Cisco plans to make its third acquisition of 2023 to protect email, cloud office applications, and enterprise communications through natural language understanding through the acquisition of Armorblox.

Terms of the acquisition, which are expected to close by the end of July, weren’t disclosed, and Cisco declined to make an executive available for additional comments. IT-Harvest estimates that Armorblox is worth between $71 million and $97 million based on available funding and revenue data.


Cisco has recently purchased Valtix to enforce policies across public cloud environments and agreed in March to buy Lightspin for a reported $200 to $250 million to deliver context, prioritization, and remediation tips for cloud native resources.

Armorblox was founded in July 2017, employs 126 people, and has raised $46.5 million in four rounds of outside funding. It will join Cisco’s security business group and bring generative AI experiences to the company’s security portfolio. Valtix will also join Cisco’s security team while Lightspin will join the company’s emerging technologies and incubation business, which focuses on cloud-native and cloud security technologies.
