Headcount: 65 (+225%)
Specialism: Cybersecurity
HQ: Leeds
Having ranked 16th in last year’s Fast-Growth 50, this Leeds-based cyber specialist hops four places in the pecking order on the back of continued organic headcount expansion.
Annual accounts for its fiscal 2020 to 2024 show average monthly headcount hiking from 20 to 65 – a tally it told us has risen to 95 as of March 2025.
Founded in 2016, the privately held company counts Check Point, Google Cloud, CrowdStrike, Pentera, Egress, LogRhythm, KnowBe4, Qualys, Keeper and Island as its ten go-to vendors.
Q&A with SEP2 CEO Paul Starr

You’re one of the UK’s fastest growing IT solutions providers by headcount. What would you attribute that to?
For nine years, we’ve stayed true to our values by focusing on our people and partners, and providing the best training, development, and succession planning. Our unwavering commitment to delivering exceptional service and value to our customers has brought us the success we enjoy today, both in the UK and globally.
What’s your biggest growth bet for 2025?
Our Wingman MDR service has seen tremendous growth over the last couple of years, and we don’t see any reason for that to slow down. We have spent the last couple of months really defining our Go-to-Market strategy around our seven core Wingman services. These are what we do best, and while there are plans for us to add to these, I feel that SEP2 has a great opportunity to take these services to our partner community within the channel.
What’s been your biggest tech let down of the last 12 months?
This is a thought-provoking question for me, as AI has the potential to transform our work processes. However, my disappointment concerns the extensive use of AI terminology by various vendors, especially when you dig deeper, and they are in fact talking about automation. This really pains me as Automation is not AI!
The primary issue seems to be the frequent overuse of the term and jumping on the marketing bandwagon. While I do agree that AI will revolutionise our world and work methods, it appears to me that the cyber security industry is overstating its application and begun promoting it as a human replacement.
Name one thing your company has planned for the next 12 months
We’re holding our second SEP2 Cyber Summit on 15 May in London. After an incredibly successful inaugural event in 2024, this year’s Cyber Summit has already seen record registration figures, while our brilliant vendor partners are all keen to be present. Our hope is for SEP2 Cyber Summit to become a must-attend event in the industry, and 2025 looks set to make that a reality.
