CloudTech24 provide businesses in London with comprehensive penetration testing.
Our penetration methods and techniques are CREST-accredited. The procedures we follow identify and mitigate the risk of cyber threats harming your business.
We do this via ethical hacking; in other words, we simulate the act of an attacker attempting to gain access to a corporate system.
Why conduct a penetration test?
Penetration testing is useful to discover security flaws in your current IT infrastructure and applications.
Network penetration testing is designed to test the security posture of your network and how difficult it is for a malicious actor to extract sensitive data via your network infrastructure. This testing looks at the possible existence of external and/or internal threats and extent of the damage that could be caused.
Web application penetration testing simulates an attack on your web applications (such as a website or a phone app) to see whether or not unauthorised access to these systems can be gained by an external threat if they exploit vulnerabilities.
The purpose of both is to develop and provide a deep understanding of your current cyber risk. Ultimately, it is your responsibility to act on the remediation advice we provide.
CloudTech24 provide our digital assurance and London pen test services for a variety of different business reasons. The most common of these are:
- A confirmed cyber security breach
- Data protection concerns
- Investor/Client request
- Compliance or regulatory requirement
There does not necessarily need to be a compelling event, however. Frequent or annual penetration testing leads to good cyber hygiene and attack surface reduction.
