Cloud-based email management firm Mimecast faced a cyber attack which disrupted email service for its clients.
Mimecast Chief Executive Peter Bauer was quoted by Reuters as saying, "Mimecast experienced malicious traffic from multiple IP addresses, targeting its U.S. network. This resulted in service disruption for U.S. customers."
The company said the service had since returned to normal. It did not disclose further details on the attack.
In July this year, Mimecast opened Australian data centres to address email disruption and data residency issues.
The facilities help form a network of ten data centres globally, serving the email security and data needs of more than 13,000 customers and several employees.
Mimecast’s cloud-based security, archiving and continuity services protect email, and provide email risk management in a single subscription service.
For customers that have migrated to cloud services such as Microsoft Office 365, Mimecast mitigates single vendor exposure with expanded security coverage and enhanced archiving.
