Evaluate email  attachments sent before they reach your inbox.


Topsec Attachment Sandboxing allows clients to better evaluate dubious attachments.

Email attachments are a major source hackers use to get access to your computer. To avoid such harmful email attachments, attachment sandboxing is a popular solution. It takes out the attachment from the email and safely checks for malicious or suspicious files inside these attachments.

Attachment sandboxing is a cloud-based service that reduces the risk of malicious attachments slipping past email security measures. It analyses each individual email message that has an attachment by extracting the file from the message and placing it in a secure environment “sandbox”. The attachment is opened and monitored for any suspicious attempts to download harmful components.

Secure your system from malware and other advanced attacks with Topsec’s Attachment Sandboxing feature.
