Israeli startup Perimeter 81, which offers cloud-based tools to secure networks, raises $100M led by B Capital at a $1B valuation, up from $200M in August 2020
Perimeter 81 said on Monday its backers now value the Israeli cybersecurity company at $1 billion, giving it unicorn status …
Context & Ripple Effects
Perimeter 81's jump from a $200M valuation era — actually August 2020, per the report — to $1B lands it alongside a fast-forming cohort of Israeli cloud-security unicorns: Wiz crossed $1B in March 2021 on its way to $6B by October, and Pentera hit the mark in January 2022 with its K1-led Series C.
The pattern is sector-wide rather than company-specific: later coverage shows Upwind raising at $300M in 2023 and Cyera compounding to $12B by mid-2026, while YL Ventures counted $4B raised across 89 Israeli cybersecurity rounds in 2024. Perimeter 81's round is an early data point in that capital wave.
First-order effects
- Perimeter 81 gains unicorn status and $100M of new capital led by B Capital, giving it five times its August 2020 valuation to spend on competing for cloud network security budgets.
Second-order effects
- Wiz, Pentera, Upwind, and Cyera now face another well-funded Israeli rival selling into the same cloud-security stack, pushing each toward faster product expansion and pricier follow-on rounds to defend their own valuations.
Third-order effects
- If the trajectory holds — Wiz at $6B, Cyera at $12B, national funding doubling year over year — Israeli cloud security consolidates into a small set of mega-valued platforms, with early-stage rounds like the 50 seed deals YL Ventures tallied feeding the pipeline.
The trend: Israeli cloud-security startups are riding a steeply compounding venture cycle, with each unicorn round resetting the valuation bar for the next cohort.
