Penetration Testing

Finding weak points in your system before the attackers do.

Triskele Labs’ expert-led Penetration Testing identifies your security weaknesses before real-world attackers do. 

Our Penetration Testing Services

We penetration test a wide range of systems from external networks to mobile apps and beyond. Our offensive security experts use real-world attacker tactics to simulate breaches across: 

Web Applications
Mobile Applications
Internal Networks
External Networks
Wireless Networks

Web Applications 

Whether you are engaging us to test a newly released web application, or simply wanting routine annual penetration testing as part of best practice (or as part of compliance), we offer some of the most advanced certifications for web application testing, including OSCP, OSWE, OSCE and more.

Our specialists draw on a comprehensive framework utilising, the Open Web Application Security Project (OWASP) – leveraging public, and our own Common Vulnerabilities and Exposures (CVEs) - many of which are unique findings from the sheer number of applications we’ve tested.

Critically, we are accredited by CREST International, a “best-in-class” certification - a testament to our technical competency and professionalism.

Mobile Applications

Mobile applications are inherently insecure, simply because they haven’t been around as long as other platforms such as Web Applications. Security can also be a low priority in the development process (compared with, say, usability).

With specialised mobile application security experts on our team, we test mobile apps for banking, government, retail and more, making sure their integrity cannot be compromised.

Internal Networks

It’s one thing to have a hard external shell to your network - but it’s just as important to have a bulletproof internal network.

If an attacker gets through the external network or into your internal network through social engineering, you don’t want to make it easy for them to move laterally inside your network, access your sensitive information, cause havoc, or even embed themselves quietly within your systems without your knowledge. Likewise, you don’t want attackers, should they infiltrate your company, to be able to easily escalate their permission levels and be free to roam your network.

Penetration testing of internal networks is critical for all organisations and will reveal the missing patches and other vulnerabilities before they’re found by the wrong person. We can do this remotely by sending you a device that you connect to your internal network for us - or we will come to your premises in person to test your networks onsite.

External Networks

A hard outside shell on your network is your first line of defense, and its strength can be gauged with external network penetration testing.

We’ll be armed with your organisation’s IP address range and URLs to ensure we are testing the whole external attack surface of your organisation.

During the penetration testing we will test for everything from missing patches on servers, through to known vulnerabilities in your VPN and everything in between.

Wireless Networks

Wireless networks are inherently insecure by nature as they leak outside your premises, providing the opportunity for anybody to connect to them if they are in range. Even if you have a password, or require your users to log in with their username and password, the network can still be breached.

We bring our team onto your premises to test the configuration of your wireless network and ensure the right controls are enabled. This is especially important as attackers with a long-range antenna can pick up your network from miles away.
