I am trying to pull security events for the past 6 months for a customer. I am using GET /networks/{networkId}/securityEvents and am specifying the timespan to be 183*86400 seconds. The documentation says that the default timespan is 31 days and you can go back as far as 365 days.
However, I am only getting data as far back as 2/5/20. If I remove the timespan parameter, I get the same time period. Has anyone tried to get data more than about a month old for security events? Based on my data today, it looks like the maximum you can get is about 35 days.
