Intruder was founded in 2015 to help solve the information overload crisis in vulnerability management. Having worked both as an ethical hacker for tier one companies, and for blue teams defending critical national infrastructure, Founder Chris Wallis noticed that while vulnerability management tools were great at finding issues, they were less useful when it came to prioritizing them, tracking them, and timely alerting when problems arose. Quite simply - the most important issues were often getting lost in the noise. Intruder's mission from day one has been to help divide the needles from the haystack, focusing on what matters, while ignoring the rest. Effective cyber security is about getting the basics right. Intruder helps you do that, saving time on the easy stuff, so you can focus on the rest. Since its inception in 2015, Intruder has been awarded multiple accolades, was selected for GCHQ's Cyber Accelerator, and was included on Deloitte's Tech Fast 50 2023 list as the fastest-growing cybersecurity company in the UK.

Cyber Security is important because it helps to protect sensitive information and prevent disruptions to business operations. It is particularly important in today's digital age, as more and more devices, systems, and networks are connected to the internet, increasing the potential for cyber-attacks. Cybersecurity measures are used to protect against a variety of threats, including viruses, malware, phishing attacks, unsecured networks, and weak passwords. With Cyber Crime rising at a devastating rate, Cyber Security has become a compulsory component of every business. Companies must now be more vigilant and take a more proactive approach to protect their business and their clients. At The Cybercell we commit to protecting devices, networks, and systems from digital attacks, theft, and damage. Our process involves implementing technologies, processes, and controls to secure networks, devices, and data from unauthorised access or attacks.

Frequently asked questions

Updated 23 October 2026

What is Enterprise League?

Enterprise League is a free business directory that helps buyers find the right company by sector and country. Every company has a profile showing what it does, what it offers and how to get in touch.

Is it free to list my company?

Yes, and it stays free: no card, no paid tier. Your profile appears in search results and category pages, can show up to 20 products and services, and lets buyers message you or ask for a quote.

How does verification work, and what does it cost?

Verifying your company is free. Confirm a code we email to an address at your company’s website, or send a company registration document for our team to check, and the verified badge appears on your profile. To show the badge in the directory and search results as well, take out a subscription: the first 14 days are free, and the price is on our pricing page.

Where does the company information come from?

Most profiles are built from public sources, such as official company registers. Claim your company’s profile to correct its details and add your own.

How do I claim or correct my company’s profile?

Open your company’s profile and choose Claim Profile. If you use an email address at your company’s website, a 6-digit code makes the profile yours at once; otherwise our team reviews your request, usually within a few days. Spotted a mistake on a company that isn’t yours? Tell us through our contact page.
