What RedDoor IT does
RedDoor IT Ltd is a privately held managed IT services provider headquartered in Croydon, United Kingdom, founded in 2010. The company delivers managed IT support, cybersecurity, and business technology services to small and medium-sized enterprises across South London, Surrey, and West Sussex, with a secondary office in Crawley and a wholly-owned subsidiary brand, CyberAdvisor, focused on Cyber Essentials certification.
The core technology stack centers on Microsoft 365 administration, cloud storage, hosted desktops, business connectivity (VOIP, mobile, broadband, landlines), and cybersecurity infrastructure built around Datto for backup/disaster recovery, Vonahi Security by Kaseya for vulnerability scanning, Webroot for endpoint protection, and Cisco firewalls. Service delivery is supported by a client portal for ticketing and 24/7 real-time reporting, with proprietary features including proactive monitoring and a Cyber Security Scorecard assessment tool. The company maintains certifications including Cyber Essentials, Cyber Essentials Plus (awarded May 2024), and NCSC Cyber Advisor status, and is an IASME-licensed Certification Body.
The business model combines recurring monthly managed service subscriptions (fully managed at approximately £100 per user per month, fixed-rate at approximately £50 per computer per month) with ad-hoc hourly support (£120/hour), pre-paid block hours (£100/hour), hardware and software resale, cybersecurity services, and connectivity resale. GTM is sales-led with direct outreach, location-targeted local SEO across multiple South London boroughs, content marketing via a company blog, and lead-generation tools including free vulnerability scans. The company claims a 99% customer retention rate and a 4.9/5 Google rating. In 2024, RedDoor merged with Tamite IT, expanding service capacity and client base.
