The Breakdown of Penetration Testing

Penetration Testing, or “pentesting” for short, is a process that involves attempting to exploit vulnerabilities in your systems in order to identify potential security threats. Pentesters use a variety of methods to try and gain access to your systems, including but not limited to:

  • Scanning networks and devices for open ports and vulnerable services
  • Exploiting known vulnerabilities in applications or systems
  • Brute force attacks against user accounts

Once pentesters have gained access to your systems, they will attempt to exploit any vulnerabilities they find in order to gain control of your systems or sensitive data. This allows businesses to identify and fix these vulnerabilities before they can be exploited by actual attackers.

The Importance of Penetration Testing

So why is pentesting so important? Simply put, it’s because pentesting finds vulnerabilities that other security measures might not find, this becomes even more substantial the bigger your business is. For example, firewalls and antivirus software can only detect threats that are known at the time of installation. New exploits and attacks are discovered all the time, so relying on these measures alone is not enough to protect your business from cyber-attacks. Pentesting provides an additional layer of security by identifying these vulnerabilities before they can be exploited.

The Risks of not Performing Regular Testing

So what happens if you don’t perform regular pentesting on your business? Well, the risks are pretty significant. First of all, you’re leaving your systems open to attack by anyone who knows how to exploit the vulnerabilities that have been found. Additionally, you could be violating industry regulations or even facing legal action if your systems are compromised and sensitive data is stolen.

Finally, the most significant risk of all is the impact that a cyber-attack can have on your bottom line. A recent study by IBM found that the average cost of a data breach is now $3.8 million, and that’s just for small to medium businesses! The cost of a data breach can be much higher for larger businesses, and can include things like loss of business, damage to reputation, and fines from regulatory agencies.


In conclusion, pentesting is a vital part of any business’ cybersecurity strategy. By identifying and fixing vulnerabilities before they can be exploited, you can reduce the risk of a data breach and protect your business from financial damages. If you’re not currently performing pentesting on your systems, now is the time to start!

Penetration Testing is a set the assessment of an application infrastructure or network from an outsider's or internal perspective. So the bigger company get, the more more important it becomes as the threat landscape increases, it becomes more and more substantial as search able to give us for actors the opportunity to exploit a business. So it is imperative that you do it on every six months or yearly basis depending on the size of the company. So penetration testing allows you to gauge what your infrastructure application or network is like it can allow you to like find holes in security, plug them and ensure that your company and its on your clientele are secure. So without performing testing on a regular basis, it can leave the opportunity for vulnerabilities to grow and become more substantial and in turn can allow for actors to exploit them which could in turn, leave clientele at risk. If you leave a company at risk ruin the reputation financial assets and the actual hardware or software itself could be exploited. I hope that's been educational informing you on how penetration testing can benefit yourself and your clientele. Thank you for your time.
