HARMAN uses Darktrace / NETWORK and Darktrace / EMAIL to detect and respond to threats across its network and email, replacing manual threat detection. Autonomous response handles most threats and alerts security analysts only to critical ones.

Summary written by usedby from the source page, in English. The figures are those of Darktrace and HARMAN International, not ours.

> HARMAN has reduced their mean time to contain (MTTC) a potential threat by 80%, reducing their previous average of 30 minutes to less to than five minutes.

- **~77.2%**: “Using Darktrace, we are blocking ~77.2% of all email flowing within the organization – both malicious and other categories of email we have chosen to classify as spam.”
- **15-20**: “Today, Blanchet says they only receive 15-20 of those alerts each day, and Darktrace / NETWORK provides their analysts with critical and actionable insights into those potential threats so they can investigate and respond faster.”
- **40 million**: “HARMAN averages 40 million emails each month.”

> Using Darktrace, we are blocking ~77.2% of all email flowing within the organization – both malicious and other categories of email we have chosen to classify as spam. That means only 23% of all email is getting through and we know they are legitimate emails. That is quite impressive.
