Illusive Networks, which aims to stop cyberattacks using deceptions on endpoints like IoT devices, raises $24M Series B1, bringing its total raised to $54M+

Context & Ripple Effects
Illusive Networks' $24M Series B1 lands in a niche where venture money has been accumulating quietly: TrapX raised an $18M Series C last year for the same core idea of stopping attackers with decoys rather than signatures, and both now sit around the $50M+ raised mark. The difference is Illusive's focus on endpoints like IoT devices, where traditional network perimeter tooling has least visibility.
The round also fits alongside adjacent bets on rethinking enterprise network defense from the inside out — Edgewise Networks' machine-learning microsegmentation raise and Elisity's AI-powered monitoring and access control round all attack the same assumption that firewalls and edge appliances are sufficient.
First-order effects
- Illusive gains capital to scale its endpoint-deception product toward IoT-heavy deployments, directly competing with TrapX's decoy databases and workstations for the same security budgets.
- Enterprise buyers evaluating deception technology now have two well-funded vendors at comparable funding levels, turning what was a novel category into a competitive procurement decision.
Second-order effects
- Vendors in neighboring approaches — microsegmentation (Edgewise), AI monitoring and access control (Elisity) — face pressure to show their tools complement rather than duplicate deception layers, since CISOs consolidating spend will force the comparison.
- Deception vendors' push into IoT endpoints pulls them into operational-technology accounts where device diversity is high, raising the bar for platforms that can fake believable assets across heterogeneous fleets.
Third-order effects
- If deception proves viable at IoT scale, enterprise security architecture shifts further from perimeter-centric stacks toward layered interior defenses — detection by misdirection layered over segmentation and behavior analytics as standard practice.
- Sustained VC funding across TrapX, Illusive, Edgewise, and Elisity points toward eventual consolidation, with larger security platforms likely acquiring point solutions rather than building deception capability in-house.
The trend: Enterprise security spending is migrating inward from the network perimeter toward endpoint-native techniques — deception, microsegmentation, and behavioral analytics — as IoT expands the attack surface beyond what edge defenses can see.
