Threatscape is a leading pure-play cyber security specialist with an established presence in the UK and Ireland providing services and solutions trusted to protect the business-critical global IT assets of enterprise, public sector and upper mid-market clients. The business was founded in 2010 by Dermot Williams, Alan Roche, Colin Reid, Eddie Lyons, and Wendy Williams who collectively bring over 100 years of cyber security expertise and are continuing with the business during the next phase of growth.
Threatscape has deeply embedded CISO-level relationships with clients and acts as an extension of their security team supported by accredited partnerships with leading cyber security vendors including Microsoft, Palo Alto Networks, Symantec and Abnormal Security, and global MSSP SecurityHQ.
Threatscape delivers compelling security outcomes and ROI for clients via its highly skilled and experienced team including a dedicated Microsoft Security Practice ranked #1 in the UK & Ireland, and #3 globally, for the number of its senior consultants who have been awarded the coveted Security MVP status by Microsoft.
The cyber security market is experiencing significant growth supported by strong structural tailwinds and remains highly fragmented. Horizon Capital will invest in the business to support CEO Dermot Williams and the team as they execute an ambitious plan that combines continued organic growth and investment in its IP with a number of complementary acquisitions.
“I couldn’t be more proud of what our team has accomplished, or grateful to our clients for their trust, and our partners for their support.”
Dermot Williams, CEO Threatscape
Dermot Williams, CEO of Threatscape, commented: “Since founding Threatscape, we have built an outstanding company that truly becomes a trusted advisor to clients to address the ever-growing volume and sophistication of cyber security threats. We believe Threatscape can be further enhanced through a partnership with Horizon who are a natural choice given their substantial experience in technology services and we are extremely excited to embark on this journey together.”
Luke Kingston, Managing Partner at Horizon Capital, added: “Having closely followed the cyber security sector for several years, we are delighted to be backing Threatscape having identified it as an outstanding business with huge potential for growth. We are excited by the prospect of working closely with Dermot and his exceptional team and by the future prospects from this partnership.”
Dermot Williams further commented: “I couldn’t be more proud of what our team has accomplished, or grateful to our clients for their trust, and our partners for their support. Threatscape has achieved some incredible milestones including winning Microsoft’s global Security Partner of the Year award, successfully launching our Overwatch SaaS platform which provides continual security configuration oversight and governance for Microsoft 365 and Azure, and receiving “exceptionally high” client satisfaction NPS metrics during due diligence.
While Threatscape continues to expand in Ireland, we are also seeing rapid growth in and into other markets. Already more than half of our team are based outside Ireland, with three offices and personnel in four countries. We secure critical IT assets in over 100 countries, across sectors including finance, tech, food, pharma, engineering, aviation, utilities, government and critical national infrastructure.
But most satisfying is the frequency with which team members recommend Threatscape to others as a great place to work, or with which clients proactively introduce us to their industry peers as their recommended cyber security advisor.
With the support of our new partner Horizon, we look forward to bringing the Threatscape ethos, expertise and focus on customer success to an even larger client base in the years ahead.”
