OneLayer Taps Tamar Tsuk Perez as Product Head

The Private 5G Gold Rush: Why OneLayer’s New Product Chief Could Be the Sheriff This Town Needs
The private LTE/5G network space is starting to look like the Wild West—minus the tumbleweeds and with way more firewalls. Enterprises from factories to oil rigs are stampeding toward private cellular networks, lured by promises of bulletproof security and industrial-grade connectivity. But here’s the rub: more networks mean more attack surfaces, and somebody’s gotta play sheriff. Enter OneLayer, a specialist in locking down these digital frontiers, which just deputized cybersecurity veteran Tamar Tsuk Perez as its new Head of Product Management.
This isn’t just corporate musical chairs. Private LTE/5G deployments are projected to balloon to $8.4 billion by 2026 (ABI Research), and every dollar of that growth comes with a target on its back. Hackers love nothing more than an unpatched IoT sensor or a misconfigured network slice. OneLayer’s bet? That Perez—a specialist in operational technology (OT) security—can turn their asset management tools into the equivalent of a bank vault for Industry 4.0.

Why Private Networks Are the New Corporate Battleground

Forget about your smartphone’s spotty 5G coverage—we’re talking about private cellular networks built like Fort Knox. Manufacturers are wiring up factories with 5G-connected robots, utilities are monitoring grids with LTE-enabled sensors, and ports are automating cranes that talk over dedicated spectrum. These aren’t nice-to-haves; they’re critical infrastructure.
But here’s the catch-22: The very things that make private networks powerful (low latency, localized control) also make them juicy targets. A ransomware attack on a 5G-enabled auto plant could halt production lines faster than a union strike. Energy companies? One breached substation could black out a city. Traditional IT security tools often flop in these environments because OT devices—think PLCs or SCADA systems—weren’t designed with Wi-Fi passwords in mind.
This is where OneLayer’s tech stack comes in. Their platform acts like a bouncer for private networks, verifying every device (Is that *really* a valid crane controller or a hacker’s spoofed node?) and segmenting traffic like prison blocks. With Perez steering product strategy, expect sharper tools for threat detection and automated policy enforcement—because nobody’s got time to manually approve 10,000 IoT thermostats.

Tamar Tsuk Perez: The OT Whisperer Takes the Wheel

Perez isn’t some fresh-faced MBA with a buzzword bingo card. Her resume reads like a threat actor’s nightmare: stints in OT security at companies where “downtime” means million-dollar losses, not just buffering Netflix. In the private network world, that’s gold.
Most cybersecurity pros speak “firewall” or “endpoint detection.” Perez speaks “modbus” and “HMI vulnerabilities”—the lingua franca of industrial systems. At OneLayer, her challenge is twofold:

Corporate IT teams love zero-trust frameworks. Factory floor managers? They’d rather swallow a wrench than deal with authentication pop-ups on a welding robot. Perez’s playbook will likely focus on “invisible” security—policies that run silently in the background without requiring a Ph.D. in network topology to operate.

As 5G matures, enterprises will carve up their private networks into “slices” (dedicated virtual segments for different tasks). A hospital might run patient monitors on one slice and HVAC systems on another. Perez’s team will need to ensure OneLayer’s tools can police these slices without becoming a bottleneck.

The Bottom Line: Security as a Growth Engine

OneLayer’s Perez hire isn’t just about keeping hackers out—it’s about cracking open new markets. Industries like mining and logistics, which have been slow to digitize (ever tried getting LTE signal underground?), will only commit to private networks if security isn’t an afterthought.
Competitors like Palo Alto Networks and Cisco are elbowing into this space, but they’re often retrofitting tools built for office Wi-Fi. OneLayer’s edge? A product suite born in the industrial trenches, now with a leader who knows how to armor-plate it.
The private 5G gold rush is on. And if Perez plays her cards right, OneLayer won’t just be selling shovels—they’ll be writing the rulebook for how this town runs.
Case closed, folks. Now, if only someone could fix public 5G coverage in midtown…
