Cyber Security

Cyber security seems to be in the headlines so much more these days, from organised hacking groups to destructive and costly ransomware, state-sponsored attacks and lone cybercriminals we have seen it all.

Penetration testing is a modern-day necessity, and this is where someone friendly like us probes your company's entire I.T systems landscape to expose weaknesses, so you can plug any gaps before any outside threats maliciously target them, think of it as paying an "ethical" hacker to break into your systems so you can learn how they got inside.

Unlike most penetration testing firms, Zero42 specialises in helping small to medium-sized businesses uncover what threatens them the most and the steps required to protect themselves, with a host of services that even the non-I.T savvy will understand.

A typical mission

No two penetration test missions are the same, there are far too many variables but here are the steps each engagement will follow to give you some kind of idea of the work involved.

  • 01. Agreement & Scope

    Both sides agree on the scope of engagement and what is on and off-limits within our mission, after all, you may have some stuff you wish to hide.

  • 02. Planning & Reconnaissance

    Planning always takes time, we work hard to gather as much information about our target as possible and that means watching how your business interacts digitally as well as the people around you.

  • 03. Scanning Vulerabilities

    During this phase of the attack, we interact with our chosen targets and send probes deep into your digital infrastructure, we look for weaknesses in open ports and systems with social engineering and manipulation just like a rogue attacker would.

  • 04. Gaining Access

    Once the vulnerabilities have been identified we then carefully check each one in turn for access and to see which are exploitable and which provide us with the best leverage into the very heart of your infrastructure.

  • 05. Maintaining Access

    Now that we are inside your networks, we like to make sure that we can maintain access and move around without setting off any alarms or raising suspicion and that means replicating our methods of entry or creating our very own hidden entry points.

  • 06. Exploitation

    This is the phase where actual damage could be done, a real cyber attacker would try to get hold of data, compromise your systems and launch malicious code. Our experts will not however cause mayhem or do damage but prefer instead to leave behind little gifts for you to collect or pick up any flags you may have left for us.

  • 07.Evidence Gathering

    Now we have compromised most if not all of your systems, we put together evidence of our exploits in a digital scrapbook which you get to keep. This book will provide you and your team with insight into the methods used, and the information gathered.

  • 08. Final Reporting

    The final part of the penetration test is the generation of a comprehensive report detailing each of our exploits and providing you with best practices of how to prevent further attacks.

    We could always go further [additional fees apply] and actually implement any changes for you, or maybe run one of our fun security seminars to help educate your staff on how to best protect the business and themselves.

Penetration testing packages

We have three main packages, these fit the majority of end-user scenarios but we will also custom design something different for you if you prefer.

Network Security is the process of taking physical hardware and software preventative measures to protect the underlying network infrastructure from unauthorised access, misuse, modification, destruction, or disclosure.

Mitigating risk and prevention rather than cure is key to creating a secure platform for computers, users and programs to perform their individual functions. In today's business climate, network security must be top of the list of requirements for any I.T manager or online business.

The size of an organisation is usually pretty irrelevant to most computer hackers. However, the kudos of taking on the very biggest corporations is the driving factor behind any network attack for some. Most "unethical" attacks are carried out by individuals motivated by financial or commercial gain. While there are many things an organisation can do to reduce the risk of attack, there is no such thing as being totally un-hackable forewarned is forearmed.

We have over 35 years of experience in network design and systems security and have worked with some of the U.K.'s most prominent government agencies and blue-chip organisations. Our system security & evaluation skills are the same as those employed in signals intelligence and defence intelligence here in the U.K.


A white hat hacker is a computer security specialist who breaks into protected systems and networks to test and assess their security. White hat hackers use their skills to improve security by exposing vulnerabilities before malicious hackers (known as black hat hackers) can detect and exploit them.

The term "white hat" refers to an ethical computer hacker or a computer security expert who specialises in computer & network penetration testing to ensure the security of an organisation's information systems and network. Ethical hacking is a term first coined by IBM to imply a broader category than just penetration testing. Contrasted with the black hat, a malicious hacker, the name comes from Western films, where heroic and unfriendly cowboys would traditionally wear a white or black cowboy hat.


  • We offer a wide range of "pen test" services tailored to each individual client's needs and system-specific requirements. We thoroughly document the entire testing process and demonstrate system vulnerabilities by adding pre-agreed code to weak points in your corporate network.
  • The methods employed by our security specialists will be varied and designed to replicate "real world" attacks, whether by curious individuals or talented hacking teams and government agencies.


  • Aside from the regular penetration testing service, we also conduct a more aggressive approach to breaking into your corporate network. This may involve social engineering tasks such as employee exploitation or so-called "honey pots" designed to catch the more sophisticated network users.
  • Due to differing legislation worldwide, we only offer this service to U.K. based businesses, and only then upon the sanction of the board of directors. We do not provide this service to individual clients or those involved in political activities.


  • We recognise that not every business has the ability to recruit their own in house security specialist nor has the capacity to do so. With this in mind, we offer a one-to-one consultancy service, where we take that employee's place and can offer practical real-time advice to management or those tasked with providing your I.T services.
  • We regularly attend development meetings on behalf of clients and liaise with equipment and software suppliers should this be necessary or beneficial. Our consultancy service also extends to cover all aspects of forensic auditing and data reclamation.

We asked Michael to sort out our telecoms and data at Pinewood Studios; we received such excellent service from his technicians that they now look after all of our UK sites. Very knowledgeable and highly recommended.
