Insights

Managed Detection Expel has launched Managed SIEM and emphasizes co-managed detection with engineers inside customer environments (Microsoft Sentinel and Splunk). This signals a potential sales angle for expanding MDR services, especially for clients using these platforms seeking tighter integration and faster response.

Strong Growth With a revenue range of 500M to 1B and 201-500 employees, Expel demonstrates solid scale and market acceptance in MDR. This positions it as a credible partner for enterprise-grade security initiatives and larger deployments.

Security Validation Recent recognition as a leader by Forrester and Trusted Cloud Provider by CSA boosts credibility. Prospects may be more receptive to Expel’s assurance of security resilience and cloud-native capabilities in complex environments.

Partnership Momentum The introduction of a flexible data lake offering with Sumo Logic shows a willingness to collaborate with data tooling partners. This creates opportunities to co-sell with complementary vendors and address compliance and data storage needs.

Industry Visibility Active participation in RSAC events and a focus on transparent, tool-friendly MDR practices indicate a market-facing growth strategy. This can be leveraged to target customers evaluating modern, non-disruptive security modernization and vendor transparency.
