Framework Built for SMB Reality

The five components — FortiClient ZTNA, FortiToken Cloud 2FA, FortiEDR breach protection, FortiSandbox Cloud threat intelligence, and FortiGate NGFW — aren't separate products that need to be integrated manually. They operate as a cohesive framework within the Fortinet Security Fabric, sharing threat intelligence automatically and reducing the analysis burden on administrators who are managing security alongside every other IT responsibility.

For SMBs, this integration is the practical difference between a security posture that actually works and one that looks good on paper but fails under pressure. When the FortiEDR agent detects a new threat behavior on an endpoint, FortiSandbox analyzes it and pushes updated signatures to every protected device. When FortiGate identifies a compromised IP in network traffic, FortiClient can enforce real-time access revocation. The platform responds as a system — not as a collection of disconnected tools.
