I think there is reason to be cautious but also reason to be realistic. There will be people interested in your formulations etc but almost certainly not as much as you think they are.
A podcast I love, called Revisionist History went into depth about a product I have no idea about because I live in the UK but it's apparently a very famous English muffin. Hilarious in itself because while muffins are a thing, they're not exactly a big deal. If I'm going to have a decent bread based food, it's going to be some proper sourdough as far as I'm concerned.
Anyway, I digress. The owners of the company prevented an employee of that organisation going to a competitor because he might take "their secret recipe".
I will cut a long story short.
Their secret recipe is a bog standard English muffin. Nothing special, nothing artisanal. In fact to try and replicate the recipe they kept having to make it worse and deliberately make it stale.
I'm sure industrial espionage is a thing but cyber security is a more important one. Someone malicious is more likely to hold your systems to ransom nowadays than steal your secret sauce. Ask M&S and COOP in the UK. When hackers got in their systems and presumably had access to every formulation specification they have, they didn't bother recreating Colin the Caterpillar cakes or Percy Pigs (if you know, you know) but they held their payment and ordering systems to ransom costing the company millions and millions of £s.
So I'd agree. Review it and make it really risk focussed.
