With every package you have the option to purchase add on services as needed:


You could get compliance assistance from a number of places.
Compliance consultancies
Will reduce some barriers to market and give you expert guidance on your regulatory pathway…
But
They’re expensive and leave you with static evidence that goes out of date when your processes evolve.
Other compliance platforms
Will simplify the work and save you time with self-serve tooling...
But
The accountability stays with you. If your evidence gets challenged, you're the one carrying the risk.
Reasons Squirrel™ is the best of both worlds:
The support of a consulting company. The efficiency of a compliance platform. Better than both.
