Before
You collect Social Security numbers, bank details, and signed leases. If any of it leaks, you are the one explaining it to your tenants, and possibly to a lawyer.
After
Applicant SSNs and tax IDs are encrypted with AES-256, the same encryption standard the U.S. government approves for classified information. Only the last four digits ever appear on screen. Your database is encrypted at rest and every connection is encrypted in transit.
