Why do you need us?

In order to prevent real life cyber attacks on your business ad-hoc solution must take place.

As in any business, the basic products of cyber security are generic, automated software programs that protect your systems from generic automated attacks. While this is a crucial defense it does not protect your business from unique and targeted threats.

These problems are a normal byproduct of a business’s growth life cycle and the best solution to solve these security breaches are had-hoc manual testing.
