The realm of cyber security is vast. As the world becomes more interconnected, the threats to data security multiply. Each new connection is a potential gateway to malicious intruders. Depending on the profile and needs of your business, you may need specialist protection alongside a well-rounded cyber security company like Prosyn. According to the well regarded Cybersecurity 500 list, London is the 7th biggest city in the world for cyber security ventures.
