Israeli cybersecurity unicorn Perimeter 81 laid off 20 employees in December 2022, representing 8% of its then 250-person workforce. The company, which had reached a $1 billion valuation just six months earlier after raising $100 million, cited the need for business efficiency and productivity amid a broader economic downturn as the reason for the restructuring. Founded in 2018 and headquartered in Tel Aviv, the startup develops Security Service Edge and Zero Trust Network Access solutions.
