Microsoft 365 Advanced Security Monitoring
Providing a centrally monitored security service dedicated to the security of your 365 tenant

Microsoft 365 Advanced Security Monitoring

Office/Microsoft 365 is one of the most attacked platforms in the world because of its massive popularity. Unfortunately, many people assume that their tenant is secure by default, right up until they are compromised.

J2 Software’s advanced security monitoring service provides a centrally monitored security service dedicated to the security of your 365 tenant.

There has been a significant increase in Microsoft 365 Business Email Compromise (BEC) in recent months. During the last year there were reports that the average number of BEC attacks rose by 15% per week. This attack method leads to change of bank details fraud, credential theft and payment fraud. Financially focused attacks increased by 155%, making it the most pervasive type of BEC tactic.

Your 365 tenant also exposes a successful attacker to various parts of the extended infrastructure, even more than usual due to the growing numbers of services being moved to the cloud.

The monthly J2 Software Advanced 365 Monitoring Service goes beyond the standard service and works to identify problems as they begin, not when you are front page news.

The service monitors activity in your 365 tenant to identify dangerous and malicious activity in order to respond to any attacks.

Monitoring Office 365 logs offers a variety of benefits for organisations by helping improve security maturity, provides enhanced detection capabilities and can aid compliance to policies and legislation.

By monitoring and analysing Office 365 security logs in a structured way, your organisation can achieve greater security maturity and fulfil certain important critical security controls, such as:

  • Controlled Use of Administrative Privileges
  • Maintenance, Monitoring and Analysis of Audit Logs
  • Data Protection

This is a monthly service that provides immediate alerts on the key attack points. Providing increased visibility and the capability to respond. This includes, but is not limited to, the key methods of attack:
