Penetration Testing FAQ

Do you need penetration testing?

arrow_drop_down

Businesses cannot fully estimate the strength of their security posture unless it is tested. Here is where penetration testing comes into play. It helps businesses understand if their security policies are effective by identifying and mitigating vulnerabilities that can be exploited by attackers.

Penetration testing is deemed a requirement by regulators in some industries, while an optional yet essential security practice in others. However, it is recommended to conduct penetration testing periodically to constantly upgrade your defense against evolving threats.

How often should you get penetration testing?

arrow_drop_down

Penetration testing is seen as a periodic security practice, to help identify and mitigate vulnerabilities that have been unidentified, ignored, or unmanaged. It is the best way to check the resilience of your internal and external systems, networks, and applications.

It is recommended to conduct penetration testing once annually, or more often in case of a high-risk industry. Penetration testing can also be done when organizations are adding new features, upgrading systems, or testing a new system in terms of handling sensitive information.

What is the difference between penetration testing and vulnerability assessment?

arrow_drop_down

Penetration testing confirms whether vulnerabilities can actually be exploited and maps out potential compromise paths. Vulnerability assessments, on the other hand, focus on identifying and cataloging weaknesses and misconfigurations across your environment.

Should you choose internal penetration testing services or external penetration testing services?

arrow_drop_down

Both are essential components for complete security testing. External penetration testing assesses the external facing assets (internet-connected devices, employee accounts, etc), and internal penetration testing helps analyze how far an attacker can laterally move through a network after exploiting a weakness that leads to a breach.

A complete security testing program will include both internal and external penetration testing, as well as another social engineering testing which involves identifying shortcomings in existing security solutions, assessing the possibility of attackers using social vectors, and ascertaining to what extent the organization’s employees are aware of information security issues.
