It was shortly after the pandemic struck in March 2020 when Alamada-Contra Costa Transit District realized they had a problem. This is how it happened, said Tas Jalali, AC Transits head of cybersecurity, in an interview with Industry Insider California. I was hired in late 2019, early 2020 to build the cybersecurity practice. At that point, AC Transit was running a traditional security email gateway. I do not want to mention the vendor, but it was not effective; there were a lot of challenges with it.
