Our take
Cybercriminals are now leveraging the power of automation to make the current threat landscape too advanced for a lot of traditional antivirus software. SentinelOne is a cybersecurity company that matches this automation with machine learning-focused software designed to help businesses defend against online attacks.
The company has expanded beyond endpoint security into a broader AI-powered cybersecurity platform spanning endpoint, cloud, identity, and IT operations. This gives SentinelOne access to a larger enterprise market, although it also it also places the company in direct competitions with established cybersecurity leaders, including its biggest rival, CrowdStrike.
As cyberattacks become increasingly automated, the company is expanding its capabilities beyond detection to include AI-driven threat response, helping security teams contain attacks more quickly. While it still trails larger rival CrowdStrike in scale, SentinelOne is investing in platform expansion and automation to compete for enterprises looking to consolidate their cybersecurity into a single solution.
