Compromised account detection

Email is one of the biggest threat vectors for companies of all sizes. Access to user email accounts often grants access to a wide range of other company services and gives attackers an opportunity to steal company and customer data. A breached account is an easy way for the attacker to get into an organization. The attacks done using a breached account, such as phishing campaigns or impersonation, are hard to detect because they use a legitimate company user account. The Compromised account detection feature detects compromised accounts as soon as information about the breach is available. It informs users and administrators to take action to remediate the accounts by changing the password or by taking other security measures, such as turning on the multi-factor authentication to avoid further exploitation of the breached data.

Inbox rule scanning

Inbox rules in Outlook work as a trigger to perform specific actions on incoming emails automatically. After gaining access to a mailbox, an attacker creates inbox rules to carry out different types of attacks, such as auto-forwarding and auto-deleting of emails. The scanning feature analyzes all the inbox rules in a mailbox. This analysis helps to detect any suspicious rules that may indicate a compromise of the account. It also notifies the owner of the mailbox and the administrators to take action.

File protection

F-Secure Elements for Microsoft 365 scans for harmful contents in file attachments found in Exchange items to protect against viruses, trojans, ransomware, and other advanced malware. It offers far superior protection compared to traditional technologies by leveraging real-time threat intelligence gathered from tens of millions of security clients, providing faster and better protection against new and emerging threats.

URL protection

URL protection is a key security function that proactively prevents Microsoft Office 365 users from accessing malicious or unwanted content through web links added to Exchange items such as emails, calendar appointments, tasks, contacts, and sticky notes. This makes it a particularly effective security service, as early intervention greatly reduces overall exposure to malicious content, and thus to attacks. For example, it prevents users from being tricked into accessing seemingly legitimate phishing sites and other malicious sites.

Multilayered security

F-Secure Elements for Microsoft 365 leverages F-Secure Security Cloud, which combines award-winning, multi-engine antivirus scanning, machine-learning-based heuristic analysis, and threat intelligence databases updated in real time. F-Secure Security Cloud instantly finds emerging and unseen malware variants as well as detecting a broader range of malicious features, behavior patterns, and trends.

Advanced threat detection

Advanced threat detection runs suspicious files in an isolated virtual environment (known as a sandbox) that mimics a normal computer. As the file is detonated – that is, allowed to run in the sandbox – the process examines its behavior for any harmful actions. It then returns a verdict on whether the file is clean or harmful. Clean files are allowed to run normally, while harmful files are blocked.

Advanced analytics

Advanced security analytics give full visibility into the analyzed content and ensure fast and efficient response capabilities.

Worry-free administration

Product administrators can configure settings, alerts, user notifications, and actions in accordance with their company’s security policies. The F-Secure Elements for Microsoft 365 portal allows you to manage security and quarantined items for multiple Microsoft Office 365 tenants. F-Secure partners can administer the solution for multiple end customers.

Seamless integration

F-Secure Elements for Microsoft 365 supports cloud-to-cloud integration without any need for installing additional software or making changes to servers or clients. The protection is totally platform-agnostic and capable of detecting threats regardless of which device or application is used by the end user.

Quarantine management

Microsoft Office 365 user mailbox items such as emails, calendar appointments, notes, contacts, and groups that contain harmful files or URLs can be quarantined immediately and later reviewed and restored using quarantine management.


F-Secure Elements for Microsoft 365 allows you to create automatic scheduled reports to provide a holistic overview of the secured environment that can be shared to show the value provided by the solution over a certain period of time.
