Requires Expertise

You can use Expel to get 24/7 managed detection and response (MDR) security coverage from human analysts backed by AI. It monitors your cloud, email, endpoint, identity, and network environments for threats, automatically remediates known attack patterns, and investigates phishing emails. Analysts work directly inside your existing security tools, communicate via Slack or Teams, and provide full visibility into every decision made. Expel reports a 14-minute average time to remediate high and critical incidents.
