As of today, there’s a new company under the Alphabet banner: Google X announced a new spinoff focusing entirely on cybersecurity, dubbed Chronicle.

Billed by Google X chief Astro Teller as a “digital immune system,” Chronicle focuses on detecting threats by analyzing and storing security-related data within large enterprises. Using Google’s infrastructure, the company claims to be able to detect threats faster and at a broader scale than existing systems, which is potentially the key to stopping hacks early.

“We think we’ll be able to help organizations see their full security picture in much higher fidelity than they currently can,” founder Stephen Gillett said in a Medium post announcing the launch.

Further details on the project are still thin, but Gillett says early alpha versions of the product have already been tested at a number of Fortune 500 companies.

Chronicle will also include VirusTotal, a popular malware-reporting network that receives over 1 million submissions a day. Acquired by Google in 2012, VirusTotal’s services are expected to continue unaffected by the launch, although it will now be nested under Chronicle.
