Cloud email security and brand protection startup Redsift Ltd. revealed today that it has acquired attack surface management company Hardenize Ltd. for an undisclosed price.

Founded in 2016, Hardenize offers a platform for automated discovery and monitoring of an entire network perimeter. The company’s continuous monitoring and discovery services monitor infrastructure and certificates to prevent breakage and protect enterprises.

Hardenize’s internet asset inventory and monitoring combines automated discovery with continuous network and security configuration monitoring to find properties to start monitoring them immediately. The company argues that no one wants to spend their time populating a database and hence, the platform draws from multiple sources of information to maintain a search engine that can help identify sites.

The platform supports cloud integrations, enabling users to connect their Hardenize account to Amazon Web Services Inc., Google LLC Cloud, Microsoft Corp. Azure and other cloud accounts. Notable Hardenize customers include Rakuten Group Inc., Opera Ltd., Digicert Inc., DebtBook, Merced Capital LP and DENIC eG.

For Red Sift, the acquisition is described as a strategic move to enable the company to enrich, extend and improve its existing security solutions to protect customers’ internet assets and infrastructure. Hardenize’s ASM capabilities will give the Red Sift platform a comprehensive view of an organization’s digital footprint, allowing customers to better understand and protect their entire critical attack surface area in the face of an ever-evolving threat environment.

Hardenize’s discovery capabilities will “act as a magnifying glass” into customers’ infrastructure, continuously identifying new and often unknown vulnerable assets across the attack surface. By enriching Red Sift’s discovery phase, customers can uncover threats beyond email security, discover lookalike domain abuse and spot vulnerabilities across their network perimeter.

“This move gives us the purview to do more for cybersecurity than we ever have before, elevating the breed of solution available to enterprise businesses for full attack surface management and resilience,” Rahul Powar, chief executive officer of Red Sift, said in a statement. “By acquiring Hardenize… we extend our leading security products beyond protecting email, enabling enterprise customers to see their full attack surface, solve the issues at hand, and secure their valuable assets in an ever-evolving threat continuum.”

It’s unknown whether Hardenize raised any venture capital coming into its acquisition. Red Sift was last in the news in February when it raised $54 million in new funding to accelerate its global expansion and double down on its platform innovation. Red Sift investors include Sands Capital, MMC Ventures, Highland Europe, Hambro Perks, White Star Capital and In-Q-Tel.
