YOUR CHALLENGES

An evolving threat landscape demands stronger, more adaptive protection

Modern threats target identities, exploit gaps by evading siloed solutions, and overwhelm security teams with alerts. Businesses need stronger, more adaptive protection across their Microsoft environment.

Identity-driven attacks

Business email compromise (BEC) and session hijacking routinely bypass MFA, making identity a primary entry point for attackers across Microsoft ecosystems.

Evasive, human-led ransomware

Adversaries use remote encryption and hands-on-keyboard techniques designed to evade Microsoft security solutions.

Operational and licensing gaps

High alert volumes and limited in-house expertise strain security teams, and organizations face visibility and response gaps without Microsoft E5.
