Samurai XDR will monitor all activity in your Microsoft 365 account and alert you to suspicious activity and threats.

As more and more applications and data move into the Microsoft 365 cloud, threat actors can attempt to breach companies without getting anywhere near the company assets or network.


Top issues with Microsoft 365 cloud environments


Misconfiguration is a huge issue when it comes to cloud assets - the latest leak of Microsoft company data through a misconfigured storage account illustrates this very well.

Samurai XDR can alert you when there is unusual access to your environment.

Email Attacks

With email in cloud platforms like Exchange Online and messaging in applications like Teams and Slack, data can be accessed without any interaction with physical assets.

Samurai XDR will detect activity by known threat actors and alert you immediately.

Living Off the Land Attacks

Stealthy Microsoft 365 attackers use “Living Off the Land” techniques. They use legitimate components of M365 like Power Automate and can often escape detection because they don’t introduce malware into your environment.

Using its Threat Intelligence and Advanced Analytics Samurai XDR is able to detect malicious activity which might otherwise go undetected.

Alert Fatigue

Platforms like M365 generate lots of security alerts. Resource-constrained IT teams need tools which cut out the noise and help them zero in on the real threats.

Using advanced analytics and techniques like Boost Scoring Samurai XDR filters out the noise and alters you to the threats that matter.

When it comes to identifying if an attack was as a result of a sequence of events or alerts (or a one-off), that's when you can use tools to search through a centralized data lake and hunt for other potential signs of a threat.

Identity Breaches

Even small organizations are moving their identity management into the cloud through products like Microsoft’s Entra Id (Azure AD) or using other providers such as Google or Okta. Breaches of user identities thus represent a much greater risk - unless you are monitoring the telemetry that your identity provider can offer you, you risk being completely oblivious of identity breaches.

Samurai combines visibility of your M365 account and your identity management solution to see and monitor all access to detect breaches.

False Sense of Security

M365 built-in security is not enough. You need to focus your attention on all of your assets and their security. This includes endpoints (laptops and desktops), firewalls, VPNs, and identity providers. Threat actors may target you over multiple of these, and you need a single view of security in your IT environment.

Samurai XDR correlates security alerts from all of your IT assets, including M365, firewalls, network and endpoints, providing you with a single point to manage enterprise security.
