Our take

Cyber attacks and data breaches are on the rise, particularly at enterprise level, leading to a spike in demand for solutions that offer a 360-degree view of the security landscape. Stellar Cyber offers an open Extended Detection and Response (XDR) platform to automatically detect and nullify risks.

In a bid to unify and optimize all the security tools used by enterprises, Stellar Cyber integrates with existing stacks such as AWS, G Suite, Crowdstrike and Cisco. Since founding in 2015, the company has been on an impressive upward trajectory, receiving multiple awards year after year.

As Stellar Cyber has grown, it has become more focussed on medium-sized businesses with lean security teams. By continually expanding its leadership team and advisory board, and making strong partnerships (such as with AWS), the company seems intent on sustaining its rapid growth.
