Pros

Benefits and maybe some office perks

Cons

The product is outdated and far behind the market. Competitors like Proofpoint, Abnormal, and CrowdStrike have out-innovated and outpaced the company. Leadership has no idea how to scale or compete. Acquisitions of weak companies have backfired, dragging performance down. Revenue is shrinking, customers are leaving, and financial targets are consistently missed. Salaries are below market and bonuses are unreliable. The culture is toxic politics and tenure matter more than talent. External hires don’t last. The recent silent layoffs show the company’s real direction. Brace yourself. This is only going downhill.
