Office 365 Security Monitoring

24 X 7 Office 365 Security Monitoring – All Activity in your Office 365 environment

Our Office 365 security monitoring solution protects against suspicious account login attempts from outside the office, data exfiltration from SharePoint or phishing emails that arrive in your employee’s email.

More and more companies are switching to cloud productivity solutions like Microsoft 365 due to the many benefits it can provide. Unfortunately, with all the benefits Microsoft 365 has, there are also disadvantages, especially in terms of security.

The DNA IT Office 365 security monitoring service overcomes these problems by combining artificial intelligence (AI) and machine learning (ML) along with our fully staffed security operations centre (SOC) team, who are correlating user behavior to identify abnormal behavior. This is the kind of information that truly identifies attackers are inside an organization.

When a cloud account is breached, anti-virus solutions or internal solutions like firewalls won’t be triggered. The DNA SOC team will spot the attacker as they navigate their way across the network. An unusual login location or lateral movement across the network to find and exfiltrate files is what stands out.
