Cyber security has become essential for every organisation. With cyber-attacks and data breaches on the rise, businesses must proactively identify vulnerabilities before criminals exploit them. One of the most effective defences is penetration testing - a controlled process that uncovers weaknesses and strengthens your overall security posture.
If you’re searching for trusted penetration testing companies in the UK, understanding what to look for - and why Wavenet stands out - can help you make the right choice for your organisation.
What is penetration testing?
Also known as ethical hacking, penetration testing simulates cyber-attacks on your systems, networks, or applications. The goal is to find and fix vulnerabilities before attackers can exploit them.
This pro-active approach helps you:
-
Identify system and application weaknesses.
-
Prevent costly data breaches.
-
Maintain compliance with cyber security regulations.
-
Build customer confidence through demonstrable protection.
Types of penetration testing
Different testing types target various layers of your digital infrastructure:
-
Network penetration testing: reviews your firewalls, routers, and connected devices for exploitable vulnerabilities.
-
Web application testing: finds flaws like SQL injection or cross-site scripting (XSS) that could compromise your website.
-
Mobile application testing: identifies weaknesses in mobile apps and APIs.
-
Social engineering: evaluates employee awareness through phishing or impersonation simulations.
-
Physical security testing: tests access control and on-site security defences.
