Mimecast has closed on a deal to acquire the digital threat protection firm Segasec.

While the merger’s financial details were not revealed, a Mimecast spokesperson told SC Media that the deal was closed on January 3 and that all Segasec personnel will be integrated into Mimecast.

Mimecast executives said the addition of Segasec technology will help its customers protect against attacks taking place outside the perimeter in the larger cybersphere by providing a comprehensive approach to digital risk protection.

“Segasec will allow our customers to take a proactive approach to identifying — and even potentially preventing — attacks that imitate their brands using domains they don’t own, while also offering the visibility required to understand how their brands are being misused for malicious intent,” said Peter Bauer, Mimecast’s CEO. Bauer also noted that the Segasec deal ties in with the company’s  recent acquisition of DMARC Analyzer
