# Best Penetration Testing Services - Page 17

  *By [Lauren Worth](https://research.g2.com/insights/author/lauren-worth)*

   Penetration testing services providers help businesses uncover vulnerabilities within their computer systems, networks, and applications. They are managed service providers that help companies by exposing defects and known security vulnerabilities and testing the security of their communication channels and integrations. They perform this by simulating cyberattacks that target known vulnerabilities and general application components in an attempt to breach core systems, which helps detect exploitable vulnerabilities. They may also use several open-source intelligence (OSINT) tools. The service providers document these potential vulnerabilities and report them to the clients. Some service providers may also offer assistance to remediate the vulnerabilities and further perform retesting.

Businesses can deploy penetration testing software in lieu of or in addition to penetration testing services to maximize security awareness and protection.
