Cato Networks, which offers a cloud-based security service that protects remote workforces, raises $77M led by Lightspeed Venture Partners
Cato Networks has raised $77 million in venture capital as the company expands the reach of its cloud-based security service.
Context & Ripple Effects
This $77M round is the second act in a Lightspeed-led funding ladder: the firm had already led Cato's $55M round in January 2019 when the company was still framed as a software-defined wide-area networking vendor, and this raise marks the pivot in its public positioning toward cloud-delivered security for remote workforces — timed a week into widespread lockdowns. A year later the same backers would lead a $130M Series E at a $1B+ valuation, confirming the thesis.
The round also fits a broader Lightspeed pattern in Israeli cybersecurity: days earlier the firm led Axonius's $58M Series C, making Cato one of two security bets the firm concentrated capital into within the same month.
First-order effects
- Cato gains fresh capital to expand the reach of its cloud-based security service at the exact moment remote work is driving enterprise demand, with Lightspeed doubling its stake in a company it has backed since 2019.
Second-order effects
- Competitors selling perimeter-based or on-premises security now face a rival with fresh funding and a remote-workforce-native pitch, while Lightspeed's parallel Axonius investment builds it an interconnected Israeli security portfolio.
- The networking-to-security repositioning pressures pure SD-WAN vendors to bolt on security or cede the converged category to Cato's model.
Third-order effects
- The pattern held: successive rounds took Cato from this $77M raise to a $359M Series G at a $4.8B+ valuation with total funding past $1B — evidence that pandemic-era remote work permanently re-rated cloud-delivered network security, and that repeat lead investors capture compounding value by funding the same winner across rounds.
The trend: Enterprise security capital is consolidating around cloud-delivered platforms for distributed workforces, with repeat lead investors like Lightspeed doubling down round after round.
