Our take
Cybercriminals are now leveraging the power of automation to make the current threat landscape too advanced for a lot of legacy antivirus software. SentinelOne is a cybersecurity company that matches this automation, with machine learning-focused software that is built to help businesses battle online attacks.
The company expanded the scope of its business from the endpoint security market to three markets valued at a combined $30 billion, including the corporate endpoint security and IT operations management markets. This gives SentinelOne a bigger potential customer base, although also puts them in direct competition with more focused cybersecurity companies, in addition to its biggest competitor, CrowdStrike.
When the company went public, it made financial headlines as the highest-valued cybersecurity IPO ever, which gave SentinelOne a market cap of $10B, though it's now fallen to around $4B. It has subsequently launched S Ventures, a $100M fund, through which SentinelOne invests in cybersecurity startups and has expanded its partnership with major tax firm KPMG to accelerate cyber investigations and responses to threats.
