    How Blumira Detects M365 Common Attacks

    See how Blumira stops these common attacks before they begin.

    • User & Access Security

      Monitor Microsoft 365 Login Activity

      Attackers may attempt to take over legitimate user accounts in your Microsoft 365 environment to gain initial access or move around laterally. Blumira detects:

      • Whenever multi-factor authentication (MFA) is disabled for an Azure Active Directory (AD) user

      • Anomalous access attempts or the creation or deletion of an application password

      • Any time a user clicks on a malicious URL or is restricted from sending an email

      • Any impossible travel activity, indicating unauthorized access

      • Multiple failed user logon attempts

    • Detect Privilege Escalation

      Detect Privilege Escalation

      Easily detect when Microsoft Exchange administrator privileges are elevated, which could indicate an attacker is attempting to gain additional permissions within your environment. Blumira identifies and sends you playbooks to respond to:

      • Privilege escalation

      • Creation of forwarding and redirect rules

      • Suspicious inbox rule creation

      Attackers may use inbox rules to remove or delete emails in order to lengthen the amount of time before a compromise is detected.

    • Stop Data Exfiltration

      Stop Data Exfiltration

      Secure your data by detecting signs that an attacker or malicious insider is stealing your organization’s information. Blumira identifies:

      • When files are shared with personal email addresses

      • Mass file downloads

      • Whenever an email send limit is exceeded. This will protect against spam campaigns

    • Track Ransomware Activity

      Malware & Ransomware Indicators

      By detecting indicators of malware and ransomware early, Blumira helps your organization act quickly to minimize impact. Get alerted to:

      • High rate of file uploads or deletion activity that could indicate an adverse encryption process

      • Malware campaigns detected in SharePoint and OneDrive

      • Malware campaigns detected after mailbox delivery

      • Failed zero-hour auto purge when Microsoft’s email protection features are disabled

    • Identify Unusual Microsoft 365 Activity

      Identify Unusual Microsoft 365 Activity

      Blumira tracks anomalous activity in your environment:

      • Any activity from anonymous or suspicious IP addresses

      • Activity from infrequent countries or terminated users

      • Unusual external file behavior

      • Increases in phishing emails or ISPs (internet service providers) for an OAuth application

      • Suspicious email sending patterns

    • Reports & Summary Dashboard

    Helping IT Teams Protect Their Microsoft Environment

    Hear what our customers are saying.

    I researched a number of SIEM providers online and found most were way out-of-the-ballpark expensive, required a lot of infrastructure and didn’t provide a great return on our investment.

    Fritz Ludemann
    Information Systems Administrator The City of Crescent City

    Blumira added a new detection for malicious PowerShell activity. It flagged some activity in our environment. Blumira’s SecOps team immediately jumped on, saw that the scripts were legitimate activity coming from the Microsoft System Center monitoring agents, notified us that the alert was a false positive and that they had updated the detection rules for us.

    For a certain size of customer with no staff or only one security staff member, Blumira is an absolute godsend.
