Penetration Testing , also known as ” Pen Testing “ or “Ethical Hacking” is the practice of testing assurance in the security of an IT system by identifying the weaknesses in the system that an attacker could exploit. The goal of pentesting is to minimise the number of retroactive upgrades and maximise organisation’s security to build a trust-worthy brand.
Penetration testing is typically performed using manual or automated technologies , or sometimes testers may use a combination of both. Automated tools have the advantage of thoroughness and consistency. These tests are repeatable , so they can measure progress or compare different installations. The manual approach lets testers use their intuition.
Choose your Penetration Testing Provider Wisely
Looking for the best Pen Testing Company but haven’t found one? Here’s everything you need to know before you face a cyber attack :
To find the best Penetration Testing Company , the two most common reasons your organisation may need to consider are :-
Compliance with various data security requirements like PCI DSS or ISO 27001 compliance scans , and ; Getting a Comprehensive Understanding of the Cyber Security Risks that your organisation is facing.
Penetration Testing is important to determine whether your system is secured from outside intrusion. You can lose your money if the PenTest goes incorrect. While hiring a security company , one must look for the quality of the service they are providing and their reputation they have in the market.
Crucial Areas that should be receiving a Pen Test
- External Network Penetration Testing
- Internal Network Penetration Testing
- Web Application Penetration Testing
- Mobile Application Penetration Testing
- Physical Penetration Testing
- Wireless Penetration Testing
- Social Engineering Penetration Testing
- Cloud Penetration Testing
