HOW WE HELP
Our cyber security consulting services help UK organisations identify risk, strengthen controls and make clearer security decisions. From focused assessments and architecture advice to compliance, testing and incident readiness, our consultants work alongside internal teams to deliver practical improvements without unnecessary complexity.
Our managed services combine expert consultancy, technical assurance and ongoing optimisation across cloud, endpoint, network and identity security. Working alongside your internal IT and security teams, we prioritise real risks, close critical gaps and strengthen resilience as your organisation grows.
AI-powered email security for Microsoft 365 and Google Workspace, delivered by Peritus and powered by Mimecast.
The service adds an independent layer of protection against phishing, business email compromise and impersonation, with secure email gateway and API-based deployment options.


Most vulnerability programmes prioritise the wrong assets. By default, everything is treated as equally important, meaning a domain controller can receive the same score as a development system.
Delivered by Peritus and powered by Qualys technology, the service applies asset context, threat intelligence and risk-based scoring to help security teams identify which vulnerabilities matter most.
The result is a clearer remediation plan focused on genuine business risk, rather than vulnerability volume alone.
Peritus provides continuous visibility into externally exposed assets, services and risks before attackers can exploit them.
Powered by AppCheck technology, the service continuously monitors your internet-facing footprint, identifies unexpected exposure and highlights changes that increase risk across cloud environments, applications, infrastructure and third-party services.
The result is a real-time view of your external attack surface, helping security teams detect exposure earlier, reduce blind spots and respond faster to emerging threats.
