Benefits

Improved Cloud Defense Posture
By implementing Active Cloud Defense Resilience blueprint, LTM solution ensured timely detection of shadow IoAs and IoCs, prevention from critical threats with Active Threat Hunting capability coupled with secured Data Lake, protected client endpoint, identity, O365, application, Azure AD with Microsoft Defender suite deployment.

Enhanced Efficiency
Ensured real-time security monitoring (24×7) and automated response to security incidents and attacks with advanced correlation techniques; augmented efficiency by reducing mean-time to detect response, and correlation of data breach and response by leveraging SOAR-led automation.

Optimized Operation
Optimized the security operations and costs by reducing efforts on noisy false-positive alerts with the help of EUBA and contextual Threat Intelligence, and by automating repetitive manual processes with effective Playbook, Workbook design, and ITSM integration.

Ensured Security & Compliance
Assisted in meeting industry-recommended compliance standards by deploying Cloud SIEM/SOC and Microsoft Defender suite.
