About US


Our mission is to provide a secure and certain future for our clients. Keeping them protected so that they can go about their business is how we know we’re delivering on our promise.

We understand the immense challenge companies are facing to keep up to date with the ever-changing cyber threat landscape. ​

Maintaining an in-house IT security team can prove too costly for many organisations, but failing to address vulnerabilities can quickly destroy brand value and cost millions.

This is why we function as more than an external cyber security company, but act as a true extension of your IT security team.

Threatscape CEO Dermot Williams

Our Story

We are a pure play IT security company, which allows us to focus solely on protecting your business from cyber threats. We have offices in Dublin, London and Sheffield, and are the trusted security partner of enterprise clients with critical IT assets in over 100 countries around the world. 

While Threatscape has been in business since 2010, our management team collectively brings over 100 years of cyber security expertise to the table. 

Our Approach

Our expert team of engineers and consultants use their skills alongside best-in-class solutions to protect, detect and respond to the growing threat of cyberattacks. While our team has broad expertise in cyber security, we focus on endpoint protection, detection and response, cloud security, malware defence, identity protection, network and perimeter security.

We offer a range of professional services, managed security services including a 24×7 managed SOC, and are one of very few specialised security companies with a dedicated Microsoft Security Practice. 

Our Partners

We take security seriously; we only partner with a select group of trusted global IT security vendors. This ensures our team has a deep knowledge of the solutions we offer. This is critical because our in-house certified engineers support these technologies with full design, deployment, management and support.
