Penetration Tests Can Help Spot Vulnerabilities 

To get companies into the mindset of defending against hackers, Kon strongly recommends penetration testing.

Most large companies already conduct periodic penetration testing themselves or hire an outside company for that purpose, Kon said. Higher-level, higher-exposure companies will often conduct penetration testing on their systems as well, he said.

A basic penetration test will cost a couple thousand dollars, Kon said, while a more complex test will likely run six figures.
