Expel has delivered the most value for us through its combination of high-fidelity detection, transparent investigation workflows, and a truly collaborative MDR experience. The Expel Workbench stands out as a core feature. We use it daily to see exactly how alerts are triaged, enriched, and investigated across our integrated tools (Microsoft Defender, Azure AD, email security, etc.). Instead of a black-box SOC, we get clear timelines, analyst notes, and evidence, which significantly improves trust and speeds internal decision-making. From a workflow perspective, Expel has reduced alert fatigue and operational overhead in a very real way. Our team no longer spends hours chasing low-confidence alerts or stitching together context from multiple consoles. Expel’s correlation and enrichment mean that when an issue is escalated to us, it’s already validated, scoped, and prioritized. That alone has saved us dozens of hours per month and allowed our internal staff to focus on higher-value risk reduction work rather than constant reactive triage. One unexpected benefit has been how much Expel improves security maturity over time, not just incident response. Their analysts routinely identify configuration gaps, logging blind spots, and detection opportunities that we wouldn’t have surfaced as quickly on our own. Those insights have directly informed improvements to our controls, tuning decisions, and roadmap. The relationship feels less like “outsourced monitoring” and more like an extension of our security team, which is rare in MDR services. Overall, Expel has provided measurable improvements in response speed, signal quality, and team efficiency, while also raising confidence with leadership by delivering clear, defensible incident narratives when it matters most.

We have had a great relationship with Expel since around October 2023. They filter out stuff that is safe or expected. Expel's admin site is Workbench and is easy to deploy and use. They have a large library of integrations ready to go and adapt to integrations we need. We work with Expel on a daily basis and have not been disappointed.

I love Expel for its excellent Detection and Response capabilities and the ease of device integration, which provides a single pane view. The SOC monitoring and threat hunter teams are outstanding, offering proactive and efficient communication with stakeholders. Setting up Expel was very seamless, and I appreciate that once workbench access was provisioned, we only needed to create custom API keys to integrate our cloud native tools and services. I would definitely recommend their services.
