Cisco completes acquisition of Duo Security


Cisco has announced that it has now completed the acquisition of Duo Security, bringing Duo’s unified access security and multi-factor authentication via the cloud to its product portfolio.

Cisco announced its intent to acquire Duo Security, a privately-held security company from Michigan, back in August, and today, Cisco was quite keen to announce the completion of this $2.35 billion heavy acquisition.

Meant to prevent cybersecurity breaches, Duo’s solution both verifies the identity of users as well as the health of their devices before allowing them access to applications. The solution will be integrated with Cisco network, device and cloud security platforms, and bring zero trust authentication and access, bringing a new level of security.

Cisco was keen to note that Duo’s technology will be a key in helping to accelerate Cisco’s intent-based networking strategy by extending intent-based networking to multicloud environments, simplifying policy for cloud security, and expanding endpoint visibility coverage.

Duo’s CEO and co-founder, Dug Song, and its team will be integrated into Cisco’s Networking and Security business led by EVP and GM David Goeckeler.

In a dedicated blog post regarding the acquisition, Cisco’s David Goeckeler noted that with “Duo’s cloud-delivered technology, it is easy to establish per-user and per-application policies to restrict remote user access, so employees access only what they need to do their job. In doing so, customers have even greater threat protection by being able to prevent lateral movement.”

It will be interesting to see what future security advancements will Cisco introduce based on Duo’s technology.
