We are a collection of IT experts based around the world, with a curious passion for computer security and the praying mantis. Our team is made up of freelance pentesters, security experts, network engineers, cryptographers, ethical hackers and bug hunters, with a common goal towards a safer internet.
Sitnam Tech was founded in 2019 when a Network Engineer (Matthew O'Donnell), Cryptographer (Jason Aardman), and Security Analyst (Joe Downie) got together and decided to launch a security company with the goal of bringing more security awareness to users of the internet.
We are security consultants with a heavy focus on mimicking an attack from a source that appears safe, just as the devil's flower mantis does - the purpose being to ensure that you are secure from the inside out. Get in touch with our team below.
