________% of F5 products are sent through thorough software testing before being sold to customers.

F5 Networks maintains a comprehensive quality assurance policy in which every single product - representing 100% of its portfolio - must pass thorough software testing before customer delivery. This complete coverage is integral to F5's focus on reliability and security in application delivery networking. No product is exempted from the testing pipeline prior to release.

50% is incorrect because F5's quality assurance program is not a partial initiative - it applies to the entire product line, not half of it.

60% is incorrect because F5 does not have a policy that allows any portion of its products to bypass pre-release software testing.

80% is incorrect because F5's stated testing policy covers all products with no exceptions before they are sold to customers.
