Is there genuinely free payroll fraud detection software?

Free tiers, yes; free platforms, mostly no. The standout exception is Sublime, which gives you BEC and payroll-diversion protection free for your first 100 mailboxes. Beyond that, Homebase's free tier covers single-location time-clock basics, Persona's startup program includes 500 verifications a month, and whatever payroll system you already pay for probably includes controls you haven't turned on. Heavy-duty anomaly analytics is where free really ends — that software is expensive to build and priced accordingly.

What's the best defense at exactly zero budget?

Process, not software: the owner reviews every payroll register before it releases, banking changes get callback-verified at a known number, and the payroll bank statement gets read monthly by someone who doesn't run payroll. That combination beats most paid tools on prevented-loss-per-dollar — the paid tools earn their keep when headcount makes eyeballing impossible.

Are there payroll fraud detection tools that are actually free, not just cheap?

Sublime (BEC/diversion, free to 100 mailboxes) and Jibble (facial-recognition time clock, free for unlimited users) are the two genuinely free-forever tools on this list, not trials with a countdown. Everything else here is a free tier attached to a paid product you'd likely run anyway.
