Perimeter 81

How it happened

Perimeter 81 was an Israeli cybersecurity company offering cloud-based secure network access (SASE/zero-trust), reaching unicorn status with a ~$1B valuation in 2022. As the funding environment tightened, it was acquired by Check Point Software in 2023 for under $500 million, below its peak. Glassdoor reviews from that stretch fit the arc: even amid mostly upbeat notes on the culture, employees described economy-driven pay pressure — softer, below-market compensation — in late 2022, and — after the Check Point deal closed — several longtime staff said the startup feel gave way to a heavier, more bureaucratic corporate environment, with a few remarking the original company had all but faded inside the acquirer.
